put on the mask by yourself. If at all possible,
try to hold your breath until the mask is on; this
may be very difficult since blood agents strongly
stimulate respiration. If a persons breathing has
stopped, administer artificial ventilation.
EFFECTS OF VOMITING AGENTS.
Vomiting agents are used for harassment but may
be dispersed along with lethal chemical agents.
Vomiting agents alone cause temporary incapacita-
tion only. Vomiting effects last from about 30
minutes up to several hours, depending on the
concentration. Vomiting agents are invisible and
odorless. They attack the body through the nose
and mouth and irritate the eyes.
EFFECTS OF TEAR AGENTS. Tear agents
are used for their harassing effect. They have been
used extensively as riot control and chemical
defense training agents. Tear agents attack the
eyes and irritate or burn moist areas of the skin.
Effects are instantaneous but normally persist for
only a few minutes.
Table 7-9 shows the properties of blister,
blood, nerve, and choking chemical agents.
Personnel decontamination stations differ
somewhat from ship to ship, but the basic
requirements of the stations are the same. Each
decontamination station is divided into two parts:
(1) a contaminated or unclean section containing
a washing area and (2) a clean section. This
prevents recontamination of personnel and ship
locations. If possible, the unclean and clean
sections have separate access routes or entrances.
The decontamination station provides showers
with warm water (if possible); cleansing agents,
such as ear syringes and eye bath cups; hair and
nail clippers; scissors; surgeons hand soap;
towels; and brushes. Radiation instruments for
monitoring personnel and clothing and supplies
of clean clothing are also on hand at each station.
A decontamination (decon) station should
be about 8 feet by 9 feet. It should have
an entrance from the outside and an exit
into an uncontaminated area near the showers.
If exposed to contamination, you should use
proper decontamination procedures. Do not
remove your mask until a monitor tells you
it is safe to do so. In general, personnel
decontamination does not take priority over
urgent battle requirements, but it should be
accomplished as soon as possible. The following
is a list of decontamination procedures:
1. Remove rain gear and battle dress just out-
side the decon station. Place it in the trash cans,
bags, or other storage provided. Now you will be
monitored for contamination. If there is no
contamination, go to an uncontaminated space
through another route. If there is contamination,
go through the process described in paragraph 2
through 5 below.
2. Enter the first part of the decon station in
pairs. Use the buddy system to do gross decon
of masks and gloves with the M258A1 personnel
decon kits. Decon boots by immersing them in
the 2- by 2- by 6-inch pans filled with a 9 percent
high test hypochlorite (HTH) and water solution.
3. Move to the second part of the decon station
where attendants will cut away your smock and
help remove your trousers and boots. Place the
contaminated clothing in trash bags for disposal.
4. Move to the showers, soap and wash your
entire body thoroughly, and rinse well. Pay special
attention to fingernails, hairy parts of the body,
and hidden parts where contamination tends to
5. You are now ready to enter the clean part
of the ship where you will put on new clothing.
Before you enter the clean part, a monitor with
a long-range radiac will check to ensure that you
no longer carry contamination. Turn over your
DT-60 dosimeter to this monitor. The monitor will
take the readings and enter them in the log.You
will be told if you can remove your gas mask.
Mission-oriented protective posture (MOPP)
establishes levels of readiness. The MOPP is a
flexible system of protection against chemical
agents used in chemical warfare defense. MOPP
prescribes various types of protective clothing and
equipment for wear, depending on the tactical
mission, work-rate demand, and heat stress
conditions (actual or possible). There are four
