f. Rate and depth of breathing of the individual at time of exposure.
g. Amount of physical exertion of the individual at time of exposure.
h. Rate of detoxification, especially if exposure was long.
tabulation purposes, such variables are ignored, and the Ct values are
assumed to measure the amount of chemical agent received by an individual
breathing at a normal rate in a temperature climate with average humidity.
These values provide a basis of comparison for the chemical agent.
15. Harassing Concentration.
A concentration of a chemical agent which
requires masking or other protective measures. Such concentrations may be
Can be subdivided into two levels of identification
a. Definitive identification is the determination of the exact identity
b. Classification is the determination that a compound is a member of a
class of substances without knowledge of the exact identity of the compound.
17. Lethal Chemical Agent. An agent that may be used effectively in field
concentrations to produce death.
2-PAM Chloride (trade name Protopam Chloride or Pralidoxime
Chloride) used in treatment of nerve agent poisoning by some, but not all,
cholinesterase inhibitors (nerve agents).
Unlike Atropine, it acts by
reactivating the inhibited enzyme of the skeletal muscles as well as the
parasympathetic (glands and intestinal tract) sites, and therefore relieves
the skeletal neuromuscular block which causes the paralysis associated with
