🔍 Key Concepts

• Class B fire characteristics (flammable liquids and gases) • How dry chemical extinguishers work (smothering and interrupting the chemical reaction) • Correct aiming point and sweeping technique when using portables

💭 Think About

• Where does a flammable liquid fire actually get its fuel and burn the most intensely: on the surface, in the flames, or at a specific point? • If you aim too high into the flames, what happens to most of the dry chemical? Does it reach the burning fuel? • When starting your attack on a pool of burning liquid, is it safer and more effective to begin at the center or work from an outer area inward?

✅ Before You Answer

• Identify where the fuel surface is in a Class B fire and where the fire is being sustained • Recall that dry chemical stream should stop the chemical reaction at the fuel surface, not just cool the flames • Remember standard firefighting advice: start your application at a safer, more controllable edge and then sweep across the fire area
