MAINTENANCE AND CLEANING
CAUTION
Cleaning with solvents may degrade some respirator components and reduce respirator effectiveness.
Inspect all respirator components before each use to ensure proper operating conditions.
1.
Remove cartridge, outserts and quick doff hood (if applicable). Set cartridge aside, away from cleaning
operations.
2. Remove exhalation valve cover.
3. Remove universal second skin (if applicable).
4. If necessary, remove greasy or oily substances from your mask assembly, universal second skin, quick
doff hood and outserts, inside and out with household rubbing (isopropyl) alcohol.
5. Clean the facepiece (excluding cartridge), universal second skin and quick doff hood by immersing in
warm soapy water and scrub with a soft brush until clean. Parts may also be cleaned in a washer.
Note: Water temperatures should not exceed 120° F (49° C). Do not use cleaning agents that contain
lanolin or other oils.
6. Disinfect respirator by soaking in a solution of quaternary ammonium disinfectant or sodium
hypochlorite [1oz (30ml) household bleach in 2 gallons (7.5L) of water], or other disinfectant.
7. Rinse in fresh, warm water and air dry in non-contaminated atmospheres or wipe dry with a
cheesecloth. Do not use tissue paper or a paper towel. Paper may leave behind particles, which may
lodge in the valve seat and prevent proper operation (the valve will leak). Drying temperatures must not
exceed 120° F (49° C).
CAUTION
DS2 is a common agent used in the decontamination of equipment exposed to chemical military agents.
DS2 may damage the voicemitters of the mask assembly. When exposed to DS2, rinse voicemitters as soon
as possible with clean water.
OPTIONAL ACCESSORIES
Respirator parts should be inspected prior to each use. Replace worn or deteriorated parts with new parts.
