What is the first step in operating a fire extinguisher during an emergency?

The first step in operating a fire extinguisher during an emergency is to pull the safety pin. This action is crucial as it unlocks the extinguisher and allows you to activate it. Pulling the pin prevents accidental discharge and ensures that you have control over when to deploy the extinguisher. It’s designed to keep the handle in place until you are ready to use the extinguisher.

Once the pin is pulled, you can proceed to aim at the base of the fire, squeeze the handle, and remove the extinguisher from its mount, but these steps are only effective after the safety pin has been removed. Understanding this sequence is essential for proper extinguisher usage, as it directly influences safety and effectiveness during a fire emergency.
