MASK ASSEMBLY - COMPONENTS

Facepiece: Made of silicone rubber, it fits closely against your face to form a seal

Head Harness: Secures the mask to your face. Head pad, two forehead, two temple two cheek straps, head (donning) tab

Inlet Valve Body & Inlet Valve DiskAllows the filtered air to enter the mask and prevents moist exhaled air from entering the filter canister

7


Airflow Deflector : Directs the filtered, inhaled air over the eye lenses to help prevent fogging

Nosecup Valve Disks: Allows filtered air to enter the nose cup and prevents moist exhaled air from fogging the eye lenses in cold weather

Outlet Valve Disk: Allows exhaled air to exit the mask while preventing unfiltered air from entering the mask

8


Outlet Valve Cover: Protects the outlet valve from damage

Front and side Voicemitter: Transmits the Marine's voice outside of the mask

unarmed marines sit in shade• Two Marines unmask for 5 min• Observed for 10 min• Remainder of unit unmasks if no

symptoms were shown• Continue to observe first two Marines • Approximately 30 min• Check liquid contamination with m8 paper• Senior marine directs two unarmed

marines to move to shady area• Marines hold breath, keep eyes open and

break mask seal for 15 sec

39

• Observe marines for 10 min• If no symptoms appear, Marines unmask

for 5 min• Observe Marines for 10 min• If no symptoms, remainder unmask• Continue observation• Have first-aid treatment available for both

procedures• Notify higher headquarters after completed• If either unmasking procedure indicates

agent present, senior Marine needs to:– Move to a new area and retest– Continue mission and retest in one hour– Use collective protection if available

Step #4 • Remove overgarment and

overshoes– Limits agent spread/prevents

agent penetrationStep #5• Remove gloves

– Removes contaminated gloves and limits spread of contamination

Step #6• Put on overgarment



48

Step #7• Put on overboots and gloves
