Abstract: To provide a fire extinguisher capable of preventing in advance, a situation in which serious damage is caused, and executing initial fire extinction before a fire spreads so as to cope with a situation that in a mountain fire and a forest fire that are naturally generated, remote fire extinction is executed by using a helicopter and a fire engine, but starting of fire extinction is delayed and a fire fighting activity is started in a state that damage has spread.SOLUTION: Several water tanks (tank 1) for putting rain water 2 are installed beforehand in an especially important forest and a place where a fire fighting activity is expected to be difficult. Holes for discharging fire extinction water are formed on a side face of the water tank, and the holes are covered with metal lids that melt at a low temperature. The lids are closed at a normal temperature, but the lids 5 formed of low-temperature melting metal melt when a fire occurs in the periphery, and the temperature rises so that the rain water in the water tank is ejected through the holes 4 for discharging fire extinction water, and initial fire extinction in the periphery is carried out in an unmanned manner. That is, the fire extinguisher is a device that can prevent in advance, a situation in which serious damage is caused, which can interlock with a fire alarm as well.SELECTED DRAWING: Figure 2
