The fire fighting apparatus is equipped with a tank containing an extinguishing agent, a pipeline to forward the extinguishing agent, and a device to spread the extinguishing agent, particularly a nozzle. The tank (10) is located in a lower space of the building; the pipeline to forward the extinguishing agent is ascending pipeline (15) fixed along the height of the building; there are pipe sections branching off the ascending pipeline (15) at specific heights; and there are local shut-off devices and tools to spread the extinguishing agent at the end of each pipe section. The tank (10) is equipped with a gas space and the extinguishing agent inside it is a foam composition comprising water, a foaming agent, and in the solution of these two, a non-combustible foaming and propellant gas diluted or emulgeated under overpressure. The ascending pipeline (15) is connected to the fluid space of the tank (10), with a main valve (12) between the tank (10) and the ascending pipeline (15), and/or a local valve in branch sections. |
