Abstract

In a fire extinguisher containing a halogenated hydrocarbon extinguishant, the improvement wherein said extinguishant comprises at least one of 2-bromo-1,1,1,2-tetrafluoroethane and 2-bromo-2-chloro-1,1,1-trifluoroethane. These compounds will eventually decompose in the atmosphere so as not to present a hazard to the ozone layer.
