ch 23 Flashcards
A concentrate used for fighting fires on water-soluble materials and other fuels destructive to regular, AFFF, or FFFP foams, as well as for fires involving hydrocarbons. (NFPA 11)
Alcohol-resistant foam concentrate
A concentrate based on fluorinated surfactants plus foam stabilizers to produce a fluid aqueous film for suppressing hydrocarbon fuel vapors and usually diluted with water to a 1 percent, 3 percent, or 6 percent solution. (NFPA 11)
Aqueous film-forming foam
The manual addition of foam concentrate to a water storage container or tank to make foam solution. (NFPA 1145)
Batch mix
A foam application method that applies the stream onto a nearby object, such as a wall, instead of directly onto the surface of the fire. Also referred to as the bank-shot or bank-down method.
Bounce-off method
Foam for use on fires in Class A fuels. (NFPA 1145)
Class A foam
Foam intended for use on Class B fires. (NFPA 1901)
Class B foam
A type of attack employing both direct attack and indirect attack methods.
Combination attack
A homogenous foam produced by the combination of water, foam concentrate, and air or nitrogen under pressure. (NFPA 11)
Compressed air foam
A foam system that combines air under pressure with foam solution to create foam. (NFPA 1901, 1906)
Compressed air foam system
Actions that are intended to control a fire by limiting its spread to a defined area, avoiding the commitment of personnel and equipment to dangerous areas. (NFPA 1500)
Defensive operation
Firefighting operations involving the application of extinguishing agents directly onto the burning fuel. (NFPA 1145)
Direct attack
A device that uses the Venturi principle to siphon a liquid into a water stream. The pressure at the throat is below atmospheric pressure, allowing liquid at atmospheric pressure to flow into the water stream. (NFPA 1145)
Eductor
A protein-foam solution that uses fluorinated surfactants to produce a fluid aqueous film for suppressing liquid fuel vapors. (NFPA 10)
Film-forming fluoroprotein foam
A protein-based foam concentrate to which fluorochemical surfactants have been added. (NFPA 402)
Fluoroprotein foam
A covering of foam over a surface to insulate, prevent ignition, or extinguish the fire. (NFPA 1145)
Foam blanket
The foaming agent as received from the supplier that, when mixed with water, becomes foam solution. (NFPA 1145)
Foam concentrate
A device installed on a fire pump that meters out foam by pumping or injecting it into the fire stream.
Foam injector
A device or method to add foam concentrate to water to make foam solution. (NFPA 1901)
Foam proportioner
A homogeneous mixture of foam concentrate and water, in the mix ratio required for the application. (NFPA 1145)
Foam solution
A general descriptor for hazardous fire conditions, including flashover,
backdraft, smoke-explosion, flameover, and rapid fire spread. (NFPA 1521)
Hostile fire event
Firefighting operations involving the application of extinguishing agents to reduce the build-up of heat released from a fire without applying the agent directly onto the burning fuel. (NFPA 1145)
Indirect attack
A Venturi-type proportioning device that meters foam concentrate at a fixed or variable concentration into the water stream at a point between the water source and a nozzle or other discharge device. (NFPA 11)
In-line eductor
Actions generally performed in the interior of involved structures that involve a direct attack on a fire to directly control and extinguish the fire. (NFPA 1500)
Offensive operation
Solution produced by introducing a measured amount of foam concentrate into a given amount of water in a storage tank. (NFPA 11)
Premixed foam solution
A type of foam concentrate that is stabilized with metal salts to make a fire-resistant foam blanket. (NFPA 402)
Protein foam
A foam application method that directs the stream into the air above the fire and allows it to gently fall on the surface.
Rain-down method
A foam application method that involves sweeping the stream just in front of the target. Also referred to as the sweep or roll-on method.
Roll-in method
An acronym intended to be used by the first arriving company officer to accomplish important strategic goals on the fire ground.
S.L.I.C.E .- R.S.
An offensive fire attack initiated by an exterior, indirect handline operation into the fire compartment to initiate cooling while transitioning into interior direct fire attack in coordination with ventilation operations.
Transitional attack
