🔍 Key Concepts

• Fire classes (A, B, C, D, K) and what type of fuel each covers • Behavior of flammable and combustible liquids when water is applied • How foam, CO₂, dry chemical, and water act to extinguish a fire (cooling, smothering, interrupting chemical chain reaction)

💭 Think About

• First decide what class of fire burning liquid paint belongs to, based on its fuel type • For that class of fire, consider which agents are normally recommended and which agents may make the situation worse • Think about how each agent affects a spreading liquid surface fire: does it spread the liquid, float on it, or smother it?

✅ Before You Answer

• Verify which agent can spread flammable liquids instead of extinguishing them • Check which agents are specifically rated for Class B (flammable liquid) fires • Be sure you know which agents work mainly by smothering the surface versus just cooling with water
