Question 17

Question
Which action of firefighting foam creates a barrier between the fuel and the fire?
Answer
  • Cooling
  • Aerating
  • Separating
  • Penetrating

Question 18

Question
**Foam lowers surface tension of water, allowing it to ___ fires in Class A materials.
Answer
  • cool
  • smother
  • suppress
  • penetrate

Question 19

Question
**Class A foam extinguishes and/or prevents ignition by:
Answer
  • allowing water to penetrate fuels.
  • creating a barrier between the fuel and the fire.
  • preventing air from reaching the fuel or mixing with vapors.
  • lowering the temperature of the fuel and adjacent surfaces.

Question 20

Question
When applied to solid fuels, Class A foam blankets the fuel, controls flames, then:
Answer
  • changes the pH of the water.
  • expands at a ratio of 20-to-1.
  • dissipates into the air, leaving no residue.
  • breaks down, releasing water to cool the fuel.

Question 21

Question
Class B foams are especially effective on:
Answer
  • wild land and brush fires.
  • unignited hazardous liquids.
  • fires of ordinary combustibles.
  • hydrocarbon fuels and polar solvents.

Question 22

Question
The degree of foam expansion depends on the type of foam concentrate, accurate proportioning, quality of the foam concentrate and:
Answer
  • method of aeration.
  • outside air temperature.
  • length of discharge hose.
  • wind direction and velocity.

Question 23

Question
**Which of the following statements about Class A foam concentrates is MOST accurate?
Answer
  • Class A foam is used for structural fires, but is not suitable for wildland fires.
  • Class A foam is used to prevent ignition of fires involving flammable and combustible liquids.
