Fire Hose

Fire Hose

A fire hose is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine or a fire hydrant. Indoors, it can permanently attach to a building's standpipe or plumbing system.

The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa; 116 and 290 psi) while its bursting pressure can be up to 83 bar (8,300 kPa; 1,204 psi) After use, a fire hose is usually hung to dry, because standing water that remains in a hose for a long time can deteriorate the material and render it unreliable or unusable. Therefore, the typical fire station often has a high structure to accommoda the length of a hose for such preventative maintenance.

On occasion, fire hoses are used for crowd control (see also water cannon), including most notably by Bull Connor in the Birmingham campaign against protestors during the Civil Rights Movement in 1963
