Nozzles at auxiliary hose stations shall be adjustable to what type of nozzle?

• A. Straight nozzles
• B. Fog nozzles
• C. Cone nozzles
• D. Adjustable nozzles

Answer: (B)

Fog nozzles are chosen because they offer adjustable spray patterns that can switch between a narrow, long-reaching stream and a wide, cooling fog. In a bulk oil storage setting, this flexibility lets responders blanket spills and hot surfaces with water to absorb heat, spread the water over a larger area, and suppress vapors, all while reducing the risk of igniting flammable aerosols. A straight stream would concentrate water in a single path with less cooling and coverage, and a cone or fixed pattern lacks the versatility needed for rapidly changing fire and spill conditions. The ability to tailor the spray with a fog nozzle makes auxiliary hose stations safer and more effective in mitigating oil fires.
