Full and half-mask respirators can be used safely by people with beards without fear of a leak.

• A. Sometimes
• B. Never
• C. True
• D. False

Answer: (D)

A tight-fitting half- or full-face respirator relies on a continuous seal against the skin to keep contaminated air from leaking in. Facial hair interferes with that seal, creating gaps where air can bypass the filter. Because of that, you can’t rely on a respirator with a beard and expect full protection; a fit test would likely fail, and the level of protection is not guaranteed. To stay protected, shave the sealing area or use a loose-fitting respirator, like a powered air-purifying respirator with a hood, which does not depend on a facial seal. So the statement is false.
