CLEANING AND DISINFECTING
CLEANING AND DISINFECTING
Depending on the cleaning policy adopted, either a desig-
nated person or the user should clean each device after
each use. ANSI standards suggest that users should be
trained in the cleaning procedure. Confidence Plus
Cleaning Solution (P/N 10009971) from MSA is recom-
mended. It cleans and disinfects in one operation. It
retains its germicidal efficiency in hard water to inhibit the
growth of bacteria. It will not deteriorate rubber, plastic,
glass, or metal parts. Refer to the label for user instruc-
tions.
• DO NOT use any cleaning substances that can or
might attack any part of the air mask.
• DO NOT use alcohol because it may deteriorate
rubber parts.
• If not rinsed thoroughly, cleaning agent residue
may irritate the wearer’s skin.
1. Preparing Solution
a. Follow the instructions with the Confidence Plus
Cleaning Solution.
b. If the Confidence Plus Cleaning Solution is not
used, wash in a mild cleaning solution, rinse thor-
oughly, and submerge in a germicide solution for
the manufacturer’s recommended time.
2. Clean and Disinfect the Facepiece
a. Remove the mask mounted regulator from the face-
piece.
b. Remove the FireHawk M7 HUD or I-HUD. For the
FireHawk M7 HUD, unthread the thumb screw and
remove it from the facepiece bracket. For the
FireHawk M7 I-HUD, remove it from the facepiece
by pulling on both sides with equal force.
c. Remove the communications system (if used).
d. Thoroughly wash the facepiece (and nosecup) in the
cleaning solution. A soft brush or sponge can be
used to clean the soiled facepiece.
e. Rinse the facepiece and components in clean,
warm (110°F) water (preferably running and drain-
ing).
f. Clean the pressure-demand exhalation valve by
pressing in on the stem with a blunt object and
flushing it with clean water.
g. Allow the facepiece to air dry. Do not dry the parts
by placing them near a heater or in direct sunlight.
The rubber will deteriorate.
h. Operate the exhalation valve by hand to be sure it
works properly.
NOTE: Do not force-dry the parts by placing them in a
heater or in direct sunlight. The rubber will deteriorate.
When the facepiece is thoroughly dry, store the facepiece
in the plastic bag in which it was shipped.
3. In general, only the facepiece requires cleaning and
disinfecting after each use. If the air mask is soiled
(i.e. heavy smoke residue or dirt accumulation) use a
sponge damp with mild soap solution or use a
soft/medium bristle brush to remove deposits that
may interfere with normal operation of:
a. Harness (straps and buckles)
b. Cylinder Carrier (band and latch assembly)
c. Cylinder (handwheel, gauge, outlet connection)
d. Audi-Larm Alarm (bell and coupling nut connection)
e. FireHawk M7 HUD or I-HUD/FireHawk M7 Control
Module/FireHawk M7 Power Module/NightFighter
HUD Transmitter
NOTE: If the FireHawk M7 Control Module (integrated
PASS version) lens covers exhibit moisture or dirt, remove
the lens covers to clean properly. The covers can be
cleaned by wiping them off with a mild soap solution.
Rinse the cover and dry completely before reinstalling.
f. FireHawk M7 Chest Mounted Pressure Gauge and
LCD Cover Lens
g. First Stage Regulator (PR14)
h. Firehawk Second Stage Regulator. Cover the outlet
of the Firehawk Regulator to prevent water, dirt, or
debris from entering.
4. Inspect the entire air mask as it is reassembled.
Follow the Inspection Instructions.
5. Reinstall the FireHawk M7 HUD or I-HUD
a. Reinstall the FireHawk M7 HUD onto the facepiece
bracket. Reinstall the FireHawk M7 I-HUD in the
facepiece.
b. Finger-tighten the thumbscrew (for FireHawk M7
HUD only).
6. Re-attach the communications system (if used).
7. Thoroughly dry the facepiece and Firehawk Regulator
after cleaning and disinfecting. The facepiece can trap
water, which could enter the regulator.
