Accessibility Ability of fire apparatus to get close enough to a building to conduct emergency operations.

Accident Unplanned, uncontrolled event that results from unsafe acts of people and/or unsafe occupational conditions, either of which can result in injury.

Adapter Fitting for connecting hose couplings with dissimilar threads but with the same inside diameter.

Adjustable Flow Nozzle Nozzle designed so that the amount of water flowing through the nozzle can be increased or decreased at the nozzle.

Aerial Apparatus Fire fighting vehicle equipped with a hydraulically operated ladder or elevating platform for the purpose of placing personnel and/or water streams in elevated positions.

Aerial Device General term used to describe the hydraulically operated ladder or elevating platform attached to a specially designed fire apparatus.

Aerial Ladder Power-operated (usually hydraulically) ladder mounted on a special truck chassis.

Aerial Ladder Platform Power-operated (usually hydraulically) ladder with a passenger-carrying device attached to the end of the ladder.

Agent Generic term used for materials that are used to extinguish fires.

Air-Aspirating Foam Nozzle Foam nozzle especially design d to provide the aeration required to make the highest quality foam possible; most effective appliance for the generation of low-expansion foam.

Air Cascade System Three or more large air cylinders, each usually with a capacity of 300 cubic feet, from which SCBA cylinders are recharged.

Air Chamber Chamber filled with air that eliminates pulsations caused by the operation of piston or rotary gear pumps.

Air-Supply Unit Apparatus designed to refill exhausted SCBA air cylinders at the scene of an ongoing emergency.

Ammeter Gauge that indicates both the amount of electrical current being drawn from and provided to the vehicle's battery.

Angle of Approach Angle formed by level ground and a line from the point where the front tires of a vehicle touch the ground to the lowest projection at the front of the apparatus.

Angle of Departure Angle formed by level ground and a line from the point where the rear tires of a vehicle touch the ground to the lowest projection at the rear of the apparatus.

Anti-Electrocution Platform Slide-out platform mounted beneath the side running board or rear step of an apparatus equipped with an aerial device. This platform is designed to minimize the chance of the driver/ operator being electrocuted should the aerial device come in contact with energized electrical wires or equipment.

Apparatus Bay (Apparatus Room) Area of the fire station where apparatus are parked.

Apparatus Engine Diesel or gasoline engine that powers the apparatus drive chain and associated fire equipment. Synonymous with Power Plant.

Appliance Generic term applied to any nozzle, wye, siamese, deluge monitor, or other piece of hardware used in conjunction with fire hose for the purpose of delivering water.

Applicator Pipe Curved pipe attached to a nozzle for precisely applying water over a burning object.

Aqueous Film Forming Foam (AFFF) Synthetic foam concentrate that, when combined with water, is a highly effective extinguishing and blanketing agent on hydrocarbon fuels.

Articulating Aerial Platform Aerial device that consists of two or more booms that are attached with hinges and operate in a folding manner. A passenger-carrying platform is attached to the working end of the device.

Articulating Boom Arm portion of the articulating aerial platform.

Atmospheric Pressure Pressure exerted by the atmosphere at the surface of the earth due to the weight of air. Atmospheric pressure at sea level is about 14.7 psi. Atmospheric pressure increases as elevation is decreased below sea level and decreases as elevation increases above sea level.

Attack Hose Hose between the attack pumper and the nozzle(s); also, any hose used in a handline to control and extinguish fire. Minimum size is 1 1/2 inch.

Attack Lines Hoselines or fire streams used to attack, contain, or prevent the spread of a fire.

Attack Pumper Pumper that is positioned at the fire scene and is directly supplying attack lines.

Automatic Nozzle Fog stream nozzle that automatically corrects itself to provide a good stream at the proper nozzle pressure.

Average Daily Consumption Average of the total amount of water used each day during a one-year period.

Back Flushing The cleaning of afire pump or piping by flowing water through it in the opposite direction of normal flow.

