System safety and occupational safety considerations are frequently not considered early in a system's design process. Why is this? Some design engineers and project managers do not consider system safety and occupational safety issues as design engineering components (ex. design intent and how to achieve design intent do not require input from system safety and occupational safety professionals) Some design engineers and project managers believe that system safety and occupational safety considerations can be addressed once a system is in operation Some design engineers and project managers perceive that involving system safety and occupational safety professionals early in the design process will slow down the design process All of the above

*All of the above Unfortunately, many project managers and design engineers have no formal training in system safety and occupational safety and are unaware of the value (and ultimate savings) that can be realized by integrating such considerations

The science of measuring the human body for differences in various physical characteristics is: Kinesiology Anthropometry Physiology Ergonomics

*Anthropometry Anthropometry refers to the measurement of the human individual. Anthropometry involves the systematic measurement of the physical properties of the human body, primarily dimensional descriptors of body size and shape. Today, anthropometry plays an important role in industrial design, clothing design, ergonomics and architecture where statistical data about the distribution of body dimensions in the population are used to optimize products. Changes in lifestyles, nutrition, and ethnic composition of populations lead to changes in the distribution of body dimensions (ex. the obesity epidemic), and require regular updating of anthropometric data collections.

Workers compensation represents a significant business expense for employers. To a large extent, employers can influence their cost of this coverage by: Obtaining a low rate prospective experience rating plan Improving their experience modification rate Obtaining a low rate restrospective experience rating plan Negotiate with life underwriters

*Improving their experience modification rate One of the objectives of the Workers' Compensation system is to encourage safety in the workplace. A credit rating is awarded for better than average injury/illness accident prevention OR a debit rating charged against the premium for one that is worse than average. Injury rates and the experience modification are used to estimate charges. By lowering the experience modification rate one can lower their insurance premium.

The term incident encompasses first-aid cases, recordable cases, restricted workday cases, lost-workday cases, permanent disability cases, near misses and property damage cases. Which of the following represents an indirect cost? Incident review Workers' compensation premiums Ambulance Service Drug Testing

*Incident review Direct Cost Categories: 1. Workers' Compensation - Ex. WC premiums 2. Medical Bills - Ex. Treatment by physician, nurse, hospital costs 3. Medical Treatment Supplies - Ex. Bandages, splints, antiseptic 4. Ambulatory Service - Ex. Established fees 5. Drug Testing - Ex. Fees for off-site testing 6. Job Accommodations - Ex. Equipment or tool redesign or replacement; ergonomically designed chairs, keyboards 7. New Equipment - Ex. Cost of new equipment/parts purchased as a result of an incident Indirect Cost Categories: 1. Healthcare Professional - Ex. Consultation with the victim; treatment time; recordkeeping and filing; follow-up consultation(s) 2. Injured Worker - Ex. All time spent away from the job attributable to the incident. One way to determine this is to ask the nurse of supervisor. Be sure to include travel time to/from the nurse's office, waiting time, treatment and follow-up, and time spent visiting the offsite doctor's office. - Ex. An important, yet often overlooked contribution to indirect cost estimates is the percent reduction in efficiency due to restricted work. Often, an injured worker can return to the job at 100 percent; occasionally, however, the worker is only able to work at 90 percent until fully recovered. Once the percentage of restricted work has been determined, it can be incorporated into the direct cost summary. Example: Hourly rate = $10; cumulative time lost due to incident = 2 hours. This yields an initial $20 indirect cost. Ex. Restricted work efficiency level = 90% for 8 hrs. Since $10 x .9 yields work at a level for only $9/hr, there is a $1/hr indirect loss for each hour worked at the restricted level. Therefore, that $1/hr x 8 hrs yields an additional $8 loss, which should be added to the original $20 calculation; thus, the ultimate indirect cost is $28. 3. Supervisor - Ex. Consultation with the victim; recordkeeping and filing; follow-up consultation; disciplinary action 4. Return to Work - Ex. Consultation, work process modification 5. Lost Production/Productivity - Ex. Lost production represents the expected income that would have been received from maintaining production/service that was lost and is attributable to the incident. Often, this cost amounts to the highest of all indirect costs. Also consider the lost productivity of witnesses and colleagues in discussing and investigating the incident. 6. Incident Review - Ex. Sum hourly rates of the incident investigation team, multiply by the average time needed to complete a thorough investigation for each cost category. 7. Human Resources - Ex. Managing the case back to 100-percent duty, consultation, recordkeeping and filing. 8. Cost to Hire - Ex. The cost in terms of all necessary activities to bring in a replacement employee to work while the injured employee recovers 9. Manager - Ex. Consultation with the victim; recordkeeping and filing; follow-up consultation; disciplinary action 10. Process Delays/Interruptions - Ex. Represents lost income expected or lost personnel productivity when a process is delayed or interrupted as the result of an incident 11. Security - Ex. Since security is not involved in all cases, one must first determine the percentage of involvement. - Ex. Assume 900 cases occur and security is involved in 10 percent (or 90) of them. 90 cases x 1 hour of time devoted x $10/hr = $900 for all cases worked on. If security contributes $900 to the total, the cost for 900 cases = $900/900 = $1 contribution/case 12. Training - Ex. Include new or retraining efforts, instructor costs, paperwork, recordkeeping and tracking. For new/retrained employees on a new job, one can also perform an efficiency analysis similar to that of an injured worker (see above). 13. Legal - Ex. Calculate same as security costs

Which is a financial method for reducing the costs of accidents in an organization? Risk transfer Risk projection Financial risk management Hierarchy of loss controls

*Risk transfer Several control techniques available are for treating loss exposures. The two categories for reducing the costs of accidents in an organization: prevention (loss control) and financial (cost reduction). Loss control techniques include engineering, administrative controls and PPE to deal with losses. Engineering controls include building a ventilation system to reduce explosive vapor levels, whereas administrative controls might limit exposures to toxic materials. Issuing PPE such as respirators is the last line of defense against hazards in the workplace. Sprinkler systems and distance to a means of egress are examples of loss reduction not loss prevention. A company might try to avoid the loss altogether. Organizations can reduce exposure by substitution. Instead of mixing methylene chloride as a solvent ingredient in a commercial aerosol product a company count substitute a "safer" solvent to reduce the likelihood of a worker being exposed. Risk transfer assigns liability to another party, rather than run the risk of the loss itself. If methylene chloride mixing could not be accomplished safely in the plant, the company may choose to have the product shipped to a contractor who would mix the ingredient. If the contractor's workers are overcome by vapors from the solvent mixing, then the contractor would typically hold the liability. Another form of risk transfer is insurance. Insurance is designed to permit the company to shift the financial consequences of the risk to an insurance company. By paying the insurance company's premiums, the organization can expect specified benefits in the event of loss. With large numbers of insureds, insurance companies can more accurately estimate its own losses. Organizations may retain their loss exposures without dealing with them. This may be a result of ignorance or choice. Organizations that retain their own exposures may ignore them, or attempt to reduce them or they may, in fact, self-insure. Ignoring the risks may make the owners more confident, but dealing with the risks will make them more prepared for loss. Self-insurance is simply no insurance; the company retains the loss exposure. It should only be undertaken by companies with the financial resources necessary to absorb potential losses. (Friend & Kohn, 2007) Identification techniques include individual consultation and group discussion. Individual consultations are one-on-one meetings and are arranged as a preliminary exercise to initially identify the risks. This process involves key participants in the project in question. The purpose of this stage is to allow the interviewee to contemplate what he/she thinks are the main risks attached to either, the project as a whole, or as individual stages of the project or both. As the participants are from different disciplines, their viewpoints about the project are influenced by the specialized nature of their field. Group discussion is a process by which potential sources of risk are identified with a clear set of rules and a timetable. This technique should be carried out with the project team. One person should be the coordinator who chairs the meetings. The discussion process should have two distinct stages, a creative state and an assessment stage. The creative stage permits any one member of the team, one at a time to 'throw' in potential risks or sources of risk. Individual team members are not restricted to their own knowledge domain and outlandish ideas are encouraged. The assessment stage then follows. Estimation includes interviewing and brain-storming with personal and corporate experience. The analysis, and/or estimation, stage is more extensive in nature than in the identification stage. All the ideas are analyzed individually and a final draft of the risks is assembled. The idea of the analysis stage is to categorize or rank the risks by using the one-on-one situation in interviewing, or the group discussions from brain-storming. Therefore, the end result from this stage is to prioritize the risks so as to know which of them are to be forwarded to the quantitative analysis. At this point, this threshold level or cut-off point must also be decided. The notion being the risks below this level, and thus those not to be analyzed quantitatively, are covered by project contingent reserves. The ones above would not be, hence requiring further analysis. Personal and Corporate experience. If there are employees with experience, then this property should be utilized. Experience enables the main risks in a project to be identified. Obviously, one looks at the more senior officers to excel in this department. However, there is always a chance that certain risks never encountered before are overlooked. If the project is not equivalent to a previous project, than the policies of the company, or engineering judgment decides on a contingency percentage. Factors of safety are used extensively in the construction industry and is based on this method. Response strategies include: Risk avoidance Risk transfer Risk retention Risk reduction

Organizations allocate costs into various categories to aid decision making. Often, these costs are determined as a percent or ratio of manufacturing costs. Examples include raw materials, direct labor, indirect materials, selling costs, distribution costs, and other costs. In calculating return on investment of ergonomic controls, a key expense used to determine the cost-benefit of controls is Direct costs of accidents inflated over time to determine present value of future workers' compensation injury dollars The cost of capital associated with purchase and installation of controls Depreciation costs and pretax operating expenses after controls are implemented Profit and quality loss as a result of increased absenteeism and poor employee morale

*The cost of capital associated with purchase and installation of controls While all are important, the cost of capital (interest lost from the initial investment) is often ignored. Knowledgeable financial managers will consider the cost of capital when calculating their desired return on investment of capital expenditure. The challenge of the practitioner is to keep this in mind when determining cost-benefit of controls and, when possible, to quantify productivity efficiency and productivity enhancements to help support action plans

Audit:

A systematic, independent and documented process for obtaining information and data (audit evidence) and evaluating it objectively to determine the extent to which defined audit criteria are fulfilled. Internal audits, sometimes called first party audits, are conducted by the organization itself, or on its behalf, for management review and other internal purposes (ex. to confirm the effectiveness of the management system). Internal audits can form the basis for an organization's self-declaration of conformity. In many cases, particularly in small organizations, independence can be demonstrated by the freedom from responsibility for the activity being audited or freedom from bias and conflict of interest. External audits include second and third-party audits. Second party audits are conducted by parties having an interest in the organization, such as customers, or by other persons on their behalf. Third party audits are conducted by independent auditing organizations, such as regulators or those providing certification. Combined audit is when two or more management systems of different disciplines (ex. quality, environmental, occupational health and safety) are audited together. Joint audit is when two or more auditing organizations cooperate to audit a single auditee.

Prevention through Design

An effective fire loss control program must include objectives that prevent loss of life and personal injury, prevent inception of fire, protect property, and: Provide means to extinguish fire Provide uninterrupted operations Incorporate the use of fire resistive building materials Effect controls that limit the fire load (amount of combustibles)

Provide uninterrupted operations In any fire loss control program, there is a necessity for a plan that protects against a business interruption. Generally, there is a condition of insurance that you reduce the loss resulting from a business interruption by resuming complete or partial operations on the fire damaged premises and/or making use of other property and materials at another manufacturing facility

Res Ipsa Loquitur

Risk retention:

This is the method of responding to risks by the body who controls them. The risks, forseen or unforseen, are controlled and financed by the company or contractor that is fulfilling the terms of the contract. There are 2 retention methods, active and passive. Active retention, sometimes referred to as self-insurance, is a deliberate management strategy after a conscious evaluation of the possible losses and costs or alternative ways of handling risks. Passive retention, on the other hand, (sometimes called non-insurance) occurs through neglect, ignorance or absence of a decision, ex. a risk has not been identified and responding to the consequences of that risk might be borne by the contractor performing the work

Silicosis is

(also known as miner's phthisis, grinder's asthma, potter's rot and other occupation-related names[1], or by the invented name pneumonoultramicroscopicsilicovolcanoconiosis[2][3]) is a form of occupational lung disease caused by inhalation of crystalline silica dust, and is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs. It is a type of pneumoconiosis.[4] Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It may often be misdiagnosed as pulmonary edema (fluid in the lungs), pneumonia, or tuberculosis. Silicosis resulted in 46,000 deaths globally in 2013 down from 55,000 deaths in 1990.[5]

What is the lifting index for an operator to lift a 12kg weight and a recommended weight limit of 12.1? 0.526 0.992 1.008 1.901

*0.992 Lifting Index (LI) - a term that provides a relative estimate of the level of physical stress associated with a particular manual lifting task. The estimate of the level of physical stress is defined by the relationship of the weight of the load lifted and the recommended weight limit (RWL). An LI greater than 1 is considered a hazardous lift. LI = Load Weight/Recommended Weight Limit = L/RWL = L/RWL = 12/12.1 = 0.992

An inspector checklist for a dry-pipe sprinkler system requires opening the inspector test valve and timing before delay before water discharge. NFPA 13 requires that dry systems must deliver water to inspector test pipe outlet in not more than: 3 minutes 15 seconds 1 minute 30 seconds

*1 minute NFPA 13 establishes the maximum size for dry-pipe systems at 500 gallons for gridded systems and 750 gallons for non-gridded systems. However, these maximums can be exceeded if delivery of water to inspectors test pipe does not exceed 60 seconds. Many times to ensure rapid delivery of water, "quick opening" devices are installed. These devices generally consist of accelerators, which cause the deluge or dry pipe valve to cycle more rapidly or exhausters, which dump air more rapidly

a BTU is The amount of energy required to raise one kg of water 1degF 1/180 of the amount of energy required to raise the temperature of one pound of water from 32degF to 212degF The amount of energy needed to metabolize 1 lb of fat The amount of heat needed to raise the temperature of 1 lb of water from 32 to 212degF

*1/180 of the amount of energy required to raise the temperature of one pound of water from 32 to 212degF The amount of heat required to raise the temperature of water is a specific amount and varies with temperature. Answer B accounts for the change of heat capacity of water as its temperature changes, giving the average over the whole range of temperatures at which water is a liquid at 1 atm. The more common definition of a BTU is defined as the heat necessary to raise 1 lb of water 1degF

A generally accepted practice for use of a video display terminal is to locate the VDT slightly below the operator's horizontal line of sight (HLOS). The recommended angle suggested? 5deg below the HLOS 5-35deg below the HLOS 15-35deg below the HLOS 15-25deg below the HLOS

*15-25deg below the HLOS Although there is not complete agreement on this design principle, most references, including the NSC Accident Prevention Manual, suggest that 15deg to 25deg below the HLOS is the proper placement for video display terminals. This allows the operator to assume a normal head position that develops a slightly lowered sight or viewing angle. This means the video monitor top is placed at eye level to allow proper head and neck position.

You are evaluating a lifting task in your facility that involves moving tote boxes containing parts from a lower conveyor to an upper conveyor at right angles to each other. The tote boxes have 2 handles and are easy to grasp. The tote box handles, when on the lower conveyor, are 10 in. from the floor. When the tote box is on the upper conveyor, the handles are 40 in. from the floor. The center of the belt of both conveyors is 10 in. from the feet of the worker. One lift is required every minute during the full 8-hr shift. The tote box weighs 4 lb. How much material can be placed in the tote box?

*16 lb The NIOSH lifting equation is: RWL = LC * HM * VM * DM * AM * FM * CM LC = 51 lbs HM = (10/H) VM = [1-0.0075 * absolute value of (V-30)] DM = [0.82 + (1.8/D)] AM = (1-0.0032*A) **^ All of the above is part of the lifting equation before we start applying numbers from the problem** These are the numbers we will use in the RWL equation: H = 10 in. (this is the horizontal distance from the feet) V = 10 in. (this is the vertical distance from the floor) D = 30 in. (this is how far the item is lifted vertically) A = 90deg (this is the asymmetry AKA body twisting) FM = 0.75 (this is the frequency factor) CM = 1.00 (this is the coupling factor) RWL = (51 lb)*(10/10)*[1-(0.0075(absolute value 10-30)]*(0.82+(1.8/30)*(1-(0.0032*90))*0.75*1.00 = 51*1*0.85*0.88*0.712*0.75*1.00 = 20.37 lbs Product Weight = RWL-tote weight = 20.37-4 = 16.37 lbs

How many BTUs are required to raise the temperature of 1 lb of water from 32degF to 212degF?

*180 BTU 1 BTU is the heat required to raise 1 lb of water 1degF (assuming that the heat capacity of water remains constant throughout the temperature range). Energy = 212-32 = 180 Energy = 180degF * 1BTU/degF = 180 BTU

To construct an eye in a one-half inch wire rope, how many clips are required? 3 clips with U-bolts on live end 4 clips with U-bolts on live end 3 clips with U-bolts on dead end 4 clips with U-bolts on dead end

*3 clips with U-bolts on dead end Three clips are required, and the U-bolt or U-clip always goes on the dead end. The most common method of making a loop or eye in a wire rope involves the use of cable or "Crosby" clips. The Crosby clip consists of a U-bolt and saddle and if used correctly produces an excellent connection. However, even one loose or incorrectly applied clip reduces the efficiency of the connection by as much as 50%. The U-bolt should always be installed bearing on the dead end of the rope with the saddle bearing on the long or live end of the rope. This is because the U-bolt when tightened, dents and damages the wire rope. All clips should be installed in the same manner. Additionally, the ridges or corrugation in the saddles must match the lay of the rope ex. right lay or left lay. Otherwise the live end of the rope will also be damaged resulting in broken and cut strands. The number of clips required usually ranges from 3-7 depending on material and size of wire rope. One reference is OSHA 1926.251 Hint: Never saddle a DEAD horse

A small automobile traveling at a constant velocity of 55 mi/hr accelerates to pass a tractor-trailer. The tractor-trailer is 60 ft long and is also travelling at 55 mi/hr. Assuming that the driver of the small automobile accelerates to a constant velocity of 70 mi/hr when he pulls into the left lane 20 feet BEHIND the tractor trailer, how far will the small automobile actually travel in the left lane until it is 60 ft in FRONT of the tractor trailer and moves back into the right lane? 350 ft 450 ft 550 ft 650 ft

*650 ft determine the relative distance that the small automobile must travel. this is the length of the tractor-trailer plus the buffer distances behind and in front of the tractor-trailer. 60 ft + 20 ft + 60 ft = 140 ft determine the relative velocity at which this distance will be traveled by the small automobile. this is the difference between the tractor-trailer's velocity and the small automobile's velocity. in other words, this is the velocity at which the small automobile appears to be traveling relative to the driver of the tractor-trailer. 70 mph - 55 mph = 15 mph for how long will the small automobile need to travel 140 ft (the relative distance) at 15 mph (the relative velocity)? convert 15 mph to ft/sec. 15 mi/hr *5280 ft/mi * 1 hr/3600 sec = 22 ft/sec divide 140 ft / 22 ft/sec = 6.36 sec = the small automobile will traverse this distance in 6.36 sec how far did the small vehicle actially travel at 70 mph for 6.36 sec? s = vt + at^2 / 2 no acceleration (constant velocity), so the at^2/2 term is 0 70 mi/hr * 6.36 sec * 5280 ft/mi * 1 hr/3600 sec = 653 ft (the last 2 terms are conversion factors)

You are preparing a driver's training course and want to discuss the danger of excessive speed while driving. When driving, a driver's reaction time in an emergency is divided into three parts: the time required for the driver to recognize the presence of an emergency, the time required for the driver to make a decision on how to handle the emergency, and the time required for the driver to actually implement the decision. You discover that the combined total of these segments is about 0.6 seconds for the average, unimpaired driver. How far will an automobile going 80 mi/hr travel during 0.6 sec?

