Where should you aim the nozzle or hose of a fire extinguisher?

Aiming the nozzle or hose of a fire extinguisher at the base of the fire is the most effective technique for extinguishing flames. This method allows the extinguishing agent to directly tackle the fuel source that is burning. By targeting the base, the extinguisher can effectively interrupt the chemical reactions taking place that sustain the fire, making it possible to eliminate the fire rather than merely suppressing its flames.

When using a fire extinguisher, focusing on the base ensures that the agent directly impacts the source of the fire, leading to a quicker and more efficient extinguishing process. This approach minimizes the chance of the flames spreading and reduces the amount of extinguishing agent that might be wasted by simply spraying it over the flames or at higher areas where it may not be as effective.
