What is considered the least preferred way to control exposure to hazards?

Personal Protective Equipment (PPE) is considered the least preferred way to control exposure to hazards because it functions as a last line of defense rather than eliminating or reducing the hazard itself. While PPE is vital for protecting workers from potential dangers, it does not address the root cause of the hazard. It requires proper use, maintenance, and the willingness of workers to adhere to safety protocols. This reliance can lead to a false sense of security if workers believe that wearing PPE alone is sufficient for protection.

In contrast, the most effective strategies for hazard control focus on eliminating the hazard altogether or significantly reducing exposure through engineering controls and administrative measures. Engineering controls can physically change the workspace or processes to minimize hazards before any worker interaction occurs. Administrative controls can alter work procedures, schedules, or practices to reduce incident risks and exposure times. Therefore, while PPE is essential, it is the least preferred option because it does not prevent the hazard from existing in the first place.