A more detailed definition is "a potential condition, or set of conditions, either internal and/or external to a system, which when activated by a stimulus (set of events or conditions that transforms a hazard from its potential state to one that causes harm to the system) or series of events which culminate in a loss (accident)"

To discharge a capacitor safely, which tool should be utilized? A screw driver to short circuit the terminals An approved leakage meter A properly rated bleeder resistor or capacitor discharge tool Properly rated test light or light bulb

*A properly rated bleeder resistor or capacitor discharge tool It is essential that large or high voltage capacitors be fully discharged before measurements are made, soldering is attempted, or the circuitry is touched in any way. Some of the large filter capacitors commonly found in line operated equipment store a potentially lethal charge. Capacitors (like the high voltage of the CRT in a TV or video monitor) will retain a dangerous or at least painful charge for days or longer. The main filter capacitors in the low voltage power supply should have bleeder resistors to drain their charge relatively quickly, but resistors can fail. There is no discharge path for the high voltage stored on the CRT capacitance, other than the CRT beam current and minimal reverse leakage through high voltage rectifiers. In the case of old TV sets using vacuum tube HV rectifiers, the leakage was essentially zero. They hold their charge almost indefinitely. When a capacitor is safely discharged, some capacitors, due to their ability to leak, are "dead" after being safely discharged with a "bleeder resistor" of the right value for the job. Using a resistor that is under-rated, wattage-wise, can result in the bleeder going open circuit during a discharge sequence leaving some energy. High voltage capacitors, or worse yet, high energy-high voltage capacitors require correct wattage AND correct resistance to be bled safely. Also, high microfarad low voltage capacitors can vaporize a screwdriver and spray metal into a person's eyes. (Adequate voltage margin is also essential for resistors used in high voltage circuits. Low inductance capacitors that are used in energy pulse circulatory, are often of the oil-filled high energy/high voltage type. This type can give a shock after it has been completely drained by a safe bleeding technique. Never attempt to discharge a capacitor without protective goggles shielding eyes and gloves that are NFPA 70E compliant. Using the right tools and materials for discharging the capacitor is very crucial. Discharging a capacitor simply means giving the stored electrical currents a path out of the apparatus. To discharge a small capacitor, touching the two lead terminals with the tip of screwdrivers with insulated handles should discharge; however, this is not recommended. Attach a properly rated resistor or capacitor discharge tool onto the capacitor's terminals to safely dissipate the stored electrical currents. To verify the capacitor is completely discharged, use a volt meter or test light.

A quantitative risk analysis (QRA) was performed on a single process. The results of the analysis indicate that the process will fail, causing catastrophic consequences once every 10,000 years. Your plant has seven of these processes operating at all times, and your company has 11 other plants similar to this one around the country. Also, your company has three other competitors with similar numbers of facilities with very similar processes. Assuming that the results of the QRA can be extrapolated to the other similar process throughout the industry, how often should you expect a catastrophic accident in your company's industry related to this process? About once every 30 years About once every 80 years About once every 150 years About once every 180 years

*About once every 30 years The results of the QRA are associated with a single process. Your company has 84 of these processes (12 facilities x 7 processes/facility). Your company's competitors bring in another 252 such processes (84 processes x 3). This is a total of 336 such processes in the industry. That means we can expect 336 catastrophic accidents in 10,000 years, or about one accident every 30 years

One of the new principles of safety management states that certain sets of circumstances can be predicted to produce severe injuries. Which of the following does NOT apply? High energy sources Nonproductive activities Usual, nonroutine activities Accidents are by chance and cannot be predicted

*Accidents are by chance and cannot be predicted The traditional approach to safety states that once an accident occurs, the severity of injury is dictated by chance. The new principle states that certain sets of circumstances can be predicted to produce severe injuries. Essentially, we can attack severity directly instead of hoping the attach on accident frequency will also affect severity.

Water is immediately available in sprinkler piping in a wet pipe system in the event of fire. The sprinkler head fuse is melted by heat from the fire and water is delivered to control or extinguish the ensuing fire. In a pre-action fire sprinkler system: Air under pressure is maintained in the system piping Piping includes open sprinklers Building occupant manually opens a deluge valve, thereby taking pre-action Sprinkler heads are connected to a rate of rise detector which assures a dual fault tolerance

*Air under pressure is maintained in the system piping In a pre-action fire sprinkler system, system piping is pressurized. The piping is charged through the activation of supplemental detection systems located in the same area as the sprinklers. Water is then free to flow through the piping to sprinkler heads. If a sprinkler head has fused (through heat from a fire) water will be delivered to the fire. Pre-action systems are used when there is a danger of serious water damage to the protected area. Calcium carbide combines with water to create the corrosive calcium hydroxide and liberates acetylene (ethyene). Therefore it is not recommended to use a water system with calcium carbide.

*Compliance with OH&S legal requirements is only a piece of an OH&S management system conforming to the Occupational Health and Safety Management Systems standard 18001 Section 4.3.2, of the standard requires that legal and other requirements be continually identified and taken into account when establishing processes, procedures and running an OH&S management system

Which action, according to current safety philosophy, would have the greatest impact on changing safety behavior? Posting a sign stating, "Wear Your Eye Protection" Turning off all machines when finished Complimenting an employee for wearing eye protection Providing a free meal for a safe month on the plant floor

*Complimenting an employee for wearing eye protection Most experts agree that there are two primary actions that influence behavior change the most, positive reinforcement and reinforcing the behavior as close to action time as possible. The first step in improving behavior in an organization is to establish an ethics program to address the organization culture issues. Safety incentive programs should be designed to influence and change behaviors. Positive Feedback/Compliments have 3 parts: 1. Soon 2. Certain (Specific) 3. Positive

The term CLI used in the professional practice of ergonomics means Composite Lifting Index Controlled Lifting Index Coordinated Lifting Indicator Coupling Lifting Index

*Composite Lifting Index CLI is the term used in the revised NIOSH Lifting Equation to denote the overall lifting index for a multi-task manual lifting job. The multi-task procedure is quite complicated and involves calculation of the Frequency-Independent Recommended Weight Limit (FIRWL), the Single-Task Recommended Weight Limit (STRWL), the Frequency-Independent Lifting Index (FILI) and the Single-Task Lifting Index (STLI) for each task

An electrical conduit that is very warm to the touch is discovered during an industrial safety inspection. Which of the following descriptions best fits this condition? Conduit is hot with electric energy due to a ground fault Conduits are always warm to the touch Conduit is likely absorbing radiant heat from the furnace Conduit likely contains overloaded electrical wiring

*Conduit likely contains overloaded electrical wiring One of the most common causes of electrically created fires is overheated wiring because of overloading. Many factors contribute to a safe installation. The wire must be sized (correct gauge) properly to handle the current. Overcurrent protection (fuses or circuit breakers) must also be correctly sized and function properly. Additionally, electrical raceways must not be overloaded with electrical wiring. The sizing of wiring and the amount of wiring allowed for a given size of raceway is strictly regulated in the National Electric Code. Generally conduit will not feel hot to the touch even under severe circuit loading if installed according to code.

which of the following is the best way to reduce unsafe acts? The swift and sure application of negative reinforcement for unsafe acts Studying the behavior pattern and its underlying root causes Consistently applying positive consequences to reinforce appropriate behavior Encouraging behavior avoidance through the application of rewards

*Consistently applying positive consequences to reinforce appropriate behavior studies have shown that the systematic positive reinforcement of appropriate behavior (including behavioral changes) is highly effective toward improving employee attitudes and behavior

You are a safety professional in a large corporation with a high-rise corporate office building. The building is occupied totally by employees of your company except for a few service contractors and first floor space leased by store tenants. Life safety is one of your principle concerns. Strategies for evacuation that you may consider include all the following EXCEPT: Relocating occupants Constructing a vertical exit Constructing a horizontal exit Staging, or phasing, the evacuation

*Constructing a vertical exit Relocation means to move people away from the fire floor, generally two floors up or down from the fire. A horizontal exit on the same floor is possible when fire walls, ceilings, and floors exist that allow people to evacuate through a fully protected enclosure before arriving at a stairwell. Staged evacuation can take several forms but essentially means to evacuate people in stages and to perhaps use a series of safe areas in the staging. There is no such term as a vertical exit.

Risk analysis generally consists of all of the following steps except Estimation of the likelihood of events Construction of a fault tree Estimation of the consequences Selection of specific scenarios

*Construction of a fault tree One doesn't have to construct a fault tree to conduct a risk assessment. However, event flow should be defined. The other 3 steps are referred to ask the "RISK TRIPLET"

You are conducting a formal safety inspection of a manufacturing plant with your newly hired safety engineer. During your inspection you observe an employee, without eye protection, working at a bench installing parts. This is not a hazardous operation but it is in a posted "Eye Protection" area. Which one of the following is the best course of action? Contact the supervisor and discuss the situation Test the skills of your new safety engineer by letting him handle the situation Confront the employee and determine "Why" eye protection is not being used Note the discrepancy and do not discuss it until the outbrief when the CEO and the supervisor are both present

*Contact the supervisor and discuss the situation

When an injured person's care for his own safety was less than that reasonable for a prudent person under existing conditions, he is considered negligent and the defendant will not be held liable. This principle is known as: Privity Contributory negligence Joint tort Assumption of risk

*Contributory negligence The injured person contributed to the injury because he took less than reasonable care

Based on the results of the Process Hazard Analysis, the various procedures for the process should identify the hazards with the materials and processes as well as the accident consequences. These considerations should contain at a minimum: properties of the chemicals used; precautions to prevent exposure; any special or unique hazards that may exist and _____. Control measures for physical contact hazards Control measures to be taken if physical contact or airborne exposure occurs A Hazard Control Program Plan Engineering controls listing

*Control measures to be taken if physical contact or airborne exposure occurs

Employees are interviewed randomly to collect accident information concerning near misses, difficulties in operations, and conditions that could have resulted in death, injury, or property loss. This method is described as Behavior sampling Critical incident technique Program quality verification inspection Un-programmed process safety management

*Critical incident technique The critical incident technique asks those participating to describe any incidents that come to their attention. This technique can be useful in investigating worker-equipment relationships in past or existing systems, evaluating modifications to existing systems, or developing new systems. Safety sampling can be a successful method to verify effectiveness of a safety training program provided that the technique is adapted to the program, a sound basic accident prevention program is in place and management is familiar with the technique and it's potential.

A person who keeps, maintains, transports, or stores a dangerous creature, device or substance is liable for injury or damage, regardless of fault, even when he exercises due care. This principle is known as: Care Dangerous privity Dangerous instrumentality Res ispa loguitur

*Dangerous instrumentality If a person keeps, transports, etc. dangerous "things" they can be held liable under this principle

A group of foundry workers are exposed to an air temperature of 105degF. Which control would be least appropriate? Wear more clothing Decrease the air movement Increase air velocity Decrease the humidity

*Decrease the humidity Wearing more clothing is a physical barrier that blocks radiant energy (i.e. energy in the form of electromagnetic radiation). Air movement and humidity have almost nothing to do with radiant energy control (though they do have a lot of effect with convective energy control). You still get sunburned when the wind is blowing or the humidity is high or low. You don't if you have clothes on (or some other UV barrier). Infrared radiant energy is simply a lower wavelength of the same kind of energy. Instead of causing burns, it just heats the skin.

A rapid reaction during which heat is transferred progressively from a reaching material to another nearby whose temperature is then raised to a point at which it also reacts; is called: Reaction terminal Deflagration Detonation Explosion

*Deflagration

Manual materials handling tasks can be designed to avoid injuries. Modifications to the object to be handled could include all of the following EXCEPT Design objects so the arms can be easily extended around it Handles or hand holds should be used wherever possible Avoid lopsided weights and loose contents Use hoists or other lift assists when object weight is excessive

*Design objects so the arms can be easily extended around it Extension of the arms around objects should be avoided. Alternatively, use handles, lifting devices, and even weighting to improve the task

What would be an example of an engineering control? Design the job to fit the worker Assign workers to specific jobs Implement a job rotation schedule Providing customized fitted gloves

*Design the job to fit the worker One of the best ways to prevent and control occupational injuries, illnesses, and fatalities is to "design out" or minimize hazards and risks. NIOSH leads a national initiative called Prevention through Design (PtD). PtD's purpose is to promote this concept and highlight its importance in all business decisions. The mission of the PtD National initiative is to prevent or reduce occupational injuries, illnesses, and fatalities through the inclusion of prevention considerations in all designs that impact workers. The mission can be achieved by: - Eliminating hazards and controlling risks to workers to an acceptable level "at the source" or as early as possible in the life cycle of items or workplaces - Including design, redesign and retrofit of new and existing work premises, structures, tools, facilities, equipment, machinery, products, substances, work processes and the organization of work - Enhancing the work environment through the inclusion of prevention methods in all designs that impact workers and others on the premises PtD encompasses all of the efforts to anticipate and design out hazards equipment, tools, products, new technologies, and the organization of work. The focus of PtD is on workers who execute the designs or have developed to support designing out hazards, the most reliable and effective type of prevention

Experience has indicate the most effective way to reduce accidents is: Training employees to be more safety-conscious Behavior modification Designing safety features into systems Job rotation

*Designing safety features into systems Hazards can be more effectively reduced or eliminated through system design, whereas hazard reduction through changing human behavior is limited and requires continuous reinforcement

when designing an ergonomically desirable work place, which of the following is a good design practice? Allowing room for employees to lean forward or to the side to reach objects Designing the work so that employees can move about and use different muscle groups Placing objects within close reach to discourage movement Designing work which requires the arms to be held up or out

*Designing the work so that employees can move about and use different muscle groups helps prevent overuse of any one muscle group. leaning, restricted movement, and extension of arms all can cause injury over the long-term

The audit objectives define what is to be accomplished by the individual audit and may include which of the following? Evaluation of the ineffective monitoring of audit program outcomes Determination of the extent of non-conformity of activities, processes and products with the requirements and procedures of the management system Conformity with audit program procedures Determination of the extent of conformity of the management system to be audited, or parts of it, with audit criteria

*Determination of the extent of conformity of the management system to be audited, or parts of it, with audit criteria Each individual audit should be based on documented audit objectives, scope and criteria. These should be defined by the person managing the audit program and be consistent with the overall audit program objectives. The audit objectives define what it is to be accomplished by the individual audit and may include the following: - determination of the extent of conformity of the management system to be audited, or parts of it, with audit criteria - determination of the extent of conformity of activities, processes and products with the requirements and procedures of the management system - evaluation of the capability of the management system to ensure compliance with legal and contractual requirements and other requirements to which the organization is committed - evaluation of the effectiveness of the management system in meeting its specified objectives - identification of areas for potential improvement of the management system The audit scope should be consistent with the audit program and audit objectives. It includes such factors as physical locations, organizational units, activities and processes to be audited, as well as the time period covered by the audit. The audit criteria are used as a reference against which conformity is determined and may include applicable policies, procedures, standards, legal requirements, management system requirements, contractual requirements, sector codes of conduct or other planned arrangements.

For budgeting purposes, how do you calculate the value of a loss control program (neglecting the time value of money)? One cannot calculate the value of a loss control program since one cannot place a value on human injury or death Determine the initial and recurring costs of the loss control program Determine the expected magnitude of loss reduction Determine the expected magnitude of loss reduction and subtract the initial and recurring costs of the loss control program

*Determine the expected magnitude of loss reduction and subtract the initial and recurring costs of the loss control program The value of a loss control program is the result of the expected magnitude of loss reduction, minus the initial and recurring costs of the loss control program

Which of the following, according to the NSC, is not included in good accident investigation procedures? Identify basic causal factors Determine who is to blame for the accident Identify deficiencies in management system Suggest corrective action alternatives for management system

*Determine who is to blame for the accident According to the NSC, good accident investigation procedures: - provide information needed for injury rates, identify trends or problem areas, permit comparisons and satisfy workers' compensation requirements - identify, without placing blame, the basic causal factors that contributed directly or indirectly to each accident - identify deficiencies in the management system - suggest corrective action alternatives for a given accident - suggest corrective action alternatives for the management system - In reconstruction of a vehicle accident, the most important element is to consider the possibility of multiple causes

A tornado has just struck your multi-building facility where you have several hazardous processes operating. There appears to be substantial damage; however, you are unharmed. Since the coordinator of emergency management is not onsite, what are your first priorities as the acting emergency management coordinator? Safeguarding personnel at all costs while abandoning all systems Shutting down all systems and evacuating the site Determining the local emergency response incident commander and turning over incident command to that person Safeguarding personnel and safeguarding all systems, without further endangering other personnel

*Determining the local emergency response incident commander and turning over incident command to that person There should never be a question about safeguarding personnel and safeguarding the public in any situation. However, emergency planning requires organizations to consider how the organization's property, operations, and the environment can also be safeguarded in an emergency

If the velocity of reaction through the reacting material reaches sonic or supersonic speed, the explosion is called: Low order explosion Low explosive Deflagration Detonation

*Developing a conceptual model of the system An analysis of the system can clarify a complex process by devising a chart or model that provides a comprehensive, overall view of the process by showing its principal elements and the ways in which they are interrelated.

