Which type of hose is typically used for supplying water at higher pressures in firefighting?

The correct answer is supply hose. In firefighting, supply hoses are specifically designed to transport water from a water source, such as a hydrant or a water tank, to the pump on a fire apparatus. They are capable of handling high volumes of water under significant pressure, which is essential for effective firefighting operations.

Supply hoses are often larger in diameter compared to other types of hoses, allowing for more water to flow through them without significant pressure loss. This efficiency is crucial during firefighting situations where rapid access to a large amount of water is necessary to combat fires effectively.

While attack hoses are used to deliver water directly to the fire and may also be subject to high-pressure scenarios, their primary function is to manage the direct extinguishing efforts rather than just the supply of water. Soft suction hoses are typically utilized to draft water from static sources or connect to hydrants and are not considered as high-pressure supply lines. High-pressure hose, while it implies durability and strength, is not a standard term typically used within the context of firefighting supply operations. Therefore, supply hose is the most appropriate choice for this scenario.
