(2) Detection Using the M256 Chemical Agent Detector Kit. Procedures
described in the following steps.
Remove one detector sampler from the kit.
Tear protective bag and remove sampler.
Perform steps 1 - 12 as described on the protective bag and
the kit instruction cards.
The nerve agent section of the sampler will remain
colorless or turn a peach color if a nerve agent such as VX
is present. Any shade of blue indicates the absence of VX.
Do not use an outdated sampler because it will give unreliable
As a minimum, you must wear the protective
mask and gloves when operating the M256 Chemical Agent Detector.
Decontamination of VX can be accomplished by
slurry, DS2, or hot, soapy water; M258-Series Kit; M280 Decontamination Kit,
Individual Equipment; or M291 Skin Decontamination Kit.
b. Nerve Agent (GA). Nerve agent Tabun (GA) is a brownish to colorless
liquid that gives off a colorless vapor.
It enters the body primarily
through the respiratory tract, but it is also highly toxic through the skin
and digestive tract. It is about 20 times more persistent than GB, but not
as stable in storage.
(1) Detection. Detection methods for GA can be accomplished by any
of the following detection equipment: M8 and M9 Detector Paper; M256A1
Monitor (CAM); and the M18A2 Detector Kit.
Decontamination can be accomplished by using
bleach slurry, DS-2, steam, ammonia, M258A1 and M291 Skin Decontamination
Kits and the M280 Decontamination Kit.
c. Nerve Agent (GB). Nerve agent GB is colorless, odorless liquid. In
an impure form, it may have a slight fruity odor. GB is used as a quick-
acting casualty agent. Casualties
