Do not wear eyeglasses under the face-
piece. The temples or sidebars on eye
glasses will prevent an air-tight seal. If you
must wear glasses, install an approved
spectacle kit listed on the NIOSH approval
matrix insert. Failure to follow this warn-
ing can cause inhalation of contaminated
air, resulting in serious respiratory injury
or death.
Verify that the respirator is properly pre-
pared before donning. See Repairing the
Respirator for Use section. Failure to fol-
low this warning can result in serious
personal injury or death.
DONNING PROCEDURES
1. Loosen the harness head straps on the
facepiece so that the strap end tabs are
approximately 1" from the buckles.
2. With the facepiece
lens facing away,
grasp the temple
straps and neck
straps in each hand.
3. Slightly expand the
harness straps, place
chin into the face-
piece, and pull the
harness over the back
of the head.
4. Support the weight of the mask by hold-
ing the outlet valve assembly in the
palm of one hand. With the free hand,
adjust the facepiece securely to the
face, making sure the chin and nose are
seated securely.
5. While holding the facepiece securely in
position, tighten one temple strap at a
time by pulling straight back (not out) with
small jerks until mask feels snug on that
side.
6. Tighten the other tem-
ple strap in same
manner until both
sides feel the same.
7. Ensure facepiece is centered on face by
looking down at the nosecup, it should
be uniform on each side of the face. If
not, readjust the temple straps.
Note:
Ensure that no hair is under the tabs
and sealing surface. Also, the straps should
not cut into the ears.
8. Evenly tighten the
neck straps by pulling
them straight back.
9. Check that head pad
is centered in the mid-
dle of the back of the
head.
10. If necessary, tighten
the top straps for best
visibility and fit.
NEGATIVE PRESSURE SEAL TEST
The Negative Pressure Seal Test must be
performed each time the facepiece is
donned. You must know the face-to-face-
piece seal is good before entering a haz-
ardous area.
Perform the test as follows:
1. Ensure respirator is assembled properly.
