2. Place the top elastic strap around the head, above the ears. Untwist the strap.

1. Thread top elastic strap through top buckles. Repeat for bottom strap and buckles. Place the bottom elastic strap around the head just below the ears. Untwist the strap.

3. Adjust tension by pulling tabs of each strap, as shown.

4. Using both hands, mould metal nosepiece comfortably to shape of nose.

5. Strap tension may be decreased without removing respirator from the head by pushing out on the back of the buckles. If you cannot achieve a proper fit do not enter contaminated area. See your supervisor.

6. The seal of respirator on the face should be fit-checked prior to wearing in the work area. a) Cover the front of the respirator with both hands, being careful not to disturb the position of respirator. b) Inhale sharply. A negative pressure should be felt inside respirator. If any leakage is detected, adjust position of respirator and/or tension of strap. Retest the seal. Repeat the procedure until the respirator is sealed properly.
