Contamination Markers

Protect Yourself Protect yourself from CB contamination using your assigned protective mask without fastening the hood. The mask gives immediate protection against inhalation of agent vapors. Do not fasten the hood. Go to the next step immediately.

Give the Alarm Yell “GAS” Give the appropriate hand-arm signal

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

Decontaminate Skin Decontaminate exposed skin using the individual Decontaminating kit as necessary.

Assume MOPP 4. 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, and then secure the overgarment to increase protection. d. Put on the overboots. Combat boots provide protection but should be covered because they absorb chemicals.
