An improved inflammable liquid safety tank comprising a double walled tank body with the tank walls being interconnected by support plates. An intermediate container is formed by the inner wall structure of the tank and is adapted to hold inflammable liquid. A pressurized gas bottle is threadably mounted to a sleeve secured to and extending into the intermediate container. The pressurized gas bottle is selectively connected to the intermediate container to pressurize liquid held in the intermediate container. The pressurized gas bottle also communicates with the tank to pressurize a foam, nonflammable fluid, or cleaning agent placed in the chamber or outer compartment defined by the outer wall structure of the intermediate container and the inner wall structure of the tank body so that the foam, fluid or agent will be expelled from the tank if the tank wall is accidentally punctured. The outer compartment is preferably pressurized at a lower pressure than the intermediate container. A conduit is connected to an inlet/discharge 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 flexible hose with an adjustable nozzle is mounted to the tank body for selective communication with either the outer compartment or the intermediate container so that the material contained within either of the containers can be selectively discharged from the nozzle.