Methods of minimizing rates of repetition in jobs include all of the following EXCEPT Dividing jobs to reduce the number of job elements Allow alternate use of limbs Allow self-pacing Allow frequent rotation between jobs which use different postures and muscles

*Dividing jobs to reduce the number of job elements The goal is to increase the number of job elements to reduce the repetitiveness of the task. This can only be done by combining jobs, not dividing them. The other answers help to reduce repetition through allowing change and alternative to using the same muscles continuously

Hazardous locations are classified as Class I, Class II, or Class III, depending on what type of hazardous substance is or may be present. Each of these classes is divided into two hazard categories, Division 1 and Division 2, depending on the likelihood of the presence of a flammable or ignitable concentration of a substance. Which one of the following statements is false? Division 1 locations are designated as such because a flammable gas, vapor, dust or easily ignitable material is normally present in hazardous quantities Division 2 locations are designated as such because a flammable gas, vapor, dust or easily ignitable material is normally present in hazardous quantities Division 2 locations, the existence of hazardous quantities of these materials is not normal, but they may occasionally exist either accidentally or when material in storage in handled In general, the installation requirements for Division 1 locations are more stringent than for Division 2 locations

*Division 2 locations are designated as such because a flammable gas, vapor, dust or easily ignitable material is normally present in hazardous quantities

*During manual lifting and to evaluate the effects of body postures Body postures are an important consideration when performing biomechanical analyses

The National Electric Code (NEC) utilizes a Class I, II, III etc. hazard identification system. Class II hazards involve: Flammable liquids Dusts Fibers Powders

*Dusts Class I - flammable liquids or gases Class II - combustible dusts Class III - fibers

Who must be trained on the methods and means necessary for energy isolation and control of hazardous energy? Area supervisor Each authorized employee Each affected employee All employees whose work operations are or may be in an area where energy control procedures may potentially be used

*Each authorized employee In the OSHA lockout/tagout (LOTO) standard (29 CFR 1910.147) an authorized employee is one who locks out or tags out the machine or equipment in order to perform servicing or maintenance. An affected employee is one whose job requires him/her to operate or use a machine or equipment on which service or maintenance is being performed under LOTO, or whose job requires him/her to work in an area in which such servicing or maintenance is being performed. Authorized employees must receive training in the recognition of hazardous energy sources, the type and magnitude of the energy available in the workplace, and methods and means necessary for energy isolation and control. Affected employees need training in the purpose and use of energy control devices. The most significant item in safe operating procedures for for equipment maintenance is ensuring that energy at the machine is zero and will remain that way during the repair. A review of 29 CFR 1910.147 is recommended if unfamiliar with OSHA's LOTO requirements.

What is the most expedient method of protecting a worker from noise? Ear protection Limited exposure time Engineering controls Administrative controls

*Ear protection is the quickest way to provide hearing protection. The most effective long term solution is to engineer out the source of the noise (if feasible).

The leading cause of industrial fires is attributed to: Friction (machine bearings) and overheated materials (run-away process temperatures) Careless smoking Electrical (wiring, panels, apparatus) Incendiarism (arson)

*Electrical (wiring, panels, apparatus) Over a recent period of 10 years and 25,000 fires, 23% of the fires they analyzed were attributed to be of an electrical nature

The time required for a flammable mixture to ignite is dependent upon: Pressure, temperature, and oxygen Temperature, composition, pressure Energy of ignition source, temperature, pressure Energy of ignition source, temperature, pressure, and composition

*Energy of ignition source, temperature, pressure, and composition Generally, the entire mixture is not brought to autoignition temperature at once. Local heating occurs so that a small volume is first brought to autoignition temperature and ignites.

Management is committed to reducing accidents and has embraced the concept of performing root cause analyses on all accidents and near misses. Currently, you estimate that about one out of every ten minor accidents is reported (minor accidents do not require professional medical intervention). Likewise, you believe that more than 4 near misses have ever been reported in 4 years. You know that getting employees to report minor accidents and near misses is fundamental to preventing accidents through root cause analysis. Which of the following is NOT suitable for encouraging employees to report accidents and near misses? Ensuring employees see operational/management system changes as a result of the root cause analysis Ensuring that the root cause analysis process will never blame employees Ensuring that employees can easily report accidents and near misses without complicated paperwork and explanations Ensuring each employee is recognized for the number of near misses he/she reports

*Ensuring each employee is recognized for the number of near misses he/she reports Employees who report accidents and never see any resulting good come from the report are not likely to go to the trouble of reporting any further accidents or near misses. The root cause analysis process MUST be blame-free or employees will not make reports. The root causes of accidents are management system weaknesses - employees who perceive the root cause analysis process as a way to "get" employees will never participate in it. If the reporting process is complicated and requires the employees to spend a lot of time with complicated forms and explanations, then employees are not likely to continue reporting accidents and near misses. Finally, peer pressure is a key reason employees do not report accidents and near misses. Recognizing employees for such things is akin to embarrassing them publicly.

The responsibility for a defective product as it moves from the manufacturer to the customer rests with the ____. Manufacturer Distributor Wholesaler Entire chain from raw material on

*Entire chain from raw material on can be held liable for a defective product

In reviewing designs for product safety, the foremost environmental consideration(s) must be directed to the affect of: Environmental conditions on product operations Product operations on the environment Product disposal on the environment Environment

*Environment The environment must be considered in designs for product safety because the ambient environment (temperature, humidity, corrosivity) will affect the condition and operation of the product; the operation of the product (noise, particles, toxic vapors, liquid effluent) would, without proper controls, pollute the environment; and product disposal, should it contain hazardous materials (mercury, lead, beryllium) has the potential to contaminate soil and groundwater.

What is the key to effective safety management? Compliance with OSHA standards Establishing accountability Engineering control of workplace hazards Safety Committees

*Establishing accountability management must hold supervisors accountable for the unsafe acts committed by the employees they supervise

Which of the following is the first step in establishing an effective process safety management program? Employee training Hazard analysis Written process safety management program Establishing the safety culture

*Establishing the safety culture An effective process safety management program cannot be achieved without first establishing a culture in which safety is a priority and is part of the daily routine of the employee. The hazard analysis and written program will not be implemented, and employee training is not effective without the commitment of the work force or management.

You happen to be in the building at the time of an industrial fire emergency. The fire department has been notified, the building alarm has activated, and you are attempting to extinguish the incipient fire with a nearby 20-pound dry chemical fire extinguisher in accordance with your training. You are unsuccessful. You should Evacuate and await the fire department Search for another fire extinguisher and make another attempt to extinguish the fire to provide time for the fire department to arrive Remain near the fire to prevent evacuating people from inadvertently entering the danger area Enter the fire and smoke area to search for trapped people

*Evacuate and await the fire department Holding paramount the safety and health of people requires you to hold paramount your own safety. Even though the other 3 answers imply you are holding paramount the safety and health of people, each of the other 3 disregards your own safety

In the case of short term spills, in-place protection is used when? Evacuating the public would cause lesser risks Evacuating the public would cause greater risks Is not recommended Is not feasible of short term spills

*Evacuating the public would cause greater risks or when an evacuation cannot be performed. (1993 Emergency Response Handbook)

This analysis considers initiating events, their consequences through consideration of system failure and success alternatives. It is called: Event tree analysis Fault tree analysis Cause consequence analysis Event/causal analysis

*Event tree analysis is an analytical tool that can be used to organize, characterize, and quantify accidents in methodical order; considering success and failure states

Every person has a legal duty to exercise due care for the safety of others and to avoid injury to others if possible; this principle is called: Exercise of due care Slight care Non gross negligence Great care

In developing a safe maintenance guide for robotic workstations, which method, useful for predicting potential injury situations, would apply to: determining the combinations of human actions and equipment conditions that could lead to a robot related injury? SADT JSA FTA FMECA

*FTA Fault tree analysis begins with defining the unwanted injury event and proceeds graphically constructing the sequences of events and conditions that would lead to that event. When failure rates and human reliability values are available, the probabilities of the various sequences can be computed.

A design which allows the system to function safely until corrective action is possible is called: fail safe fail passive fail operational fail non-operational

*Fail operational

Which of the following designs will NOT allow equipment to operate? Fail active Fail passive Fail safe Fail operational

*Fail passive

A system that is designed to shut down when one or more critical components fail is called Fail safe Interlock Circuit breaker Fuse

*Fail safe There are times when a system, guard, elevator, and other high risk equipment are designed to shut down when one or more critical components fail. When this occurs, it will do so in a safe position or condition without the experience of a major loss

What is the design that attempts to ensure that a failure will leave the product unaffected or will covert it to a state in which no injury or damage will occur? Fail-safe Fail-secure Fail-operations Fail-proof

*Fail-safe According to Willie Hammer, Product Safety Management and Engineering, there are three fail-safe designs: A. Fail-passive arrangements reduce the system to is lowest energy level B. Fail-active design maintains an energized condition that keeps the system in a safe mode until a corrective or overriding action occurs or an alternate system is activated C. Fail-operational arrangements allow functions to continue safely until corrective action is possible. An example of a fail-active device would be a battery-operated smoke detector that chirps when it is time to replace the battery.

The hazard analysis method that tabulates the ways in which equipment and components can fail, and the effects of these failures on a system, process, or plant is called? Hazard and Operability (HAZOP) Fault Tree Analysis (FTA) Failure Mode and Effects Analysis (FMEA) Management Oversight & Risk Tree (MORT)

*Failure Mode and Effects Analysis (FMEA) The Failure Mode and Effects Analysis (FMEA) tabulates the ways in which equipment and components can fail, and the effects of these failures on a system, process, or plant. Failure modes describe the ways in which equipment can fail (such as open, closed, on, off, leaks, etc.). The analyst lists all of the components of the system under review and all the failure modes for these components. The FMEA identifies the individual failure modes that can either cause or contribute to an accident. This method of analysis does not address multiple failures. An FMEA analysis should produce a qualitative, systematic, list of equipment and components, a list of associated failure modes, and a list of the effects of the failure modes on the system. The list of effects should include a worst-case estimate of the consequences of each failure mode. The information produced by an FMEA analysis can be used to support recommendations for increased equipment and component reliability that would improve safety.

A method that tabulates each system or unit of equipment, along with its failure, the effect of each failure on the system or unit, and the degree of risk posed by the individual failure is called: Failure effects analysis Failure modes and effects analysis Fault tree analysis Failure hazard analysis

*Failure modes and effects analysis defined above as applied in Process Safety. Note that there are extensive inductive versions of FMEA, such as Failure Modes and Effects Critality Analysis (FMEACA) which is utilized within aerospace reliability analysis. Criticality is an attempt to define the System Safety related risk associated with the specific failure.

The technique in which the failure or malfunction of each component is considered and the effects of the failure traced throughout the system is identified with: Failure modes effects analysis Fault hazard analysis Fault tree analysis THERP

*Failure modes effects analysis is an analytical technique in which the failure or malfunction of each component is considered, including the mode of failures. The effects of the failure are traced through the entire system and its effects on the system performance is evaluated. Failure modes effects analysis is very similar to failure hazard analysis, except it is performed for every component in the system without regard for outcome.

Which of the following methods is a deductive analysis technique that allows the analyst to determine the combinations of failures that are necessary to achieve an event defined as the top or undesired event? Fault Tree Analysis (FTA) Failure Mode and Effects Analysis (FMEA) Hazard and Operability (HAZOP) Risk Management Plan (RMP)

*Fault Tree Analysis Key word: Deductive FTA is a deductive analysis technique that allows the analyst to determine the combinations of failures that are necessary to achieve an event defined as the top or undesired event. FTA is well suited for the analysis of highly redundant systems. The fault tree is a graphic model that displays the various combinations of equipment/component failures and human errors that can give rise to the top event. The FTA provides a means to qualitatively or quantitatively identify the frequency of the top event. It is a deductive technique that employs Boolean Logic (the use of AND and OR gate logic) to relate the top event to a combination of basic events that must occur in order for the top event to happen. The fault tree, once constructed, can be quantified by using the failure rate data for the basic events (ex. those events at the bottom of the tree). A quantified fault tree projects the rate of occurrence for the top event.

The technique that selects the undesired outcome and all possible modes of happenings is the: Failure modes effects analysis Fault tree analysis Fault hazard analysis THERP

*Fault Tree analysis In the fault tree method, an undesired event is selected and all possible happenings that can contribute to the event are diagrammed in the form of a tree. The branches of the tree are continued until independent events are reached. Probabilities are determined for the independent events and after simplifying the tree, both the probability of the undesired event and the most likely chain of events leading up to it can be computed

The system safety technique that starts with an undesired event and analyzes the way the undesired event occurs is: Event tree Fault tree Pert Job safety analysis

*Fault tree starts with the undesired event AKA the FAULT

A system safety technique that starts with an undesired event and an analysis of how that event can occur is called: Fault tree analysis Boolean algebra Preliminary hazard analysis A & C

*Fault tree analysis starts with an undesired event and analyses its antecedents

The manufacturer of any product faces an environment in which: Fault without negligence exists Present court rulings favor the company Product liability is not a significant financial burden Product liability claims are generally decreasing

Which of the following is not correct? Intensity - How much light a source gives off in a given direction Lumen - unit of light output from a light source Footcandle - Quantity of a light falling on a surface Footlambert - How much light is reflected from a surface

*Foodlambert - How much light is reflected from a surface Footlambert - Amount of light emitted or reflected from a surface. A surface emitting one lumen per square foot of surface has a luminance (brightness) of one footlambert. Reflectance - How much light is reflected from a surface. A perfectly white surface has a reflectance of 1 or 100%

Good ergonomic design for standing workstations would include the following EXCEPT Opportunity for frequent adjustments in posture Anti-fatigue floor mats Foot rests or a bar rail Foot controls for adjustments of work

*Foot controls for adjustments of work Foot controls should be avoided for standing workstations, since this can cause shifting of weight to one leg and abnormal postures. Frequent adjustments, floor mats, and foot rests allow the employee to pick and choose the most comfortable position as needed.

Any foreseeable act that places a rescuer in the same danger as an injured person the rescuer is attempting to aid is considered negligence by the person who committed the initial act. This principle is called: Foreseeability Foreseeability applied to rescue Foreseeability for safety Inherent danger

*Foreseeability applied to rescue allows damages to rescuer if someone could have foreseen that their actions were going to cause an incident where aid would be needed

Which of the following is the best statement related to audit documentation? Checklists must always be used. Forms to record supporting evidence must be documented. Audit sampling plans are generally not documented. Chain of custody is not a legal form of documentation.

*Forms to record supporting evidence must be documented The audit team members should collect and review the information relevant to their audit assignments and prepare work documents, as necessary, for reference and for recording audit evidence. Such work documents may include the following: - checklists - audit sampling plans - forms for recording information, such as supporting evidence, audit findings and records of meetings The use of checklists and forms should not restrict the extent of audit activities, which can change as a result of information collected during audit. Note: Guidance on preparing work documents is given in Clause B.4. Work documents, including records resulting from their use, should be retained at least until audit completion, or as specified in the audit plan. Retention of documents after audit completion is described in 6.6 of ISO 19011. Those documents involving confidential or proprietary information should be suitably safeguarded at all times by audit team members.

FOIA is Federal Occupational Injury Administration Federal Occupational Illness Administration Federal Occupational Injury/Illness Act Freedom of Information Act

*Freedom of Information Act allows the public to obtain information created or maintained by agencies of the federal government. Though there are restrictions on the type of information that can be distributed, if a member of the public can define the information that he/she wants, then the relevant agency is obligated to address the request. FOIA requests from agencies are frequently an excellent way to obtain internal memos, directives, and other information that would not normally be published, but may provide valuable information.

At one time it was considered that a plaintiff could not recover damages unless injury was due to physical contact. This principle has been modified or repudiated over the years to permit a plaintiff to collect damages for neurological or emotional disturbances that occurred without physical injury. This principle is known as: Fright without physical contact Privity without contact Strict liability Tort

*Fright without physical contact allow for damages in cases where there was emotional or similar damage and no physical injury was made

The temperature of a block of ice while melting remains constant. In the course of changing state, the block of ice is: Giving up energy Gaining energy but using energy to change state Converting energy to mass It neither gives up nor gains energy

*Gaining energy but using energy to change state In the process of melting, the block of ice gains heat energy. To illustrate, if a block of ice is heated, its temperature will reach 32degF. The temperature then remains constant and the ice begins to melt. As more heat is added, more ice will melt until it all turns to 32degF water. The energy gained by the ice is used to melt it.

Vapors of flammable and combustible liquid are: Generally heavier than air Lighter than air Normally liquid at room temperature and have molecular weights lower than those which are gases Unstable and unpredictable

*Generally heavier than air The vapors of flammable liquids are generally heavier than air. Examples are alcohol, naptha, gasoline, kerosene, and carbon disulfide. This is logical because gas or vapor density is proportional to molecular weight, and the compounds which are normally liquids at room temperature have higher molecular weights than those which are gases. Note that because vapors of flammable and combustible liquids are heavier than air, they tend to settle in lower areas and the trail of vapors can spread far from the liquid itself. If this vapor trail contacts a source of ignition, the resulting fire can FLASHBACK to the source of the vapors

Which of the following statements is not true? Generally, equipment installed in Class I locations need not be approved as explosion proof Since it is impractical to keep flammable gases outside of enclosures, arcing equipment must be installed in enclosures that are designed to withstand an explosion The equipment must not only be strong enough to withstand an internal explosion, but the enclosures must be designed to vent the resulting explosive gases Venting must ensure that the gases are cooled to a temperature below that of ignition temperature of the hazardous substance involved before being released into the hazardous atmosphere

*Generally, equipment installed in Class I locations need not be approved as explosion proof

An early form of preliminary hazard analysis was known as: Fault hazard analysis Primitive hazard analysis Gross hazard analysis Naked man analysis

*Gross hazard analysis now referred to as preliminary hazard analysis

What provides the best protection when transferring an extremely flammable liquid from a 55 gallon drum via a hand pump to a small metal safety can? Ground both containers Bond containers together Bond containers together and ground each to a separate low resistance ground Ground each container to a single low resistance ground and then bond them to each other

*Ground each container to a single low resistance ground and then bond them to each other Bonding is the process of connecting 2 or more conductive objects together by means of a conductor to minimize the potential electric difference between them. Grounding is the process of connecting the the conductive object to the ground, and is a specific type of bonding. A conductive object may also be grounded by bonding it to another conductive object that is already connected to the ground. Bonding minimizes potential differences between conductive objects. Grounding minimizes potential differences between conductive objects and the ground. The purpose of grounding or bonding in this question is to insure that there is no potential differences between the containers and earth ground; therefore, all objects must be connected to the same grounding point and bonded together. Alternatively, the same objective could be accomplished by insulating the drum and can from the earth ground and then bonding the drum to the can.

