Which statement best describes a quantitative fit test?

• A. It measures the amount of leakage into the respirator to assess fit
• B. It measures the battery life of a powered respirator
• C. It assesses the color of the respirator
• D. It assesses the cost of the respirator

Answer: (A)

Quantitative fit testing assesses how well a respirator seals to the wearer’s face by measuring the actual leakage into the facepiece as the wearer performs typical movements. It delivers a numerical value, called the fit factor, which comes from comparing the amount of test aerosol outside the respirator to the amount inside during the test. This objective leakage measurement reveals the effectiveness of the seal, catching small leaks that a user might not feel. It’s focused on seal integrity rather than other factors like battery life, color, or cost, which do not indicate fit. In contrast, qualitative tests rely on the wearer’s senses and give a pass/fail result without a numeric leakage value.
