A fire hose is a high-pressure hose that transports water or another fire retardant to extinguish a fire. It connects to a fire engine or a fire hydrant outside. It can be permanently attached to a building’s standpipe or plumbing system indoors. A fire hydrant system is a water supply system that delivers sufficient pressure and flows through pipes throughout a building to a network of strategically located valves for firefighting purposes. It can also be defined as an active fire fighting connection point that allows firefighters to access a water supply. A fire hydrant system is an important safety measure or emergency equipment in a building.
