Where should you aim a fire extinguishers steam when extinguishing a fire?

When using a fire extinguisher, aim the steam or agent at the base of the fire. This is crucial because the base is where the fuel is located, and effectively targeting it helps to cut off the fire's source of combustion. Additionally, using a sweeping motion from side to side can help ensure that the fire is fully extinguished. Always maintain a safe distance while operating the extinguisher.
