What are the components of a hazard control hierarchy?

The hierarchy of hazard control is a systematic approach used to minimize or eliminate exposure to hazards in the workplace. The correct components of this hierarchy include elimination, substitution, engineering controls, administrative controls, and personal protective equipment (PPE), which are all designed to address workplace safety effectively.

Elimination involves completely removing the hazard from the workplace, making it the most effective method. When elimination is not possible, substitution can be applied, where a less hazardous material or process replaces a more dangerous one. If these first two methods cannot be employed, engineering controls can be implemented to isolate people from the hazard, such as physical barriers or ventilation systems.

Administrative controls focus on change in work policies or procedures to reduce risk, involving practices such as training or alteration of work schedules. Lastly, when all other methods are insufficient, personal protective equipment is used to protect the worker from the hazard, although this is seen as less desirable since it does not eliminate the hazard itself.

The other options listed refer to various aspects of safety management and training but do not follow the established hierarchy of hazard control that prioritizes methods from most to least effective. This makes the second choice the most comprehensive and accurate representation of the components involved in hazard control hierarchy.
