Buying guide: the best fire extinguisher for gas fires
Class ratings
Class A covers ordinary combustibles such as wood and paper, class B covers flammable liquids and gases, class C covers electrical equipment, and class K covers cooking oils. For gas fires, the B rating is the one that matters: the Kidde home unit and the First Alert unit carry a 10-B rating, the Kidde vehicle unit carries a 5-B rating, while the AmzBoom sprays list classes A, B, C and K. Match the rating letters to the fuels in the garage before buying.
Size and placement
A 6-pack spreads units across rooms, while a single unit needs a chosen spot. The Kidde home listing gives dimensions of 15.0 by 9.38 by 10.63 inches, the First Alert unit measures 4.25 by 4.0 by 15.0 inches, and the Kidde vehicle unit measures 3.25 by 3.25 by 11.3 inches. The AmzBoom sprays are slimmer, at 3.15 by 3.15 by 10.8 inches for the 2-pack listing and 2.6 by 2.6 by 10.0 inches for the 3-pack listing. For the wider garage pick, see the best fire extinguisher for garage.
Single use, rechargeable and warranty
The Kidde home unit is residential, single use only, so a discharged unit must be replaced. The First Alert unit can be recharged by a certified professional after use, which suits a buyer who wants one unit for years. Warranty terms run 6 years on four picks and 10 years on the First Alert unit, so check the term on the listing before buying.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Measure the mounting spot before buying: the Kidde vehicle unit measures 3.25 by 3.25 by 11.3 inches, and the First Alert unit measures 4.25 by 4.0 by 15.0 inches.
- Keep one where fuel lives: the Kidde vehicle unit suits cars and trucks, and the AmzBoom sprays fit glove boxes and kitchen cabinets.
- Check the pressure indicator: the Kidde units and the First Alert unit carry an easy-to-read gauge or indicator, and an arrow in the green means charged.
- Check the warranty term on the listing: four picks carry a 6-year term and the First Alert unit carries a 10-year term.
- Plan for single use or recharge: the Kidde home unit is single use only, while the First Alert unit can be recharged by a certified professional after use.
