Abstract
Fire-extinguishing compositions of low ozone depletion potential comprise dry particles of fire-extinguishing agents dispersed in a gel of liquified volatile perfluorocarbons, chlorofluorocarbons or hydrofluorocarbons. The dry particles are compatibilized with the carrier gel by the presence of a surfactant system composed of a non-ionic surfactant, a film forming fluorocarbon surfactant and a phosphorus containing antiflocculent.
