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.
1. Thread top elastic strap through top buckles. Repeat for
bottom strap and buckles.
2. Hold respirator under chin, with nosepiece up. Locate the
upper strap across the crown of the head and the lower
straps below the ears. Straps must not be twisted.
3. Adjust tension: Increase - pull evenly on both ends of top/
bottom straps.
4. Decrease - without removing respirator, push out on back of
buckles.
5. Using both hands, mould noseclip to the shape of the lower
part of the nose to ensure a close fit and good seal. Pinching
the noseclip using only one hand may result in less effective
respirator performance.
6. The seal of the respirator on the face should be fit-checked
before entering the workplace
