What the listings tell you
Fire ratings
Fire ratings tell you what each extinguisher is rated to fight. The First Alert is UL rated 1-A:10-B:C and fights wood, paper, trash, plastics, gasoline, oil and electrical-equipment fires. The Kidde is rated 2-A:10-B:C for trash, wood, paper, liquids, gases and electrical equipment, with a 13 to 15 second discharge time, a 12 to 18 foot discharge range and 100 PSI operating pressure. The LifeSafe spray covers 10 fire types including electrical, cooking oil, textiles, petrol and diesel, paper and card, motor oil and bio-ethanol, and is rated safe on electrical fires up to 1000V. The two Ougist sprays are water-based and cover grease, electrical, trash and wood fires, per the listings, with a 13-foot spray distance.
Lithium-ion battery fires
Makerspaces charge phones, laptops and e-scooter batteries, and lithium-ion fires need the right agent. The LifeSafe listing states its spray extinguishes lithium-ion battery fires. The First Alert and Kidde are ABC dry chemical units rated for electrical-equipment fires, which covers the electrical side. The Ougist sprays are water-based and list electrical fires among their coverage. For a space with charging stations, the LifeSafe’s stated lithium-ion coverage is the standout.
Size, mounting and warranties
The First Alert is a traditional extinguisher with all-metal construction, a commercial-grade metal valve and trigger, and a secure mount, bracket and strap included. The Kidde is a 4-pound unit with an all-metal valve assembly, an easy-read pressure gauge and a UL-approved wall hanger included. The LifeSafe is a compact 9.9-ounce spray. The Ougist 21oz is a 1.85-pound portable spray, and the Ougist 2-pack is two 620ml sprays with wall mounts. Warranties: the First Alert states a 10-year limited warranty, the Kidde a 6-year limited warranty, the Ougist 21oz a 5-year warranty, and the Ougist 2-pack states only a manufacturer and seller combination warranty with no term, which is not a concrete term. The LifeSafe listing states no warranty term.
Buying guide: best fire extinguisher for makerspace under 50
ABC dry chemical vs spray
ABC dry chemical extinguishers like the First Alert and Kidde fight the widest range of fires with a single unit and carry UL ratings. Sprays like the LifeSafe and Ougist are compact, leave less mess and are easier to grab, but cover smaller fires. For a makerspace, the common setup is a full-size ABC unit mounted by the door plus a compact spray at the workbench. The First Alert and Kidde cover the door, while the Ougist sprays or the LifeSafe cover the bench where small flare-ups start.
Where to mount it
Mount the extinguisher where you can reach it without crossing the fire: by the exit, not behind the laser. The First Alert includes a mount, bracket and strap, the Kidde includes a wall hanger, and the Ougist 2-pack includes wall mounts. The compact sprays fit in a drawer or on a shelf at the bench. Check the pressure gauge monthly: the First Alert and Kidde both list easy-read gauges.
Under 50 and what that buys
The under 50 tier buys reliable ABC extinguishers and compact sprays, not commercial systems. The First Alert and Kidde bring UL ratings and multi-year warranties at this tier, while the sprays trade rating for portability and clean-up. For the price of one dinner out, a makerspace gets real fire coverage.
