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 is crucial for effectively extinguishing flames. The base is where the fuel source is located, and targeting this area disrupts the combustion process. Using a sweeping motion helps to cover the entire area of the fire, ensuring that all flames are addressed and that the fire is thoroughly extinguished rather than just scattering the flames or burning embers. This method can prevent the fire from reigniting by cooling the fuel and eliminating the heat needed for combustion.

In fire safety, it is important to remember that attacking the flames directly from the top or the sides may not effectively eliminate the fire, as the root cause at the base remains untouched. Additionally, focusing on the flames without movement may not adequately address the source of the fire and could lead to an ineffective attempt at extinguishing it. Thus, targeting the base of the fire is the most effective strategy for a successful fire extinguishment.
