PROBLEM TO BE SOLVED: To provide fire extinguishing system capable of forming a gel layer, capable of inhibiting spread of fire for a long time, on the surface of an object to be protected from fire. SOLUTION: The fire extinguishing system is configured to eject a fire-spread preventing agent from a nozzle to the object to be protected from fire so as to coat the surface of the object with the gel layer of the liquid fire-spread preventing agent including water. The water includes bubbles. The fire-spread preventing agent includes a high water-absorbent resin or temperature-sensitive high water-absorbent resin. Inert gas or fluorine gas is included in the bubbles. COPYRIGHT: (C)2009,JPO&INPIT
