🔍 Key Concepts

• foam firefighting principles for flammable liquid fires • purpose of foam: to separate fuel from oxygen and prevent vapor release • difference between smothering a fire vs. cooling or penetrating it

💭 Think About

• Ask yourself: What is the MAIN job of foam when used on burning liquid fuel—does it need to soak in, mix with the fuel, or form a barrier? • Consider how foam behaves on top of a liquid: does it work better floating on the surface or sinking into the fuel? • Which choice best describes the condition where vapors from the fuel are blocked from reaching the air?

✅ Before You Answer

• Verify which option describes a continuous blanket over the fuel surface. • Eliminate any choice that requires foam to mix with or sink into the burning fuel. • Focus on the answer that best prevents oxygen from reaching fuel vapors and vapors from escaping.
