Qualitative Respirator Fit Testing
Qualitative Respirator Fit Testing is where a worker’s ability to detect a test agent (taste, odor, or irritation) determines a PASS/FAIL. We use the bitrex or saccharin test agents where a flavored aerosol mist is introduced under a hood in close proximity to the mask wearer to determine the integrity of the seal. The subject is required to perform a series of head and body motions typical of normal daily movement. If the flavored aerosol is undetectable to the subject on completion, the mask seal is adequate and the test is considered a pass. We are also able to provide fit testing using irritant smoke.
