Definition Attack Attack hose is a fabric-covered, flexible hose used to bring water from the fire pumper to the nozzle. This hose ranges in nominal inside diameter from 1.5 to 3 in (38 to 76 mm) and is designed to operate at pressures up to about 400 psi (2,760 kPa). The standard length is 50 ft (15.24 m).

(Attack line) A use classification of a fire fighting hose connected to output of a pump or other pressure source (e.g., gravity). Fire hose used to apply water or other fire fighting agent directly to a fire or burning substance. Typically of 2 + 1 ⁄ 2 inches (64 mm) diameter or less in the United States. Historically 1.5 inch hose was the ...
Flexible suction hose, also known as a suction hose, is a specific type of rigid fire hose used in drafting operations. When using this technique, the fire engine draws water for fire fighting from an unpressurized supply, such as a portable water tank, pool, or other static water source, instead of drawing water from a pressurized water supply, such as a fire hydrant.
In such cases, it is necessary to asphyxiate the fire. This can be done in a variety of ways. Chemical products which react with the fuel can be used to stop the combustion. A layer of water-based fire retardant foam can be applied by the fire hose in order to separate the oxygen in the air from the fuel.
This effectively moves the water supply closer to the fire, and greatly extends the reach of the hand lines when the apparatus cannot be placed any closer to the fire structure. Hose pack: A hose pack is a backpack containing fire hose in a preconfigured arrangement, sometime completely made from fire hose without a bag.
Fire retardant dispersed aerially onto brush adjoining a firebreak to contain the Tumbleweed Fire in California, in July 2021. A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their ...
Testing fire hose for thermal resistance to interior heat conditions is not part of the annual testing criteria of fire service hose. Gerald Hughes, Battalion Chief (retired), Chicago FD Some fire district engines have experienced that CAFS-filled hoses have a higher incidence of clogging and decrease in pressure.
This method of storing hose is designed for rapid deployment of a hose line to attack a fire. In this manner, the hose is stored perpendicularly across the fire apparatus, usually above or adjacent to the pump panel, instead of the usual parallel storage in the rear. This allows the firefighter to pull the hose in the direction of the fire ...
