Which of the following is NOT an advantage of solid stream nozzles?

Solid stream nozzles are primarily designed to deliver a powerful, high-velocity water stream that can be very effective in various firefighting situations. One of the key advantages of solid stream nozzles is that they can create a concentrated and focused stream of water, which is essential for effective long-range firefighting. This focused stream enables the firefighter to effectively reach the target while minimizing the impact of wind and other environmental factors.

Additionally, solid stream nozzles can be highly effective in low visibility conditions, as the solid stream is less likely to disperse into fog or mist, allowing firefighters to see their target despite smoke or darkness. This makes them particularly valuable in structural firefighting and other challenging scenarios where visibility is compromised.

However, using foam with solid stream nozzles presents challenges. Solid streams typically do not mix with foam solutions as effectively as fog nozzles do. Fog nozzles create a fine mist that can incorporate foam, enhancing its effectiveness on certain types of fires, especially those involving flammable liquids. Therefore, while solid streams are advantageous for various reasons, their compatibility with foam is limited compared to other types of nozzles.
