Where should you direct the fire extinguisher chemical stream?

Directing the fire extinguisher chemical stream at the base of the flame is the most effective method for extinguishing a fire. This approach focuses on the actual source of the fire where the combustible material is located. By targeting the base, you can cut off the oxygen supply and remove the heat from the fire, thus addressing the fire's fuel and reducing its intensity.

When using a fire extinguisher, aiming at the flame's center, head, or edge may not have the same effect. For example, targeting the center or head of the flame does not address the fuel source directly and may only temporarily suppress the fire without eliminating it. Similarly, directing the stream at the edge may not penetrate deeply enough to extinguish the flame effectively. Therefore, concentrating on the base ensures that you are tackling the fire where it truly begins, maximizing the chances of successful extinguishment.