Guides and observers (ex. regulators or other interested parties) may accompany the audit team. Which of the following best describes the roles of these parties? Guides are appointed by the auditor Observers can assist the auditors with suggestions Guides ensure that rules concerning location safety and security procedures are known to audit team members Observers cannot be denied from taking part in audit activities

*Guides ensure that rules concerning location safety and security procedures are known to audit team members They should not influence or interfere with the conduct of the audit. If this cannot be assured, the audit team leader should have the right to deny observers from taking part in certain audit activities. For observers, any obligations in relation to health and safety, security and confidentiality should be managed between the audit client and the auditee. Guides, appointed by the auditee, should assist the audit team and act on the request of the audit team leader. Their responsibilities should include the following: - assisting the auditors in identifying individuals to participate in interviews and confirming timings; - arranging access to specific locations of the auditee; - ensuring that rules concerning location safety and security procedures are known and respected by the audit team members and observers The role of the guide may also include the following: - witnessing the audit on behalf of the auditee; - providing clarification or assisting in collecting information

The specific PHA (process hazard analysis) technique that brings together a multi-disciplinary team, usually five to seven people, to brainstorm and identify the consequences of deviations from design intent for various operations and uses specific guide words is called: Process hazard analysis Preliminary hazard analysis HAZOP analysis HAZWOPER analysis

*HAZOP analysis The hazard and operability study or analysis applies the use of specific guide words, such as NO, MORE, LESS, REVERSE, etc. which are applied to parameters like: Flow, Pressure, and Temperature to systematically identify hazards throughout the process

A process hazard analysis (PHA) will be conducted at your facility. The covered process for which this PHA is being conducted is actually being revalidated - the initial PHA for this process was performed about 3 years ago, and a HAZOP methodology was used then. The PHA leader has decided that a what-if/checklist methodology will be used for this PHA. You always thought that any PHA required performing a HAZOP. When you ask the facility's senior process safety engineer about this, what will you likely be told? HAZOP is the only accepted method for conducting any PHA HAZOP is only one of several methods (including what-if/checklist) that OSHA specifies for conducting PHAs A HAZOP is only required by OSHA to conduct the process's initial PHA. The what-if/checklist mehod may be used for revalidating/updating the process's PHA A what-if/checklist methodology should have been used for the first PHA and a HAZOP is only used for a covered process that processes one or more highly hazardous chemicals.

*HAZOP is only one of several methods (including what-if/checklist) that OSHA specifies for conducting PHAs Fault tree analysis, failure mode and effects analysis, what-if, checklist, and what-if/checklist are the specifically permitted methods. More info can be found in Guidelines for Hazard Evaluation Procedures, 2nd Edition published by the Center for Chemical Process Safety (a division of the American Institute of Chemical Engineers) 29 CFR 1910.119(e)(2)

In the late 1980s and early 1990s, which vaccine was identified as important for personnel at risk of exposure to BBPs? Tetanus HIV HBV HAV

*HBV was determined to be critical to offer to healthcare workers In 1991 it was made mandatory for workers at risk of exposure to BBPs in the US

Which of the following groups of hydrocarbons would have the greatest chance of not being flammable? Aliphatic hydrocarbons Aromatic hydrocarbons Halogenated hydrocarbons Ethers

*Halogenated hydrocarbons Hydrocarbons are compounds that contain atoms of carbon and hydrogen only. They are broadly classified into two types, that is; aliphatic and aromatic. Aliphatic hydrocarbons are subdivided into saturated and unsaturated compounds and include the alkanes: methane, ethane, propane and butane. Aromatic hydrocarbons are derivative of the parent compound benzene. Ethers are members of a class of organic compound in which an oxygen atom has bridged between 2 hydrocarbon groups. Aliphatic ethers are highly volatile and extremely flammable. Hydrocarbons that have been partially halogenated burn, but generally with much less ease than their nonhalogenated analogs. The fully halogenated derivatives such as carbon tetrachloride are non-combustible.

Which fire extinguishing agent contains halogenated hydrocarbons? Halon Carbon dioxide Dry powder Foam

*Halon = CFCs which react with stratospheric ozone

Back belts (braces) used for support: Are recommended by NIOSH and required by OSHA if back strain is possible Are considered a form of PPE for prevention of back injuries Have not been shown to lessen the risk of back injury among uninjured workers Must be provided at no cost to employees who request them

*Have not been shown to lessen the risk of back injury among uninjured workers The use of lifting belts for professional material handling does not seem to be an effective way of preventing overexertion injuries. When preparing to lift or lower a load, we instinctively develop intra-abdominal pressure within the trunk cavity. The pressure is believed to help support the curvature of the spine during the lifting or lowering effort. An external wrapping around the abdominal region might help to maintain the internal pressure because it makes the walls of the pressure column stiffer. A large number of studies have been performed, summarized, and reviewed by McGill (1999)m Lavender et al (1998), and Thoumier et al (1998). Their conclusions neither summarily support nor condemn the wearing of support belts in industrial jobs.

Process variations occur because of equipment failures, human errors, and process upsets such as localized chemical reactions. The analysis methodology that implements a systematic way to examine how process variations affect a system is called? Hazard and Operability (HAZOP) Checklist Fault Tree Analysis (FTA) Failure Mode and Effects Analysis (FMEA)

*Hazard and Operability (HAZOP) The Hazard and Operability (HAZOP) analysis methodology is a systematic way to examine how process variation affect a system. Process variations occur as a result of equipment failures, human errors, and process upsets such as localized chemical reactions. The technique can be used for systems with continuous processes as well as batch processes. The use of HAZOP analysis methodology requires detailed information about the design and operation of the process. The HAZOP methodology is most effective during the design phase of a process or for existing processes. In the HAZOP analysis, a hazard evaluation team composed of experts from different areas systematically examines every part of the process to discover how processes design deviations can occur. The hazard evaluation team leader systematically guides the team through the process design, using a fixed set of guide words. These guide words are applied at crucial points or nodes of the process. The guide words include no, more, less, as well as, part of, reverse, and other than. They are combined with a condition, such as flow or pressure, to define the deviation. For example, "What is the effect of low flow on the process?" Typical deviations include leaks or ruptures, loss of containment, ignition sources, and chemical reactions. The HAZOP analysis should identify hazards and operating problems, and enable the HAZOP team to recommend design or procedural changes that will improve the safety of the process. The results of the HAZOP analysis are documented in a tabular format with a separate table for each segment of the process under study. Ex. Chemical and petroleum industries; Team of experts

Which of the following key label elements are standardized under the GHS? Product identifier, supplier identifier, chemical identity Hazard pictograms, signal words, hazard statements Precautionary information, product identifier, hazard statements Signal words, chemical identity, hazard pictogram

*Hazard pictograms, signal words, hazard statements The GHS Working Group identified about 35 different types of information currently required on labels by different systems. To harmonize, key information elements needed to be identified. Additional harmonization may occur on other elements in time, in particular for precautionary statements. The elements are identified below (*STANDARDIZED): Product Identifier Supplier Identifier Chemical Identity *Hazard Pictograms *Signal Words *Hazard Statements Precautionary Information

In responding to a spill of hazardous materials, which of the following is not a good source of information for prompt hazard recognition? MSDSs Hazardous waste manifest Manufacturer label Symbolic labels

*Hazardous waste manifest does not contain hazard information

The most serious form of heat disease is considered to be Heat stress Heat syncope Prickley heat Heat stroke

*Heat stroke Heat stroke is life threatening and therefore the most serious. The body temperature rises to dangerous levels causing potentially irreversible damage and possibly death

After establishing the required management systems, to become formally registered as compliant with the ISO-9000 or ISO-14000 standards, a company must: Certify in writing to the International Organization for Standardization (ISO) that the company complies with the relevant standards Hire an ISO-certified third-party registrar to perform an external audit of the company's facilities at which point the third-party registrar will certify to the ISO that the company complies with the relevant standards (if the company is compliant) Hire an ISO-trained auditor to perform an external audit of the company's facilities at which point the external auditor will certify that the company complies with the relevant standards (if the company is compliant) Simply maintain compliance with the relevant ISO standards and submit an annual certification fee to ISO

*Hire an ISO-certified third-party registrar to perform an external audit of the company's facilities at which point the third-party registrar will certify to the ISO that the company complies with the relevant standards (if the company is compliant) A registrar formally certified by ISO as a registrar must be retrained for the audit and subsequent certification to ISO that the company meets ISO requirements

A clause in a contract in which one party agrees to assume liabilities, losses, or expenses of another is known as a: Deductible clause Hold harmless agreement Exemption Assumption of risk clause

*Hold harmless agreement

An agreement or contract in which one party agrees to hold the other free from the responsibility for any liability or damage that might arise out of the transaction involved is called a Strict liability Hold harmless agreement Negligence Exclusive remedy

*Hold harmless agreement A hold harmless (indemnity) agreement is used between two parties to establish that the indemnitee is protected from any unforeseen liabilities, losses, claims or damages during their involvement in an activity. A hold harmless agreement is developed to prevent law suits by assigning liability in a contract. Hold harmless means that if there is a problem and a suit later, one party shields or "holds harmless" the other. A hold harmless clause is a statement in a legal contract stating that an individual or organization is not liable for any injuries or damages caused to the individual signing the contract. An individual may be asked to sign a hold harmless agreement when undertaking an activity that involves risk for which the enabling entity does not want to be legally or financially responsible.

The least likely term which describes designing the job to fit the worker is: human factors human engineering ergonomics human systems

*Human systems Ergonomics, human factors, human engineering, biomechanics and engineering anthropometry are terms common to the objective leading to designing a work station, display, or job, to fit the worker and avoid unnecessary environmental stresses. The desired results of this design is a decrease of injury/illness and an increase in productivity.

When a fuel and oxidizer reacts so rapidly on being mixed at room temperature that combustion starts immediately without an outside ignition source, it is known as: Hypergolic Explosive Adiabatic Flammable

*Hypergolic a hypergolic reaction is a reaction where heat initially emitted will initiate combustion with no other ignition source required

What is the primary function of a loss control system? Assess risk, establish effective risk control measures, and elimination of risk Establish effective risk control measures for hazardous conditions, establish effective control measures, elimination of risk Identify hazardous conditions, assess their risks, and establish effective risk control measures Assure compliance with applicable regulatory requirements and eliminate the residual risk

*Identify hazardous conditions, assess their risks, and establish effective risk control measures As described in Assurance Technologies, a loss control system must be able to identify the hazardous conditions as well as understand the real risks associated with those hazardous conditions. A loss control system is incomplete if it solely identifies hazardous conditions and does not take action to understand the risks. Effective risk control measures are relative to the risks associated with the hazardous conditions. Cannot eliminate risk

Implied warranty involves: Statement Implication Negligence Tort

*Implication An implied warranty revolves around the implications of a manufacturer or dealer that a product is suitable

Workplace Electrical Safety Standard are the most often utilized in the industry to perform arc flash hazard analysis. These calculations are based upon: Potential Energy Incident Energy Hazardous Energy Absorbed Energy

*Incident Energy NFPA 70E Standard The arc flash boundary for systems 50 V and greater shall be the distance at which the incident energy equals 5 J/cm^2 (1.2 cal/cm^2). Determining accurate onset to second degree burn energy and its significance in computing the arc flash boundary is focused on the prevention of injury to the skin of a human who might be exposed to an arc-flash. Different formulas have been proposed to calculate incident energy at an assumed working distance, and the arc flash boundary in order to determine arc rated PPE for Qualified Electrical Workers. The Institute of Electrical and Electronics Engineers (IEEE) Standard P1584 Guide for Performing Arc-Flash Hazard Calculations [1584 IEEE Guide for Performing Arc-Flash Hazard Calculations. IEEE Industry Applications Society. September 2002] and formulas provided in Annex D of NFPA 70E CSA Z462 [CSA Z462 Workplace electrical safety Standards. 2012.] Workplace Electrical Safety Standard are the most often utilized in the industry to perform arc flash hazard analysis. The formulas are based on incident energy testing performed and calculations conducted for selected range of prospective fault currents, system voltages, physical configurations, etc. The FPB is the distance at which incident energy is 1.2 cal/cm^2, which is the amount of heat needed to cause second-degree burns. Limited Approach Boundary: Entered only by qualified persons or unqualified persons that have been advised and are escorted by a qualified person Restricted Approach Boundary: Entered only by qualified persons required to use shock protection techniques and PPE Flash Protection Boundary: Linear distance to prevent any more than 2nd degree burns from a potential arc-flash (typically 4 ft) The purpose of incident energy calculations is to determine the appropriate PPE that will limit the possible thermal energy exposure to the critical body parts, such as face and chest areas. Usually, the calculations give the heat-exposure in calories/cm^2 or Joules/cm^2. Once you know the heat exposure level, you can choose the protective clothing to best protect your employees. NFPA 70E Standard

Which of the following best describes Carpal Tunnel Syndrome? Elbow and shoulder swelling and inflammation Inflammation of ligaments in the wrist Raynaud's Syndrome of hand and wrist Numbness of the lower legs

*Inflammation of ligaments in the wrist According to NIOSH, CTS occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist. The median nerve controls sensations to the palm side of the thumb and fingers (although not the little finger), as well as impulses to some small muscles in the hand that allow the fingers and thumb to move. The carpal tunnel - a narrow, rigid passageway of ligament and bones at the base of the hand - houses the median nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the median nerve to be compressed. The result may be pain, numbness, or weakness in the hand and wrist, radiating up the arm. This injury is common among repetitive motion workers. The median nerve is compressed resulting in numbness, tingling and sometimes pain in the fingers and wrist. Symptoms usually start gradually, with frequent burning, tingling, or itching numbness in the palm of the land and the fingers, especially the thumb and the index and middle fingers. Some carpal tunnel sufferers say their fingers feel useless and swollen, even though little or no swelling is apparent. The symptoms often first appear in one or both hands during the night, since many people sleep with flexed wrists. A person with CTS may wake up feeling the need to "shake out" the hand or wrist. As symptoms worsen, people might feel tingling during the day. Decreased grip strength may make it difficult to form a fist, grasp small objects, or perform other manual tasks. In chronic and/or untreated cases, the muscles at the base of the thumb may waste away. Some people are unable to tell between hot and cold by touch.

Auditing is characterized by reliance on many principles. Adherence to these principles is a prerequisite for providing audit conclusions that are relevant and sufficient and for enabling auditors, working independently from one another, to reach similar conclusions in similar circumstances. Which of the following are included in these principles? Integrity, confidentiality, due professional care. Confidentiality, conformity, liability. Fair representation, subjective observation, performance in a partial manner. Evidence based, interdependence, biased.

*Integrity, confidentiality, due professional care. Te guidance given in Clauses 5 to 7 of ISO 19011 is based on the 6 principles outlined below: 1. Integrity: The foundation of professionalism. Auditors and the person managing an audit program should: - perform their work with honesty, diligence, and responsibility; - observe and comply with any applicable legal requirements; - demonstrate their competence while performing their work; - perform their work in an impartial manner, ex. remain fair and unbiased in all their dealings; be sensitive to any influences that may be exerted on their judgement while carrying out an audit 2. Fair Presentation: the obligation to report truthfully and accurately. Audit findings, audit conclusions and audit reports should reflect truthfully and accurately the audit activities. Significant obstacles encountered during the audit and unresolved diverging opinions between the audit team and the auditee should be reported. The communication should be truthful, accurate, objective, timely, clear and complete. 3. Due Professional Care: the application of diligence and judgement in auditing. Auditors should exercise due care in accordance with the importance of the task they perform, and the confidence placed in them by the audit client and other interested parties. An important factor in carrying out their work with due professional care is having the ability to make reasoned judgments in all audit situations. 4. Confidentiality: security of information. Auditors should exercise discretion in the use and protection of information acquired in the course of their duties. Audit information should not be used inappropriately for personal gain by the auditor or the audit client, or in a manner detrimental to the legitimate interests of the auditee. This concept includes the proper handling of sensitive or confidential information. 5. Independence: the basis for the impartiality for the audit and objectivity of the audit conclusions. Auditors should be independent of the activity being audited wherever practicable, and should in all cases act in a manner that is free from bias and conflict of interest. For internal audits, auditors should be independent from the operating managers of the function being audited. Auditors should maintain objectivity throughout the audit process to ensure that the audit findings and conclusions are based only on the audit evidence. For small organizations, it may not be possible for internal auditors to be fully independent of the activity being audited, but every effort should be made to remove bias and encourage objectivity. 6. Evidence-based approach: the rational method for reaching reliable and reproducible audit conclusions in a systematic audit process. Audit evidence should be verifiable. It will in general be based on samples of the information available, since an audit is conducted during a finite period of time and with finite resources. An appropriate use of sampling should be applied, since this is closely related to the confidence that can be placed in the audit.

There are a number of management standards published by ISO. ISO is an acronym for:

*International Organization for Standardization non-governmental organization

What functions do corporate safety groups normally not perform? Safety policy development Safety procedure development Corporate safety manual Investigate plant accidents

*Investigate plant accidents

ANSI: Serves as the Head of ISO and chairs the IEC Is not involved in international standards, as it is a US based organization Provides oversight for all ISO standards development Is the US representative to ISO and IEC

*Is the US representative to ISO and IEC ANSI is the US representative of the two major non-treaty international standards organizations, the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC) [via the US National Committee USNC]

Why is it a good idea to have a formal safety and health statement of policy? Safety and health should be of primary concern to everybody It is the starting point for all activities in the safety and health program It expresses management's attitude toward safety and health It publicizes the safety and health function

*It expresses management's attitude toward safety and health The formal safety and health statement of policy is an endorsement of top management's commitment and support. It is management's expression of the direction to be followed.

