🔍 Key Concepts

• How foam behaves when it is applied on top of a flammable liquid fire • Difference between cooling, smothering, and chemical reaction in fire extinguishment • Fire triangle: fuel, heat, oxygen

💭 Think About

• When foam is spread over burning fuel, what happens to the contact between the fuel and the surrounding air? • Does foam usually rely more on changing the chemistry of the fuel, or on blocking something needed to keep the fire going? • Think about what a thick blanket does when placed over a small fire—what part of the fire triangle is most affected?

✅ Before You Answer

• Identify which choice best describes blocking oxygen from reaching the fire • Eliminate any answer that suggests the foam must chemically react with the fuel to work • Focus on the answer that describes forming a barrier or blanket over the burning surface
