CANISTER (page 4)
Canisters are packaged in sealed containers
and have a shelf life of five years from date
of manufacture.
Extensions are based on surveillance test
results.
Canisters not effective against ammonia,
carbon monoxide, carbon dioxide,
commercial fuel gases, nitrous fumes,
or sulfur dioxide
CANISTER SHOULD BE
CHANGED WHEN:
 Clear
indication chemical/biological
agents is imminent and MOPP level
III is set by Commanding Officer
 Thirty days after exposure
 Immediately after exposure to
blood agents
ACCESSORIES

carrier and also protect the lens from
chemical droplets and oil/petroleum products
when the mask is worn.
Issued in two sizes, small and medium/large.
WATER PROOFING BAG
(page 6)
Stowed in the carrier- used to protect the mask and
canister from moisture.
To use the water proofing bag, the following applies:




Remove the
waterproofing bag
Put the mask in the bag
Gather open end
Squeeze bag




Twist gathered end of
bag tightly, fold twisted
part back
Use a rubber band,
secure end
Place bag in carrier
Close carrier flap
WARNING!!!!
DO NOT STORE FOOD IN THE
WATERPROOF BAG. POSSIBLE
TOXIC EFFECTS COULD RESULT.
 DO NOT STORE YOUR MASK IN THE
WATERPROOF BAG FOR MORE
THAN 24 HOURS, MOISTURE AND
OFF-GASSING BUILD-UP IN THE BAG
MAY AFFECT THE CANISTER.

ADDITIONAL ACCESSORIES
Combat Spectacles (MAG 1)
 M-1 Canteen Cap

MASK FITTING PROCEDURES
(page 7 through 10)

A correctly adjusted mask is necessary
for the mask to fit properly.
•
•
•
•
•
•
Remove outsert and canister.
Loosen straps all but one inch from buckle
Reverse head harness
Pull head harness, quick don tab
Tighten temple straps
Headpad centered
MASK FITTING PROCEDURES

NOTE *** TIGHTEN ALL STRAPS
TOWARDS THE REAR OF YOUR HEAD.
 WARNING
!!!!! DO NOT
OVERTIGHTEN STRAPS, THIS
MAY CAUSE DISTORTION OF
MASK, CAUSING LEAKS.
MASK FITTING PROCEDURES
Chin strap tighten
 Forehead strap tighten
 Shake head side to side and up and
down retighten if necessary.
 Install canister
 Test drinking tube

NEGATIVE PRESSURE CHECK
(page 8)
 Press
palm over canister, breathe
in lightly until resistance is felt.
Hold breath for five to ten seconds.
WARNINGS!!!!!


DO NOT HOLD THE MASK BY CANISTER.
A CANISTER WHICH HAS NOT BEEN
SEATED PROPERLY IS THE MOST
COMMON CAUSE OF LEAKING MASK.
COLLAPSING THE LENS WHILE
PERFORMING NEGATIVE PRESSURE
CHECK MAY UNSEAT THE OUTLET VALVE
DISC AND CAUSE IT TO BECOME
LODGED IN THE OUTLET VALVE BODY.
NEGATIVE PRESSURE CHECK
(page 8)

If outlet valve disc should become
lodged, follow procedures below.
• Hold breath and close eyes
• Hold facepiece firmly against face, pull
down and out on outlet valve cover to
expose disc
• Dislodge disc by lightly rubbing in a
circular motion.
NEGATIVE PRESSURE CHECK
•
•
•
•
Clear mask by exhaling
Conduct negative pressure check
Open eyes and breath normally
Replace outlet valve cover
LEAK CHECKS
You must check the mask for leaks
when it is fitted, each time you put it on
and when you change canisters.
 Install canister before performing leak
checks.

DRINKING TUBE LEAK CHECK
(page 8)

To perform a leak check the following
procedures should be used.
• Test drinking tube-blow into, until
resistance is felt.
DONNING PROCEDURES

DOFFING PROCEDURES
For a Contaminated or Unknown
Environment:
With a M256A1 kit (15 min)
Without a M256A1 kit
DOFFING
PROCEDURES
For
a Contaminated or Unknown
Environment:
• Should be conducted as soon as
possible to alleviate soldiers’
encapsulation and restore their
combat potential.
• Two Unmasking Procedures:
— With M256A1 Chemical Agent
Detector Kit
— Without M256A1 Chemical Agent
Detector Kit
Overview of Unmasking
Procedures (cont.)
• Selected soldiers should be
disarmed before they unmask.
• Should be conducted in shade.
Bright, direct sunlight can cause
pupils in the eyes to constrict, giving
false signs of nerve agent exposure.
Unmasking with the M256A1
Chemical Agent Detector Kit
(1)
Senior person present selects one or
two soldiers to unmask after permission
is received from higher headquarters.
(2)
Conduct unmasking procedures in
shade.
(3)
Use M256A1 Chemical Agent
Detector Kit to test for chemical agents.
Use M8 Paper to check for liquid
contamination.
NOTE:
Continue only if both tests come
up negative.
Unmasking with the M256A1 Chemical
Agent Detector Kit (cont.)
(4)Direct
at least two soldiers to
unmask for 5 minutes and then don,
seal, and clear masks.
(5)Observe these soldiers for 10
minutes for symptoms.
(6)If no symptoms appear, direct all
soldiers to unmask.
Unmasking with the M256A1 Chemical
Agent Detector Kit (cont.)
(7)Check
soldiers for delayed
symptoms. Have first aid treatment
available.
(8)Complete steps (1) through (7) in
sequence.
NOTE: This entire procedure will take
approximately 15 minutes.
Unmasking without M256A1
Chemical Agent Detector Kit
(1)
Senior person present selects one or
two soldiers to unmask after permission is
received from higher headquarters.
(2)
Conduct unmasking in the shade.
(3)
Use M8 paper to check for possible
liquid contamination.
NOTE:
Continue unmasking procedures
only if test is negative.
Unmasking without M256A1 Chemical
Agent Detector Kit (cont.)
(4)
Select one or two soldiers to take a
deep breath and break the seals of their
masks, while keeping their eyes open for 15
seconds; then reseal and clear their masks.
(5)
Observe them for 10 minutes for
symptoms.
(6)
If no symptoms appear, direct these
soldiers to break the seals of their masks,
take two or three breaths, and then reseal
and clear their masks.
Unmasking without M256A1 Chemical
Agent Detector Kit (cont.)
(7)Observe
them for 10 more
minutes for symptoms.
(8)If no symptoms appear, direct
these soldiers to unmask for 5
minutes and then don, seal, and clear
their masks.
(9)Observe them for 10 minutes for
symptoms.
Unmasking without M256A1
Chemical Agent Detector Kit (cont.)
(10)
If no symptoms appear, direct
all soldiers to unmask.
(11) Check soldiers for delayed
symptoms and have first aid available.
(12) Complete steps (1) through (11)
in sequence.
NOTE: This entire procedure will
take approximately 35 minutes.