A procedure to make a job safe by identifying hazards in each step of the job and developing measures to counteract those hazards is: Time and motion Fault tree Job safety analysis Probabilistic risk assessment

*Job safety analysis

Manual materials handling tasks can be designed to avoid injuries. Modifications to the task could include all of the following EXCEPT Keep loads as close to the body as possible during lifting Keep loads off the floor by using platforms or stands Keep all repetitive lifts between knee and waist height Avoid twisting, stretching, or leaning with the load

*Keep all repetitive lifts between knee and waist height Repetitive lifts should be kept between knuckle and shoulder height to reduce bending and reaching for the load. Keeping the loads close to the body, off the floor, and avoiding twisting, stretching, or leaning will help avoid the musculoskeletal, crushing, or falling injuries frequently caused by manual materials handling.

Manipulative tasks are highly repetitive and can cause an overload on muscles and joints. The following are good design guidelines for manipulative arm and hand work EXCEPT Keep movements of arms and hands well within the full range of motion of body joints Don't force body joints to the extreme of their range of motion Keep elbows at 60 degrees and at or above mid-torso height Keep wrists straight

*Keep elbows at 60 degrees and at or above mid-torso height Elbows should be kept at 90 degrees and below mid-torso height for maximum comfort and least strain on the muscles and tendons. Keeping body joints within the range of motion and away from extremes reduces potential for strains and sprains. Straight wrists will prevent repetitive motion injuries.

What is the best design for continuous input with prevision for operator control? Toggle switch Knob Limit switch Push button

*Knob

The human body is More capable of coping with heat loss than heat gain Less capable of coping with heat loss than heat gain Equally capable of coping with heat loss or heat gain Unaffected by environments with potential of heat loss or gain

*Less capable of coping with heat loss than heat gain Warm-blooded The human body is designed to work optimally at a temperature of 98.6degF +/- 1.8degF. Exposure to cold temps, air temps less than 61degF, can reduce manual dexterity. While adaptive mechanisms (ex. sweating and acclimation) are crucial during heat stress exposures, the physiological adaptations to cold stress have less dramatic effects. The first physiological response to cold stress is to conserve body heat by reducing blood circulation through the skin, effectively making the skin an insulating layer. The second physiological response is boosting the body's metabolism though shivering, a sign of significant cold stress.

Which of the following is not considered a phase of Emergency Management? Response Recovery Mitigation Litigation

*Litigation The coordinated response to and recovery from an event is the main stay of Emergency Management. Preparedness is planning how to respond in case an emergency or disaster occurs and working to increase the resources that are available to respond effectively Response involves the effective and efficient application of assets and activities to resolve the immediate impacts of an event. In the case of a planned event, response activities include the application of sufficient resources to ensure that the event occurs without undue or unexpected undesirable outcomes Recovery activities occur until all community systems return to normal or nearly normal conditions. This includes both short-term and long-term recovery actions Mitigation refers to those actions and activities taken to reduce or eliminate the chance of occurrence or the effects of a disaster

In evaluating software related errors, most errors occur during: Data handling User interface Logic development Computational

*Logic development 21.29% Input/output errors account for 14.74% Computational errors account for 8.34% User interface errors account for 7.7% Routine-to-routine interface errors account for 5.62%

Any action which reduces losses incurred, by definition, is Loss control Loss transfer Risk management Loss reduction

*Loss reduction Loss reduction means any action which reduces the losses incurred. The reduction may be by decrease of they physical destruction (as by reducing the amount of material burned or the number or persons injured) or by reducing the operational loss from a given amount of destruction (as having standby equipment or more effective medical care for the injured). It includes the concepts of loss prevention and control as well as the concept of risk avoidance - the refusal to accept a given risk. Planning actions are not generally considered part of loss reduction. The four steps required in an effective loss control program are problem identification, selection of corrective measures, implementation and feedback and control. There are 5 stages in risk analysis and management: identification, estimation, evaluation, response and monitoring. Ex. Sprinkler systems, seat belts

Which is not correct concerning MSDSs? Title III requires MSDSs to be submitted to the State Emergency Response Center Worker's Right-to-Know requires employers to make MSDSs available to employees Worker's Right-to-Know requires chemical manufacturers to develop MSDSs MSDSs provide accurate and appropriate data all of the time

*MSDSs provide accurate and appropriate data all of the time may be in error, out of date, etc. the data should be cross-checked when possible

Disorders that affect the muscles, nerves, blood vessels, ligaments and tendons are called: Chronic wasting disease (CWD) Musculoskeletal Disorders (MSDs) Cumulative trauma disorders (CTDs) Soft tissue diseases (STDs)

*MSDs MSDs affect the muscles, nerves, blood vessels, ligaments and tendons. Workers in many different industries and occupations can be exposed to risk factors at work, such as lifting heavy items, bending, reaching overhead, pushing and pulling heavy loads, working in awkward body postures and performing the same or similar tasks repetitively. Exposure to these known risk factors for MSDs increases a worker's risk of injury. MSDs are very difficult to define within traditional disease classifications. These disorders have received many names, such as: - Repetitive motion injuries - Repetitive strain injuries - Cumulative trauma disorders - Occupational cervicobrachial disorders - Overuse syndrome - Regional musculoskeletal disorders - Soft tissue disorders Most of the names do not accurately describe the disorders. For example, the term "repetitive strain injuries" suggests that repetition causes these disorders, but awkward postures also contribute. These terms are used synonymously, however, MSD term is used in current literature. Work-related MSDs can be prevented. Ergonomics - fitting a job to a person - helps lessen muscle fatigue, increases productivity and reduces the number and severity of work-related MSDs. Bureau of Labor Statistics (BLS) defines MSDs to include cases where the nature of the injury or illness is pinched nerve; herniated disc; meniscus tear; sprains, strains, tears; hernia (traumatic and nontraumatic); pain, swelling, and numbness; carpal or tarsal tunnel syndrome; Raynaud's syndrome or phenomenon; MS system and connective tissue diseases and disorders, when the event or exposure leading to the injury or illness is overexertion and bodily reaction, unspecified; overexertion involving outside sources; repetitive motion involving microtasks; other and multiple exertions or bodily reactions; and rubbed, abraded, or jarred by vibration. The risk of MSD injury depends on work positions and postures, how often the task is performed, the level of required effort and how long the task lasts. To reduce the change of injury, work tasks should be designed to limit exposure to ergonomic risk factors. Engineering controls are the most desirable, where possible. Administrative or work practice controls may be appropriate in some cases where engineering controls cannot be implemented or when different procedures are needed after implementation of the new engineering controls. PP solutions have only limited effectiveness when dealing with ergonomic hazards.

Which of these metals is combustible? Nickel Magnesium Molyndenum Iron

*Magnesium Other examples of combustible metals: Titanium Zirconium Sodium Potassium Class D Fires involve these metals

Of the following, the least likely reason to perform a health and safety audit is Determine if codes, laws and regulations are being complied with Assess the over-all program and its conformance to accepted safety and health practices Determine if company policies, procedure, and standards are being met Make sure company is prepared for an OSHA inspection

*Make sure company is prepared for an OSHA inspection The purpose of an effective health and safety audit is to conduct a systematic, objective analysis of a company's health and safety practices that is directed toward well defined goals, namely; regulatory compliance, accident-injury/illness risk control, program activities, record analysis and company policies. Following the audit, a report is prepared in which a written assessment is made along with recommendations to improve health and safety management of any significant risks that were identified

Which of the following is a key objective for the staff safety professional? Making every effort to ensure that management retains responsibility for safety Making every effort to be personally acquainted with line employees Making every effort to retain direct responsibility for the corporate safety function Making every effort to directly investigate all accidents and near misses

*Making every effort to ensure that management retains responsibility for safety staff safety professionals should ensure that the fundamental principles of loss control are followed by the company. In this case, the fundamental loss control principle of fixing accountability for line safety performance is facilitated by answer A

The theory on human motivation which declares that workers are uninterested in and unmotivated toward work; to motivate them to work, a system of rewards and punishments is necessary, applies to: McGregor's Theory Y McGregor's Theory X Herzberg's Job-enrichment Theory Likert's Theory

*McGregor's Theory X In an attempt to analyze how management personnel view human motivation, McGregor evolved the notion there are 2 basic ways in which management can view the worker: Theory X - assumes the worker is essentially uninterested and unmotivated to work Theory Y - assumes the worker is basically interested and motivated to work

Which of the following pass through the carpal tunnel? Medial nerve and radial artery Ulnar nerve and ulnar artery Ulnar nerve and flexor tendons Median nerve and flexor tendons

*Median nerve and flexor tendons The carpal tunnel or carpal canal is the passageway on the palmar side of the wrist that connects the forearm to the middle compartment of the palm. The tunnel consists of bones and connective tissue. Several tendons and the median nerve pass through it.

*Naked man this technique appears to be primarily a brainstorming approach designed to detect gaps and areas of overlapping protection to aid in identifying the most cost-effect control measures

As a safety professional, you are concerned with professional liability. Your company has insurance for the errors and omissions of its employees. Does this insurance actually cover you for your errors and omissions made as an employee of this company? Yes, completely Yes, partially No Safety professionals are not subject to such liability

*No The insurance policy owned by your company protects the company specifically, and does not cover you at all. If your company is sued as a result of errors and omissions of your work, your company and your company's insurance company are strictly looking out after their own best interests. It is likely that the company's insurance will be sufficient to resolve any claims; however, if the company settles a case for more than the insurance is required to pay, a plaintiff could sue you personally to recover additional damages

An electrician assures you that the standard duplex wall receptacle is wired correctly. She shows you on her multimeter (properly set for AC voltage) that the voltage across the brass-colored terminal and the terminal labeled with a "W" is 115 V. Do you agree with her assurance that the receptacle is wired correctly? Yes No. Ask her to test the voltage across the brass-colored terminal and the green-colored terminal. If it reads 115 V, then agree with her assurance. No. Ask her to test the voltage across the "W"-labeled terminal and the green-colored terminal. If it reads 115 V, then agree with her assurance No. Ask her to test the voltage across the "W"-labeled terminal and the green-colored terminal. If it reads 0 V, then agree with her assurance.

*No. Ask her to test the voltage across the "W"-labeled terminal and the green-colored terminal. If it reads 0 V, then trust her assurance. There should be no voltage across the grounded conductor ("W"-labeled terminal) and the ground wire (green-colored terminal). If there is voltage, then the white wire and the black wire (hot wire) are reversed

The best example of a proactive approach is which of the following? Analysis of past injury/illness to identify trends Use of a medical history questionnaire to identify workers with preexisting conditions Implement a strength testing protocol to select workers based on physical demands of the job Observations and use of employee symptom surveys to identify problem jobs and tasks

*Observations and use of employee symptom surveys to identify problem jobs and tasks Both reactive and proactive worksite analysis approaches are used when identifying existing or potential ergonomic hazards and conditions. Reactive worksite analysis by definition means analysis of past incidences while proactive means identification of problem jobs and tasks before injury or illness has occurred. Reviewing past injury records is an example of a passive or reactive approach as you are analyzing incidences which have already occurred. Observations and symptom surveys are used to identify workers who might be in pain but who have not yet reported an injury. Ergonomics interventions can be implemented before an injury occurs. Medical histories and strength testing are often used to screen workers who might be at risk of injury but there is little data to show these techniques are effective.

Speech interference levels can be determined which one of the following instruments? Sound level meters Impact noise analyzers Octave band analyzers Noise dosimeters

*Of 'customer' requests for a management standard that addresses occupational health and safety BSI has stated its intention to withdraw the standard if an Internal Standard is published covering the subject matter. Occupational Health and Safety Management Systems standard 18001 is produced by BSI. BSI led the development of 18001 as a health and safety management system standard that is compatible with ISO 9001 and ISO 14001.

CRM is a technique to properly use all of the operations professionals on a team to reliably meet mission objectives. It is derived from efforts to make aircraft cockpit crews more team-oriented versus the highly authoritarian environments in which cockpit crews formally found themselves. Of the following, which dynamic human environment is the best candidate for applying the principles of CRM? Offsite incident command staff-onsite incident command staff during an emergency Trainer-trainees during a class Employee-supervisor during a performance appraisal Passengers-flight attendants during a flight

*Offsite incident command staff-onsite incident command staff during an emergency Incident command could greatly benefit from applying the principles of CRM. In this environment, all of the incident command professionals have the same goal; however, culture, work habits, and other non-relevant issues can cloud the efficient exchange of information to meet the mission objectives

Which of the following is the BEST method for conducting interviews associated with an incident investigation? One interviewer and one witness in a room with audio recording Three interviewers and one witness in a room One interviewer and three witnesses in a room One interviewer and one witness in a room

*One interviewer and one witness in a room Audio and video recording should always be avoided as this will typically make the witness nervous and less likely to be fully open. Having three interviewers is intimidating to the witness. Interviewing multiple witnesses at the same time should be avoided since frequently, a dominant person will speak for the group. The other witnesses with information will reason with themselves that other witnesses in the room have better information - particularly if the information is contradictory

Building fire safety is achieved by all of the following except: Separating ignitors from ignitable materials Managing the impact of a fire through building design Take measurements to control products of combustion Organizing a fire brigade

*Organizing a fire brigade Building fire safety may be achieved either by fire (ignition) prevention or, if a fire does occur, by managing its impact through building design. Fire prevention is accomplished by separating ignitiors from ignitable materials. The products of combustion that must be considered by the building designer are categorized as thermal (flame and heat) and nonthermal (smoke and gases).

During a semi-annual inspection, what is the best chain inspection method? Check links with a caliper and compare at least 10 links Check for cracks in end links Compare twist on end sections Perform a detailed link-by-link inspection of the entire chain

*Perform a detailed link-by-link inspection of the entire chain Chain inspections should be done visually in an attempt to detect any elongation or other defect. This is best accomplished with a link-by-link inspection. Overall measurements or caliper readings of a section are often misleading because not all links will be affected or damaged.

The purpose of this analysis is to provide a technique to model systems components at a wide range of abstract levels. This analysis can be defined in purely mathematical terms, and is in such form that the analysis can be automated. Fault tree analysis Petri network analysis Digraph analysis Event tree analysis

To reduce eye strain while transporting data from a paper to a computer, it is best to: Place the paper next to the computer screen Place the paper above the computer screen Place paper on the desk Place the paper below the computer screen

*Place the paper next to the computer screen The name for eye problems caused by computer use is computer vision syndrome (CVS). CVS is not one specific eye problem. Instead, the term encompasses a whole range of eyestrain and pain experienced by computer users. Working at a computer requires that the eyes continually focus, move back and forth, and align with what you are seeing. Working at a computer gets even more difficult as you get older. That's because the lens of your eye becomes less flexible. The ability to focus on near and far objects starts to diminish after about age 40 - a condition called presbyopia. To reduce eyestrain, papers should be placed next to the computer screen at eye level

In workers compensation cases for hearing loss the term high fence is often used. High fence also varies by state. What is the meaning of the term high fence? Point the worker must reach Point of 100% hearing impairment Point of 0% hearing impairment Point of 50% hearing impairment

*Point of 100% hearing impairment = hearing loss Varies by state law

What is one disadvantage of having an internal safety program evaluation group? Evaluation staff knows plant workers Less obtrusive audit Potentially less objective Harder to work with

*Potentially less objective One main drawback of an internal safety program audit group is the fact that they are less likely to be totally objective due to personal knowledge

The boom indicator on a mobile crane: Provides the angle of the boom Shows the safe load with the boom at any angle Indicates load capacity Signals when the crane is out of balance

*Provides the angle of the boom A boom indicator is a device that shows the angle of the boom. The boom angle is used in conjunction with the crane load chart to determine safe loads. Modern load measuring systems for cranes allow for real-time direct reading of actual crane load and can provide output warnings indicating that the rated capacity is approaching. Such devices can even be integrated with the crane controls to stop the crane operation.

In manual materials handling, methods for eliminating the need to bend include all of the following EXCEPT Using lift tables, work dispensers, and other mechanical aids Raising the work level to an appropriate height Providing materials and tools in front of the worker Lowering the worker

*Providing materials and tools in front of the worker Although providing materials and tools in front of the worker helps to prevent twisting motions, to avoid bending motions the work needs to be at the proper height. This can be accomplished through mechanical means (lift tables), raising he work level, or lowering the worker to the level of the work.

It is possible to reduce incidents involving human error by: Carefully screening job applicants Furnishing workers with PPE Providing training and education to workers and line supervisors Improving workplace conditions

*Providing training and education to workers and line supervisors It is generally agreed that the largest majority of incidents leading to an accident are attributed to unsafe acts rather than unsafe conditions. Although general estimates of many of the mental and emotional states that cause accidents (like indifference, resentment of authority, disregard of danger, undue haste, anger, impatience, boredom) are not reliable, there is consensus that effective training and education will prevent many of the human errors (unsafe acts) that arise from mental and emotional states

The term defines the following: the relationship between the plaintiff's injuries and the defendant's failure to exercise a legal duty, such as reasonable care Privity Proximate cause Foreseeability Care

*Proximate cause defines the relationship between the injury and the responsible party (because they did not exercise reasonable level of care or other reasonable standard).

Which disease is characterized by white fingers and numbness? Siderosis Raynaud's Syndrome Lead poisoning Tetanus

*Raynaud's Syndrome A combination of cold and vibration often causes Raynaud's phenomenon or traumatic vasospastic disease. This is a condition, usually of the fingers and hands, characterized by pallor caused by a greatly diminished blood supply resulting from spasm of the blood vessel walls. In addition to white fingers, the victim may also experience numbness of the affected area. The disease is most prevalent among those who work with vibrating machinery in the cold. Typical occupations are chain saw operators, jackhammer operators, tamping tool operators, etc.

Barrier creams: Neutralize potential irritants Reduce contact of the irritants with skin Are preferred to gloves in most cases Are not effective

*Reduce contact of the irritants with skin provide a protective barrier between the skin and the chemical. They are not neutralizing agents for chemicals

The preferred course for a company's management to meet the consequent risk of product liability is: Regulation of risk through careful statement of conditions of sale and delivery Transfer of risk through the underwriting of product liability insurance Reduction of risk through the introduction of effective quality assurance Acceptance of risk through passivity

*Reduction of risk through the introduction of effective quality assurance The management of a company must consider what ways or combinations of ways are available to meet the consequent risk of product liability. Of the four fundamentally different risk alternatives that the company's management can take, the reduction of the existing risk through introduction or improvement of quality assurance will give better conditions for regulation and transfer of risk

The term psychophysical is most related to: Isotonic dynamic muscle force development Relationship between sensations and physical stimuli The study of how our emotions impact our health Study of biological indicators such as heart rate and energy expenditure

*Relationship between sensations and physical stimuli Psychophysical methods are used to study acceptable weights for manual lifting. The worker can adjust the weight of the lift to match his or her own personal feelings of fatigue or perception of what can be sustained for several hours.

