A blog post about occupational safety and fire extinguisher training isn’t likely to rank on many people’s favourite reading lists, but it might save your life. That alone should warrant a few minutes of your valuable time.

In this step-by-step guide, we will run through how to use a fire extinguisher, so you can tackle any fire that flares up in the future.

Using a Fire Extinguisher - Step by Step

There are three main types of fire extinguishers: water, foam, and dry powder. Each type has its own use cases, so it is important to use the right fire extinguisher for the flames you are dealing with.

Water fire extinguishers are best used on solid fuels such as wood or paper, while foam fire extinguishers are more effective on flammable liquids, such as when cooking appliances cause a fire. Dry powder fire extinguishers can be used on solid and liquid fires, but they are most effective on fires involving electrical equipment.

To use a fire extinguisher effectively, there are only a few crucial steps to remember, and all it takes is a simple acronym: PASS (pull-aim-squeeze-sweep)

Pull the Safety Pin:

To prevent unintentional discharge, the handle on top of the canister needs to have a pin passing through it. Take out this pin. Some fire extinguishers lack hooks and use a lock latch or pierce level instead. Before a fire starts, find out which one your extinguisher has.

Aim the Nozzle:

Hold the handle and the hose's end in one hand. To put out whatever is burning, aim the extinguisher nozzle at the source of the fire. A common error is to aim at the flames directly, which is useless.

Squeeze the Handle:

Depress the fire extinguisher's handle to release a stream of fire suppressant through the hose and out the nozzle.

Sweep the Nozzle in a Side-to-Side Motion:

Use a sweeping motion to douse the fire once the suppressant starts to flow. Keep doing this until the flames seem to be extinguished completely. If the fire re-ignites, keep a close eye on the area for a few minutes for local fire departments and use the extinguisher again if required.

Common Errors To Avoid When Using A Fire Extinguisher

  • A fire extinguisher is your primary line of defence if there is a fire since it can stop the flames from spreading. However, there are a few errors that users of portable fire extinguishers commit. Although using a fire extinguisher is relatively simple, it is essential to learn the proper, efficient, and secure approach to extinguishing a fire. The following are common mistakes to avoid when using a fire extinguisher.

  • Not reading the instructions. Fire extinguishers have instructions on how to use them and what they should be used for. If you don't read those instructions, you could use the wrong extinguishing agent incorrectly.

  • Using water on an electrical fire. This could cause electrical shock or electrocution! Water is not recommended for electricity fires; instead, use CO2 or dry chemical extinguishers.

  • Not knowing where your fire extinguisher is located. A study found that only about half of people knew where their fire extinguisher was in an emergency. Ensure you know your location to access it quickly in an emergency.

  • Not knowing which type of fire extinguisher to use. Different types of fires require different types of extinguishers. For example, you need an ABC fire extinguisher if you have a grease fire. If you have a wood or paper fire, an ABCD fire extinguisher will be more effective. If you aren't sure what kind of extinguisher to buy, ask your local hardware store or call the fire department.

  • Another common mistake is not keeping your fire extinguishers up-to-date and fully charged with pressurized air. If you have been having trouble finding time to check on their condition or refill them, consider hiring a fire extinguisher maintenance professional who can manage this task for you so that you don't have to worry about it at all anymore.

  • Leaving a fire extinguisher in a place where it might freeze during winter (if it's an ABC-rated extinguisher). This could cause damage that renders it unusable. It's best to keep them inside, so they don't freeze up during these cold months!

  • Failing to check your fire extinguishers regularly (every 6 months) and replace their CO2 canisters every 12 years or so. Not doing this could cause them not to work properly when needed most.

The Bottom line

That's it. You've got all the information you need to know how to use a fire extinguisher. Safety is important, and fire extinguishers are a necessity. Ensure you have the right fire extinguishers for your home, office, or classroom. A little preparation goes a long way and could save your life. But remember that even the best fire extinguisher training does not make you a fully equipped firefighter, so always be aware of a safe evacuation path and evacuate immediately if a fire shows signs of burning out of control.
