     M272 First Aid & Safety
                   WARNING

1. Avoid all bodily contact with kit chemicals.

2. Alkaline chemicals used in mustard test is
   extremely hazardous.
M272 Equipment Characteristics
 Purpose – portable, lightweight kit that will detect and
   identify harmful amounts of CW agents when
   present in raw or treated water.

 Capabilities & Features – detects cyanide, mustard,
   lewisite and nerve agents.
M272 Operator’s Control & Indicators

 General – indicators which the operator looks
  for in each of the four agent tests:

 1.   Nerve Agent Test
 2.   Lewisite Test
 3.   Cyanide Test
 4.   Mustard Test
        Nerve Agent Test
When NERVE AGENT is present in water,
 TEST PATCH STAYS WHITE.

When NO NERVE AGENT is present, WHITE
 TEST PATCH TURNS BLUE.
           Lewisite Test
When LEWISITE is present in water, WHITE
 BEADS turn YELLOW or BROWNISH.

When NO LEWISITE is present, BEADS stay
 WHITE.
   Cyanide & Mustard Tests
When CYANIDE is present in water, WHITE BEADS in
 RED band tube TURN BLUE.

When NO CYANIDE is present, BEADS STAY WHITE.

When MUSTARD is present in water, WHITE BEADS
 in BLUE band tube TURN PURPLE.

When NO MUSTARD is present, BEADS STAY
 WHITE.
PMed Checks & Services (PMCS)
 General – before you operate, always keep in
  mind the WARNINGS and CAUTIONS.

 After you operate, be sure to do your After
   Operation (A) PMCS.
Operation Under Usual Conditions
                      WARNING
 •   Avoid all bodily contact with kit chemicals
 •   During CW alert or CW agent work, wear
     MOPP Level 4 PPE
 •   Do not use kit if you cannot see the colours
     correctly
 •   Do not use outdated kit for testing
Assembly & Preparation for Use
(1)   Unpack Kit
(2)   Locate Kit
(3)   Do Before Operation (B) PMCS while
      setting up Kit
(4)   Review Kit Instructions
(5)   Assemble Other Items
   Prepare Alkaline Solution
                  WARNING
Alkaline chemical used in the mustard test is
  extremely hazardous. One drop of this liquid
  accidentally splashed into the eye can cause
  permanent vision loss even if immediate first
  aid is applied.
      Operating Procedure
In each test you will check test water
  temperature. If it is less than 50F (10C),
  refer to “Operation Under Unusual
  Conditions”, for differences in test
  procedures.
Your kit instruction card also contains this
  information for testing with cold water
          Test 1 - Lewisite
When TEST 2 – NERVE AGENT is done, remove blue
 band tube from stopper assembly. Compare colour
 of beads with Lewisite Test Colours on instruction
 card:

• YELLOW or BROWNISH beads means DANGER
  = LEWISITE

• ALL WHITE beads means SAFE = No LEWISITE
       Test 2 – Nerve Agent
Read nerve agent test results carefully. In this test,
  NO COLOUR CHANGE on the white patch means
  agent is present.
Compare colours of patch on end with clipped corners
  with Nerve Agent Test Colours on instruction card:

• WHITE patch means DANGER – NERVE AGENT

• BLUE patch, MATCHING or BLUER than test
  colours, means SAFE – No NERVE AGENT
         Test 3 - Cyanide
• BLUE beads mean DANGER – CYANIDE

• ALL WHITE beads mean SAFE – No
  CYANIDE

Note: Yellow beads in blue band tube will not
 interfere with mustard test.
        Test 4 - Mustard
IGNORE any TAN colour

• PURPLE beads mean DANGER – Mustard

• ALL WHITE (or TAN) beads mean SAFE –
  No Mustard
Operation In Unusual Conditions
 COLD 32-50F (0-10C)

 HOT 105-125F (41-52C)

 FREEZING Below 32F (0C), Wind, Rain, or
  Snow
      NBC De-contamination
1. Vapour exposure
2. Droplet exposure:
  –   Overpacked kits
  –   Closed kits
  –   Open kits
  –   Simulant contamination
Prep Trg Simulant Test Water
GENERAL: Test water having a known
 simulant agent is used for operator training
 to practice water tests which give colours like
 the real CW agent.

However, DO NOT use simulants to field check
 kit reliability.
   Prep Simulant Test Water
Test water for each simulant agent is prepared
  as follows:
