Cleaning and Disinfecting
WARNING!
Do NOT use cleaning substances that can or might attack any part of the device.
Do NOT use alcohol, which can cause deterioration of rubber parts.
Do NOT touch or inhale contaminants.
Make sure to rinse components thoroughly. The residue from cleaning agents can cause skin irri-
tation.
Make sure that there is no water, moisture, or dampness on or in the device components before
returning the device to service. Any moisture on or in the device components can freeze and result
in a malfunction of the device.
Failure to clean and decontaminate the respirator correctly after each use can cause overexposure
to contamination and result in illness, disease, or death.
Failure to obey these warnings can result in serious injury or death.
Make sure that a designated person or the user cleans the device after each use. ANSI standards
recommend that users be trained in the cleaning procedure.
MSA recommends the use of Confidence Plus Germicidal Cleaner (PN 10009971), which cleans and
disinfects components in one operation; retains its germicidal efficiency in hard water to inhibit the
growth of bacteria; and will not deteriorate rubber, plastic, glass, or metal parts. Refer to the label to
prepare the Confidence Plus Germicidal Cleaner.
If the device has heavy smoke residue or dirt accumulation, use a damp sponge with a mild soap solu-
tion or a soft/medium bristle brush to remove deposits that may interfere with normal operation of the
harness (straps and buckles) or APR adapter.
If the Confidence Plus Germicidal Cleaner is not used, wash components in a mild cleaning solution
and make sure to rinse them thoroughly. When cleaning the respirator in normal weather, submerge
the facepiece in a germicide solution for the manufacturer's recommended time.
10.1 Facepiece
WARNING!
Do NOT use cleaning products that contain hydrocarbons or solvents such as nitro-thinner.
Do NOT use radiant heat such as the sun or radiators to dry cleaned parts.
When a drying cabinet is used, make sure that the temperature is not more than 140°F (60°C).
Do a negative pressure seal test after every cleaning, disinfecting, and maintenance procedure,
and after every exchange of parts.
Failure to obey these warnings can result in serious injury or death.
It is only necessary to clean and disinfect the facepiece after each use.
