What is the recommended pressure for a standard fog nozzle?

The recommended pressure for a standard fog nozzle is typically around 100 psi. This pressure is optimal as it allows the nozzle to effectively atomize the water, creating a fine mist that can increase the surface area for heat absorption. This is crucial for extinguishing fires while also maximizing the reach and effectiveness of the water stream. Operating at this pressure helps balance the flow rate and the desired spray pattern, ensuring that the firefighter can deliver an efficient stream without sacrificing control or maneuverability.

In practice, adjustments may be made based on specific firefighting scenarios, but 100 psi serves as a reliable benchmark for most standard fog nozzles. Understanding the importance of maintaining this pressure can greatly enhance a firefighter's ability to manage various fire situations effectively.
