Chemical agents used in riot control and warfare

The development of riot control agents is reviewed with emphasis on the major factors influencing the selection and deployment of those agents in current use. Typical agents, irrespective of their chemical nature, cause unpleasant symptoms involving the eyes, skin, mouth, nose and respiratory tract. Ideally, these symptoms cause the sufferer to seek escape from exposure and resolve within 15-30 minutes after exposure has ceased. The medical management of casualties is discussed, with particular consideration of the problems likely to be referred to a Poison Control Centre.
