031-503-1019 (SL1) - React to Chemical or Biological Hazard/Attack

Standards: React to a chemical or biological hazard or attack without becoming a casualty. Identify chemical contamination markers with 100 percent accuracy, and notify supervisor. Start steps to decontaminate yourself within 1 minute of finding chemical contamination. Decontaminate your individual equipment after you completely decontaminate yourself.

Conditions: You are given mission-oriented protective posture (MOPP)
gear, a protective mask, individual
decontaminating kits, and a tactical
environment in which CB weapons have been or
may be used by the enemy. 
You are in MOPP1, and one or more of
the following automatic masking criteria
happens:

  1. A
    chemical alarm sounds.

  2. A
    positive reading is obtained on detector
    paper.

  3. Individuals
    exhibit symptoms of CB agent poisoning.

  4. You
    observe a contamination marker.

  5. Your
    supervisor tells you to mask.

  6. You
    see personnel wearing protective masks.

  7. You
    observe other signs of a possible CB
    attack.

Standards:
React to a chemical or biological hazard or
attack without becoming a casualty. Identify
chemical contamination markers with 100
percent accuracy, and notify supervisor.
Start steps to decontaminate yourself within
1 minute of finding chemical contamination.
Decontaminate your individual equipment
after you completely decontaminate yourself.

Performance
Steps

1.   Identify the CB hazard automatic masking criteria.

a.
Don your protective mask
when there is a high probability of
a chemical attack, when–

(1) 
A chemical alarm
sounds.

(2) 
A positive reading is
obtained on detector paper.

(3) 
Individuals exhibit
symptoms of CB agent poisoning.

(4) 
You observe a
contamination marker.

(5) 
Your supervisor tells
you to mask.

(6) 
You see personnel
wearing protective masks.

(7) 
You observe other signs
of a possible CB attack.

b.
Respond to the
commander’s policy of automatic
masking.

Note.  Commanders
at all levels may establish a modified
policy when chemical weapons have been
employed by designating additional
events as automatic masking criteria.

2.   Protect yourself from CB contamination using your
assigned protective mask without
fastening the hood.

Note.  The mask
gives immediate protection against
inhalation of agent vapors. 
Do not fasten the hood. Go to
the next step immediately.

3.   Give the alarm.

a.
Yell "GAS."

b.
Give the appropriate
hand-and-arm signal.

4.   Take cover to reduce exposure, using whatever means
is readily available.

5.   Decontaminate exposed skin using the individual
decontaminating kit, as necessary.

6.   Assume MOPP4. 
Cover all your skin (your head
and shoulders are already protected by
the mask and the overgarment).

a.
Put on the gloves with
liners.

b.
Zip and fasten the
overgarment jacket.

c.
Secure the hood, then
secure the overgarment to increase
protection.

d.
Put on the overboots. 

Note.
Combat boots provide protection but
should be covered because they absorb
chemicals. 
It takes a long time to put on
the overboots, so put them on last in
an emergency.

7.   Decontaminate personal equipment using the
individual decontaminating kit as
necessary.

8.   Notify your supervisor of any CB hazard markers or
indicators.

9.   Continue the mission.

Note. After assuming
MOPP4 and performing all the tasks
according to the unit SOP perform the
following actions:
1. Use all means of CB detection to
check your surrounding area for the
presence of contamination.
2. Contact higher headquarters (HQ) if
no contamination is found or if you
determine the attack was non-CB.
3. Await further guidance. (Higher HQ
contacts all adjacent/attached units
to check the status of CB
contamination in their areas. If all
units report the absence of
contamination, the information is
reported up the chain of command.)
4. Annotate the above actions on your
duty log (Department of the Army [DA]
Form 1594).

Evaluation Preparation: 

Setup:  A good time to
evaluate this task is during a field
exercise when a variety of CB hazards can be
simulated. 
Select a site with adequate cover,
and ensure that soldiers are in MOPP1.

Brief
Soldier: 
Tell the soldier there will be an
encounter with simulated CB contamination
and/or a CB alarm will be given. 
The task is to recognize the hazard
and/or alarm and to take appropriate action
to protect himself and warn other soldiers
by giving the appropriate alarm. 

Performance
Measures

GO

NO
GO

1.   Identified the
CB hazard automatic masking criteria.

2.   Protected himself from CB contamination using his
assigned protective mask without
fastening the hood..

3.   Gave the alarm.

4.   Took cover to reduce exposure, using whatever means
was readily available.

5.   Decontaminated exposed skin using the individual
decontaminating kit as necessary.

6.   Assumed MOPP4. Covered all his skin.

7.   Decontaminated personal equipment using the
individual decontaminating kit as
necessary.

8.   Notified the supervisor of any CB hazard markers or
indicators.

9.   Continued the mission.

Evaluation
Guidance: 
Score the soldier GO if all
performance measures are passed. 
Score the soldier NO GO if any
performance measure is failed. 
If the soldier fails any performance
measure, show him what was done wrong how to
do it correctly.
