A smooth bore nozzle is recommended for high-pressure applications due to its design, which allows for the creation of a solid stream of water. This type of nozzle minimizes turbulence and delivers water more efficiently over longer distances, making it especially effective for reaching targets in challenging environments. The straight flow path of a smooth bore nozzle enables the firefighter to utilize the full pressure available from the hose, maximizing reach and penetration of the water stream.

In high-pressure situations, the priority is often to deliver a concentrated and powerful stream of water to suppress the fire effectively. Smooth bore nozzles excel at this, as they provide greater water velocity and less spray, ensuring that the water reaches its intended target without wasting energy on dispersion. This efficiency is crucial when dealing with intense fires requiring a strong, direct attack.

Other types of nozzles may not perform as effectively in high-pressure scenarios. For example, fog nozzles work by breaking up the water into a mist or spray, which can be useful in certain situations, but does not deliver the same forceful impact as a solid stream. Air-aspirating nozzles create additional bubbles for enhanced foam effectiveness in certain firefighting foams, but they also do not provide the same focused pressure treatment as a
