[0002]
[Prior art]
A fire extinguisher for a gas station has been proposed by the present applicant as JP-A-59-134196. This fire extinguisher is equipped with a fire extinguishing nozzle on the island where the weighing machine is installed, facing the refueling area. The fire extinguishing nozzle is connected to a fire extinguishing agent cylinder via an on-off valve, and the on-off valve is automatically connected with a signal from the fire detector. I try to open it. Although the present invention is effective, the fire detector may make a false detection by using sunlight or a car light as a fire, or a small fire may not be judged as a fire. If a fire extinguisher is sprayed from the fire extinguishing nozzle due to an erroneous detection, the fire extinguisher is wasted, and it is expensive to restore the site to its original state. In addition, if a small fire is not determined to be a fire, fire extinguishing agent will be injected after the fire becomes large, causing serious damage. And if a fire becomes large, it cannot extinguish only with such a fire extinguishing apparatus, and there exists a possibility that the damage by a fire may spread to the whole gas station.
