Which statement about fog nozzles is true?

• A. Fog nozzles are used only outdoors
• B. Fog nozzles always produce a solid stream
• C. Adjustable fog nozzles provide a wide fog pattern
• D. Fog nozzles cannot be adjusted

Answer: (C)

Fog nozzles are designed to spray water as a fine fog rather than a single solid stream, and the key feature is adjustability. An adjustable fog nozzle can be set to a wide fog pattern, which blankets a larger area quickly. In interior fires, that broad pattern helps absorb heat, cool the space, and push heat and smoke away from firefighters and access points, improving visibility and safety. That capability makes the statement about providing a wide fog pattern the best description. The other ideas don’t fit: fog nozzles are used indoors as well as outdoors, they don’t always produce a solid stream, and they can be adjusted.
