Which change requires retesting the respirator fit?

• A. An existing respirator style has changed
• B. A different color of the strap
• C. The style of the face piece has changed
• D. A new brand of gloves

Answer: (C)

When a respirator is tested, the goal is to verify that it forms a proper seal on the face. The part that matters most for the seal is the facepiece itself. If the style of the facepiece changes, the way it sits on the face and the contact points around the nose, cheeks, and chin can be different, which can alter the seal. That’s why retesting is required whenever the facepiece style changes. Changes like strap color or even a different glove brand don’t affect the respirator’s seal, so they don’t require a new fit test.
