Blood agents interfere with proper oxygen utilization in the body.
Hydrogen cyanide (AC) and cyanogen chloride (CK) are the primary
agents in this group.
a. Protective Measures. Your protective mask with a fresh
filter gives adequate protection against field concentrations
of blood agent vapor. The protective overgarment as well as the
mask are needed when exposed to liquid hydrogen cyanide.
b. Signs/Symptoms. During and immediately after exposure
to blood agents (depending on agent Concentration and length of
exposure), you may experience some or all of the following signs/symptoms:
- Eye irritation.
- Nose and throat irritation.
- Sudden stimulation of breathing.
- Nausea.
- Coughing.
- Tightness of chest.
- Headache.
- Unconsciousness.
c. First Aid Measures.
(1) Hydrogen cyanide. During any chemical attack, if
you get a sudden stimulation of breathing or notice an odor like
bitter almonds, PUT ON YOUR MASK IMMEDIATELY. Speed is absolutely
essential since this agent acts so rapidly that within a few seconds
its effects will make it impossible for individuals to put on
their mask by themselves. Stop breathing until the mask is
on, if at all possible. This may be very difficult since
the agent strongly stimulates respiration.
(2) Cyanogen chloride. PUT ON YOUR MASK IMMEDIATELY if
you experience any irritation of the eyes, nose, or throat.
d. Medical Assistance. If you suspect that you have been
exposed to blood agents, seek medical assistance immediately.
