What is the primary function of supply hoses in firefighting?

The primary function of supply hoses in firefighting is to move larger volumes of water. Supply hoses are specifically designed to transport water from a source, such as a hydrant, to a pump or directly to the firefighting apparatus. This capability allows firefighters to draw on substantial quantities of water needed to effectively combat large fires.

While supplying water to nozzles and providing access at fire scenes are essential functions related to firefighting operations, these tasks generally pertain to attack hoses or other types of lines used once the fire apparatus is on the scene. The efficient movement of larger volumes of water is critical for maintaining adequate pressure and flow rate, enabling firefighters to effectively suppress fires. This understanding is vital for effective firefighting strategies and for ensuring that sufficient water supply is maintained throughout the duration of the incident.
