ABSTRACT:
A gasoline safety tank system utilizing at least one safety tank, each safety tank comprising a tank body with interchangeable inlet and outlet fittings secured to the tank body, 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 the 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 also 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 so that the foam will be expelled from the tank when the tank wall is punctured.
