An improved gasoline safety tank and fire extinguisher comprising a tank body with interchangeable inlet and outlet fittings secured thereto, an intermediate container mounted in the tank for holding gasoline, and a carbon dioxide bottle mounted in the intermediate container. A conduit is connected to an inlet fitting and extends into the intermediate container adjacent the floor of the intermediate container and below the level of liquid placed in the intermediate container. A pressurized carbon dioxide bottle is selectively connected to the inlet fitting and adapted to discharge pressurized carbon dioxide gas into the intermediate container so that the gas bubbles up through the liquid in the intermediate container into the top of the intermediate container simultaneously cooling the liquid and pressurizing the liquid in the intermediate container. The carbon dioxide bottle is connected to the tank to pressurize a foam placed in the space defined by the outer wall of the intermediate container and the inner wall of the tank body so that the foam will be expelled from the tank when the tank wall is punctured. A flexible hose is mounted to the tank body for connection to the carbon dioxide bottle so that carbon dioxide can be discharged from the bottle to fill tires and the like. Another flexible hose is selectively mounted on the opposite side of the tank and connected to a fitting having a connected conduit which extends into the space defined by the outer wall of the intermediate container and the inner wall of the tank. The foam pressurized by the carbon dioxide can selectively be discharged through the hose from the tank for fire extinguishing purposes.
