What is the first step in using a fire extinguisher, according to the fire safety standards?

The correct step in using a fire extinguisher is to pull the pin. This action is essential because the pin acts as a safety mechanism to prevent accidental discharge of the extinguisher. Pulling the pin allows the user to activate the extinguisher and use it effectively. Once the pin is removed, the extinguisher can be operated properly, making it ready for use against the fire.

Understanding fire safety standards emphasizes that following the correct sequence of actions is crucial for effective fire suppression. Recognizing that you first must remove the pin helps ensure users don’t attempt to squeeze or aim before the extinguisher is ready to be activated. This foundational step sets the stage for safely and efficiently directing the flow of extinguishing agent toward the fire when the other steps—aiming the nozzle at the base of the flames and squeezing the handle—are undertaken.