Dealing with the uncertainty and unpredictability of personal injury, property or damage loss, business interruption and liability is identified with: Casualty insurance Loss prevention Risk management Loss control management

*Risk management risk management is the decision-making process whose objective is to identify the proper mix of loss control, risk retention and risk transfer that the organization should use in dealing with its risks of personal injury, property loss or damage and damage and liability including the expense and revenue losses associated with these exposures

The purpose of this analysis is to identify casual factors relating to an accident or near-miss. The technique goes beyond the direct causes to identify the fundamental reasons for the event Management oversight and risk tree Root cause analysis Event tree analysis Fault tree analysis

*Root cause analysis considers "why" statements to determine root cause categories. The objective is to find one root cause that is the fundamental reason behind a set of related shortcomings

Barrier analysis is utilized within the following accident investigation techniques? Sequential time plotting Critical incident technique Root cause analysis and management oversight and risk tree Event analysis

*Root cause analysis and management oversight risk tree Root cause analysis utilizes Barrier Analysis as one technique to help develop information concerning event flow. Management Oversight and Risk Tree also applies Barrier Analysis when evaluating energy flow.

An analytical technique called 5-Whys is used to identify: Root causes of incidents Human behavior characteristics Behavior-based safety rules Human errors

*Root causes of incidents 5-Whys is a qualitative analytical technique to identify the root causes of an incident sequence. Once the causal factors (discreet human errors and equipment malfunctions that led to the loss of an event) are known, a 5-whys analysis can be performed on each causal factor to determine "why" the causal factor was allowed to exist

Under ICS, the Command Staff positions include: Safety Officer, Public Information Officer, and Liaison Officer Liaison Officer, Operations Section Chief, and Finance and Administration Section Chief Public Information Officer, Chief Executive Officer, and Safety Officer Logistics Section Chief, Safety Officer, and the Contracting Officer

*Safety Officer, Public Information Officer, and Liaison Officer ICS is organized into 3 components: Incident Command Command Staff General Staff Incident Command can be comprised either of a single Incident Commander or a Unified Command. The Command Staff (CS) members perform incident-wide tasks and report directly to the IC. The three most common CS positions include: Safety Officer - responsible for the safe operations of all tasks performed on-site. The safety office has the essential authority to terminate any operations deemed to be unsafe, and even to override the authority of the IC to do so Public Information Officer - The PIO is responsible for passing information regarding the incident to the public and to the media. Traditionally the PIO was responsible for press releases and public warning statements issues through the media. In recent years with the huge explosion of social media the PIO position has expanded greatly Liaison Officer - this position is responsible for interacting and coordinating with other response entities not represented in the incident to provide their input on legal issues and resource availability

What hand tool is most often misused? Wrench Pliers Screwdriver Hammer

*Screwdriver The 2 most common hazards associated with the use of hand tools are misuse and improper maintenance. Misuse occurs when a hand tool is used for something other than its intended purpose. Improper maintenance allows hand tools to deteriorate into an unsafe condition. According to the NSC, the screwdriver is perhaps the most misused and abused tool in the workplace. Misuse can compromise the integrity of the tool by breaking the handle, bending the shaft or dulling the tip, making workers susceptible to hand injury when the tool is used correctly. To prevent injury and keep screwdrivers in shape, the NSC recommends: - Do not use a screwdriver as a punch, wedge, pinch bar or pry - Keep the tip clean and sharp to permit a solid grip on the tip of the screw - Keep the handle of the screwdriver clean and intact to allow for a solid grip - Never hold the piece you are working on in your hand. Always lay it on a workbench or place it in a vice - Carry screwdrivers in toolboxes or work belts - never in your pocket. In wood and sheet metal, make a pilot hole for the screw. - Never use a screwdriver during electrical work unless it is properly insulated

You are a practicing ASP certificate holder. You submit a safety plan you have reviewed to a client. A year later, you notice that the client has made some changes to the safety plan (without your knowledge) and has removed the cover sheet from the original plan you approved and stapled it into the modified plan. What should you do? Hire an attorney and sue the client Remove the cover page from the safety plan, and complain to the client Send a formal letter to the client explaining your concern and your expectation that the modified safety plan should again be reviewed by a safety professional and that the cover page with your signature on it should be destroyed Ignore the issue assuming that the changes were insignificant to warrant further discussion

*Send a formal letter to the client explaining your concern and your expectation that the modified safety plan should again be reviewed by a safety professional and that the cover page with your signature on it should be destroyed It is likely that the client made what he or she perceived were minor changes to the safety plan, and it is also likely that you had failed to tell the client what changes were allowed (without further review) and what changes would require subsequent review. A polite letter apologizing for any oversights on your part while clearly identifying the problem and suitable resolutions is the best way to handle this conflict

Which of the following is not true? Equipment with wiring approved as intrinsically safe is acceptable in any hazardous (classified) location for which it is designated All interconnections between circuits must be evaluated to be sure that an unexpected source of ignition is not introduced through other non-intrinsically safe equipment Intrinsically safe equipment is not capable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of specific flammable or combustible atmospheric mixtures in their most easily ignitable concentrations Separation of intrinsically safe and non-intrinsically safe wiring is not necessary to ensure that the circuits in hazardous (classified) locations remain safe

In 1931, Heinrich significantly changed the thinking of safety professionals. He: Shifted the emphasis from conditions to actions Suggested the use of JSA to analyze accidents Applied forensic science to accident analysis Proposed monetary penalties for accidents

*Shifted the emphasis from conditions to actions In the early 1900s, employers concentrated mor eon inspection of the workplace. Heinrich suggested that more emphasis be placed on the actions of employees.

A process hazard analysis of potentially catastrophic processes: Should be done only if applicable under the OSHA Process Safety Standard Should be performed only by licensed professionals Should be done whether or not the process is applicable, under the OSHA Process Safety Standard A & B

*Should be done whether or not the process is applicable, under the OSHA Process Safety Standard A process hazard analysis should be performed if there is knowledge that potential exists for a catastrophic release from a process, whether or not the process is applicable under the OSHA Process Safety Standard. Performing the process hazard analysis is not only a best practice but also a potential OSHA General Duty Clause requirement, especially if an incident does occur and the analysis was never performed. Answer B is not correct since there is not a license for processionals to conduct process hazard analyses.

State compensation boards are a LOW FENCE for hearing loss disability claims because: Of inaccuracies in audiograms Small hearing losses aren't disabling To avoid litigation later on To lower worker's compensation costs

*Small hearing losses aren't disabling Low fence means that they set minimum dB loss before a worker is eligible for compensation. This also is done to account for presbycusis (the natural hearing loss due to aging)

Fire has various stages of burning. all the following are true EXCEPT Incipient Stage - No viable smoke, flame or significant heat is developed, but a significant amount of combustion particles are generated over a period of time Smoldering Stage - The quantity of combustion particles decreases to the point where they become almost invisible Flame Stage - The point of ignition occurs and flame start Heat Stage - Large amount of heat, flame, smoke and toxic gases are produced

Workers Compensation is determined by: Federal law Casualty insurance companies State law Unions

*State law Workers' Compensation is required by state law as are its benefits. Although the laws and benefits may vary between the 50 states that have Workers' Compensation, there is agreement on its basic principles.

If a small mobile crane with rubber tires has struck a power line and is apparently dead, lying across the crane boom, what is the proper course of action for the crane operator? Jump from the crane and run away Stay in the crane until the emergency crew arrives Have an oiler knock the power line from the boom with a wood pole Swing boom back and forth until the line breaks or falls off

*Stay in the crane until the emergency crew arrives Each power line contact situation poses different problems. However, the generally accepted guidance is for the crane operator to stay in the cab until power company emergency crews arrive. Often power lines are equipped with fault clearing re-closers, which will reapply power to a faulted line after a few minutes. The re-closer can cycle three or four times before the line is really disconnected and then it is still unsafe because of cross feed situations. Departing the cab should only be considered if a fire or other situation requires it. Jumping from the cab with feet together is the only safe departure method. Contact must be avoided with the energized crane and earth and step potential must be kept at a minimum.

What is an example of an unfired pressure vessel? Boiler Steam jacketed kettle Any vessel directly experiencing flame Copper jacketed steam kettle

Given that incident investigations require resources (time and money), what would be an efficient method to maximize your company's ability to harvest as much information from each incident investigation that is conducted? Perform a formal incident investigation one very incident regardless of complexity and consequence. Perform a formal incident investigation on every complex incident and on every incident with a high consequence. Trend all incidents; perform a formal incident investigation on every complex incident, on every incident with a high consequence, and on other incidents that show a trend. Perform a formal investigation on a randomly selected set of incidents.

*Trend all incidents; perform a formal incident investigation on every complex incident, on every incident with a high consequence, and on other incidents that show a trend The key is trending. An incident can be as minor as a process upset leading to 5 seconds of downtime to a safety-related fatality due to a highly complex sequence of events. No company can afford to investigate every incident unless there is a method for choosing the incidents that will yield the most information and the most opportunity for improving. In some cases, regardless of the complexity, a formal investigation will be commissioned. More frequently, however, a company will want to trend incidents and only perform a formal incident investigation when the trend indicates that there is a higher-than acceptable potential for a repeat. Trending applies to near misses, as well

in coal mining, overexposure to respirable coal mine dust can lead to coal workers' pneumoconiosis (CWP), a lung disease that can be disabling and fatal in its most severe form. the best protective measure to control respirable coal dust during longwall mining shearer operations is face ventilation drum-mounted water sprays cutting drum bit maintenance directional water spray systems

*face ventilation historically, longwall operations have had difficulty in maintaining consistent compliance with the Federal dust standard of 2.0 mg/m3. on most longwall faces, the shearer cutting action is the primary dust source and the largest contributor to respirable dust exposure of face personnel. face ventilation: as with all mining methods, ventilation is the primary means to dilute liberated methane to safe levels. it is also the principle method of controlling respirable dust on the longwall face. providing adequate amounts of air to dilute and carry airborne dust down the face and prevent it from migrating into the walkway has been and continues to be a goal for longwall operators. drum-mounted water sprays: apply water for dust suppression directly at the point of coal fracture and add moisture to the product to minimize dust liberation during coal transport. although very effective at minimizing dust generation at the point of coal fracture, shearer drum water sprays can actually increase airborne respirable dust levels if operated at water pressures that are too high. cutting drum bit maintenance: previous research has sown that bits with large carbide inserts and a smooth transition between the steel shank and the carbide reduce dust levels. the prompt replacement of damaged, worn, or missing bits cannot be overemphasized. a dull bit rubs against the coal, which results in an ineffective use of available cutting force and the inability to penetrate the coal at designed rates. this results in shallow cutting, which greatly increases dust generation. directional water spray systems: water spras can be very efficient air movers and, if applied properly, can be used to augment the primary airflow and reduce the amount of shearer-generated dust that migrates into the walkway near the shearer. water sprays mounted on the shearer body act very much like small fans, moving air and entraining dust in the direction of their orientation. poorly designed shearer-mounted spray systems with nozzles directed upwind as the cutting drums actually force dust away from the face; where it mixes with clean intake air and is carried out into the walkway over shearer operations

Typical forces include flowing, mixing, pouring, pumping, filtering, or agitating materials where there is the forceful separation of two like or unlike materials. Examples of static generation are common with operations involving the movement of liquid hydrocarbons, gases contaminated with particles (ex. metal scale and rust), liquid particles (ex. paint spray, steam), and dust or fibers (ex. drive belts, conveyors). The static electric charging rate is increased greatly by increasing the speed of separation (ex. flow rate and turbulance), low conductivity materials (ex. hydrocarbon liquids), and surface area of the interface (ex. pipe or hose length, and micropore filters). Protection from effects of static electricity include: identification of potential static buildup areas; measures to reduce the rate of static electricity generation; and provisions to dissipate accumulated static electricity discharges. Control measures include bonding and grounding, inerting, and humidity control. The lower the humidity, the higher the potential for static electricity buildup

Which of the following is NOT an example of protective footwear? safety-toed boots metatarsal guards molders (foundry) shoes conductive footwear

*metatarsal guards Metatarsal guards are not shoes; they typically are strapped to the outside of a shoe to protect the instep area from impact and compression. Metatarsal guards are typically made of aluminum, steel, fiber or plastic Safety shoes have impact-resistant toes and heat-resistant soles that protect the feet against hot work surfaces common in roofing, paving and hot metal industries. The metal insoles of some safety shoes protect against puncture wounds. Safety shoes may also be designated to be electrically conductive to prevent the buildup of static electricity in areas with the potential for explosive atmospheres or nonconductive to protect workers from workplace electrical hazards Electrically conductive shoes provide protection against the buildup of static electricity. Employees working in explosive and hazardous locations such as explosives manufacturing facilities or grain elevators must wear conductive shoes to reduce the risk of static electricity buildup on the body that could produce a spark and cause an explosion or fire. Foot powder should not be used in conjunction with protective conductive footwear because it provides insulation, reducing the conductive ability of the shoes. Silk, wool, and nylon socks can produce static electricity and should not be work with conductive footwear. Conductive shoes must be removed when the task requiring their use is completed. Note: Employees exposed to electrical hazards must never wear conductive shoes Electrical hazard, safety-toe shoes are nonconductive and will prevent the wearers' feet from completing an electrical circuit to the ground. These shoes can protect against open circuits of up to 600 volts in dry conditions and should be used in conjunction with other insulating equipment and additional precautions to reduce the risk of a worker becoming a path for hazardous electrical energy. The insulating protection of electrical hazard, safety-toe shoes may be compromised if the shoes become wet, the soles are worn through, metal particles become embedded int he sole or heel, or workers touch conductive, ground items. Note: Nonconductive footwear must not be used in explosive or hazardous locations Foundry shoes, in addition to insulating the feet from the extreme heat or molten metal, keep hot metal from lodging in shoe eyelets, tongues, or other shoe parts. These snug-fitting leather or leather-substitute shoes have leather or rubber soles and rubber heels. All foundry shoes must have built-in safety toes

during a workplace evaluation for combustible dust, which of the following is of least importance in the prevention of a dust explosion? A documented process hazard analysis and operator training Physical and chemical properties that establish hazardous characteristics of materials used in a facility Housekeeping and predictive/preventative maintenance programs Properly installed and operational sprinkler systems

*properly installed sprinkler systems sprinkler systems and distance to a means of egress are examples of loss reduction not loss prevention. a dust explosion involves determining the actual hazard, as well as the manufacturing process that led to the high dust concentration levels. safety professionals should be thoroughly familiar with physical and chemical properties that establish hazardous characteristics of materials used in a facility. the facility should have a documented process hazard analysis, and SH&E professionals should be familiar with hazards identified int he study. a management of change program should be implemented. also, SH&E professionals should be familiar with requirements of NFPA standards that apply to a facility. one obvious item to assess is housekeeping. poor housekeeping may lead to accumulations of dust on machinery and building structural members. SH&E professionals should also identify hidden areas that may not be obvious while standing at floor level. other areas, such as spaces above drop ceilings and around ductwork junctions and gates, should be inspected. dust can accumulate on elevated building and equipment members. in the event of an initial ignition, the shock wave may shake this accumulation, creating another dust cloud and another potentially greater ignition that can shake even more dust from the elevated members, setting up a chain reaction. process equipment should be designed for the operation in which it is used. typically, initial installation of a process incorporates several features to help mitigate a fire or deflagration. these may include explosion vents on machines and/or buildings. it may be a fast-acting explosion suppression system. gates and dampers may be installed inside of ductwork or equipment. each device should be inspected and tested regularly, with documentation created to record and verify its condition. conductive components should be grounded and bonded. training is another important aspect of a dust hazard mitigation program. operators should be trained on the equipment's operation and maintenance and emergency plans to follow. initial as well as refresher training should be provided, and training records should be maintained.

MSD Risk Factors:

1. Excessive Force - Ex. heavy lifting, pushing or pulling heavy loads, manually pouring materials, or maintaining control of equipment or tools 2. Repetition 3. Awkward postures - Ex. Using positions that place stress on the body, such as prolonged or repetitive reaching above shoulder height, kneeling, squatting, leaning over a counter, using a knife with wrists bent, or twisting the torso while lifting. 4. Static postures 5. Quick motions 6. Compression or contact stress - Ex. Pressing the body or part of the body (such as the hand) against hard or sharp edges, or using the hand as a hammer 7. Vibration - Ex. Both whole body and hand-arm, can cause a number of health effects. Hand-arm vibrations can damage small capillaries that supply nutrients and can make hand tools more difficult to control. Hand-arm vibration may cause a worker to lose feeling in the hands and arms resulting in increased force exertion to control hand-powered tools (ex. hammer drills, portable grinders, chainsaws) in much the same way gloves limit feeling in the hands. The effects of vibration can damage the body and greatly increase the force which must be exerted for a task. 8. Cold temperatures - Ex. In combination with any one of the other risk factors, may also increase the potential for MSDs to develop. For example, many of the operations in meatpacking and poultry processing occur with a chilled product or in a cold environment. 9. Combined exposure to several risk factors - Ex.

The ISO standard that covers environmental management is? 9000 10000 12000 14000

*14000 ISO 9000 "quality management" and ISO14000 "environmental management" families are among ISO's most widely known standards ever. ISO 9000 has become an international reference for quality requirements in business to business dealings, and ISO 14000 looks set to achieve at least as much, if not more, in helping organizations to meet their environmental challenges, There are similarities between environmental, health and safety programs and quality assurance programs. They serve common underlying objectives, share common success and failure measures and use common approaches to achieve objectives. The ISO 9000 family addresses "quality management". This means what the organization does to fulfill: - Customer's quality requirements - Applicability regulatory requirements, while aiming to enhance customer satisfaction Continual improvement of its performance in pursuit of these objectives The ISO 14000 family addresses "environmental management" meaning what the organization does to: minimize harmful effects on the environment caused by its activities, and to achieve continual improvement of its environmental performance.

