ABSTRACT:
A system for extinguishing a fire in a tank filled with a flammable liquid product: a receptacle having an explosive charge within it and an extinguisher product that is dispersable over the flammable product to extinguish a fire there. Fuses that are ignited by contact with the fire communicate from outside the receptacle into the explosive charge. A flotation device below the receptacle, e.g. a lower bowl or a shell or flotation elements. The receptacle has an upper closing cover. The receptacle may be held beneath the surface of the flammable product by a weight to which the receptacle is moored by a rope that extends above the flammable product. The rope is separated by a fire of the flammable product, freeing the receptacle to float to the surface where the fuse to the explosive charge is ignited.
