Kidde Basic 110 Fire Extinguisher for HomeView on Amazon
You bought the laser to make things: signs, tumblers, leather patches, cut parts. The one tool you hope never to use is also the one your insurance, your lease and your common sense all ask about. The best fire extinguisher for home workshop setups is the one that covers the fires your materials can start: wood, paper and cardboard, plus the electrical side of the machine itself. These five are all ABC dry chemical units, from a long-warranty rechargeable to a 2-pack of basics. For each one we list what the listing states and say plainly what it does not.

Class ratings, in plain words
Every pick here is an ABC dry chemical extinguisher: Class A for wood, paper, cloth and trash, Class B for flammable liquids, Class C for live electrical equipment. The numbers are the rating sizes: the Kidde Pro 340 lists 3A:40-B:C, the First Alert and Amerex list 2-A:10-B:C, and the Kidde Basic and Ougist list 1-A:10-B:C. Bigger numbers mean a bigger rated fire, and the Pro 340 is the biggest rated pick here by a clear margin.
Buying guide: the best fire extinguisher for home workshop setups
Rechargeable or single-use
The First Alert HOME2PRO, Kidde Pro 340 and Amerex B500 are rechargeable by a certified technician after use, per their listings. The Kidde Basic 110 is single-use only, per its bullets: once discharged, you replace it. For a workshop you actually work in, a rechargeable unit is the longer-term pick.
Size and agent weight
The Kidde Pro 340 lists 5.5 lb of dry chemical agent, the Amerex lists 5 lb, and the Kidde Basic and Ougist list 2.5 lb each. Bigger agent weight means longer knockdown time on paper and wood fires, the exact fires a laser workshop worries about.
Discharge time and range
The Kidde Pro 340 lists a 13 to 15 second discharge with a 12 to 18 foot range at 195 PSI, and the Amerex lists a 14 second discharge with a 12 to 18 foot range. The others state no discharge figures, so compare them on ratings and warranty instead.
Warranty
The First Alert lists a 12-year limited warranty, the longest here. Both Kidde listings state a 6-year limited warranty. The Amerex and Ougist listings state no warranty term, so they score zero on warranty.
How discharge time and range change the math
Two numbers decide how an extinguisher behaves in a real fire: how long it discharges and how far the stream reaches. The Kidde Pro 340 lists a 13 to 15 second discharge with a 12 to 18 foot range at 195 PSI, and the Amerex B500 lists a 14 second discharge with a 12 to 18 foot range. That means roughly the same working time on both: about a quarter of a minute to knock down flames while standing back from heat and smoke. The three picks that state no discharge figures cannot be compared on this axis, which is itself useful information: a listing that omits discharge time is asking you to buy on rating alone.
Range matters because you fight the fire from where you stand. Twelve to 18 feet keeps you out of the heat zone while the stream still reaches the seat of the fire. In a home workshop, measure the distance from your mounted extinguisher to the laser: if it is farther than the stated range, move the extinguisher closer or add a second unit. The Kidde Basic 110 is sold as a 2-pack for exactly this reason, and at 3.25 x 4.65 x 14.2 in per unit it mounts easily near both the machine and the exit.
Placement and mounting in a home workshop
An extinguisher you cannot reach in seconds is decoration. Mount one near the laser and one near the exit, so a fire between you and the machine never traps you. The Kidde Basic 110 includes a UL-approved plastic strap bracket, the Kidde Pro 340 includes a UL-approved metal wall hanger, and the First Alert HOME2PRO includes a mounting bracket, per their listings. The Amerex is wall-mountable with a standard bracket, and the Ougist ships with self-adhesive mounting accessories.
Weight decides who can use it. The Kidde Pro 340 weighs 8.95 lb, the First Alert 9.6 lb, the Ougist 4.4 lb and the Amerex 5 lb per unit. In a household where different people may need to grab it, a lighter unit like the Ougist or the Amerex is easier to lift and aim one-handed, while the heavier Kidde Pro trades weight for the biggest agent load. Agent weight is the other half of the story: the Pro 340 carries 5.5 lb of dry chemical, the Amerex 5 lb, and the Kidde Basic and Ougist 2.5 lb each.
Project Match

- One for the shop, one for the house: Kidde Basic 110, a 2-pack of 1-A:10-B:C units, UL Listed.
- Commercial-grade 2-pack: Amerex B500, UL and ULC listed with a 14 second discharge and 12 to 18 foot range.
- Compact extra for the car or bench: Ougist FF1KG, 1-A:10-B:C at 4.4 lb with a monthly inspection card included.
How the scores add up
Each pick is scored out of 10 on performance, build, value, safety and warranty, using only what the listing publishes. The weights are on our How We Pick page. Safety scoring uses stated certifications and service features: UL listings, UL-approved hardware and rechargeable designs. The Amerex and Ougist listings state no warranty term, so they score zero on warranty.

FAQ: lasers and CNC
What class of extinguisher does a laser workshop need?
ABC dry chemical covers the three fire types a laser workshop sees: Class A for wood, paper and cardboard, Class B for flammable liquids, and Class C for the electrical side of the machine. All five picks are ABC units.
Should I get a rechargeable or single-use extinguisher?
Rechargeable, if the budget allows. The First Alert HOME2PRO, Kidde Pro 340 and Amerex B500 are rechargeable by a certified technician after use. The Kidde Basic 110 is single-use only, per its bullets, so a discharge means buying a replacement.
Where should the extinguisher go in a home workshop?
Near the exit, within quick reach of the laser, mounted on the wall. The Kidde Basic includes a UL-approved plastic strap bracket, the Kidde Pro includes a UL-approved metal wall hanger, and the First Alert includes a mounting bracket.
Do these need servicing?
Check the pressure gauge monthly: the listings for the Kidde Basic, Kidde Pro and First Alert describe an easy-to-read gauge where green means charged. The Ougist includes a monthly inspection record card. Rechargeable units are serviced by certified professionals.
