When using a fire extinguisher, where should you aim?

Aiming at the base of the fire is crucial because this is where the fuel source is located. Fires need fuel, heat, and oxygen to continue burning, so targeting the base effectively disrupts this triangle of combustion. By directing the extinguisher at the base, you can smother the fuel, thereby eliminating the fire's ability to sustain itself.

Aiming at the top, center, or outer edges may not effectively extinguish the flames since these areas may not address the fuel source directly, allowing the fire to persist or even rekindle after an initial application. Therefore, focusing on the base provides the most effective means of extinguishing the fire.
