Fire extinguishers can be invaluable tools to help fight smaller fires in the workplace or to protect evacuation routes in the event of a larger one. It’s true that using a fire extinguisher isn’t rocket science by any stretch, but there are a few basics you need to be aware of before using it. It’s important to know what type of fire you’re trying to put out so that you can be sure to use the right type of fire extinguishers. Fire extinguishers come in a wide variety of types — each one designed to put out a different kind of fire.
To employ the extinguisher with proper technique, just remember the acronym “PASS.”
Pull the pin- Begin by removing that pin. In some cases, instead of a pin there’s been a lock latch you’ll have to release or a puncture level you have to press.
Aim the nozzle at the base of the fire- Hitting the tops of the flame with the extinguisher won’t be effective. You got to smother the sucker at its base.
Squeeze the trigger- In a controlled manner; squeeze the trigger to release the agent.
