align fi lters.
Step 5: Donning respirator & adjusting fi t
1. Place the respirator over
your mouth and nose
and nose and pull head
harness over the crown
of head.
Adjust the straps so the respirator is comfortable and snug, but do not overtighten.
Note: Decrease strap tension by pushing out on back side of buckles.
Note: Use of the EVF does not change donning steps.
Step 6: Positive Pressure User Seal Check
Place the palm of your hand over the center of the EVF and exhale gently. If
facepiece bulges slightly and no air leaks are detected between your face and the
facepiece, a proper seal has been obtained. If faceseal air leakage is detected, repo-
sition respirator on your face and/or readjust tension of the elastic straps to eliminate
leakage. If you cannot achieve a proper seal, DO NOT enter contaminated area.