Baffle Intermediate partial bulkhead that reduces the surge effect in a partially loaded liquid tank.

Balanced Pressure Proportioner A foam concentrate proportioner that operates in tandem with a fire water pump to ensure a proper foam concentrate-to-water mixture.

Ball Valve Valve having a ball-shaped internal component with a hole through its center that permits water to flow through when aligned with the waterway.

Bed Ladder Pipe Nontelescoping section of pipe, usually 3 or 3 1/2 inches in diameter, attached to the underside of the bed section of the aerial ladder for the purpose of deploying an elevated master stream.

Bleeder Valve Valve on a gate intake that allows air from an incoming supply line to be bled off before allowing the water into the pump.

Booster Apparatus Fire department apparatus designed specifically for fighting wildland fires. Synonymous with Brush Apparatus, Brush Patrol, Brush Pumper, Wildland Fire Apparatus, and Field Unit.

Booster Hose Fabric reinforced, rubber-covered, rubber-lined hose. Booster hose is generally carried on apparatus on a reel and is used for the initial attack and extinguishment of incipient and smoldering fires. Also called Hard Line and Red Line.

Booster Pump Fire pump used to boost the pressure of the existing water supply within a fixed fire protection system.

Booster Reel Mounted reel on which booster hose is carried.

Booster Tank Water storage receptacle carried directly on the apparatus. NFPA 1901 specifies that Class A pumpers must carry at least 500 gallons. Synonymous with Water Tank.

Bourdon Gauge Most common device used to measure water system pressures.

Bourdon Tube Part of a pressure gauge that has a curved, flat tube that changes its curvature as pressure changes. This movement is then transferred mechanically to a pointer on the dial.

Brake Limiting Valve Valve that allows the vehicle's brakes to be adjusted for the current road conditions.

Braking Distance Distance the vehicle travels from the time the brakes are applied until it comes to a complete stop.

Breakover Angle Angle formed by level ground and a line from the point where the rear tires of a vehicle touch the ground to the bottom of the frame at the wheelbase midpoint.

British Thermal Unit (Btu) Amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. One Btu = 1.055 kj.

Broken Stream Stream of water that has been broken into coarsely divided drops.

Brush Apparatus Fire department apparatus designed specifically for fighting wildland fires. Synonymous with Booster Apparatus, Brush Patrol, Brush Pumper, Wildland Fire Apparatus, and Field Unit.

Brush Patrol Fire department apparatus designed specifically for fighting wildland fires. Synonymous with Booster Apparatus, Brush Apparatus, Brush Pumper, Wildland Fire Apparatus, and Field Unit.

Brush Pumper Fire department apparatus designed specifically for fighting wildland fires. Synonymous with Booster Apparatus, Brush Patrol, Brush Apparatus, Wildland Fire Apparatus, and Field Unit.

Bumper Structure designed to provide front or rear end protection of a vehicle.

Bumper Line Preconnected hoseline located on the apparatus bumper.

Butterfly Valve Type of control valve that uses a flat baffle operated by a quarter-turn handle.

Calibrate To standardize or adjust the increments on a measuring instrument.

Canteen Unit Emergency vehicle that provides food, drinks, and other rehabilitative services to emergency workers at extended incidents.

Capacity Maximum ability of a pump or water distribution system to deliver water.

Cascade Air Cylinders Large air cylinders that are used to refill smaller SCBA cylinders.

Cascade System Three or more large air cylinders, each usually with a capacity of 300 cubic feet, that are interconnected and from which smaller SCBA cylinders are recharged.

Catch Basin Collapsible storage tank used during a relay or shuttle operation to hold water from water tanks or hydrants. This water can then be used to supply attack apparatus. Synonymous with Portable Tank, Fold-a-Tank, Portable Basin, or Porta-Tank.

Cellar Pipe Special nozzle for attacking fires in basements, cellars, and other spaces below the attack level.
