Under the Hierarchy of Hazard Controls, where does an N95 respirator mask fall?

An N95 respirator is classified as PPE (Personal Protective Equipment) — the 5th and lowest level of the hierarchy. PPE includes masks, gloves, gowns, goggles, face shields, and respirators. It is the last line of defense — effective when properly used, but reliant on human compliance and correct fit/use. PPE does NOT eliminate the hazard; it only protects the individual wearing it.
