When conducting the hand line nozzle test, what angle should the nozzle be tilted to?

Tilting the nozzle at a 30-degree angle during the hand line nozzle test is optimal for maximizing the effectiveness of the water spray while maintaining control during operation. This angle allows the water to be directed in a manner that achieves a good balance between vertical reach and coverage area on the fire.

At this angle, the stream can achieve an effective distance to penetrate the flames while also allowing the operator to manage the nozzle's reactionary forces effectively. A steeper angle, such as 45 or 60 degrees, might reduce the reach and effectiveness of the spray, while a shallower angle might not adequately cover the target area, thereby compromising firefighting efforts. The 30-degree tilt represents a compromise that facilitates a strong spray pattern while still allowing for a manageable operation of the nozzle, enabling better performance in firefighting scenarios.
