Riot control agents severe effect

CR is a potent peripheral sensory Irritant of low toxicity by the usual routes of administration.3 It appears safer than CS, which replaced CN and DM in turn as riot-control agent because of greater effectiveness and lower toxicity. Table 4-20 shows comparative toxi-citles of these compounds in several species.2... 

OSHA PEL TWA 0.05 ppm ACGIH TLV TWA 0.05 ppm Not Classifiable as a Human Carcinogen DOT CLASSIFICATION 6.1 Label Poison SAFETY PROFILE A human poison by inhalation. An experimental poison by ingestion, inhalation, intraperitoneal, and intravenous routes. Human systemic effects by inhalation lachrymation, conjunctiva irritation, and unspecified eye effects, cough, and dyspnea. A severe eye and moderate skin irritant. Questionable carcinogen with experimental neoplastigenic data by skin contact. A riot control agent. When heated to decomposition it emits toxic fumes of Cr. See also KETONES. 

This class of compounds is unique among the riot control agents because the effects do not appear immediately on exposure or seconds afterwards, but rather several minutes later. 

Two characteristics make this class of compounds unique among the riot control agents. The first is that the effects do not appear immediately on exposure or seconds afterwards, but several minutes later. In the absence of symptoms, a soldier will not mask immediately by the time he masks, he will have absorbed a significant amount. The effects may then cause him to unmask. 

Long-lasting exposure or exposure to a large dose of riot control agent, especially in a closed setting, may cause severe effects such as the following ...
