Military, correctional officer, and law enforcement personnel, are routinely exposed to 2-chlorobenzylidenemalononitrile CS during combat training, chemical protective mask confidence training, and riot control operations training. The public may be involuntarily exposed during rioting or civil disturbances. The potential exists for CS to form new compounds when dispersed by means of oxidizer-supported combustion of a chemical fuel from inside a canister. Research objectives were to identify CS-derived compounds that may be relevant to the preservation of health among those exposed, and to explore the effect of temperature on their formation. In addition to the need to identify these compounds and to understand their toxicity, knowledge of the temperature ranges associated with their formation is also important. If CS-derived compounds produced during heat-dispersion of CS canisters prove to be a public health hazard, alternative dispersion methods may be warranted.
