A black powder or granular mixed with a tar or starch and water binder pressed into regular lumps or briquettes. Heats slowly and ignites in air especially if wet.
Special Hazards of Combustion Products: Incomplete combustion forms toxic carbon monoxide.
Explosions have occurred when liquid air contacts organic matter. A cracked tube of activated charcoal immersed in liquid air exploded violently [J. Sci. Inst. 5:24 1928]. Zinc chlorate and charcoal (or finely divided organic material) form mixtures that may ignite or explode. Ignition or explosion may be caused by friction, percussion, or shock [U.S. Army Ordnance Safety Manual 1951].
