Where should you aim an extinguisher agent when fighting a fire?

When fighting a fire with an extinguisher, aiming at the base of the fire is crucial because this is where the fuel is located. Targeting the base helps to extinguish the flames more effectively by cutting off the fire’s supply of fuel, which is essential for combustion. By directing the agent at this point, it can better penetrate any flames and cool the fuel source, leading to successful suppression of the fire.

Aiming at the middle might not be effective, as this ignores the source of combustion. Targeting the top of the fire can also be less effective since the flames may not be the main sustaining factor; extinguishing the flames alone doesn’t address the fuel. Similarly, aiming at the area around the fire does not address the ignition source directly and may leave the fire unresolved, potentially allowing it to reignite.
