What are the two fixed master streams?

• A. Deck gun and ARFF turret
• B. Deck gun
• C. ARFF turret
• D. Aerial waterway

Answer: (A)

Fixed master streams are large-volume water streams that come from outlets mounted directly on a fire apparatus, not from hand-held lines. They are designed for rapid knockdown from a fixed position, controlled from the vehicle rather than by a firefighter holding the nozzle. The deck gun and the ARFF turret are the two most common fixed master streams because each is permanently mounted on the apparatus and capable of delivering a high-flow stream from a single, controllable point. The deck gun sits on top or at the front of the unit and can be aimed and operated from the cab controls, providing a high-volume stream from a fixed location. The ARFF turret, found on airport crash/rescue vehicles, is also a fixed mounting that can rotate to sweep water but remains a stationary outlet on the vehicle, capable of delivering substantial flow for aircraft incidents. While an aerial waterway exists as another fixed delivery option on some platforms, in this context the two primary fixed master streams are the deck gun and the ARFF turret.
