1 LT. 1.1 PROTECTIVE MASK AND CLOTHING (1-1 page 1)
2 Enabling objectives 1.1 Inspect individual protective mask. 1.2 Perform the five levels of mission-oriented protective posture.1.3 Describe the procedures for relieving oneself in a contaminated environment.
3 MCU-2/P MASK Sizes are : small medium large Identified by a raised letter on facepiece.

7 CANISTER (page 4) Canisters are packaged in sealed containers and have a shelf life of five years from dateof manufacture.Extensions are based on surveillance testresults.Canisters not effective against ammonia,carbon monoxide, carbon dioxide,commercial fuel gases, nitrous fumes,or sulfur dioxide
8 CANISTER SHOULD BE CHANGED WHEN: Clear indication chemical/biological agents is imminent and MOPP level III is set by Commanding OfficerThirty days after exposureImmediately after exposure to blood agents
9 CANISTER SHOULD BE CHANGED WHEN: cont. Evidence of mechanical damage.Immersed in water ,becoming wet in any manner.Excessive breathing resistance.Exposure to oily smoke.
10 ACCESSORIES (pages 5 and 6) CarrierOutsertsWater proofing bag
11 CARRIER (page 5) The mask should be stored in a ready condition inside themask carrier.May be worn in anyof these three positions.Web Belt carry.
15 OUTSERTSProtects the mask while stored in the mask 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.
16 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 bagPut the mask in the bagGather open endSqueeze bagTwist gathered end of bag tightly, fold twisted part backUse a rubber band, secure endPlace bag in carrierClose carrier flap
17 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.
18 ADDITIONAL ACCESSORIES Combat Spectacles (MAG 1)M-1 Canteen Cap
19 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 buckleReverse head harnessPull head harness, quick don tabTighten temple strapsHeadpad centered
20 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.
21 MASK FITTING PROCEDURES Chin strap tightenForehead strap tightenShake head side to side and up and down retighten if necessary.Install canisterTest drinking tube
22 NEGATIVE PRESSURE CHECK (page 8) Press palm over canister, breathe in lightly until resistance is felt. Hold breath for five to ten seconds.
23 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.
24 NEGATIVE PRESSURE CHECK (page 8) If outlet valve disc should become lodged, follow procedures below.Hold breath and close eyesHold facepiece firmly against face, pull down and out on outlet valve cover to expose discDislodge disc by lightly rubbing in a circular motion.
25 NEGATIVE PRESSURE CHECK Clear mask by exhalingConduct negative pressure checkOpen eyes and breath normallyReplace outlet valve cover
26 LEAK CHECKSYou 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.
27 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.
28 DONNING PROCEDURES (page 9) With suspected presence ofcontamination, don your maskimmediately before taking anotherbreath.You must presume the following prior to donning the maskeyeglasses or contact lenses removedmask leak checked and ready for donningprocedures
29 DONNING PROCEDURES Stop breathing Close eyes tightly Remove headgear Open carrier and remove maskDon mask using the quick don pull tabTighten neck strapsExpel air that has been held in the lungsCheck seal by covering canister opening and inhaling
30 DONNING PROCEDURES Open eyes and resume normal breathing Check seal by coveringcanister opening and inhalingExpel air that has been heldin the lungsDon mask using thequick don pull tabSecure hood, don headgearStop breathingClose carrierClose eyes tightlyOpen carrier and remove maskRemove headgearTighten neck straps
31 DOFFING PROCEDURES (page 9) For uncontaminated environment are as follows :Loosen mask neck strapsUnfasten and lower hoodRemove headgearRemove maskReverse head harness, shake or wipe any moisture from inside mask.Stow mask in carrier
32 DOFFING PROCEDURES For a Contaminated or Unknown Environment: With a M256A1 kit (15 min)Without a M256A1 kit
33 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 KitWithout M256A1 Chemical Agent Detector Kit4
34 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.5
35 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.6
36 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.7
37 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.8
38 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.10
39 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.11
40 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.12
41 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.13
42 CHEMICAL PROTECTIVE ENSEMBLE (Saratoga Suit) (Page 11) Individual protective action should be an immediate concern when personnel are under chemical, biological, and radiological attack.
43 CHEMICAL PROTECTIVE ENSEMBLE (page 11) The Saratoga Suit is a camouflage over garment consisting of a coat and trousers. Normally worn over uniform, in high temps, may be worn over underwear.The suit protects against chemical agent vapors, liquid droplets, biological agents, toxins and radioactive alpha particles.Contact with POL’s will significantly degrade protection provided by suit.Contaminated environment, provides 24 hours of protection.Can be worn for 30 consecutive days and may be laundered up to 10 times within those 30 days.
