AQUEOUS FILM-FORMING FOAM (AFFF)  look up translate image
(pronounced "A-Triple-F", also called "Class B") Bubbles that act as surfactant to coat and penetrate ordinary fuels (e.g., wood, paper) to prevent them from burning at normal temperatures; also used on "Class B" (oil/gasoline) fires to spread a non-volatile film over the surface of the fuel. Applied using eductor or Compressed air foam system (CAFS) and pumped through fire hose to a foam nozzle (or sometimes a less-effective fog nozzle).
ATTACK HOSE  look up translate image
(Attack Line) A use classification of a fire fighting hose connected to output of a pump or other pressure source (e.g., gravity). Firehose used to apply water or other fire fighting agent directly to a fire or burning substance. Typically of 21⁄2 inches (64 mm) diameter or less in the United States. Historically 1.5 inch hose was the primary initial attack line but has been supplanted in most of the US by 1.75-inch-diameter (44 mm) hose that carries 175 gallons per minute. Two-inch hose is available as an option.
ATTIC LADDER  look up translate image
narrow, collapsible ladder used to access an attic space via a scuttle hole, which are often found in closets and other narrow passages. Also known as a closet ladder, folding ladder or "pencil ladder." Required to be carried on pumpers by NFPA 1901.
AUTOMATIC SPRINKLER  look up translate image
system of pipes serving fire sprinklers, for automatically directing water to a fire when the sprinkler is heated to its actuation tempereature (usually 155 deg F). The piping may be normally pressurized with water ("wet") or with air ("dry"), depending upon the application. When a sprinkler-head (or heat sensor) detects heat from a fire, the sprinkler opens, automatically spraying water onto the fire area.
BA  look up translate image

BIG GUNS  look up translate image
Reference the term applied to high volume water/foam delivery devices typically associated with Footprint(TM) process methodologies for storage tank firefighting.
BOMB LINE  look up translate image
A preconnected attack line, typically 2½ inch in diameter, used in the same manner and purpose as a Trash Line. Bomb Lines are stored either on the front bumper of the apparatus or in an exterior (exposed) side well. Bomb Lines are typically shorter length than Cross Lays, and are intended for use against dumpster fires, etc., where a longer length of hose (and consequent rebedding after the suppression is complete) is not desired.
BOOSTER HOSE  look up translate image
Small-diameter fire hose (3/4–1 inch), often carried on booster reel, preconnected to pump of an engine (and the booster tank) for putting out small fires near the truck without having to connect to a fire hydrant; easily recovered with a motorized reel. Also known as "red line" for the common red rubberized outer layer. Booster hose is also used for High Pressure Fog (HPF) applications.
BRANCH PIPE  look up translate image
See Nozzle
BRESNAN CELLAR NOZZLE  look up translate image
Rotating nozzle tip having two or more outlets forming water jets that propel the tip while spraying water in a circular pattern; conveniently attached to several feet (a meter) of rigid pipe with handles or legs for supporting the nozzle while it is suspended through a hole in the floor above.
BULK TANK  look up translate image
Large tank designed to be transported to an incident and left; larger than a tote tank.
BUNKERS (OR "BUNKER GEAR")  look up translate image
colloquial term for protective pants and boots kept near a firefighter’s bunk (cot) for rapid deployment; more modernly includes firefighting jacket. Basis for command to "Bunker up!" in preparation for hazardous duties. May also refer to entire protective clothing ensemble. Also known as "turnouts" or "turnout gear."
CELLAR PIPE  look up translate image
Cellar Nozzle. The Bresnan Nozzle is a distributing type nozzle that is inserted through an opening in the floor and into the space below, typically a basement or cellar. The nozzle directs a broken stream horizontally, either extinguishing or controlling the fire enough to allow a direct attack to be safely made. The Baker Cellar Pipe consists of an smoothbore, straight stream nozzle on the end of a brass pipe 36-inches long or more that can be remotely angled from the floor above by firefighters to direct the stream to the desired cellar location.
CFA 3-THREAD  look up translate image

COMBINATION NOZZLE  look up translate image
A low pressure Fog Nozzle (usually 120 to 150 lbf/in² or 820 to 1030 kPa that can be adjusted to produce a near straight stream. Also commonly referred to as a Taskforce Tip (TFT).
COMPRESSED AIR FOAM SYSTEM (CAFS)  look up translate image
A water / surfactant (foam) mixture, with compressed air forced into the mix. The result is a very homogeneous, small "air bubble" distribution; the resulting suppression agent is the consistency of soggy shaving cream, consisting of relatively pure surface area and little actual water. CAF is gaining favor in selected compartmental fire scenarios because of its high (explosive) conversion rate, on top of the penetrative advantages of the surfactant. It is also inappropriate for many fire scenarios...(more)

A master stream device mounted to top deck of pumper.
DELIVERY  look up translate image
Term for any hose that conveys water to a fire e.g., each outlet from a fire appliance supplies a delivery with water.
DELUGE GUN  look up translate image
A master stream device that can be positioned on the ground based on the need of the incident commander.
DELUGE SYSTEM  look up translate image
Type of sprinkler system where sprinkler heads do not have individual valves, and the water (or other extinguishing agent) is disbursed from all sprinkler heads simultaneously when a central (or zoned) valve is triggered by a sensor (or manually). This is typically reserved for industrial areas where rapid fire spread must be prevented at the cost of damaging non-burning materials.
DENVER DOOR OPENER  look up translate image
