Which type of stream is best used for fire suppression?

In the context of fire suppression, a fog stream is highly effective because it combines several beneficial properties. When water is dispersed into tiny droplets, it not only covers a larger surface area but also enhances cooling through a greater evaporation rate. The small droplets can absorb more heat quickly, making it easier to extinguish flames.

Furthermore, fog streams create a barrier of steam that can help protect firefighters by limiting the heat exposure from the fire. This steam also displaces some portions of the oxygen available to the fire, which helps to reduce the fire's intensity. Additionally, fog streams are less prone to creating a strong wind effect that can spread the fire, which can happen with solid streams or high-pressure streams.

While solid streams are powerful for penetrating deep into a fire, they may not cool the fire as effectively as a fog stream does, nor do they benefit from the thermal protection provided by steam. Water mist systems also have their applications but may not be as versatile for all fire types as fog streams. High-pressure streams can be useful in certain scenarios but might also lead to increased risks of fire spread due to their velocity. Consequently, fog streams balance effective cooling, safety for firefighters, and the ability to control fire spread, making them a preferred choice for many
