On Fire Hazard of Polystyrene Foam Self-extinguishing Under the Conditions of Oxidizing Pyrolysis

Abstract

The clinical picture of damages during fire by combustion products of some constructing materials is not corresponds to often declare intoxication by carbon dioxide and sweet damp. On the basis of instrumental survey of thermal destruction's products of self-xtinguishing polystyrene foam samples was demonstrated that cause of people's mass destruction could be homogenous compounds, emerging under pyrolysis of Organohalogen compounds, which are added into polystyrene foam as fire retardants. There were presented results of study of self-extinguish polystyrene foampyrolysis process and products of its oxidizing destruction. There was manifested that pyrolysis of polystyrene foam, containingOrganohalogen fire retardants, inside the atmosphere of air is responsible for forming in products of high toxic Organohalogen compounds, one from which is cyanoformic chloride (phosgene gas). There were offered additives to polystyrene foam that allows suppress forming of toxic compounds under oxidizing pyrolysis.
