The first action in this sequence is to pull the pin from the handle of the extinguisher. This step is crucial because the pin serves as a safety mechanism that prevents accidental discharge. By pulling the pin, the user disengages this safety feature, allowing them to use the extinguisher.

Following the pulling of the pin, the user should then aim the nozzle at the base of the fire, squeeze the lever to release the extinguishing agent, and sweep the nozzle from side to side. Each of these actions is designed to maximize the effectiveness of the extinguishing agent in suppressing the fire, while also ensuring the safety of the user.

The other options do not align with the PASS technique. Pointing the extinguisher at the ceiling would waste the extinguishing agent and be ineffective against the flames. Spraying in a horizontal line may also be inefficient, as it is essential to aim at the base of the fire for proper suppression. Aiming above the flames does not target the source of the fire, which is critical for extinguishing it effectively. Therefore, pulling the pin is
