When should you conduct a qualitative 'fit test' of your respirator?

• A. If you have a significant change in weight
• B. Every 5 years
• C. After initial training
• D. Semi-annually

Answer: (A)

Fit testing ensures the respirator seals properly on your face. A qualitative fit test uses a detectible agent (taste or odor) to reveal leaks around the seal. If you experience a significant change in weight, that can alter facial dimensions and the way the straps sit, which can break the seal even if you’ve passed a fit test before. Because of this, you should re-check the fit after a substantial weight change to be sure the respirator still fits correctly before continuing to use it. The other options don’t reflect when a re-test is typically required: initial training covers the first test, while 5‑year or semi-annual intervals are not standard triggers for a fit test.
