The primary purpose of a nozzle in firefighting is to direct water flow. Nozzles are specifically designed to shape and focus the stream of water being discharged from a hose, allowing firefighters to deliver water effectively to the target area. This capability is crucial in combating fires, as it enables the operator to adjust the pattern and reach of the water stream based on the situation. For example, changing the nozzle setting can create a narrow stream for distance or a wide spray for coverage over a larger area.

Directing water flow is essential for cooling hot spots, suppressing flames, and protecting personnel and property within the fire's vicinity. It ensures that water is applied precisely where it is needed most, enhancing the efficiency of firefighting operations. The nozzle not only affects the speed and pressure of the water being utilized but also plays a pivotal role in the overall fire attack strategy.
