How long should you aim the fire extinguisher at the base of the flames?

Aiming the fire extinguisher at the base of the flames until the fire is fully extinguished is critical for effectively combating the fire. The base of the flames is where the fuel source is located, and directing the extinguishing agent there maximizes its effectiveness in suppressing the fire.

By continuously targeting this area, you're more likely to eliminate the source of the flames, reducing the chance of re-ignition. It's important to ensure the fire is thoroughly out before you stop using the extinguisher, as any remaining heat or fuel can reignite the flames.

Focusing solely on a few seconds, a specific duration such as 30 seconds, or stopping when you run out of the extinguishing agent does not guarantee that the fire is fully under control or extinguished. The key is to keep applying the agent until there is no visible flame and any remaining smoke or heat indicates that the fire is truly out. This method emphasizes safety and efficacy in fire suppression efforts.
