Cleaning And Disinfecting - MSA FireHawk M7XT Fonctionnement/Entretien

CLEANING AND DISINFECTING

Depending on the cleaning policy adopted, either a designat-
ed 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 recommended. 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
instructions.
• 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 irri-
tate 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 thoroughly, 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 Ultra Elite XT Communication 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 draining).
f. Clean the pressure-demand exhalation valve by press-
ing in on the stem with a blunt object and flushing it
with clean water.
CLEANING AND DISINFECTING
WARNING
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 disin-
fecting 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 opera-
tion 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 M7XT Control
Module/FireHawk M7XT Power Module
NOTE: If the FireHawk M7XT Control Module lens covers exhib-
it 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 rein-
stalling.
f. FireHawk M7XT 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 face-
piece.
b. Finger-tighten the thumbscrew (for FireHawk M7 HUD
only).
6. Re-attach Ultra Elite XT Communication 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.
