Regarding fog nozzles, which statement is correct?

• A. Adjustable fog nozzles provide a wide fog pattern
• B. Fixed fog nozzles provide the widest pattern
• C. Fog nozzles cannot be adjusted
• D. Fog nozzles always produce a solid stream

Answer: (A)

Fog nozzle design lets you switch the spray from a narrow jet to a wide fog. This wide fog pattern is valuable in interior attacks because the fine spray blankets more area, absorbs heat more effectively, and improves visibility by protecting firefighters from radiant heat. An adjustable fog nozzle is built to provide that broader pattern when needed, which is why this option is the best description. Fixed fog nozzles stay on a single pattern and can’t adapt to conditions, and fog nozzles are designed to produce a fog spray rather than always a solid stream.
