What is the primary purpose of straight tip nozzles in firefighting?

The primary purpose of straight tip nozzles in firefighting is to create solid streams. When water is discharged through a straight tip nozzle, it maintains a tight, focused stream that allows for maximum reach and penetration. This solid stream is effective in delivering water to the fire, which is essential for extinguishing it efficiently. The concentrated force of the stream can also help overcome obstacles, penetrate deep into the fire, and reach multiple floors in a building.

In contrast, while other nozzle types may assist in cooling or dispersing water, the straight tip nozzle is specifically designed for delivering a powerful and uninterrupted stream of water, making it a critical tool for firefighters in aggressive fire suppression efforts. The other options do not accurately reflect the primary function of this type of nozzle.
