What the rating labels mean
Every residential fire extinguisher carries a class rating that tells you which types of fires it handles. The correct choice for most homes is an ABC dry chemical extinguisher. The letters indicate fire class coverage, and the numbers indicate extinguishing capacity within each class.
Class A: ordinary combustibles
Wood, paper, cloth, trash, and most solid organic materials. The "A" number (1A, 2A) is equivalent to 1.25 gallons of water per unit. A 2A rating has roughly twice the Class A firefighting capacity of a 1A.
Class B: flammable liquids and gases
Gasoline, cooking oil, grease, propane. The "B" number indicates square footage of suppression capacity: 10-B covers approximately 10 square feet of burning liquid. Kitchen fires and garage fires are typically Class B.
Class C: energized electrical equipment
Appliances, wiring, circuit breakers, and any fire involving live electrical current. The "C" designation means the extinguishing agent is non-conductive and safe to use on electrical fires. There is no number. Either the agent is non-conductive or it is not.
For most homes, a minimum 1A:10-B:C rating is adequate. A 2A:10-B:C extinguisher provides meaningfully better Class A coverage and is the better choice for kitchens and garages where fires are most likely to start.

Where to put it
In the kitchen: mount near the exit, not above or next to the stove. If the stove is on fire, you need to be able to reach the extinguisher without getting between yourself and the flames. A drawer or cabinet near the kitchen door is a common placement. Eye level or slightly below is correct so you can grab it quickly in dim or smoky conditions.
For a multi-floor home, one extinguisher per floor provides adequate coverage. The garage is a high-risk location: gasoline, propane, power tools, and stored chemicals create a combination of Class A and Class B fire hazards. A dedicated extinguisher mounted inside the garage door or near the door to the house is standard.
Every person in the household old enough to operate the extinguisher should know exactly where it is and be able to find it in the dark. Knowing where it is before a fire starts is most of the preparation.
How to use it: the PASS method
Pull the pin
Break the tamper seal and pull the pin from the handle. This unlocks the operating lever.
Aim at the base
Point the nozzle or hose at the base of the fire, not the flames. You are suppressing the fuel source, not the visible fire above it.
Squeeze the handle
Squeeze the handle lever steadily. Most residential extinguishers discharge for 10 to 15 seconds total. Use that time efficiently.
Sweep side to side
Move the nozzle in a slow, controlled sweep across the base of the fire as you advance toward it. When the flames are out, watch for re-ignition and be ready to discharge again.
When to stop and leave
A residential fire extinguisher is effective on small, contained fires in the first 30 seconds. If any of the following are true, do not attempt to fight the fire. Get out, close the door behind you, and call 911 from outside.
The fire is larger than a waste basket
The room is filling with smoke or the smoke is dark and dense
You do not have a clear escape route with your back to an exit
The extinguisher empties before the fire is out
You are unsure of the fire type or whether it involves electrical wiring inside a wall
Inspection and replacement
Check the pressure gauge once a month. The needle should be in the green zone. If the needle has dropped below green, the extinguisher is no longer fully pressurized and should be recharged or replaced.
After any use, even partial discharge, have the extinguisher professionally recharged or replace it. A partially discharged unit may not function reliably in the next incident.
Non-rechargeable units should be replaced 12 years from the manufacture date printed on the label. Rechargeable units should receive annual inspection by a certified professional and be replaced 12 years from manufacture.
NWS recommendation
Start with one First Alert HOME1 in the kitchen, mounted near the exit and away from the stove. If you have a garage, add a second. When budget allows, upgrade the kitchen unit to the Kidde Pro 210 for the higher 2A:10-B:C rating. More important than which model you buy is that every adult in the household knows where it is and has practiced the PASS method at least once.
