Release of CS 2 and/or H 2 S caused by friction is demonstrated on two N‐heterocyclic compounds carrying S‐atom containing substituents. Because of the generation of electrostatic charge and creeping discharge, simultaneously brought about by friction, ignition and possible explosion of the released gaseous products of decomposition could occur. The tested compounds proved not to be sensitive to impact. Nonetheless, fire and explosion hazard of dusts must not be judged by their sensitivity to impact only. It is necessary to test their sensitivity to friction as well.
