Abstract

Fire extinguishing compositions and methods for extinguishing, controlling, or preventing fires are described wherein the extinguishing agent is a fluorinated ketone having up to two hydrogen atoms, alone, or in admixture with a co-extinguishing agent selected from hydrofluorocarbons, hydrochlorofluorocarbons, perfluorocarbons, perfluoropolyethers, hydrofluoroethers, hydrofluoropolyethers, chlorofluorocarbons, bromofluorocarbons, bromochlorofluorocarbons, iodofluorocarbons, hydrobromofluorocarbons, and mixtures thereof.
