🔍 Key Concepts

• Class B fires involve flammable liquids like fuel oil, gasoline, and solvents • The main methods of extinguishing fire: cooling, smothering (removing oxygen), removing heat, or breaking the chemical chain reaction • Which methods are most effective on burning liquids versus solid materials

💭 Think About

• Ask yourself: For a pool of burning fuel oil, which method is practical and safe—cooling the liquid, cutting off its oxygen, or some other approach? • Think about which method works best when water would be dangerous or could spread the burning liquid. • Consider how a foam extinguisher works on a fuel spill—what is it actually doing to the fire?

✅ Before You Answer

• Verify what Class B specifically refers to (type of fuel, liquid vs solid). • Check which fire-fighting principle is associated with foam and CO₂ extinguishers commonly used on fuel fires. • Confirm which option best describes removing oxygen from the fire without relying on cooling solid materials.
