What should one do immediately after pulling the pin on a fire extinguisher?

Immediately after pulling the pin on a fire extinguisher, it is crucial to aim the nozzle at the base of the fire. This step is essential because doing so allows the fire extinguisher to effectively target the source of the flames. Aiming at the base rather than at the flames themselves helps in extinguishing the fire more efficiently, as it directly addresses the fuel feeding the flames.

Focusing on the base of the fire is part of the PASS technique: Pull the pin, Aim the nozzle, Squeeze the trigger, and Sweep from side to side at the base of the fire. This method ensures that the fire is tackled directly where it is strongest, increasing the chances of successfully putting it out.
