FIREFIGHTER 2 CERTIFICATION EXAM UPDATED SCRIPT
QUESTIONS AND ANSWERS SURE A+
✔✔Hose records - ✔✔A written history of each individual length of fire hose
✔✔Hose line crew - ✔✔The optimal people on a hose line is 4 personnel
✔✔Foam concentrate - ✔✔Firefighting foam is produced by mixing ??? With water and
air to produce a solution that can serve as an effective extinguishing agent.
✔✔Class A foam - ✔✔Used to fight fires involving ordinary combustible materials such
as wood, paper, and textiles. It is also effective on organic materials such as straw and
hay. Increases the effectiveness of water as an extinguishing agent by reducing the
surface tension of water.
✔✔Class B foam - ✔✔Used to fight class B fires, fires involving flammable and
combustible liquids. A blanket of foam is used to smother the fuel of the fire putting it
out.
✔✔Foam solution - ✔✔The product that is actually applied to extinguish a fire or to
cover a spill.
✔✔Compressed air foam systems (CAFS) - ✔✔Relatively new method of making Class
A foam.
✔✔Compressed air foam (CAF) - ✔✔Produced by injecting compressed air into a
stream of water that has been mixed with 0.1 percent to 1 percent foam.
✔✔Protein foam - ✔✔Made from animal by-products. They are effective on Class B
hydrocarbon fires and are applied in 3 percent or 6 percent delivery rates.
✔✔Fluoroprotein foam - ✔✔Made from the same base materials as protein foam but
include additional fluorochemical surfactant additives.
✔✔Film-forming fluoroprotein (FFFP) - ✔✔Composed of protein plus film-forming
fluorinated surface-active agents, which make them capable of forming water solution
films on the surface of most flammable hydrocarbons and of conferring a fuel-shedding
property of the foam generated.
✔✔Aqueous film-forming foam (AFFF) - ✔✔A synthetic based foam that is particularly
suitable for spill related fires involving gasoline and light hydrocarbon fuels.
✔✔Alcohol-resistant foam - ✔✔Formulated so that alcohols and other polar solvents do
not dissolve the foam.
, ✔✔Foam proportioner - ✔✔The device that mixes the foam concentrate into the fire
stream in the proper percentage .
✔✔Foam eductor - ✔✔Draws foam concentrate from a container or storage tank into a
moving stream of water.
✔✔Foam injectors - ✔✔Add the foam concentrate to the water stream under pressure.
✔✔Batch mixing - ✔✔When foam concentrate is poured directly into an apparatus
booster tank to produce foam solution.
✔✔Premixed foam - ✔✔Foam fire extinguishers are filled with premixed foam solution
and pressurized with compressed air or nitrogen.
✔✔Aerating nozzle - ✔✔Nozzle that is designed to introduce more air into the stream
and produce a consistent bubble structure.
✔✔Roll on method (Sweep) - ✔✔Firefighter sweeps the stream along the ground just in
front of the target to produce a quantity of foam and then uses the energy of the stream
to push the foam blanket across the surface.
✔✔Bankshot method - ✔✔The use of an object to deflect the foam stream and let it flow
down onto the burning surface.
✔✔Rain down method - ✔✔Lofting the foam stream into the air above the fire and
letting it fall down gently on the surface.
✔✔Generator - ✔✔Supply of electricity to a scene that needs it.
✔✔Ventalation - ✔✔Must be coordinated with fire suppression efforts to ensure that
both events occur simultaneously and in a manner that supports the attack plan.
✔✔Posts - ✔✔Vertical support members of a vehicle that hold up the roof and form the
upright columns of the passenger compartment.
✔✔A post - ✔✔Located closest to the front of the vehicle. They form sides of the
windshield.
✔✔B post - ✔✔Located between the front and rear doors of a vehicle.
✔✔C post - ✔✔Located behind the rear doors.
