What is an example of a qualitative fit test?

A qualitative fit test is a method used to evaluate how well a respirator maintains a seal around the wearer's face. This particular type of test relies on the user's ability to detect a particular substance that is introduced into the testing environment. The method often involves seeing if the wearer can taste, smell, or otherwise perceive the test agent while wearing the respirator.

Reading the "Rainbow Passage" is a common practice in qualitative fit testing. During this procedure, the individual reads a passage aloud while wearing the respirator. The purpose of this activity is to ensure that the respirator maintains a proper fit and seal as the wearer speaks, which produces various facial movements that might affect the seal. If the wearer can detect the test agent during this reading, it indicates that the respirator does not fit properly.

The other options presented are generally associated with other forms of testing, such as quantitative fit tests or physical assessments, rather than the qualitative method. For instance, the Port-a-Count test uses instruments to provide a measurement of fit rather than relying on the user's sensory perceptions. Using a Dynatech machine also involves equipment that measures the effectiveness of the respirator fit quantitatively. Jumping jacks assessment is more of a physical activity that is unrelated to
