How do you assess the adequacy of a PPE program within an industrial hygiene framework?

• A. PPE should be the first and only control for all hazards.
• B. Verify hazard controls are layered with PPE as a last resort; ensure proper selection, fit testing, training, maintenance, and replacement.
• C. PPE adequacy is determined solely by the number of PPE types owned.
• D. PPE is optional if ventilation exists.

Answer: (B)

The key idea is that PPE adequacy is judged within the hierarchy of controls: PPE should be a final barrier, used only after hazard controls (engineering and administrative) are in place and not sufficient alone. A robust PPE program is one where hazard controls are layered and PPE is selected specifically for the hazard, fit-tested for the individual (especially for respirators or tight-fitting gear), and supported by training on proper use and limitations. It also requires ongoing maintenance, inspection, cleaning, and timely replacement, with clear donning/doffing procedures and documentation. If ventilation or other controls already reduce risk effectively, PPE should still be available as an additional layer, not as the default or sole solution. Simply owning many types of PPE or using PPE as an optional measure does not ensure adequacy.
