a. Gasoline, chlorine, and pesticides are examples of
common toxic substances. They may exist as solids, liquids,
or gases depending upon temperature and pressure. Gasoline,
for example, is a vaporizable liquid; chlorine is a gas;
and Warfarin, a pesticide, is a solid. Some substances
are more injurious to the body than others when they are inhaled
or eaten or when they contact the skin or eyes. Whether they are
solids, liquids, or gases (vapors and aerosols included), they
may irritate, inflame, blister, burn, freeze, or destroy tissue
such as that associated with the respiratory tract or the eyes.
They may also be absorbed into the bloodstream, disturbing one
or several of the body's major functions.
b. You may come in contact with toxic substances in combat
or in everyday activities. Ordinarily, brief exposures to common
household toxic substances, such as disinfectants and bleach solutions,
do not cause injuries. Exposure to toxic chemical agents in warfare,
even for a few seconds, could result in death, injury, or incapacitation.
Remember that toxic substances employed by an enemy could persist
for hours or days. To survive and operate effectively in a toxic
environment, you must be prepared to protect yourself from the
effects of chemical agents and to provide first aid to yourself
and to others.
