Pull one strap over your head and position it around the neck
below your ears (Fig.4a).
Pull second strap over your head and position it high on the back
of your head (Fig.4b).
Tabs on side of respirator may be used to further adjust facepiece
for a comfortable fit as necessary.
Make certain facial hair, hair, jewelry and clothing are not
between your face and the respirator as they will interfere with
fit.
Make certain respirator is completely opened and edges lay flat
against your face.
Adjust for a comfortable fit by pulling bottom edge under chin
while holding top edge on nose (Fig.4c).
Place your fingertips from both hands at the top of the nosepiece.
Use both hands to bend the nosepiece to fit snugly against your
nose and face (Fig.5).
! The respirator may not fit as well if you pinch the nosepiece
using one hand. Use two hands.
Slide fingers down both sides of the nosepiece to seal it against
your nose and face.
Perform a User Seal Check. To check the respirator-to-face seal,
place both hands completely over the respirator and exhale
(Fig.6). Be careful not to disturb the position of the respirator.
If air leaks around the nose, readjust the nosepiece as described in
step 5. If air leaks around respirator edges, adjust position of
straps and make certain respirator edges fit snugly against the
face.
If you CANNOT achieve a proper seal DO NOT enter the
contaminated area. See your supervisor.