What is primary function of a loss control system? Assess risk, establish effective risk control measures, and elimination of risk Establish effective risk control measures for hazardous conditions, establish effective control measures, elimination of risk. Identify hazardous conditions, assess their risks, and establish effective risk control measures. Assure compliance with applicable regulatory requirements and eliminate residual risk

*Identify hazardous conditions, assess their risks, and establish effective risk control measures. Cannot ever eliminate risk! As described in Assurance Technologies, a loss control system must be able to identify the hazardous conditions as well as understand the real risks associated with those hazardous conditions. A loss control system is incomplete if it solely identifies hazardous conditions and does not take action to understand the risks. Therefore, the actions taken are relative to the risks associated with the hazardous conditions.

Under which category do the following activities belong? A major construction project management team implemented a series of toolbox safety meetings held at the beginning of each shift; housekeeping initiatives; barricade performance for elevated areas; and management walk-through audits to demonstrate leadership and commitment. Union organizing inhibitors Leading indicators Lagging indicators Cost indicators

*Leading indicators According to authors Marlowe and Skrabak (2007), the selection of leading indicators is largely judgmental and only time will tell whether the indicators selected are the right ones. It seems logical to suggest that the leading indicators selected should relate directly to opportunities to reduce risk by improving those safety management processes that analysis indicates need improvement, on a prioritized basis. In safety-related literature, the most commonly identified lagging indicators are accidents and cost trends, and sometimes near misses. Toolbox safety meetings held at the beginning of each shift; housekeeping; barricade performance for elevated areas; and management walking around to show leadership and commitment are generally considered examples of leading indicators.

Which system has as its primary functions to identify hazardous conditions, assess their risk, and establish effective risk control measures? Risk Control Risk Management Loss Control Loss Management

*Loss Control

Potential disadvantage of matrix management include all the following except: Power struggles Increased costs Groupitis Meeting attendance

*Meeting attendance Matrix management has the potential to include power struggles, which may result from the two-boss system. Team members may become too focused on themselves and develop "groupitis", losing sight of important program goals. The matrix often creates increased cost as overhead rises.

According to Federick Herzberg's work, which of the following factors is a hygiene factor, as opposed to a motivational factor? Money Recognition Responsibility Achievement

*Money Frederick Herzberg in his book "Work and the Nature of Man" develops a motivation-hygiene theory. The theory attempts to explain how persons are satisfied by certain intrinsic job factors while being motivated by other extrinsic factors that are quite peripheral to the job being performed. Satisfaction is influenced by: - Money - Status - Relationships with Boss - Company policies - Work rules - Working Conditions Motivation is influenced by: - Achievement - Recognition - Enjoyment of work - Possibility of promotion - Responsibility - Chance for growth Hygiene = satisfaction factor (physical) Motivation factor (non-physical)

Which of the following factors does not affect how individuals behave pertaining to workplace safety? Attitudes toward safety Views regarding team effort Recognition for personal efforts Moral standards

*Moral standards The safety culture is a group's attitude that everyone in the group will try to behave in a way that protects the safety of each other. Recognition will reinforce their trust in the culture. An important factor in developing a safety program is to incorporate concepts of job enrichment, participation and employee-centered leadership. Management will most likely support a proactive safety effort when prevention of losses relates to achievement of company objectives.

The closed loop system known as The Behavioral Based Safety Process includes identifying critical behaviors, problem solving to develop an Action Plan, measuring performance and evaluating for acceptable progress. Identify the final step required to finish the loop. Nothing more is required; the loop is complete Management must become involved in the process Employee committees are formed to define penalties for non-improvement Accident and injury data is collected for inclusion into performance reports

*Nothing more is required; the loop is complete According to "The Behavior-Based Safety Process" by Krause, Hidley and Hodson, the process is as shown below. If improvement progresses at an acceptable rate, then the process is working. If the improvement rate is unacceptable, the existing Action Plan must be modified. The behavioral approach uses operational definitions, measurements and feedback on safety-related issues, along with goal setting as key components to improve safety.

The Z10 is a management system standard compatible and harmonized with quality (ISO 9000 series) and environmental management systems (ISO 14000 series). Which of the following best describes these standards? Specification Standards Compliance Standards Performance Standards Regulatory Standards

*Performance Standards The drafters of these standards set out to ensure that it could be easily integrated into any management systems an organization has in place. This flexibility is characteristic of a Performance Oriented Standard. Z10 adopts from and is in harmony with the International Labor Organization's Guidelines on Occupational Health and Safety Management Systems, ILO-OSH 2001

The basic approach, according to many management systems, includes 4 sequential steps Plan, organize, develop, evaluate Plan, organize, implement, control Analyze, design, develop, implement Analyze, design, implement, evaluate

*Plan, organize, implement, control Many management experts use such terms as "planning, organizing, leading and controlling the use of resources" or "Planning, organizing, activating, and controlling".

The factors which makes the greatest impact on whether an employee will or will not work safely are Strength and endurance Recognition, attitude and team spirit Emotional, moral and physical factors Experience and workplace design

*Recognition, attitude and team spirit Many behavior-based safety experts agree that the most critical factors are team spirit, recognition and attitude. The major factors in work discontent are company policy, interpersonal relationships and supervision. The best way to reduce injuries and property damage in the future is to systematically reinforce positive employee actions and behavior. The safety culture is a group's attitude that everyone in the group will try to behave in a way that protects the safety of each other. Recognition will reinforce their trust in the culture. An important factor in developing a safety program is to incorporate concepts of job enrichment, participation and employee-centered leadership. Management will most likely support a proactive safety effort when prevention of losses relates to achievement of company objectives.

Which of the following is not a characteristic of integrated performance assurance, safety and health, and quality assurance programs? Require common intangible asset control Serve common underlying objectives Share common success and failure measures Use common approach to achieve objectives

*Require common intangible asset control Although industry generally separates, the compliance, SH&E and quality programs, these functions have many similarities, including: - Serving common underlying objectives, such as performance assurance or risk management - Using a common approach to achieve objectives, such as activity-specific evaluation or planning and oversight - Sharing common success and failure measures, such as cost, schedule, violations or liabilities - The first step in establishing a good corporate quality plan is to determine customer requirements.

ILO-OSH 2001:

International Labor Organization Guidelines on Occupational Safety and Health Management Systems The ILO, a UN agency that brings together governments, employers, and workers of its member states, has developed voluntary guidelines on safety and health management systems. The guidelines are designed as an "instrument for the development of a sustainable safety culture within the enterprise and beyond." The key elements of the guidelines are built on the concept of continuous improvement. For more info: ilo.org

OSHA's VVP:

OSHA's Voluntary Protection Program (VVP) The OSHA VVP recognizes and partners with businesses and worksites that demonstrate excellence in occupatonal safety and health. To qualify for one of the VVPs, applicants must have in place an effective SHMS that meets rigorous performance-based criteria. OSHA verifies qualifications through a comprehensive onsite review process. Using one set of flexible, performance-based criteria, the VVP process emphasizes: Management accountability for worker safety and health; continual identification and elimination of hazards, and active involvement of employees in their own protection.

Risk Tolerance is

an organization's readiness to bear the risk after risk treatment in order to achieve its objectives

Mishap is

an unplanned event or series of events resulting in death, injury, occupational illness, damage to or loss of equipment or property, or damage to the environment.

What is ISO 14000 series?

is a series of environmental management standards developed and published by the ISO for organizations. The ISO 14000 standards provide a guideline or framework for organizations that need to systematize and improve their environmental management efforts

Acceptable Risk is

that part of identified mishap risk that is allowed to persist without taking further engineering or management action to eliminate or reduce the risk, based on knowledge and decision making. The system user is consciously exposed to this risk. A risk level achieved after risk reduction measures have been applied. It is a risk level that is accepted for a given task (hazardous situation) or hazard. For the purpose of this standard, the terms "acceptable risk" and "tolerable risk" are considered to be synonymous.

Risk is defined as

the combination of the severity of a defined exposure with its frequency of occurrence. The technique that effectively decreases a project's schedule risk without increasing the overall risk is to incorporate slack time into the project's critical path schedule early in project planning.

Risk is

the effect of uncertainty on objectives

Severity is

the extent of harm or damage that could result from a hazard related incident or exposures

Loss Control is

the proactive measures taken to prevent or reduce loss evolving from accident, injury, illness and property damage. The aim of the loss control is to reduce the frequency and severity of losses. Loss control is directly related to human resource management, engineering and risk management practices.

A successful management system, according to OHSAS 18001, should be based on all the following except: A generic occupational health and safety policy Identification of occupational health and safety risks, along with legal requirements Objectives, targets, and programs that ensure continual improvements Management activities that control occupational health and safety risks

*A generic occupational health and safety policy OHSAS 18001 is an Occupational Health and Safety Assessment Series for health and safety management systems. It is intended to help an organization to control occupational health and safety risks. It was developed in response to widespread demand for a recognized standard against which to be certified and assessed. OHSAS 18001 will measure managements systems with regards to several dimensions. The extent of application will depend on such factors as the organization's occupational health and safety policy, the nature of its activities, and conditions under which it operates. A successful management system should be based on these factors: - An occupational health and safety policy is appropriate for the company - Identification of occupational health and safety risks is documented, along with legal requirements - Objectives, targets, and programs ensure continual improvements - Management activities control occupational health and safety risks - Monitoring of occupational health and safety system performance is constant - Continual reviews, evaluation, and system improvement are conducted

An accident including a company vehicle that impacted an overpass support structure involved a company's driver. All company vehicle records are requested by the NTSB. According to 49CFR, what must be provided? Only the records deem necessary by safety supervisor Records not required All information requested by NTSB Only records insurance company deems necessary

*All information requested by NTSB According to 49CFR831, "The Safety Board may issue a subpoena, enforceable in Federal district court, to obtain testimony or other evidence. Authorized representatives of the Board may question any person having knowledge relevant to an accident/incident, study, or special investigation. Authorized representatives of the Board also have exclusive authority, on behalf of the Board, to decide the way in which any testing will be conducted, including decisions on the person that will conduct the test, the type of test that will be conducted, and any individual who will witness the test."

A manufacturer must keep records relating to product safety for what period of time? As long as possible Life of product guarantee Well beyond life of the product Term of employment plus 30 years

*As long as possible Due to product liability claims, a manufacturer should keep product safety records as long as possible. Some states may have limits on time period, while other states do not and that is where lawsuits often originate. Term of employment + 30 years applies to medical & exposure records and SDSs

Once a chemical has been classified, the hazard(s) must be communicated to target audiences. The exploding chest pictogram represents which hazard class? Carcinogen Irritant Acute Toxicity Environmental Toxicity

*Carcinogen The GHS symbols have been incorporated into pictograms for use on the GHS label. Pictograms include the harmonized hazard symbols plus other graphic elements, such as borders, background patterns or colors which are intended to convey specific information. For transport, pictograms will have the background, symbol and colors currently used in the UN Recommendations on the Transport of Dangerous Goods, Model Regulations. For other sectors, pictograms will have a black symbol on a white background with a red diamond frame. A black frame may be used for shipments within one country. The GHS pictogram for the same hazard should not be located where a transport pictogram appears.

What is the most effective method to fix accountability for environmental, safety and health losses? Charge associated cost to work center Compare incident rates with like companies Require supervisor to make weekly presentations on their status Compare each work center and make an example out of the bottom 10%

*Charge associated cost to work center According to Dr. Roger Brauer in Safety and Health for Engineers, "Making safety part of a supervisor's appraisal is one means of achieving in an organization. Companies that use cost accounting to encourage safety have the lower accident rates."

Based on the OHSAS 18001 guidelines that all management systems should be suitable, adequate and effective, which of the following situations indicate that a management evaluation should be performed? Profits are down from preceding year ES&H director has been held by three individuals during previous 18 months Company's environmental performance has been questioned by local "green" group Company's safety performance is 40% lower than previous year

*Company's safety performance is 40% lower than previous year The purpose of adopting OHSAS 18001 Health and Safety Management System is to maintain continuous improvement. IF the management system finds a significant reduction in company safety performance, it should indicate that a comprehensive management review of the items is warranted.

Should an inspector wish to acquire some structural details for the comprehensive survey, including floor loading at a building site, he/she should Ask the plant superintendent to relay information from posted floor loading signs in the facility Have OHST evaluate conditions during upcoming plant visit Consult published building plans or have a structural engineer conduct a structural analysis Obtain a floor load handbook and evaluate any suspicious conditions during plant visit

*Consult published building plans or have a structural engineer conduct a structural analysis Accurate data is a must when evaluating floor loading in an industrial environment. If data is not readily available from reliable sources, the best choice is to have a competent engineer perform a structural analysis. OSHA at 1910.22 states "In every building or other structure, or part thereof, used for mercantile, business, industrial, or storage purposes, the loads approved by the building official shall be marked on the plates of approved design which shall be supplied and securely affixed by the owner of the building, or his duly authorized agent, in a conspicuous place in each space to which they relate." "It shall be unlawful to place, or cause, or permit to be placed, on any floor or roof of a building or other structure a load greater than that for which such floor or roof is approved by the building official."

Which of the following are GHS signal words that indicate the relative degree of severity of a hazard? Warning, Caution Danger, Warning Caution, Danger Hazardous, Dangerous

*Danger, Warning The signal word indicates the relative degree of severity a hazard. The signal words used in GHS are: "Danger" for the more severe hazards, and "Warning" for the less severe hazards. Signal words are standardized and assigned to the hazard categories within endpoints. Some lower level hazard categories do not use signal words. Only one signal word corresponding to the class of the most severe hazard should be used on each label. The GHS hazard pictograms, signal word and hazard statements should be located together on the label. The actual label format or layout is not specified in GHS. National authorities may choose to specify where information should appear on the label or allow supplier discretion.

Using the Management Grid by Robert Blake and Jane Mouton, illustrating management styles by drawing a grid with a Y axis Concern for People and an X axis Concern for Production, a 9,1 supervisor could be called a Country Club Manager Dictator Workaholic Company Man

*Dictator The 1,1 supervisor is indifferent. The 9,1 supervisor is the one who is interested more in production than the interests of their employees and thus would be labeled a Dictator or Authority-Obedience manager. A 9,9 would be considered a Team Manager, a 1,9 would be a country club manager and a 5,5 would be considered a middle-of-road manager.

Which of the following would be considered the primary talent of a Safety Professional? Out-sources as many responsibilities as possible Recognized as the boss' "right hand man" Displays continuous and flexible learning Strictly adheres to company policy guidelines

*Displays continuous and flexible learning Managers that deliver under high performance expectations of current dynamic times must be well educated and continue that education during their career. They must be unrelenting in their efforts to develop, refine and maintain their skills and competencies, which may not agree with their previous training.

The first action to be considered in the hierarchy of control is: Training Elimination of the hazard Personal Protective Equipment Substitution with something less hazardous

*Elimination of the hazard Risks are reduced to an acceptable level through the application of the hierarchy of controls. A hierarchy of controls provides a systematic way of thinking, considering steps in a ranked and sequential order, to choose the most effective means of eliminating or reducing hazards and their associated risks. Acknowledging that premise that risk reduction measures should be considered and taken in a prescribed order represents an important step in the evolution of the practice of safety. These methods are to be applied when new facilities, equipment and processes are acquired; when existing facilities, equipment and processes are altered; and when incidents are investigated. In applying a hierarchy of controls, the desired outcome of actions taken is to achieve an acceptable risk level. Acceptable risk is that risk for which the probability of a hazards-related incident or exposure occurring and the severity of harm or damage that could result are as low as reasonably practical and tolerable in the situation being considered. That definition requires several factors be taken into consideration: - avoiding, eliminating or reducing the probability of a hazards-related incident or exposure occurring - reducing the severity of harm or damage that may result of an incident or exposure occurs - the feasibility and effectiveness of risk-reduction measures to be taken, and their costs in relation to the amount of risk reduction to be achieved.

What is a warning sign's primary purpose? Information for supervisor Information for employees Employees' hazard recognition and comprehension Company protection from OSHA citations and lawsuits

*Employees' hazard recognition and comprehension 1910.145 (extracted) The word "sign" refers to a surface on prepared for the warning of, or safety instructions of, industrial workers or members of the public who may be exposed to hazards. Excluded from this definition, however, are new releases, displays commonly known as safety posters, and bulletins used for employee education. The wording of any sign should be easily read and concise. The sign should contain sufficient information to be easily understood. The wording should make a positive, rather than negative suggestion and should be accurate in fact. "Major message" means that portion of a tag's inscription that is more specific than the signal word and that indicates the specific hazardous condition or the instruction to be communicated to the employee. Examples include: "High Voltage" "Close Clearance" "Do Not Start" "Do Not Use" or a corresponding pictograph used with a written text or alone. "Signal Word" means that portion of a tag's inscription that contains the word or words that are intended to capture employee's immediate attention.

Which principle involves the "Fellow Servant Rule"? Employer must establish a "two-man" rule Employees will not be responsible for each other Rules will be established for more than one worker Employer will not be responsible for injuries caused by another worker

*Employer will not be responsible for injuries caused by another worker The Fellow Servant Rule was a defense which, prior to the enactment of workers' compensation laws, could be used by an employer to protect him/herself when sued by an employee for damages from injury caused by one or more fellow employees Assumption of Risk worker knew he/she was involved in a risky or hazardous occupation Contributory Negligence worker contributed to his/her injury. These were two other pre-workers' compensation defenses for employers The principle of foresee ability deals with liability for actions that result in injury or damage when hazards were foreseeable. Foresee ability is a fundamental legal principle used in product liability cases. Note: Current disgruntled employees cause the most workplace violence

When attempting to change safety-related workplace behaviors, the following are all basic steps in the process except: Identify critical behaviors Establish a behavior-based safety program Conduct measurement through observation Give performance feedback

*Establish a behavior-based safety program According to the NSC, the 3 basic steps of the behavior based safety process are: 1. Identify Critical Behaviors Employers write, in observable terms, what employees should do to properly perform their jobs. The safety and health professional can list a few critical behaviors or a complete inventory, depending on the scope and results desired. 2. Conduct Measurement Through Observation Trained observers watch the workplace to determine if listed behaviors are performed safely or unsafely. The total number of observed behaviors is divided into the number of safe behaviors to obtain a percentage figure for safe behaviors. 3. Give Performance Feedback The percentage figure for safe behaviors is shown on a graph displayed in the workplace. At regular intervals, behaviors are again observed and new safe behavior figures are added to the graph. Studies show this critical feedback will improve safety behaviors. Praise and recognition from managers or peer pressure can be effective ways to encourage and reinforce safe behaviors. Once data is collected the data analysis includes: - closing the improvement loop - identifying and correcting equipment and design barriers - establishing procedures and solutions instead of temporary corrections

To adjust Worker's Compensation Insurance Rates, a company must use: Experience Modification Rate Incident Rate Worker's Compensation Mod Rate Accident Rate

*Experience Modification Rate The insurance industry uses EMR for workers' compensation insurance as a means of determining equitable premiums. These rating systems consider the average incident losses for a given firm's type of work and amount of payroll and predict the dollar amount of expected losses due to work-related injuries and illnesses. Modification rates charged by private carriers are usually affected by risks beyond the insured's control, products produced or services provided and potential for catastrophic accidents.

