    Why You Should Replace Your Fire Extinguishers

    Almost half of people in a recent CR study had extinguishers that were at least 20 years old, and many of the devices showed signs of wear and tear

    CR recently enrolled 68 of our members—all owners of fire extinguishers—in a research study to examine and test the extinguishers in their homes. 

    We found that many people might not realize how old their devices are. Almost half of the extinguishers were 20 or more years old, though those devices typically have a life span of only 12 years. 

    More on Fire Safety

    Eighteen participants also noted at least one visible problem with their extinguisher, such as low-pressure readings, rust, scratches, or dents. Three of these participants said there was some kind of issue with the pull-pin. 

    The good news: Of the 60 participants who tried to discharge their extinguishers, only three found that they failed to let out any extinguishing agent.

    Here’s what you need to know about buying and using extinguishers.

    • Have at least one extinguisher rated “ABC” per floor. That means it’s designed to handle most small home fires, including those from wood, paper, or flammable liquids, as well as electrical fires. Don’t forget to put one in your basement and garage. 

    • In the kitchen, have one near but not next to your stove. Smoke or fire from the appliance could block access to the device. Also, avoid storing it under a sink: Moisture could damage it. One with just a B on its label is okay because it will work on oil and grease fires. 

    • Get the largest extinguisher you can safely handle. Five to 10 pounds is common. 

    • If you need to deploy your extinguisher, use the PASS method. With your back to an exit, Pull the pin, Aim the nozzle toward the base of the fire, Squeeze the trigger, and Sweep from side to side.
