In windy conditions, what adjustment is recommended for master stream operation?

• A. Shut down the stream and wait for calmer conditions.
• B. Increase nozzle size beyond recommended.
• C. Ventilate the area to avoid wind.
• D. Under windy conditions, adjust position, pattern, and flow to counter wind.

Answer: (D)

Wind changes how a master stream behaves by bending, dispersing, and blowing the water off course, and it can also increase nozzle reaction. The best approach is to actively counter those effects by changing where you stand, how you discharge the stream, and how much water is flowing. Move to a position that helps the stream stay on target despite the wind, choose a pattern that’s more resistant to wind drift, and adjust the flow so you maintain control without overloading the nozzle or losing reach. This keeps the stream effective and safer for the crew and victims.

Shutting down the master stream isn’t practical in a windy outdoor environment, and increasing the nozzle size beyond what’s recommended isn’t safe or controllable. Ventilating the area isn’t a workable fix for wind at an exterior fire. The key is adapting position, pattern, and flow to counter the wind.
