Chemicals have the ability to react when exposed to other chemicals or certain physical conditions. The reactive properties of chemicals vary widely and they play a vital role in the production of many chemical, material, pharmaceutical, and food products we use daily. When chemical reactions are not properly managed, they can have harmful, or even catastrophic consequences, such as toxic fumes, fires, and explosions. These reactions may result in death and injury to people, damage to physical property, and severe effects on the environment.

Limitations on the use of mechanical equipment during the performance of roofing work on low-sloped roofs. Correct procedures for the handling and storage of equipment and materials and the erection of overhead protection. Role of employees in fall protection plans. Training Documentation. The training must be documented by a record that contains the name or the identity of the employee trained, the date the training was provided, and either the signature of the person who conducted the training or the signature of the employer. Retraining. Retraining must be provided whenever there is evidence that an employee who has been previously trained no longer possesses the requisite knowledge and skills. It is also required if there are changes in the workplace or changes in the types of fall protection systems or equipment that render previous training obsolete.

Exposure of Blades, 29 CFR 1910.212(a)(5), specifies that all fans within 7 feet of the floor or working level must be guarded. The guard must not have openings greater than one-half inch in width. The use of concentric rings with spacing between them not exceeding a one-half inch are acceptable, provided that sufficient radial spokes and firm mounting are used to make the guard rigid enough to prevent it from being pushed into the fan blade during normal use. The standard would apply to fan blades of cooling fans for motors and pumps, as well as cooling fans and turbine blades for Commercial Air Handling Units, which are 7 feet off the floor or working level.
If I gave you a definition would you be able to tell me what subpart, sub-section and section that it falls under. Example crawl broad would you be able to tell me where the standard is for that and what a crawl broad is.
Subpart M • Anchorage means a secure point of attachment for lifelines, lanyards or deceleration devices. • Body belt (safety belt) means a strap with means both for securing it about the waist and for attaching it to a lanyard, lifeline, or deceleration device. • Body harness means straps which may be secured about the employee in a manner that will distribute the fall arrest forces over at least the thighs, pelvis, waist, chest and shoulders with means for attaching it to other components of a personal fall arrest system. • Buckle means any device for holding the body belt or body harness closed around the employee's body. • Connector means a device which is used to couple (connect) parts of the personal fall arrest system and positioning device systems together.

11. There is going to be some OSHA questions that cover situations that you need to tell him if it is a Serious hazard or other than serious hazard. (Stay away from willful & repeated) Keep it within de Minius, Serious and other than Serious. Get idea of what the fines and penalties would be. How are fines & penalties applied, is it on a per hazard basis, per equipment basis, per person basis, how is that fine escalated?
• Serious Violation- When an employer knows of or should know of a situation that has a definite chance of causing serious injury or death, but does not remedy it, OSHA issues a serious violation. Inspectors must assess a penalty of up to $7,000 for each serious violation, but they can adjust penalties based upon the seriousness of each particular violation, as well as the employer's previous history, the size of the business, and the good faith of the employer. Failure to ensure that employees who carry heavy loads wear steel-toe boots is an example of a serious violation. • Other- than Serious Violation - A violation of OSHA rules that would not usually cause death or serious injury but that is nevertheless related to job safety or employee health is considered an other-than-serious violation. The maximum penalty for each such violation is $7,000. However, inspectors can choose not to levy a fine, or to reduce the penalty by as much as 95 percent. Inspectors make decisions about penalties based on factors such as the size of the business and the cooperativeness of its owner. Failure to provide copies of safety regulations and failure to post required documentation in work areas are considered other-than-serious OSHA violations. • De Minimis Violations - A de minimis violation is a technical violation of OSHA rules that have no direct impact on health or safety. It is the least serious class of violation, and OSHA inspectors do not levy fines or issue citations for these violations. Inspectors verbally inform employers about de minimis violations and list them on the employer's case inspection file. A ladder with 13 inches between rungs rather than 12 inches is an example of a de minimis violation. • Failure to Abate Prior Violation When an employer receives a violation citation, the citation includes a date by which the employer must remedy the situation. If the employer does not do so on or before the specified date, it may be liable for a fine of $7,000 per day from the day after the specified date until it remedies the condition. • The Area Director determines what citations, if any will be issued, and what penalties, if any, will be proposed.
