These are:

a. Rapid pulse rate - over 100.

b. A very dry mouth and throat.

c. Hot dry skin.

d. Enlarged pupils (opposite to nerve agent poisoning).

When providing first aid, casualty bags may be used to protect personnel who cannot wear the respirator as a result of injury or illness. Use the bag if a casualty may be exposed to a contaminated environment when in route to treatment.

Immediate Self Aid

After masking, if any symptoms of nerve agent poisoning become apparant (see Task 9) give yourself one CP injection. If symptoms persist further injections at 15 minute intervals, up to a total of three, are to be made. Immediately seek medical aid. This drill has priority over everything but masking.

Remove the plastic cover from the CP by tearing at the tabs formed by the V at the safety cap end.

Pull the grey safety cap off the CP

Place the black 'snout' of the CP against the outer thigh muscle midway between knee and hip, making sure that it is clear of anything in the trouser pocket, and press hard until the injector functions. Count to 10 slowly then withdraw. Record time CP administered.

Replace old CP in the haversack, bending the needle on any hard surface to make it fit.

◉ If you use any CP, report this to your Commander and seek medical advice at the earliest opportunity.


a. Practise the immediate self aid drill; a training version of the CP is available.

b. Learn the symptoms of Atropine poisoning.


You have to be able to:

a. Put the correct NBC IPE on yourself and casualty.

b. Decide which group of agents has caused the casualty.

c. Apply the correct first aid for that group of agents.

Study Notes

Quick, appropriate first aid will improve a chemical casualty's chances of survival.

First you must protect yourself and the casualty from further agent by masking unless you are quite sure that the vapour has dispersed. If your position has just suffered a chemical attack you should be able to deduce the agent from information given by 3 colour detector paper (nerve or blister), LCAD/MCAD, CAM (nerve or blister), RVD (nerve, blister or unknown agent). If this is the case start treatment without delay. If the agent type is unknown you must deduce from which group of agents the casualty is suffering: nerve, choking, blood, blister or mental incapacitant. Each group requires different treatment.

Ensure the casualty has a clear unobstructed airway and has a properly sealed mask.

Checks Before Treating a Chemical Casualty

Deciding from Symptoms which Agent is Poisoning the Casualty

If you are not sure which group of agents has caused the casualty, start by looking into the eyes to see if pupils are:




Then follow the appropriate procedure given below:

Pupils Pinpointed

Look for:

(1) Running nose.

(2) Saliva or drooling at the mouth.

(3) Difficulty in breathing (wheezing).
