INSPECTION OF THE RESPIRATOR
If any damage is found in this inspection, remove the respirator from
service and tag for repair by authorized personnel.
1. Inspect the complete respirator for worn or damaged compo-
nents.
a) Inspect hoses and rubber parts which exhibit cracking, splitting,
or brittleness.
b) Inspect harness webbing for cuts, tears, abrasion, fraying, or
indication of heat or chemical damage.
c) Check all buckles and fasteners for proper operation.
d) Check the cylinder retention system for damage and for proper
operation.
e) Verify that the respirator has been properly cleaned.
2. Remove the breathing regulator from the facepiece by pulling back
on the regulator retaining latch and rotating the regulator ¼ turn.
Inspect the gasket on the breathing regulator that seals against the
facepiece for rips or damage that may break the seal.
3. Inspect the breathing regulator for damaged or missing compo-
nents.
a) Verify that the regulator gasket is not damaged and is in place
around the outlet port of the regulator.
b) Verify that the purge valve (red knob) is not damaged and turns
smoothly one-half turn from stop to stop.
FACEPIECE INSPECTION
Examine the facepiece assembly for damaged or worn components. The
facepiece must be complete and in serviceable condition with no worn,
loose, or damaged components. Inspect the facepiece as follows:
1. Inspect the facepiece seal and other rubber components for deforma-
tion, wear, damage, or cracks.
2. Inspect the lens for cracks, gouges, scratches, or any condition that
could impair the operation of the facepiece or the user’s vision.
3. Inspect the lens frame or bezel for damage such as cracks or distor-
tion.
4. Check that all lens frame retainers or bezel screws are present and
installed correctly.
5. Check that all harness anchors are present and operating properly.
6. Inspect the head harness for correct installation with all straps oriented
correctly.
7. Inspect the head harness for damage or worn components.
8. Inspect the voicemitters for dents or damage. Verify that the voicemit-
ters are properly installed and secure in the voicemitter ducts.
9. Inspect the nose cup for cuts or damage. Also look for any signs of
damage to the facepiece port side of the nose cup where the regula-
tor attaches.
Check that the nose cup is properly seated between the flanges of
the voicemitter ducts. See FIGURE 1.
