What should be done after pulling the pin on a fire extinguisher according to the PASS method?

The correct action after pulling the pin on a fire extinguisher according to the PASS method is to aim the nozzle at the base of the fire. This is crucial because the base is where the fuel source is located, and directing the extinguishing agent there is the most effective way to smother the flames and eliminate the fire. By targeting the base, you can interrupt the chemical reaction that sustains the fire, leading to more effective suppression.

In applying the PASS method—Pull, Aim, Squeeze, Sweep—this step is essential for maximizing the extinguisher's effectiveness and ensuring safety during the firefighting effort. Assigning focus to the base also helps avoid unnecessary exposure to the flames and ensures that the extinguishing agent accurately impacts the source of the fire.
