Abstract: The device of the present invention is located in a closed containment enclosure surrounding a storage bin and comprises a closed tank (28) positioned on the storage bin containing a liquid (26) and having a fireproof shield enclosing the tank and a liquid level control system for controlling the level of liquid in the tank with the tank (28) comprising at least one opening in communication with the closed container enclosure, and at least one internal chamber in direct communication with the storage bin via a flue pipe and at least one external chamber in direct communication with the containment enclosure via said at least one opening.

Abstract: The limitation device (10, 11) comprises: a flue pipe (46), an closed tank (28) containing a liquid (26), a fireproof shield (20), and a system for controlling the levels of liquid in said tank (80). The tank (28) comprises at least one internal chamber (54) in direct communication with a storage bin (4) via said flue pipe (46), and at least one external chamber (52) in direct communication with a containment enclosure (2) via at least one upper opening (36) of said tank (28). Application to the limitation of the ultimate consequences of a failure to bring under control a mass fire in a storage bin (4) implanted in a containment enclosure (2).
