Little data is available on oxidative degrative behavior of materials used in coal mines under truly dynamic conditions approximating the mine environment. Accordingly, tests were performed on: (a) polyvinyl chloride-containing materials; (b) neoprene compositions; (c) rigid foams (urethanes, isocyanates); (d) miscellaneous materials (including jute, fiber glass and polyethylene) using a stagnation burner arrangement. It was found that the chlorine-containing materials evolved hydrogen chloride very readily, its rate of evolution being strongly temperature dependent. Even at the high air flow rates employed, significant quantities of hydrogen chloride were detected. The fluorocarbon propellant and co2 were the main products found on decomposition of the foams, whereas among other products jute compositions liberated methyl chloride. The analyses were performed using mass spectrometry and infrared spectroscopy.
