Personal Protective Equipment (PPE) is generally considered less effective than engineering controls because it relies on human behavior for proper use and maintenance. Engineering controls aim to eliminate or reduce hazards at the source by designing safer equipment or altering processes. This direct approach effectively minimizes the risk of exposure before it reaches the worker.

In contrast, PPE serves as a barrier between the worker and the hazard, protecting individuals only when used correctly. It does not eliminate the hazard itself, thus still allowing for the possibility of exposure. Moreover, factors such as comfort, fit, and compliance can influence whether PPE is used correctly and consistently.

While other options like administrative controls, substitution of materials, or isolation of hazards represent proactive approaches to managing risks, PPE is ultimately a reactive measure that depends on correct usage after other controls have failed or are not feasible.
