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

leaning Solution (P/N 10009971) from MSA is recom-

ended. It cleans and disinfects in one operation. It

etains its germicidal efficiency in hard water to inhibit the

growth of bacteria. It will not deteriorate rubber, plastic,

glass, or metal parts. Refer to label for user instructions.

DO NOT use any cleaning substances that can or

might attack any part of the apparatus.

Alcohol should not be used as a germicide 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 NightFighter Heads-

Up Display System receiver and slide the receiver

from facepiece bracket.

c. Thoroughly wash the facepiece (and nosecup) in the

cleaning solution. A soft brush or sponge can be

used to clean the soiled facepiece.

d.Rinse the facepiece and components in clean,

warm (110°F) water (preferably running and

drained).

e. Clean the pressure-demand exhalation valve by

pressing in on the stem with a blunt object and

flushing with clean water.

f. 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.

. Operate the exhalation valve by hand to be sure it

orks 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 that it was shipped in.

3. In general, only the facepiece requires cleaning and

disinfecting after each use. If the apparatus 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 with URC Assembly (bell or cou-

pling nut connection)

e. NightFighter Heads-Up Display System/Pressure

Gauge/ICM Unit Gauge

f. MMR remote gauge lens

g. First stage regulator

h. MMR second stage regulator. Cover outlet of the

MMR second stage regulator to prevent water, dirt,

or debris from entering.

4. Inspect the entire apparatus as you re-assemble it.

Follow the Inspection Instructions.

5. Re-attach NightFighter Heads-Up Display System

Receiver

a. Slide receiver onto facepiece bracket.

b.Finger-tighten thumb screw.

6. Thoroughly dry the facepiece and regulator after

cleaning and disinfecting. The facepiece can trap

water, which could enter the regulator.
