Fit Test Qualitative
Qualitative fit testing (QLFT) relies on the respirator wearer’s senses to determine if there is a gap in the seal of the respirator to the wearer’s face.
The test agents used in the OSHA-accepted and ANSI-accepted qualitative fit testing protocols are:
- Saccharin – a sweet tasting solid aerosol;
- BitrexTM – a bitter tasting solid aerosol;
What protocols can be used to fit test PFR95* masks?
PFR95* masks are most often fit tested by following the Qualitative
Fit Test protocol outlined in this manual and employing saccharin or BITREX®
as the challenge agent.
