Which of the following is an accurate statement about using a fire extinguisher?

Using a fire extinguisher effectively is crucial for ensuring safety and controlling fires efficiently. The correct approach involves aiming at the base of the flames, as this is where the fuel source is located. Directing the extinguisher at the base helps to eliminate the fire effectively by suffocating it or cooling it down, rather than just dispersing the flames further.

Aiming at the tip of the flames, as suggested in one of the options, would not effectively extinguish the fire since the flames could simply disperse without addressing the source. Additionally, spraying continuously at the fire is not the most effective method; rather, intermittent sweeping motions are recommended to cover the flames evenly. Finally, while it's wise to use a fire extinguisher for small fires, this statement doesn’t encompass the broader principle of using extinguishers, which may also be necessary in larger situations if safely possible. Thus, the guidance to use a sweeping motion and aim at the base of the flames is the most accurate and effective statement regarding fire extinguisher use.
