What does the PASS technique for using a fire extinguisher stand for?

The PASS technique is essential for effective use of a fire extinguisher in an emergency situation. It stands for Pull, Aim, Squeeze, and Sweep.

Pull involves removing the safety pin or break the seal of the fire extinguisher, which is necessary to activate the device. Aim directs the nozzle toward the base of the fire, where the fuel source is located rather than at the flames themselves, allowing for a more effective application of the extinguishing agent. Squeeze means to press the handle to release the extinguishing agent, and finally, Sweep refers to moving the nozzle from side to side at the base of the fire until it is completely out. This technique is designed to maximize the effectiveness of the extinguisher and ensure safety during firefighting efforts.

Understanding this sequence is critical for anyone who's trained to use a fire extinguisher, as it provides a clear, easy-to-remember method to follow under stressful conditions. The other options do not represent the established terminology or process for using a fire extinguisher, which could lead to confusion or incorrect usage in an emergency.
