What should you do first when using a fire extinguisher?

When using a fire extinguisher, the first step is to pull the pin. This action is crucial because the pin serves as a safety feature that prevents accidental discharge of the extinguisher. Once the pin is removed, the extinguisher is ready for use, allowing you to proceed with the next steps: aiming the nozzle, squeezing the handle to discharge the agent, and sweeping it from side to side to effectively cover the fire.

Understanding the correct order of operations is essential for using a fire extinguisher safely and effectively in an emergency situation. Each step has a purpose that contributes to successfully extinguishing the fire while minimizing danger to yourself and others.
