Week 3: Chapter 4: Hazards, Risk & Control
What is Job Description vs Specifications?
-Content and hierarchy specific to a particular job -The requirements necessary to perform the various functions of the job
Hazard identification methods
-Identify hazard -Visible inspection of the workplace or air sample testing -Walk-through surveys -Safety Sampling (safety personnel who record observations of unsafe practices on sampling document) -Hazard Analysis (analytical technique that examines system for most probable hazards having the severest consequences)
What is an Illness?
-Physical and mental conditions resulting from hazards -Can affect the physical and mental health of workes -Needs special attention early than later
Source-Path-Human Controls Controlling hazards by identifying & attacking the?
-Source of the Hazard -The path it travels -Employee of the haazard (slide 36 visual example)
Risk Assessment 3. Risk Control >Methods of risk control
-all methods involve a systematic process for determining where and when a control is necessary. Controls are -Possible -Necessary - Required Example: Source-Path-HUman
Hierarchy of Controls What are the 5 controls/sections to Risk Controls?
1. Elimination -Process of removing hazard 2. Substitution -Replacing materials/equipment/processes for less hazardous ones 3. Engineering Controls -Modding of work processes, materials to reduce exposure to hazards -Installing ventilation/auxillary equipment -First and Most preferred way to deal with hazards 4. Administrative Controls -Management involvement -Training of employees -Rotation of Employees -Envrionmental sampling -Medical Surveillance Example: housekeeping, visible reminders, safety awareness programs.. 5. PPE -Not always possible to protect with admin controls -Clothing, helmets, goggles protect from specific hazards -Least preferred method of controlling hazards -Should never be sole means to protect workers from hazards
Risk Assessement. The Risk Assessment includes which 3 core steps?
1. Hazard Identification 2. Risk Analysis 3. Risk Control
Risk Assessment: 1. Hazard Identification (5 areas) >People >Equipment >Environment >Materials >Processes
1. People -Human factor causes an accident by commision (doing something), poor judgement or omission (failing to do something) 2. Equipment Under certain conditions, the tools/machines use and work near can be hazardous 3. Environment -Improper lighting -Poor ventilation -Adverse Temperature -Poor indoor air quality 4. Materials -Any substance, matter or provisions used for production that have potential to cause harm or loss is handled (such as mixing ammonia and bleach) 5. Processes -The flow of work and factors such as design, pace, and organization of various types of work via policies, procedures and processes.
Hazard Analysis Con't.. What are the 2 types of Analytical Trees?
1. Positive Tree: Illustration of how a job should be done 2. Fault Tree: Illustration of things that can go wrong
Risk Assessment 1. Risk Analysis One hazards are identified, the risk of an accident or injury is determined via risk analysis What are the 2 main pillars of this analysis?
1. Probability -Chance or likelihood that an event will occur and will result in hamr or loss 2. Consequences -The results or severity of the injury (example slide 25)
Define Incident
An unplanned interruption to the standard operation of a service, or a reduction in the quality of that service. An Incident can also be the failure of an IT component that has not yet impacted a service—something is broken or not working as expected.
Define: Hazard Risk Risk Assessement
Hazard any object, action or condition that can be a source of potential adverse health effect, damage, or harm to people, processes, or equipment within the workplace Risk The probability or the extent to which a hazard is likely to cause harm to people, processes, or equipment Risk assessment: The process of hazard and risk identification, analysis, and control
Define risk perception What are the 3 factors of risk perception?
Judgments people make & their behaviour/response when characterizing & evaluating hazardous activities & technologies Factors: -Values, Beliefs, Experience
What is Overexertion Injuries?
overworking the body -Lifting, Awkward posiiton, repetition
Types of Injuries and Illnesses What is Overt Traumatic Injury?
OTI: common cause of workplace accidents is individuals coming into contact with objects, and equipment Example: -Struck by overhead falling objects -Drop material on self -Falls
What is RSI? Origins of RSI? How to avoid?
Repetitive Strain Injury is a stress-related, cumulative type of injury resulting from repetitive movements. (an Overexertion) -Unnatural joint position/posture -Force on hinge joints -Pre-existing conditions (arthritis...) Tennis elbow, golfer's elbow, writer's cramp.. Carpal tunnel. -Should not reach below knee, or raise arms above shoulder for any length of time -Design of work station in comfortable position
Hazard Identification Methods Audits & Reports An Audit program should ensure what? How often to conduct?
Review of Reports -Filed after an incident, accident, or injury -Provides valuable info on hazards Audit Info: -reviews records of all injuries/incidents, workplace design changes -Useful source for cataloguing hazards Audits should ensure safety programs are carried out without restrictions, ensure programs are up to date and deficiencies documented, be carried out by people with understanding of both audit methods and materials being examed Audits should stimulate discussion amongst all workers, and produce conclusions -Conducted Annually -Include all documents (WSIB, Ministry of labour citations..)
