Can You Reuse Fire Extinguishers?

It can happen quickly and spread rapidly. Fires happen most often in home kitchens, garages and around campfires or craft projects that use flammable adhesives or tools. Having a fire extinguisher at the ready can snuff out a hot mess that pops up unexpectedly before it turns into a tragedy. After the life-saving device is mounted to a wall, you should be prepared to use it. Once used, it will need to be recharged.

Types of Fire Extinguishers

It's good to know what type of fire extinguisher you need for your use, either for the kitchen, garage, boat or camping. Fire extinguisher types include Class A, B, C and D. Each is designed to put out a specific type of fire. Class A fire extinguishers are meant for ordinary combustibles, which is wood, cloth, paper, rubber and plastics that are typically found around the home. Class B involves flammable liquids, such as oil and grease fires from stovetop cooking, tars, oil-based paints and flammable gases that may be stored in a home. Class C fires are electrical in nature and can involve equipment, wire shortages and overheated appliances. Class D extinguishers are used for flammable metals. There are many fire extinguisher classes available, both online and at area fire stations, schools, libraries or private club functions.

How to Recharge a Fire Extinguisher

A fire extinguisher can be used more than once, depending on the brand and type. Once the fire extinguisher has been used, even for a small amount of time, it should be recharged or refilled. Once the pin has been pulled and the trigger depressed, the canister can lose pressure, making the extinguisher useless in the case of a future emergency. For household fire extinguishers, they need to be inspected and possibly recharged every six to 12 years, whether or not they've ever been used. This can be done at a certified fire equipment dealer or a firehouse.

Facts About Fire Extinguishers

There are many small things to understand about using a fire extinguisher. A fire extinguisher will spray a dry chemical stream from 5 to 20 feet. They usually contain 10 to 20 pounds of the dry chemical. That amount can be used up between 10 and 25 seconds. Once you release the trigger, the spray will stop. One-time-use fire extinguishers are smaller and are typically used for emergencies that can occur quickly, such as around a campfire or kitchen stove.

Steps to Use a Fire Extinguisher

Once you have the fire extinguisher out of its holder, hold it by its handle with the nozzle facing away from you or anyone around you. Just below the trigger is a pin. Pull the pin and aim the extinguisher at the fire at a low angle. This will release the dry chemical stream. Be sure to stand 10 feet from the fire. The extinguisher should be able to do its job safely from that distance. Point the stream at the lowest point of the fire that's closest to you. The extinguisher is meant to be held upright, as in horizontally. Don't angle it toward a fire. The stream will be angled when it exits the extinguisher. If it's a large extinguisher, place it on the floor. When you squeeze the trigger, do it slowly to release the CO2. Sweep the spray from side to side to get the best coverage. When remembering how to use a fire extinguisher, think of PASS. Pull the pin. Aim low. Squeeze the trigger slowly. Pull. Aim. Squeeze. Slow.
