ABSTRACT:
Fires, particularly fires of flammable liquids, are extinguished by applying to the burning surface an extinguishing composition containing particles of a thermoplastic polymer, suitably a rubber. The polymer particles are arranged in association with a sufficient quantity of a chemical extinguishing agent to protect the polymer particles during transit through flame to the burning surface. Upon striking the surface of a flammable liquid the polymer dissolves therein causing the liquid to gel and concentrating fire extinguishing agents on the liquid surface thus securing the liquid against reignition.
