🔍 Key Concepts

• Class B fires (flammable liquids and gases) and how foam works to extinguish them • Purpose of a foam blanket: smothering, cooling, and preventing re‑ignition • Effect of disturbing vs. preserving the foam layer after knockdown

💭 Think About

• Think about what foam is actually doing on top of a fuel surface right after the flames go out. What happens if air or vapor can reach the fuel again? • Which option best maintains the foam’s ability to prevent re‑ignition, and which options would weaken or destroy that protection? • Ask yourself: immediately after extinguishment, is your priority rapid cleanup or maintaining control of the fuel and vapors?

✅ Before You Answer

• Verify which actions would break, thin, or wash away the foam blanket and expose the fuel surface again. • Consider which choice focuses on preserving the seal between the fuel and the air right after the fire is out. • Eliminate any options that involve walking through, sweeping away, or otherwise disrupting the foam blanket.
