How do attack hoses differ from supply lines?

Attack hoses are specifically designed for firefighting operations, which often require them to operate at higher pressures to effectively deliver water to combat fires. This characteristic allows firefighters to direct water streams at significant force, enhancing their ability to extinguish flames. However, operating at higher pressures means there’s also a greater potential for friction loss as the water travels through the hose. This friction loss can affect the available pressure at the nozzle, which firefighters need to manage carefully during operations.

While flexibility and diameter are important attributes for hoses, they do not define the primary difference in function between attack hoses and supply lines. Supply lines, in contrast, are typically larger in diameter to facilitate the transport of large volumes of water from the water source to the pump, and they are designed to maintain lower pressure during operation. Understanding these distinctions helps firefighters make informed decisions about which type of hose to use in various scenarios, ensuring effective and efficient fire suppression.
