Qualitative Fit Testing is characterized by which of the following?

Qualitative Fit Testing is characterized by an assessment that relies on the test subject's feedback. This method evaluates how well a respirator fits an individual by using a series of exercises and approaches that require the wearer to detect the presence of a specific test agent—often a harmless aerosol or vapor, such as sweet or bitter tasting substances. The participant’s self-reported experience during the test provides the essential data on whether the respirator forms an adequate seal to their face.

This direct reliance on the subjective sensations experienced by the wearer differentiates qualitative fit testing from quantitative methods, which typically measure fit using scientific devices or calculations. In qualitative fit tests, the personal sensation of fit or leakage plays a critical role, ultimately making individual feedback the cornerstone of assessing proper respirator fit.
