Adjustable-gallonage fog nozzle
A nozzle that allows the operator to select a desired flow from several settings.
The process of inducing air into the foam solution, which expands and finishes the foam.
Alcohol-resistant foam
Used for fighting fires involving water-soluble materials or fuels that are destructive to other types of foams. Some alcohol-resistant foams are capable of forming a vapor-suppressing aqueous film on the surface of hydrocarbon fuels. (NFPA 412)
Aqueous film-forming foam (AFFF)
A concentrated aqueous solution of one or more hydrocarbon and/or fluorochemical surfactants that forms a foam capable of producing a vapor-suppressing, aqueous film on the surface of hydrocarbon fuels. (NFPA 403)
Attack engine
An engine from which attack lines have been pulled.
Automatic-adjusting fog nozzle
A nozzle that can deliver a wide range of water stream flows. It operates by means of an internal spring-loaded piston.
Bankshot (bank-down) method
A method that applies the stream onto a nearby object, such as a wall, instead o directly aiming at the fire.
Batch mixing
Pouring foam concentrate directly into the fire apparatus water tank, thereby mixing a large amount of foam at one time.
Booster hose (booster line)
A noncollapsible hose used under positive pressure having an elastomeric or thermoplastic tube, a braided or spiraled reinforcement, and an outer protective cover. (NFPA 1962)
Breakaway nozzle
A nozzle with a tip that can be separated from the shut-off valve.
Bresnan distributor nozzle
A nozzle that can be placed in confined spaces. The nozzle spins, spreading water over a large area.
Butterfly valves
Valves that are found on the large pump intake valve where the hard or soft suction hose connects.
Cellar nozzle
A nozzle used to fight fires in cellars and other inaccessible places. The device works by spreading water in a wide pattern as the nozzle is lowered through a hole into the cellar.
Class A foam
Foam intended for use on Class A fires. (NFPA 1150)
Class B foam
Foam intended for use on Class B fires. (NFPA 1901)
Compressed air foam (CAF)
Class A foam produced by injecting compressed air into a stream of water that has been mixed with 0.1 percent to 1.0 percent foam.
Compressed air foam system
A foam system that combines air under pressure with foam solution to create foam. (NFPA 1901)
Film-forming fluoroprotein (FFFP)
A protein-based foam concentrate incorporating fluorinated surfactants that forms a foam capable of producing a vapor-suppressing aqueous film on the surface of hydrocarbon fuels. This foam can show an acceptable level of compatibility with dry chemicals and might be suitable for use with those agents. (NFPA 412)
Fixed-gallonage fog nozzle
A nozzle that delivers a set number of gallons per minute (liters per second) as per the nozzle’s design, no matter what pressure is applied to the nozzle.
Fluoroprotein foam
A protein-based foam concentrate to which fluorochemical surfactants have been added. This has the effect of giving the foam a measurable degree of compatibility with dry chemical extinguishing agents and an increase in tolerance to contamination by fuel. (NFPA 402)
Foam concentrate
A concentrated liquid foaming agent as received from the manufacturer. (NFPA 11)
Foam eductor
A device placed in the hose line that draws foam concentrate from a container and introduces it into the fire stream.
Foam injector
A device installed on a fire pump that meters out foam by pumping or injecting it into the fire stream.
Foam proportioner
A device or method to add foam concentrate to water to make foam solution. (NFPA 1901)
Foam solution
A homogeneous mixture of water and foam concentrate in the proper proportions. (NFPA 1901)
Fog-stream nozzle
A nozzle that is placed at the end of a fire hose and separates water into fine droplets to aid in heat absorption.
Handline nozzle
A nozzle with a rated discharge of less than 1325 L/min (350 gpm). (NFPA 1964)
Low-volume nozzle
A nozzle that flows 40 gallons per minute (2.5 liters per second) or less.
Master stream device
A large-capacity nozzle that can be supplied by two or more 2½-inch (64-mm) hose lines or large-diameter hose or fixed piping. It can flow between 350 and 1500 gallons per minute (22.1 and 94.6 liters per second). These devices include deck guns and portable ground monitors.
Master stream nozzle
A nozzle with a rated discharge of 1325 L/min (350 gpm) or greater. (NFPA 1964)
Medium-diameter hose (MDH)
Hose with a diameter of 2½ or 3 inches (64 or 76 millimeters).
A constricting appliance attached to the end of a fire hose or monitor to increase the water velocity and form a stream. (NFPA 1965)
Nozzle shut-off
A device that enables the fire fighter at the nozzle to start or stop the flow of water.
Piercing nozzle
A nozzle that can be driven through sheet metal or other material to deliver a water stream to that area.
Premixed foam
Solution produced by introducing a measured amount of foam concentrate into a given amount of water in a storage tank. (NFPA 11)
Protein foam
A protein-based foam concentrate that is stabilized with metal salts to make a fire-resistant foam blanket. (NFPA 402)
Small-diameter hose (SDH)
Hose with a diameter ranging from 1 to 2 inches (25 to 51 millimeters).
Smooth-bore nozzle
A nozzle that produces a straight stream that is a solid column of water.
Smooth-bore tip
A nozzle device that is a smooth tube, which is used to deliver a solid column of water.
Sweep (roll-on) method
A method of applying foam that involves sweeping the stream just in front of the target.
Triple-layer load
A hose loading method in which the hose is folded back onto itself to reduce the overall length to one-third before loading the hose in the bed. This load method reduces deployment distances.
Water curtain nozzle
A nozzle used to deliver a flat screen of water that forms a protective sheet of water to protect exposures from fire.
