Abstract
The Bureau of Mines studied toxic products produced by burning eight fire-resistant mine conveyor belts, a brattice cloth, and an electrical cable insulation obtained from laboratory-scale burning experiments under various air-flow conditions. Generally, co product concentrations for most materials were noticeably higher than the NO2 and hcl levels that were measured; also, no phosgene was detected. However, several of the fire resistant belt samples yielded hcl concentrations that were above the reported lethal level for 1/2- to 1-hour exposures, although these data were limted to flow conditions where air dilution effects were small; the belt materials that showed this behavior included samples of polyvinyl chloride, styrene butadiene, styrene butadiene blends, and a British neoprene which yielded the greatest amount of toxic vapor. In addition, some results are presented on the phosphoric acid concentrations that may be produced from the decomposition of ammonium dihydrogen phosphate when dispersed on a burning coalbed.
