FIT TESTING
The effectiveness of a respirator will be reduced if it is not fit tested properly. Therefore, either qualitative or quantitative fit testing must be conducted
prior to the respirator being used.
NOTE: Fit testing is a U.S. Occupational Safety and Health Administration (OSHA), a Canadian CSA and a Brazilian BMOL requirement.
Quantitative Fit Testing
Quantitative Fit Testing (QNFT) can be conducted using a 3M™ Fit Test Adapter 601 and P100 filters such as the 3M™ Particulate Filters 2091
or 7093.
Qualitative Fit Testing
Qualitative Fit Testing (QLFT) with the 3M™ Qualitative Fit Test Apparatus FT-10 or FT-30 can be conducted using any of the NIOSH approved
particulate filters.
Respirators should be fit tested while wearing any personal protective equipment (PPE) the wearer may use in their work environment that may affect
the fit of the respirator (e.g. hoods, hardhats, safety glasses, hearing protections, etc.).
NOTE: For further information concerning fit testing, contact 3M Technical Service at 1-800-243-4630 or a 3M location in your region. In Canada call
Technical Service at 1-800-267-4414.
