Buyer’s Guide
Take a look at how the factors below affect a fire extinguisher’s ability to put out a fire.
Class System
Fire extinguishers are given a rating to tell you what type of fire they’re capable of putting out. The canister should clearly indicate what class the extinguisher falls under with words and graphics.
- Class A: Class A extinguishers are used on fires that involve paper, wood, plastic, and other solids. The graphic on the canister should be a campfire or burning trash can.
- Class B: This type of extinguisher is used to put out flammable liquids and gases, including oil, gasoline, propane, and methane. The graphic for this class is a gas can.
- Class C: This type of fire extinguisher puts out electrical fires caused by appliances. Its graphic is a plug and an outlet.
- Class D: Class D extinguishers put out fires caused by flammable metals, such as aluminum, sodium, and magnesium. The graphic for this extinguisher is a gear.
- Class K: This extinguisher puts out cooking oil fires. It’s designed for professional kitchens in restaurants as opposed to households. The graphic for this class is a cooking pan on fire.
Material
Fire extinguishers have different materials that come out when you spray them.
- Dry chemical: This is the most common material found in residential extinguishers. It can put out Class A, B, and C fires.
- Carbon dioxide: Carbon dioxide discharges at cold temperatures and smothers fires, preventing them from getting more oxygen. This material is found in Class B and C extinguishers.
- Foam: Foam removes heat from the fire and prevents oxygen from reaching it. This is another common material used to put out residential fires.
- Liquified gas/clean agent: This material doesn’t leave a residue behind after use, which is why it’s sometimes called a clean agent extinguisher. It’s commonly found in Class B and C extinguishers and can sometimes be found in Class A models.
- Water: You won’t find many fire extinguishers that use water. The only reason firefighters are able to put out fires using water is because they use large volumes of it at high pressures. If you do find a residential extinguisher that contains water, it likely has foam mixed in with the water to work on Class A fires.
- Wet chemical: This type of extinguisher is mainly used in restaurants for Class K fires.
- Dry powder: This powder is only effective at putting out Class D fires, making it an uncommon material to find in residential fire extinguishers.
Size
There are four common sizes for residential fire extinguishers.
- 10-pound: This is the largest extinguisher you’ll find for home use. Ten-pound fire extinguishers typically cost $45-$100.
- Five-pound: This extinguisher costs between $30 and $75.
- Two-pound: A small, two-pound canister will cost around $20-$60.
- Stovetop: This is the smallest type of residential extinguisher. It costs $15-$50.
Maintenance
It’s recommended that you inspect your fire extinguisher at least once a year. Each fire extinguisher will have instructions printed on it that tell you how to inspect it, but most of these instructions involve inspecting the safety pin, nozzle, and valve for cracks and corrosion and the pressure gauge for charge. Some fire departments will also inspect your extinguisher for you if you want proof from an expert that it’s in working condition.
Frequently Asked Questions
What size fire extinguisher do I need?
Mid-sized extinguishers, such as two- and five-pound models, work well in kitchens and other rooms, and canister extinguishers work well for cars. You may want a 10-pound fire extinguisher for a garage or living room to put out large fires.
Can you reuse a fire extinguisher?
If your fire extinguisher isn’t expired and is labeled as reusable, you can refill it for $10-$25 after using it.
Can I test my fire extinguisher?
Some fire departments offer classes that allow you to test a fire extinguisher. This ensures that you know how to use one if you ever have to put out a real fire. If this sounds like something you’d be interested in, contact your local fire department.
