What does a fit test verify?

• A. Verifies a respirator is comfortable and correctly fits
• B. Checks the color or appearance of the respirator
• C. Tests the filtration efficiency of the respirator
• D. Ensures the respirator straps are adjustable

Answer: (A)

A fit test checks whether a respirator forms a proper seal on the wearer’s face so that air is drawn through the respirator material rather than leaking around the edges. It’s about ensuring the respirator fits well and can be worn comfortably in a way that maintains a tight seal during typical movements. If the seal isn’t right, contaminants can bypass the filter, so the test focuses on fit and how well the wearer can maintain that seal, which is why comfort and correct fit are emphasized together. Color or appearance isn’t related to protection or seal, so it isn’t assessed by a fit test. Filtration efficiency is a property of the filter material itself and is evaluated separately from fit testing. While adjustable straps help achieve a good fit, a fit test ultimately verifies that the respirator, when worn as intended, actually seals properly on the face.
