Which action is not part of the recommended fire extinguisher technique?

• A. Use the extinguisher from a safe distance.
• B. Aim at the base of the fire.
• C. Sweep until extinguished.
• D. Sweep toward the top of the fire.

Answer: (D)

The method tested is how to use a fire extinguisher effectively to knock down a small blaze. The action that is not part of the proper technique is sweeping toward the top of the fire. When you use an extinguisher, you want the discharge to reach the fuel at the base of the flames. Aiming at the base allows the suppressant to interrupt the fire at its source and, with a sweeping motion, flood the area across the base to extinguish it. Sweeping toward the top doesn’t target the fuel source and can let the fire continue or spread, especially since heat and flames concentrate at the base where the fuel is most available. Keeping a safe distance protects you from heat and fumes, aiming at the base targets the right part of the fire, and sweeping across the base until you’re sure it’s out completes the proper technique.
