Position yourself with your back to an unobstructed exit so that you can get out quickly if you need to. The discharge range for extinguishers can run from 2-7 meters (know your extinguisher’s range beforehand), and you want to be far enough away to not be in danger of being burned, and close enough that the discharge will be effective.
The fire extinguisher step method is known as PASS, and each letter in the word PASS (P, A, S, and S) stands for the first word of each step. The PASS method works for many common fire extinguishers.
1. Pull the pin. This will allow you to discharge the extinguisher.
Many fire extinguishers have a pin near the handle at the top. Begin by removing that pin.
2. Aim at the base of the fire. If you aim into the flames, this won’t put out the fire.
3. Squeeze the top handle or lever. This depresses a button that releases the pressurized extinguishing agent in the extinguisher.
4. Sweep from side to side until the fire is completely out. Start using the extinguisher from a safe distance away, and then move forward. Once the fire is out, keep an eye on the area in case it re-ignites.
Step 4: When to Quit Fighting the Fire and Evacuate the Fire Scene
When you’re actively fighting the fire, you should remember there may be cases when you’ll have to give up, quit fighting the fire, and evacuate the fire area for your own safety.
Here are some reasons to quit fighting a fire and to evacuate immediately:
- The fire is spreading too quickly.
- The fire could block your only exit.
- The fire is too large.
- The fire is so hot you can’t get close enough to fight it effectively (3-4.5 metres).
- You’ve had to get down on your knees and/or crawl because you can’t see well otherwise, because of high temperatures, or because of smoke.
Once you’ve left the fire area, make sure a fire alarm has been triggered (if it hasn’t already).
