Command Considerations
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.
What is a defensive operation?
A covering of foam over a surface to insulate, prevent ignition, or extinguish the fire.
What is a foam blanket?
Class B foam concentrates are designed to be used in either 3% or __% solutions.
What is 6?
FFFP
What is film-forming fluoroprotein foam?
A device installed on a fire pump that meters out foam by pumping or injecting it into the fire stream.
What is a foam injector?
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.
What is the bounce-off method?
A general descriptor for hazardous fire conditions, including flashover, backdraft, smoke-explosion, flameover, and rapid fire spread.
What is a hostile fire event?
The foaming agent as received from the supplier that, when mixed with water, becomes foam solution.
What is foam concentrate?
This percentage of Class B foam should be used on polar solvents.
What is 6%?
This type of foam is formulated so that alcohols and other polar solvents do not dissolve the foam.
What is alcohol-resistant foam concentrate?
A homogenous foam produced by the combination of water, foam concentrate, and air or nitrogen under pressure.
What is compressed air foam?
A foam application method that directs the stream into the air above the fire and allows it to gently fall on the surface.
What is the rain-down method?
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.
What is an indirect attack?
The type of foam used to fight fires involving ordinary combustible materials, such as wood, paper, and textiles.
What is Class A foam?
Class A foams are usually formulated to be mixed with water in ratios from 0.1% to __%.
A protein-based foam concentrate to which fluorochemical surfactants have been added.
What is fluoroprotein foam?
This draws foam concentrate from a container or storage tank into a moving stream of water or hose line.
What is a foam eductor?
During hose testing, pressure in the line must be maintained for __ minutes to complete the test.
What is 5?
This acronym was developed to help first-arriving company officers remember the steps to be taken for initial engine company operations.
What is S.L.I.C.E.-R.S.?
A homogenous mixture of foam concentrate and water, in the mix ratio required for the application.
What is foam solution?
A protein-based foam concentrate that is stabilized with metal salts to make a fire-resistant foam blanket.
What is protein foam?
This is a synthetic-based foam that is particularly suitable for spill-related fires involving gasoline and light hydrocarbon fuels.
What is AFFF(Aqueous film-forming foam)
A device method to add foam concentrate to water to make foam solution.
What is a foam proportioner?
A foam application method that involves sweeping the stream just in front of the target.
What is roll-in method?
A type of attack employing both direct attack and indirect attack methods.
What is a combination attack?
The type of foam used on flammable and combustible liquids.
What is Class B foam?
3% Class B foams are designed to be used for ordinary __________.
What are hydrocarbons?
CAFS
What is compressed air foam system?
The manual addition of foam concentrate to a water storage container or tank to make foam solution.
What is batch mix?
True or False
For hose testing, the hose should be marked around the coupling to determine slippage during the test.
What is true?
