Extinguishing Media: Combustible solid. Store in open or well ventilated areas (see Water, foam, carbon dioxide and dry chemical. Engineering Controls'). Store away from sources of strong heat or flame. Keep away from strong oxidising agents. Special Firefighting Procedures: The product contains a combustible thermoplastic which will Smoking should be prohibited during unloading of the product melt and drip when ignited and give off combustion products and in storage areas as good SAFETY practice which are toxic (see Hazardous Decomposition Products'.)

Equipment should be thoroughly decontaminated Non hazardous waste. POLYSTYRENE is stable when buried in after use. soil but is slowly degraded by sunlight. If feasible recycle. Can be used as a soil conditioner. Dispose of waste in an Hazardous Decomposition Products: approved landfill. Carbon monoxide and carbon dioxide are the major products of incomplete combustion. The toxic potency of combustion products is similar to wood.
