What is the first step in using a fire extinguisher as per the P.A.S.S. method?

Using a fire extinguisher effectively requires following the P.A.S.S. method, which stands for Pull, Aim, Squeeze, and Sweep. The very first step is to pull the pin. This is crucial because the pin acts as a safety mechanism that prevents accidental discharge of the extinguisher. Pulling the pin allows you to access the extinguisher's handle and begin the process of putting out a fire.

Once the pin is removed, you can proceed to aim the nozzle at the base of the fire, squeeze the handle to release the extinguishing agent, and sweep the nozzle side to side to cover the area of the fire. Following this sequence ensures that you operate the extinguisher safely and effectively.
