  • Quantitative Fit Testing Advantages and Disadvantage

    OSHA allows for the use of both qualitative and quantitative tests to evaluate a respirator’s fit on an individual. Qualitative fit testing is a pass/fail test to assess respirator fit based on the individual’s response to a test agent. A quantitative fit test assesses respirator fit by numerically measuring leakage into the respirator.
