Fit Check
1. Cover the front of the respirator with both hands being
careful not to disturb the fit of the respirator.
2. (a) UNVALVED respirator - EXHALE sharply;
(b) VALVED respirator - INHALE sharply.
3. If air leaks around the nose, re-adjust the noseclip to
eliminate leakage. Repeat the above fit check.
4. If air leaks at the respirator edges, work the straps back
along the sides of the head to eliminate leakage. Repeat the
above fit check.
If you CANNOT achieve a proper fit DO NOT enter the hazardous
area. See your supervisor.
Users should be fit tested in accordance with national
requirements. For information regarding fit testing procedures,
please contact 3M.

Fitting Instructions
See Figure 1.

headbands to hang freely below hand.
2. Hold respirator under chin, with nosepiece up.
