What name is given to a large, permanently mounted nozzle used to deliver a heavy water stream from an engine?

• A. Deck gun
• B. Aerial monitor
• C. Fog nozzle
• D. Portable monitor

Answer: (A)

A deck gun is the large, fixed nozzle mounted on a fire engine that delivers a heavy water stream. It’s designed for high flow and long reach, staying in place on the engine to project water for large fires or to protect openings. An aerial monitor sits on an elevated, ladder-style apparatus and isn’t permanently mounted on the engine. A fog nozzle focuses on producing a light, dispersed spray for cooling and visibility rather than a heavy, sustained stream. A portable monitor is movable and not permanently attached to the engine, so it doesn’t fit the description of a permanently mounted, high-volume water projection tool.