In a parallel component arrangement, the failure of one, two, or three components would not result in output failure (all four components must fail to produce output failure). Assuming the failure rate is the same for all components, which of the following formulas should be used for computing the probability of failure for this system? (C^2)-(F^4) C1+C2+C3+C4 F(e^(-t/m)) F1xF2xF3xF4

*F1xF2xF3xF4 All must fail for system to fail, means x not + Since the components are in parallel, the configuration indicates an "AND" gate situation, that is C1 and C2 and C3 and C4 must fail before the output fails. The symbol for an "AND" gate is "*" which indicates multiplication, this leads to the correct answer. Multiply the failure rates of each component. F1xF2xF3xF4, or since the failure rates are all the same, F^4 Note: When dealing in probability of failure the general rules are: - Parallel construction indicates "AND" = multiply - Series construction indicates "OR" = addition

The most correct statement concerning the Failure Mode Effects and Criticality Analysis (FMECA) is FMECA is an extension of FMEA FMECA is a tool of the nuclear industry FMECA is a quality tool, not a system safety tool FMECA is reliability, not hazard based

*FMECA is an extension of FMEA The FMECA is generally considered to be a reliability-based analysis. The process provides an exhaustive search for component failure that will affect system operations. The search may uncover failures that will cause hazards or damage, but its main objective is to determine the system reliability. The method enlargement to include the "Criticality" or critical ranking of components results in the FMECA. The FMECA searches for parts or components that will contribute to the system failure and ranks them by their probability to cause a hazard or ability to affect the system safety. The nuclear industry discourages use of the term FMECA in favor of FMEA because of the nuclear specific use of the term "Criticality", which refers to the amount of radioactive material necessary to sustain a chain reaction (Critical Mass). Quality generally means the same thing as Safety

Which of the following defines a system safety technique that selects an undesired event whose possibility or probability is to be determined and then reviews system requirements, functions, and designs to determine how the top or initial event could occur? Fault Tree Analysis Boolean algebra Preliminary Hazard Analysis (PHA) Failure Mode and Effect Analysis (FMEA)

*Fault Tree Analysis = top down analysis This is a description of Fault Tree Analysis, which uses deductive analysis involving reasoning from the general to the specific. Most other safety analysis use inductive reasoning and progress from a specific item to the general overall failure.

A company's CEO and general manager ask the safety director where in the organizational structure is the best place for the safety function. The preferred placement of the safety function is Personnel Support Operations General Manager staff

*General Manager staff Several different answers could be acceptable. According to the NSC, the safety professional advises and guides management, supervisors, foreman employees and such departments as purchasing, engineering and personnel on all matters pertaining to safety. Formulating, administering, monitoring, evaluating and improving the incident prevention program are additional responsibilities. The general safety and health professional belief is that the safety and health effort should report to a function with power and ability control and correct problems, specifically, the General Manager. Root causes of mishaps can exist in any of the elements in a company, as can the interrelated causes of accidents. The best place for safety expertise, however, is in a staff function reporting to the senior executive.

Employee motivation or change, a primary behavior model, does not include which of the following? Specifying objectives and goals Having the ES&H department write procedures Giving reinforcement and feedback Gaining commitment from employees and management

*Having the ES&H department write procedures The Organization Behavior Model (OBM) approach to employee motivation or change includes specifying objectives and goals, giving reinforcement and feedback and gaining commitment from employees and management. Goals are frequently incorrectly developed, which makes them likely to fail. They must be attainable and employees must believe they are relevant and worthwhile.

What is a neutral or irrelevant event effect in an experiment that is intended to produce the same reaction in a participant as if the event were of importance called? Simple effect Placebo effect Hawthorne effect Theory of negative reward

*Hawthorne effect An unplanned change in persons taking part in an experiment who know this is called the Hawthorne Effect. It was first recognized in a study of worker productivity in the Hawthorne plant of Western Electric Company. A physical change was made to the work area, however the factor that caused the change, was the perception that management was trying to improve the work area. Example: Experiment - Adjusted lighting and production increased. Later, they adjusted lighting the other way and production also increased. Lighting adjustments didn't increase production, the thought that someone was attempting to increase production increased production

Only a small percentage of car accidents are the result of mechanical failure. How can a company best control the major cause of driver error? Conducting monthly safety meetings Requiring substance abuse testing of all drivers Hiring only drivers under 40 years of age Implementing a program of driver selection, training, and supervision

*Implementing a program of driver selection, training, and supervision According to the NSC, "Companies can control driver error by introducing a program of driver selection, training and supervision, while vehicle failure can be reduced by implementing a PM program."

A company's health and safety management program's audit reveals that the program has failed to accomplish the stated objective of accident prevention. Accident rates are very poor, as are morale and discipline. Varying standards exist through the company and supervisors openly defy management authority. What is the best explanation for the safety program management failure? Safety director neglects to establish an effective program Top management fails to support the accident prevention effort Management at all levels fails to manage, lead and direct the workforce Procedures to identify correct and safe methods for job accomplishment are ignored

*Management at all levels fails to manage, lead and direct the workforce Safety and the responsibility for achieving it rest with management, primarily with the organization's CEO, but in a shared manner with all other managers. There has always been disagreement in management circles about just how to accomplish safety, but there has always been agreement that management of safety, like all other functions, has to start at the top, and be supported by subordinate executives and managers. Supervisors, foreman and workers develop their attitudes about the importance of safety and health from both formal and informal clues. Management of the safety and health effort is both an art and a science; the director of Health & Safety is merely the functional steward. When safety is effective, the entire management team deserves credit. Likewise, when it fails the entire team shares the blame. Good leadership characteristics include building responsibility, educating, setting expectations and encouraging choices.

Convincing someone to perform desired behaviors or actions is a part of psychology known as Attitude Motivation Judgement Discipline

*Motivation According to Dr. Roger Brauer in Safety and Health for Engineers, this is the definition of motivation. This includes such areas as overcoming personal deficiencies, increasing safety awareness.

Which of the following is the highest safety priority for the typical employee? Dictated safety standards Generic safety statement - "BE SAFE" Perceived control over the risk Individual examples that violate safety standards

*Perceived control over the risk Motivation in safety is highly situation-specific, which means that situational or behavior-specific campaigns (ex. "don't drive and drive") are more likely to have an impact than general campaigns (ex. "BE SAFE"). However, behavior change is likely to be short lived if it is unsupported or sustained by intrinsic beliefs. People are motivated to take risks, as well as to avoid risks, provided they perceive they have personal control over the risk.

Management and Safety Systems built on the principles and process developed by quality pioneer Edward Deming are known as Act-Do-Plan-Check Plan-Do-Check-Act Plan-Act-Do-Check Check-Plan-Do-Act

*Plan-Do-Check-Act Both Quality and EHS management systems are built on the well-known Plan-Do-Check-Act process. Briefly stated, the purpose of standards is to provide organizations with an effective tool for continuous improvement in their occupational health and safety management systems to reduce risk of occupational injuries, illnesses and fatalities.

Risk is a combination of: Frequency of episodes of an adverse event and probability of occurrence of the adverse event. Probability that an adverse event will occur and consequences of the adverse event. Probability that a hazardous condition exists and consequences of the hazard. Exposure and consequences to a hazard.

*Probability that an adverse event will occur and consequences of the adverse event. Risk is defined as the probability that a substance or situation will produce harm under specified conditions. Risk is a combination of 2 factors: 1. the probability that an adverse vent will occur and 2. the consequences of the adverse event. Risk encompasses impacts on public health and the environment, and arises from exposure and hazard. Risk does not exist if exposure to a harmful substance or situation does not or will not occur. Hazard is determined by whether a particular substance or situation hast he potential to cause harmful effects. Risk is the probability of a specific outcome, generally adverse, given a particular set of conditions. (ANSI Z10-2012)

Which of the following is not one of the major provisions of the consensus standard incorporating best practices in OHSMS? Application of a prescribed hierarchy of controls to achieve acceptable risk levels Design reviews Regulatory compliance Management of change systems

*Regulatory compliance The ASSE/ANSI Z10-2012, OHSMS consensus standard applicable to organizations of all sizes. The standard provides safety professionals and senior management with a well-conceived, state of the art concept and action outline to improve safety & health management systems. In crafting Z10, the intent was not only to achieve significant safety and health benefits through its application, but also to impact favorably on productivity, financial performance, quality and other business goals. There is no provision specifically dedicated to regulatory compliance. The key provisions pertain to risk assessment and prioritization, applying a prescribed hierarchy of controls to achieve acceptable levels of risk by designing reviews, managing change systems; having safety specifications in procurement systems; and conducting safety audits.

The risk remaining after preventative measures have been taken is called: Acceptable risk Tolerable risk Unacceptable risk Residual risk

*Residual risk In ANSI Z10, risk is defined as an estimate of the combination of the likelihood of an occurrence of a hazardous event or exposure(s), and the severity of injury or illness that may be caused by the event or exposures. According to ANSI/ASSE/ISO Guide 73 (Z690.1-2011) Vocabulary for Risk Management, risk is simply the effect of uncertainty on objectives. Risk tolerance is an organization's readiness to bear the risk after risk treatment in order to achieve its objectives. Risk acceptance is an informed decision to take a particular risk. Acceptable risk is a residual risk level achieved after risk reduction measures have been applied. It is a risk level that is accepted for a given task (hazardous situation) or hazard. The terms "acceptable risk" and "tolerable risk" are considered to the synonymous. Residual risk is defined as the risk remaining after preventative measures have been taken. No matter how effective the preventive actions, residual risk will always be present if a facility of operation continues to exist.

Which of these terms refers to someone identified with a group or category with oversimplified attributes associated with that person/group? Selective perception Stereotype Halo Effect Projection

*Stereotype According to "Management" by John R. Schermerhorn, Jr., this is the definition of stereotype.

In order to select a system from among three potential safety design candidates, a Safety & Health consultant must recognize system failure will result in a loss, regardless of choice. An elementary design for each system showing probability of failure is shown below using standard "fault tree" symbols. Which system has the lowest overall failure probability? System "A" Failure: 2x10^-3 AND 5x10^-4 System "B" Failure: 7x10^-7 OR 3x10^-7 System "C" Failure: 1x10^-6 System A has a lower probability, and offers redundancy System B has a lower probability, but has 2 potential single point failures System C is the simplest and has lowest probability The probability is the same for all 3 systems

*The probability is the same for all 3 systems round/arched top = multiply = AND = all systems must fail for system to fail = parallel system pointed top = add = OR = if one system fails, the whole system fails = series system Since the severity and probability for each system is the same, the loss risk is also the same. Given this situation, the selection process would consider overall system cost, deliverability, quality, longevity, human factors, etc.

What type of manager utilizes an external reward and punishment system to affect performance? Theory X Theory Y MBO TQM

*Theory X The Theory X manager (according to Douglas McGregor's Theory) holds that people must be motivated to work by external reward and punishment because they are unmotivated toward work. A Theory Y manager assumes all workers are basically interested and motivated to work and therefore have a reduced need for an external reward system. Management by Objectives (MBO) is a process of joint objective setting between a superior and subordinate. It is also known as Management by Results. The managers meet the following performance objectives: - Target a key result to be accomplished - Identify a date for achieving results - Offer a realistic (measurable) and attainable challenge - Are as specific and quantitative as possible A Total Quality Management (TQM) manager functions and directs operations with an organization-wide commitment to continuous work improvement, product quality and totally meeting customer needs, by applying them to all operation aspect. Under TQM an employee's initiative to work safely is achieved by instilling a commitment to quality teamwork and continual improvement. These managers include the line manager who is responsible for activities making direct contributions to the production of the organizations product, the staff manager who has special technical expertise to advise and support the line manager and function managers that are responsible for a support area such as finance, marketing, personnel, etc. Safety Professionals can have line authority if they work under the plant manager in an operational extension (extended) capacity.

If a potential toxic hazard release is identified during a Preliminary Hazard Analysis (PHA) of a new process, what is the best procedure to determine how to protect against the hazard in case of a release or to determine if the hazard is present in work area? Conduct a site analysis and take air samples Determine effects of local meteorological conditions Review design with engineering department Use a computerized Process Flow Sheet for initial evaluation of hazard releases

*Use a computerized Process Flow Sheet for initial evaluation of hazard releases According to the NSC "Fundamentals of Industrial Hygiene", a simple Process Flow Sheet should be drawn to show how and where each toxic material is introduced and how it can be introduced into the work area. This could include evaluating the meteorological conditions and reviewing the process with the engineering staff. After the process is online, safety managers should sample the area to identify any actual releases.

(Under OSHA's VVP) The major elements of an effective management system include:

1. Management Leadership - Establish clear safety and health goals for the program and define the actions needed to achieve those goals. - Designate one or more individuals with overall responsibility for implementing and maintaining the program. - Provide sufficient resources to ensure effective program implementation. 2. Worker Participation - Consult with workers in developing and implementing the program and involve them in updating and evaluating the program. - Include workers in workplace inspections and incident investigations. - Encourage workers to report concerns such as hazards, injuries, illnesses and near misses. - Protect the rights of workers who participate in the program. 3. Hazard Identification and Assessment - Identify, assess and document workplace hazards by soliciting input from workers, inspecting the workplace and reviewing available information on hazards. - Investigate injuries and illnesses to identify hazards that may have caused them. - Inform workers of hazards in their workplace.

SMART "A" - Actionable - means

Create related objectives and actions you can achieve. The objective should be transferable into actionable tasks people can accomplish. Set challenging and purposeful objectives that are realistic.

SMART "M" - Measurable - means

Establish concrete criteria to measure progress on attaining each objective to help you stay the course, reason target dates, and experience achievement that spurs continued effort required to reach objectives. To determine if an object is measurable, ask questions such as: how much? How many? How will I know it is accomplished?

SMART "T" - Time-oriented - means

Establish realistic timeframes, including start and end dates, deliverables, audit points and milestones to mobilize stakeholders to achieve objectives.

OHSAS 18001:2007:

Occupational Health and Safety Management Systems Specification - British Standard This standard specifies requirements for an occupational health and safety management system, to enable an organization to control its risks and improve its performance. The Occupational Health and Safety Assessment Series (OHSAS) Project Group, an international association of government agencies, private industries, and consulting organizations first published the standard in 1999. Since then, there have been 16,000 certifications to the standard in over 80 countries. The 2007 edition reflects lessons learned from users and increases its compatibility with other international SHMS standards and guidelines. A companion document, OHSAS 18002:2000, serves as a guide to implmeneting OHSAS 18001. For more info: bsi-global.com

SMART "R" - Realistic - means

Operationally define objectives and actions you can achieve. The objective should be transferable into actionable tasks people can accomplish. Set challenging and purposeful objectives that are realistic.

Residual Risk is

Overall risk remaining after system safety mitigation efforts have been fully implemented. It is, according to MIL-STD-992D, "the remaining mishap risk that exists after all mitigation techniques have been implemented or exhausted, in accordance with the system safety design order of precedence." Residual risk is the sum of all risk after mishap risk management has been applied. This is the total risk passed on to the user.

The management term "span of control" refers to:

The breadth of a manager's expertise *The number of subordinates a manager can supervise The number of projects a manager can supervise The number of organizations a manager can supervise The well-known principle of "span of control" is defined as recognizing that a manager cannot effectively supervise more than a half dozen subordinate managers.

Six Levels of Action

The following are prioritized from most effective to least effective (adapted from ANSI-Z10,2012): 1. Elimination - Design to eliminate hazards: falls, HAZMAT, confined spaces, materials handling, tools and machinery, etc. 2. Substitution - Substitute for less hazardous materials and equipment, reduce energy, etc. 3. Engineering Controls - Incorporate safety through design such as: Ventilation systems, enclosures, guarding, interlocks, lift tables, conveyors, etc. 4. Warnings - Strategically place signs, alarms, enunciators, labels, etc. 5. Administrative Controls - Standard Operating Procedures (SOPs) such as: Conduct JSAs, job rotation, inspections, training, mentoring, etc. 6. PPE - PPE assessments may result in the use of: safety glasses, goggles, face shields, fall protection, protective footwear, gloves, respirators, chemical suits, etc. Decision makers should understand that with respect to the six levels of action shown in the following hierarchy of controls the methods described in the first, second and third action levels are more effective because they: - are preventative actions that eliminate/reduce risk by design, substitution and engineering measures; - rely the least on the performance of personnel; - are less defeatable by supervisors or workers Actions described in the 4th, 5th, and 6th levels are contingent actions and rely greatly on the performance of personnel for their effectiveness.

Risk assessment is

The process of determining risks to health attributable to environmental or other hazards. This involves evaluating the identified hazard causal factors and then characterizing the risk as the product of the hazard severity times the hazard probability. Processes used to evaluate the level of risk associated with hazards and system issues. - Assure Management commitment, involvement and direction (an absolute) - Select a risk assessment team, including employees with knowledge of jobs and tasks - Establish the analysis parameters - Select a risk assessment technique - Identify the hazards - Consider failure modes - Assess the severity of consequences determine the occurrence probability, prominently taking into consideration the exposures - Define the initial risk - Make risk acceptance or non-acceptant decisions with employee involvement - If needed, select and implement hazard avoidance, elimination, reduction and control measures - Address the residual risk - Document the results - Follow-up on the actions taken

MBO:

management by objectives

Risk Management is

the process by which assessed risks are mitigated, minimized, or controlled through engineering, management, or operational means. This involves the optimal allocation of available resources in support of safety, performance, cost, and schedule.
