Which of the following is a crucial step in the PASS method for using a fire extinguisher?

The PASS method is an acronym that stands for Pull, Aim, Squeeze, and Sweep. This method is crucial for effectively using a fire extinguisher in an emergency situation. The first step, which is to pull the pin or safety seal of the extinguisher, is essential because it allows the user to activate the extinguisher. Without pulling the pin, the extinguisher will not function, and the subsequent steps cannot be performed.

Understanding the order and significance of each step in the PASS method is vital for ensuring safety and effectiveness when using a fire extinguisher. The action of pulling the pin is the fundamental initial step that enables the user to proceed to aim at the base of the fire, squeeze the handle to release the agent, and finally sweep the nozzle from side to side to cover the area of the fire.
