Fire Hose Pipe

A fire hose pipe or a firehose is a high-pressure hose that carries foam or water within it to extinguish the fire. It can be attached to a fire engine or a fire hydrant outdoors and indoors, and can be attached to a building's plumbing system permanently. Fire hoses are commonly used for crowd control like water cannons. The hose is essentially the most basic piece of fire fighting equipment.

Firstly, turn on the stop valve and then run out the hose as much is required.
Secondly, turn the water on at the nozzle and direct the steam to the firebase.
Thirdly, you must ensure to leave the egress path between you and the nearest egress route.
