Deluge gun

Installation

Deluge guns are often fitted to fire boats, tug boats, and atop large fire trucks for use in manual firefighting, where they can be aimed and operated by one firefighter and are used to deliver water or foam from outside the immediate area of the fire. Deluge guns are sometimes installed in fixed fire protection systems to protect high hazards, such as aviation hangars and helicopter landing pads. Similarly, facilities with highly flammable material such as oil refineries may have permanently-installed deluge guns. Most apparatus-mounted deluge guns can be directed by a single firefighter, compared to a standard fire hose which normally requires several. Deluge guns can be automatically positioned for fixed systems, or may have portable designs. The latter option enables a firefighter to set up the gun to apply water to a blaze, before leaving it in place to attend to other tasks.
