Episode 89: Conducting a Respirator Fit Test - Part 1

3M Science of Safety

In this episode, Mike Clayton, 3M’s Senior Respiratory Protection Research & Application Specialist for the Personal Safety Division in the United Kingdom joins host Mark Reggers for the first of a two-part series to discuss conducting a respirator fit test. Tight-fitting respirators must seal to the wearer’s face to provide the expected protection. A respiratory fit test ensures that the respirator truly fits and is being worn correctly. Respiratory fit testing applies to all tight-fitting respirators, either full face masks that cover the mouth, nose and eyes and half masks which covers the mouth and nose.
