🔍 Key Concepts

• reflash and why fuel must be cooled below its ignition temperature • difference between smothering (removing oxygen) and cooling (removing heat) in fire extinguishment • properties of common agents: CO2, water, foam, water fog

💭 Think About

• Think about which agent mainly works by displacing oxygen or smothering the flame, rather than by cooling the burning material itself. • Ask yourself: after the flame goes out, which agent leaves the fuel still hot enough that, if air is reintroduced, it can ignite again? • Compare which of these agents actually absorbs a lot of heat from the fuel (good cooling) versus which agent leaves very little cooling effect.

✅ Before You Answer

• Verify which agent is known as a clean agent that leaves no cooling water or residue on the fuel. • Check which agents (water stream, foam, water fog) primarily cool by heat absorption and evaporation. • Confirm which agent stops the flame by oxygen displacement but provides minimal cooling of the fuel.
