Abstract:

US Army mask confidence training is conducted using low temperature heat-assisted dispersal of encapsulated o-chlorobenzylidene malononitrile CS riot control agent. This study quantified the CS concentration and identified the CS thermal degradation products detected inside of an Army mask confidence chamber. Degradation products identified in the chamber were compared to those observed in a laboratory setting at temperatures ranging from 150-300 deg. C. The average surface temperature of the Army dispersal system was 257 deg. C and the daily average CS concentration ranged from 2.33 - 3.29 mgm3. There were 17 CS thermal degradation products identified in the chamber, fifteen of which were identified in the laboratory one at 150 deg. C and 15 at 300 deg. C. The two additional products detected in the chamber were likely due to molten CS dripping through air holes directly into the heat source. A better CS delivery system that contains the CS and maintains a temperature near 150 deg. C should create the desired CS concentration and hinder the formation of undesirable degradation products.
