031-506-2002
OVERVIEW
LESSON DESCRIPTION:
In this lesson you will learn a description of lethal, incapacitating, and
miscellaneous chemical agents.
TERMINAL LEARNING OBJECTIVE:
ACTION:
Describe lethal,
incapacitating,
and
miscellaneous
CONDITION:
Given information and illustrations about various
chemical
agents,
including
their
properties,
physiological
effects,
and
uses;
the
protection
required
against
them;
and
their
detection
and
decontamination.
STANDARD:
Demonstrate competency of the task skills and knowledge
by responding to the multiple-choice test covering
various types of chemical agents, including their
properties,
physiological
effects,
and
uses;
the
protection required against them; and their detection
and decontamination.

INTRODUCTION
Nerve agents GB and VX and blister agents, HD, L, and CX are most likely to
be used in chemical operations.
While there are other nerve and blister
agents, these are the most likely to be employed. Nerve agents act on the
nervous systems or may interfere with breathing and cause convulsions,
paralysis, and death.
While different nerve agents differ in molecular
structure, all nerve agents have the same physiological action. They cause
an increase in acetylcholine throughout the body by interfering with the
vital enzyme cholinesterase. In general, the peripheral nervous system of
the body makes use of two chemicals
