Releases may also occur from the use of this chemical in smoke and pyrotechnic devices. Hexachloroethane content of the smoke devices is about 44.5-46% of the total solid material. The smoke device bums, producing smoke which is mainly zinc chloride, but contains some hexachloroethane. It was estimated that about 0.3-5% of the mass of the reagents in the device is released to air as hexachloroethane in the smoke, assuming a 70% bum efficiency (Katz et al. 1980 Novak et al. 1987). On this basis, it was estimated that during 1982-1984, a maximum of about 6,683 kg (14,700 pounds) of hexachloroethane was released to the atmosphere at Fort Irwin, California, a major military training facility (Novak et al. 1987). Hexachloroethane in smoke (aerosol) was measured in a wind tunnel at concentrations ranging from 0.64-1.26 mg/m3 (average 0.89 mg/m3) (Cataldo et al. 1989). 

Figure 3.7 An anti-smoking device the cigarette is inserted into the wider end. Partially oxidized carbon monoxide combines chemically with oxygen inside the device after leaving the end of the cigarette but before entering the smoker s mouth the oxygen necessary to effect this oxidation enters the device through the small circular holes positioned along its length...

Since the late 1980s, there has been a proliferation of new potential reduced-exposure products (PREPs), promoted by the industry with the claims of reduced harm, in all the four categories that were summarized earlier (Stratton et al. 2001 Hatsukami et al. 2002, 2005). These include (a) modified tobacco products, such as several denicotinized brands and reduced TSNA emission cigarettes (b) chewing gum impregnated with tobacco (c) smokeless tobacco products with claimed reduced nitrosamine levels and (d) cigarette-like products (carbon-heated smoking devices).

The first special smoke device used on land during the w ar was the British smoke pot containing a mixture of pitch, tallow, black powder, and saltpeter, which w as introduced in July, 1915. The first large-scale smoke operation occurred during the attack of the Canadians against Messines Ridge on Sept. 20, 1915, where several thousand smoke shell...

Hexachloroethane is used as a solvent, in fireworks and smoke devices in explosives, in celluloid, as an insecticide, and as a rubber vulcanizing accelerator. Earlier it was used as an anthelmintic for livestock. 

There are still photographs of experimental ordnance, mines, other explosive devices, grenades, bombs, incendiary darts, sprayers, smoke devices, laboratories, and the tests. 

Pyrophoric articles include any device containing a chemical that spontaneously combusts, such as some pyrotechnics, smoke devices, explosives, etc. 

An example of such a situation involved an ignition mixture for a smoke device. The initial ignition composition consisted of the following ... 

While the TA (for terephthalic acid) smokes cannot match the HC smokes in obscuration on a pound-for-ponnd basis, it may well tnm ont to be the case that smoke devices for use in training will contain a low-toxicity composition like the TA smoke mixture, and the more highly obscuring HC smokes are reserved for use in true battlefield conditions.
