N95 respirator fit test
Positive Pressure Fit Check
The respirator seal must be checked before each use. To perform the ﬁt check, place both hands completely over the respirator, being careful not to disturb the position. Exhale sharply.
If air leaks around your nose, adjust the nosepiece. If air leaks at respirator edges, adjust the straps back along the sides of your head. Perform the ﬁt check again if an adjustment is made. If you cannot achieve a proper ﬁt do not enter area requiring respirator use.
Note: Do not use with beards or other facial hair or other conditions that prevent a good seal between the face and the face seal of the respirator.
