Which step in the P.A.S.S. technique involves moving the extinguisher from side to side?

The step in the P.A.S.S. technique that involves moving the extinguisher from side to side is the sweeping motion. This action is critical when using a fire extinguisher because it helps to effectively cover the area of the fire. When you aim the extinguisher at the base of the fire and then sweep from side to side, you are ensuring that the extinguishing agent effectively reaches all parts of the flames, maximizing the chances of extinguishing the fire.

This sweeping movement also helps prevent reignition by thoroughly soaking the fuel source, allowing the agent to suppress the fire effectively. It is important to remember that aiming directly at the base of the fire is essential for effectiveness, and the sweeping motion should be conducted until the fire is completely out.
