An apparatus for use in foam-type fire-fighting equipment in which a halogenated hydrocarbon (halogen), preferably trifluorobromomethane, CF3Br, is injected into the fire extinguishing agent to improve the efficiency thereof. In several embodiments in which a foam nozzle or a foam generator is employed, the halogen is metered at a prescribed rate into the foam or foam liquid to entrain halogen into the bubbles of the foam such that the bursting of the bubbles due to the effects of the fire release the halogen to act on the fire. In further embodiments, a foam for fighting fires is produced with a plain hose nozzle by injecting the halogen into the fire extinguishing agent, the bubbles of the foam having halogen entrained therein that is released when the foam is used to blanket a fire.
