A pyrotechnic charge detonates in a shower of sparks
Summary
A pyrotechnic charge detonates in a shower of sparks and starts the chemical reaction dispersing CS gas across a group of security forces and law enforcement personnel from the 173rd Security Forces Squadron and local law enforcement agencies at Kingsley Field, Ore. July 21, 2015. Although the effects of the gas are unpleasant it has no ill effects and is therefore used for riot control. (U.S. Air National Guard photo by Tech. Sgt. Jefferson Thompson/Released)
