Where should you aim a fire extinguisher's stream when extinguishing a fire?

Aiming a fire extinguisher's stream at the base of the fire and using a sweeping motion is the most effective approach for extinguishing flames. This method targets the fuel that is igniting and allows the extinguishing agent to smother the fire at its source, which is crucial for stopping its spread. By focusing on the base, you are directly addressing the heart of the fire rather than dissipating your efforts on the flames or smoke above.

Using a sweeping motion ensures that the extinguishing agent covers a broader area and benefits from spreading evenly across the fuel, maximizing the chance of successfully putting out the fire. This technique allows for effective use of the extinguisher and helps to reduce the risk of reigniting.

In contrast, aiming at the top of the flames may not effectively smother the fire since the extinguishing agent may not reach the fuel source. Directing the stream into the smoke does not address the fire itself and can be dangerous, as it may cause the flames to flare up. Aiming away from the fire entirely is counterproductive, as it provides no benefit in extinguishing the flames.
