What is the correct sequence for using a fire extinguisher?

The correct sequence for using a fire extinguisher is often summarized by the acronyms learned in safety training, with the sequence being Pull, Aim, Squeeze, and Sweep.

First, you pull the pin on the extinguisher to unlock it. This is a crucial first step, as the pin secures the handle and prevents accidental discharge. Once the pin is pulled, you aim the nozzle at the base of the fire. Aiming at the base is essential because that is where the fuel source is located, and targeting the flames themselves may not effectively extinguish the fire.

Then, you squeeze the handle. This action releases the extinguishing agent, allowing it to effectively combat the flames. Lastly, you sweep the nozzle from side to side at the base of the fire as you discharge the agent. Sweeping helps cover the area and ensures that the extinguishing agent reaches all parts of the burning material.

This sequence is designed to maximize effectiveness and safety when operating a fire extinguisher, ensuring that users can respond quickly and efficiently in case of a fire emergency. Understanding this order is critical in fire safety protocols.
