🔍 Key Concepts

• How CO₂ extinguishers work (do they cool, smother, or remove fuel?) • Where a fire actually sustains itself (flame tips versus base of the fire) • Proper sweeping technique with portable extinguishers

💭 Think About

• Think about which part of the fire triangle CO₂ mainly affects and where you need to apply it to be most effective. • Consider whether CO₂ is heavier or lighter than air and how that affects where you should aim the discharge. • Compare a quick blast in one spot versus a controlled, side-to-side motion—what gives better coverage of the burning material?

✅ Before You Answer

• Verify which option focuses on the fuel surface rather than just the visible flames. • Check which method keeps the CO₂ on the fire long enough to smother it instead of letting it quickly disperse. • Eliminate any choice that relies on the agent bouncing off surfaces rather than being applied directly to the burning area.
