Riot control agents decontamination

Riot-control agents—such as CS, CN, and CR—are solids. Edge-wood scientists felt that dissemination and decontamination would be simpler with a volatile liquid agent. Research led to the produc tlon and testing of l-methoxy-l,3,5-cycloheptatriene (CHT, EA 4923), a liquid substance of high volatility (Table 4-40) with physiologic effects typical of riot-control agents (e.g., lacrlmation, skin irrl tatlon, and mucous membrane irritation). 

Riot Control Agents Decontamination. Exposed persons should if possible move to fresh air, separate from fellow sufferers, face into the wind with eyes open and breathe deeply. Following exposure, clothing and individual equipment should be inspected for residue. If a residue is found, individuals should change and wash their clothing to protect themselves and other unmasked persons. 

Because riot-control agents are particulate in nature, exposures will require decontamination of victims and responders. Bleach solutions should not be used for decontamination, because they will make the symptoms and effects of the agents worse. Plain soap and water are the best decontamination solutions. Emergency decon can be performed using the water from hose lines. Clothing must be removed. This process will remove the majority of the agent particles off of the person. 

The effects of exposure to a riot control agent are usually short-lived (15-30 minutes) after the person has been removed from the source and decontaminated (cleaned off)-... 

Concerns about the possible use of chemical agents in acts of terrorism have increased in the decade since the nerve agent Sarin caused a mass casualty incident in the Tokyo subway system. Chemical warfare poisons include nerve agents, vesicants, cyanides, riot control agents, and pulmonary irritants. Presenting symptoms as well as the clinical circumstances may help identify the agent and lead to effeotive treatment as well as proper decontamination.
