    摘要: Fire extinguishing compositions and methods for extinguishing, controlling, or preventing fires are described wherein the extinguishing agent includes a fluorinated oxirane alone, or in admixture with a co-extinguishing agent selected from hydrofluorocarbons, hydrochlorofluorocarbons, perfluorocarbons, perfluoropolyethers, hydrofluoroethers, hydrofluoropolyethers, chlorofluorocarbons, bromofluorocarbons, bromochlorofluorocarbons, iodofluorocarbons, hydrobromofluorocarbons, fluorinated ketones, hydrobromocarbons, fluorinated olefins, hydrofluoroolefins, fluorinated sulfones, fluorinated vinylethers, and mixtures thereof. Also described are methods of preventing or extinguishing fires by introducing these compositions into an air-containing enclosed area and maintaining the composition in an amount sufficient to suppress combustion of combustible material in that enclosed area.
