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. Unthread the thumb screw of the FireHawk M7
Responder HUD and remove the FireHawk M7
Responder HUD from the facepiece bracket.
c. Remove the Clear Command Communication
System (if used).
d. Thoroughly wash the facepiece, drink tube, 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 Responder HUD/FireHawk M7 Control
Module/FireHawk M7 Power Module
f. FireHawk M7 Control Module Gauge and LCD
Cover Lens
g. First Stage Regulator (PR14)
h. Firehawk Responder Second Stage Regulator.
Cover the outlet of the Firehawk Responder
Regulator to prevent water, dirt, or debris from
entering.
4. Inspect the entire air mask as it is reassembled.
Follow the Inspection Instructions.
5. Re-attach the FireHawk M7 Responder HUD
a. Insert the FireHawk M7 Responder HUD into the
facepiece bracket.
b. Finger-tighten the thumbscrew.
6. Re-attach Clear Command Communication System (if
used).
7. Thoroughly dry the facepiece and Firehawk Responder
Regulator after cleaning and disinfecting. The face-
piece can trap water, which could enter the regulator.
