RESPIRATOR REMOVAL
1. Fully loosen all four head straps by lifting up on buckles.
2. Remove respirator by pulling straps over head.
FIT TESTING
The effectiveness of a respirator will be reduced if it is not fitted properly. Therefore, either qualitative or quantitative fit testing must be
conducted prior to respirator being used.
NOTE: Fit testing is a U.S. OSHA and Canadian CSA Z94.4 standard requirement. Therefore, either quantitative or qualitative fit testing must be
conducted prior to the respirator being issued.
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 P100 2091
or 7093.
