When using a fire extinguisher, which method is recommended?

Aiming at the base of the fire when using a fire extinguisher is crucial because this is where the combustible material is located. Effectively targeting the base ensures that the extinguishing agent can directly impact the source of the fire, creating a more efficient means of suppression. The base of the fire is where the heat and fuel combine, so by targeting this area, you disrupt the fire’s ability to sustain itself.

Using a wide arc or a continuous stream may not provide the same level of effectiveness, as these methods could miss the critical point of contact with the fuel. Instead of directly addressing the heat source, they could waste the extinguishing agent or spread the fire. Waiting until the fire is large before taking action significantly increases the risk involved, making it more challenging to control and extinguish the flames effectively. Therefore, focusing on the base maximizes the potential for a successful extinguishment and ensures safety for the person operating the extinguisher and others in the vicinity.
