A process for controlling or extinguishing fires comprises introducing to a fire or flame (e.g., by streaming or by flooding) a non-flammable extinguishment composition comprising at least one mono- or dialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluo

A process for controlling or extinguishing fires comprises introducing to a fire or flame (e.g., by streaming or by flooding) a non-flammable extinguishment composition comprising at least one mono- or dialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms in its perfluorinated portion and preferably having a boiling point in the range of from about 0.degree. C. to about 150.degree. C. The compounds exhibit good extinguishment capabilities while being environmentally acceptable.

[ What is claimed is:] [1.] A process for preventing fires or deflagration in an air-containing, enclosed area which contains combustible materials of the non-self-sustaining type comprising the step of introducing into said air-containing, enclosed area a non-flammable extinguishment composition which is essentially gaseous under use conditions and which comprises at least one mono- or dialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, said compound having a boiling point in the range of from about 0.degree. C. to about 150.degree. C. and optionally containing one or more additional catenary heteroatoms in its perfluorinated portion, and said composition being introduced and maintained in an amount sufficient to impart to the air in said enclosed area a heat capacity per mole of total oxygen present that will suppress combustion of combustible materials in said enclosed area.
