1. A fire extinguishing composition comprising a solid mixture of:
- a. 25 to 85 weight percent a thermally disseminable halogen-containing compound possessing fire extinguishing ability selected from the group consisting of hexachlorobenzene, hexabromobenzene, perchloropentacyclodecane, ar-dibromotoluene, 1,2,3,4-tetrachlorodibromobutane, decabromodiphenyl oxide, tribromopentyl alcohol, ar-tetrabromo-x-diethyl benzene, ar-tetrabromo-o-xylene, octachloronaphthalene, pentachlorotoluene, 1,2,4,5-tetrabromobenzene, 1,2,4,5-tetrachlorobenzene, polybrominated naphthalenes, dibromotetrafluoroctane, 1,2-dibromo-1,1-dichloroethane, 1,2-dibromo-3-chloropropane, and ar-dibromoethylbenzene;
b. 15 to 45 weight percent an oxidizer; and
c. 3 to 50 weight percent a binder fuel;
said halogen-containing compound being uniformly dispersed throughout the solid mixture.

Abstract
Disclosed is a novel fire extinguishing composition comprising a heat and gas producing pyrotechnic composition comprising a binder and an oxidizer, and having dispersed therein a halogen containing fire extinguishing agent. The pyrotechnic, when ignited, thermally disseminates the fire extinguishing agent onto the fire.

7. A method of extinguishing a fire comprising:
-
a. providing a solid mixture comprised of, by weight, i. 25 to 85 percent a thermally disseminable halogen-containing compound possessing fire extinguishing ability, ii. 15 to 45 percent an oxidizer, and iii. 3 to 50 percent a binder fuel, said oxidizer and binder fuel being selected and provided in proportions such that the temperature of the burning composition is sufficient to vaporize but not ignite or decompose said halogen-containing compound, b. thermally disseminating the halogen-containing compound by igniting said solid mixture, and c. distributing a fire extinguishing amount of the thermally disseminated halogen-containing compound over the fire area. - View Dependent Claims (8, 9, 10, 11, 12)
