Respiratory protection is only effective if it is correctly selected, fitted and worn throughout the time when the wearer is exposed to respiratory contaminants. Disposable respirators are only effective when there is a good seal between the edges of the respirator and your face. The instant this seal is broken protection is compromised as contaminated air can leak in through any gaps.

These fitting instructions must be followed each time a 3M Cupped respirator is worn.

Be clean shaven. Do not wear with beards or other facial hair that prevent a good seal to the face. Do tie back long hair and remove jewellery so that it does not interfere with the seal to the face.

Face Fit Check – every time before entering the hazardous area.

5. Cover front of the respirator with both hands taking care not to disturb its fit.


- When using an unvalved respirator, exhale sharply. If the respirator bulges slightly and no air leaks are detected between the face and the respirator, a proper seal has been obtained. Then work may proceed.
- When using a valved respirator, inhale sharply. The respirator should collapse slightly indicating a proper seal has been obtained. Then work may proceed.

Also follow “Warning about Face Fit Check” below.

Warning about Face Fit Check

- If air leaks around the nose, re-adjust the nose clip to eliminate leakage by repeating step 4. Repeat Face Fit Check.

- If air leaks at the respirator edges, work the straps back along the sides of your head to eliminate leakage. Repeat Face Fit Check.

If you cannot achieve a proper fit, repeat steps 2-5.

If you cannot achieve a proper fit, DO NOT enter the hazardous area. Consult your supervisor.
