• PPE is designed for specific functions and is not suitable in all situations.

The limitations and drawbacks of safe work practices also apply to personal protective equipment (PPE). Employees need training in why the PPE is necessary and how to use and maintain it. It also is important to understand that PPE is designed for specific functions and is not suitable in all situations.

For example, no one type of glove or apron will protect against all solvents. To pick the appropriate glove or apron, refer to recommendations on the safety data sheets (SDS) of the chemicals being used.

Employees need positive reinforcement and fair, consistent enforcement of the rules governing PPE use. Some employees may resist wearing PPE according to the rules, because some PPE is uncomfortable and puts additional stress on employees, making it unpleasant or difficult for them to work safely. This is a significant drawback, particularly where heat stress is already a factor in the work environment. An ill-fitting or improperly selected respirator is particularly hazardous, since respirators are used only where other feasible controls have failed to eliminate a hazard.
