What does the acronym PASS stand for in fire extinguisher usage?

The acronym PASS stands for Pull, Aim, Squeeze, Sweep, which outlines the proper steps for using a fire extinguisher effectively.

Starting with "Pull," this refers to removing the safety pin from the extinguisher handle, which allows you to activate the device. Next, "Aim" directs you to point the extinguisher nozzle at the base of the fire, as targeting the base is crucial for effectively extinguishing the flames. Following that, "Squeeze" instructs you to compress the handle, releasing the extinguishing agent. Lastly, "Sweep" focuses on moving the nozzle side to side at the base of the fire while continuing to apply the agent until the fire is completely out.

This method is designed to maximize the effectiveness of the fire extinguisher and ensure safety while fighting a fire. The other options do not accurately recall the standard procedure taught for fire extinguisher use, making them less effective guidelines in an emergency situation.
