Background Technology

[0003] A building refers to a structure constructed on the ground that forms a living space within where people can live.

[0004] In such buildings, various devices capable of enhancing human convenience are installed, and various electrical, telecommunications, and gas equipment are installed and utilized.

[0005] In this case, there are instances where fires occur in buildings constructed above ground due to malfunctions in various electrical or gas appliances used indoors, or due to the negligence of people living inside.

[0006] In such cases, indoor fires in buildings are extinguished using fire extinguishers capable of rapidly suppressing indoor fires or various firefighting equipment capable of spraying extinguishing water; however, if a fire originating in a building spreads, the fire in the building can be extinguished by spraying extinguishing water at the point of the fire using spray nozzles equipped in the building or spray nozzles capable of spraying extinguishing water, such as those on fire trucks.

[0007] For example, in the past, as in literature (1), a fire extinguishing facility capable of spraying fire extinguishing water to the point where a fire occurred has been proposed and used.

[0008] However, conventional firefighting facilities such as the one described in document (1) can suppress fires in buildings through firefighting water sprayed through a spray nozzle, but there was a problem that it was difficult to hold and use the spray nozzle due to the pressure of the firefighting water sprayed by non-skilled users, and thus it was difficult to efficiently suppress fires in buildings using the spray nozzle.
