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.
本文描述了灭火组合物和灭火、控制或预防火灾的方法,其中灭火剂包括单独的氟代环氧烷或与氢氟碳化物、氯氟碳化物、全氟化碳、全氟聚醚、氢氟醚、氢氟聚醚、氯氟碳化物、溴氟碳化物、溴氯氟碳化物、碘氟碳化物、氢溴氟碳化物、氟代酮、氢溴碳化物、氟代烯烃、氢氟烯烃、氟代砜、氟代乙烯醚和其混合物的共灭火剂混合使用。还描述了通过将这些组合物引入含空气的封闭区域并保持足够的组合物量以抑制该封闭区域可燃物的燃烧来预防或灭火的方法。
