A fire extinguishing agent includes an oxygen depleting agent, a heat removing endothermic agent, and a flame retarding agent. According to a preferred embodiment of the invention, the oxygen depleting agent is preferably a halon gas mixture of equal parts Halon 1211 and Halon 1301, the endothermic agent is preferably carbon dioxide, and the flame retarding agent preferably includes an aqueous solution of baking soda and a standard liquid flame retardant. The fire extinguishing agent, which may be provided in gas, liquid, or powder form, is preferably pressurized with nitrogen or another inert gas. According to a preferred aspect of the invention, the Halon 1211 and Halon 1301 are forced through a diesel fuel filter prior to entering the pressurized container. The filter removes and collects reactive chlorofluorocarbon constituents from the halon gases. The fire extinguishing agent extinguishes a fire, removes heat from the fire and material which was burning, and retards reignition of the fire. In addition, the removal of reactive chlorofluorocarbon constituents permits the extinguishing agent to be relatively environmentally friendly. The halon gases extinguish the flames by removing oxygen from the fire, the carbon dioxide removes heat from the fire, and the flame retardant agent provides a coating which prevents oxygen from interacting with the fire.
