Fire Hoses: One Of A Kind?

. Positive pressure hoses include the attack hose

, supply hose, relay hose, forestry hose, and booster hose.

Attack hose A flexible hose used to transfer water from the fire pumper to the nozzle. These hoses have a standard length of 50 feet and are designed to operate at pressures topping out at approximately 400 psi.

Supply and Relay Hoses Generally a large diameter hose used to move water from a far-off fire hydrant to the fire pumper, or to pass water from one pumper to another over a long distance. The average length of supply and relay hoses are 100 feet, and they are designed to operate at a maximum pressure of 300 psi.

Forestry Hose As the name suggests, forestry hoses are used to combat fires in heavily wooded areas, grass, or brush. These hoses are lightweight which allows firefighters to move it through rugged terrain. Forestry hoses are usually 100 feet long and operate at pressures up to 450 psi.

Booster hose A rubber covered, strong hose used in fighting small fires. Like the former two, this hose has a standard length of 100 feet, although it can operate at pressures up to 800 psi.

Each of these positive pressure hoses are used to irrigate fires by transferring water from a source (fire hydrant, fire pumper) to the fire. Negative pressure hoses, or suction hoses, are used to suck water from unpressurized sources -- usually a body of water (lakes or rivers). Acting like a vacuum, these hoses have a standard length on only 10 feet.

Fire hoses differ from all other hoses in that they are designed to be rolled flat when they are not in use. This minimizes the storage space and allows for a more effective fighting of fires. Creating these unique hoses is an intricate process that is complete only after certain fire hose testing is done on the product. The time that goes into producing fire hoses allows firefighters to be confident and self-assured when on the job.
