Set 2--Lets firefighters and workers in the facility know about the presence of harassing agents
, riot control agents, and smoke in the facility.
(6) By the end of WWI, research and development (R&D) of CW resulted in classifying chemical agents into two broad categories--casualty agents and harassing agents. (7) Casualty agents, as the name implies, are defined as chemical agents that cause severe injury or death.
Harassing agents, commonly referred to today as nonlethal agents, are defined as chemical agents that produce a temporary disablement on an individual.
Initially, these chemical compounds served as harassing agents for crowd control, but as the war developed their use evolved into a much broader application.
