ROC'EM by Counter Assault OC10-4

Defensive chemical sprays usually contain one of three active ingredients: CN or CS (tear gases), or OC (pepper). CN is a lachrimatory agent, which causes severe tearing of the eyes. It also produces tightness in the chest and a burning sensation on exposed skin. CN is relatively easy to decontaminate, but it is not always effective on pain-resistant subjects, and it has little or no significant effect on animals. CS is an irritant that produces heavy tearing, coughing, nausea, and involuntary closure of the eyes. CS generally requires medical decontamination because it has been known to cause burns to the eyes. CS is also not effective in aerosols due to its low vapor pressure. OC is a natural, oily, resin-like substance derived from hot peppers, the same kind used in spicy foods. OC produces an almost immediate burning sensation of the skin and a burning, tearing, and swelling of the eyes. When inhaled, OC causes inflammation of the respiratory tract, resulting in swelling of the mucous membranes. These inflammatory and swelling effects are unavailable with CN and CS. In addition, the effects of OC are easy to treat. Treatment is accomplished by simply flushing the exposed area with large quantities of water. As soon as possible, the affected person should be removed from the contaminated area, placed in a  fresh-air environment, and told to place their head briefly under water while opening their eyes.
