Which step follows 'Pull' in the PASS method for using a fire extinguisher?

Explanation:
The step after pulling the pin is to aim the extinguisher nozzle at the base of the fire. Aiming at the base targets the fuel source, which is where the fire continues to burn; directing the agent there is what stops the reaction effectively. If you aimed at the flames instead, you wouldn’t hit the area that needs cooling or smothering, so the effort would be much less effective. After aiming, you squeeze the lever to release the agent and then sweep the nozzle from side to side at the base to blanket the area and prevent reignition. This order ensures the extinguishing agent reaches the right spot and works efficiently.
