Home fire extinguisher guide: which type you need, where to keep it and how to use it
Which fire extinguisher to choose for an apartment, house, kitchen or car: ABC dry chemical, foam, CO2 or kitchen (Class K/F). Fire classes, the PASS method, when not to fight a fire and how to check your extinguisher.
In short
- For most homes, a multipurpose ABC extinguisher (5 lb or larger in the US, 6 kg in Europe) is the right choice. Add a fire blanket in the kitchen.
- Keep it near an exit, not next to the fire hazard: you should grab it on your way to the door.
- Only fight a small, just-started fire, and only with your exit behind you. Otherwise, get out and call for help.
- PASS: Pull the pin, Aim at the base, Squeeze the handle, Sweep side to side.
House fires usually start small: a pan of oil, an overheated extension cord, a forgotten candle. In the first 30–60 seconds an extinguisher can stop one. After a few minutes, the only option is to get out. That’s why it matters to have the right extinguisher in the right place and know how to use it without reading the label.
Fire classes
Every extinguisher label shows which fire classes it’s rated for. The letters differ slightly between the US and Europe:
| What burns | US class | Europe class | Examples |
|---|---|---|---|
| Ordinary solids | A | A | Wood, paper, fabric, plastic |
| Flammable liquids | B | B | Gasoline, solvents, paint |
| Flammable gases | (B) | C | Natural gas, propane |
| Live electrical equipment | C | (pictogram) | Appliances, wiring |
| Cooking oils and fats | K | F | Pan or deep-fryer fires |
Which type to choose
| Type | Rated for | Pros | Cons | Where |
|---|---|---|---|---|
| ABC dry chemical | A, B, C/electrical | All-round, inexpensive | Very messy, corrosive | Home, garage, car |
| Foam | A, B | Cleaner, cools | Not for cooking oil | Home, office |
| CO2 | B, electrical | No residue | Poor on Class A, very cold nozzle | Near computers, electrical panel |
| Wet chemical (K/F) | A, K/F | Made for cooking oil | Expensive | Kitchens with fryers |
| Fire blanket | Pan fires, clothing | Simple, cheap | Very small fires only | Kitchen |
Our recommendation for a typical home: one multipurpose ABC extinguisher near the exit on each floor, plus a fire blanket in the kitchen. Many fire services also suggest one in the garage.
Where to keep it
- Near an exit, in a hallway or by the front door: you grab it on the way out with your exit behind you.
- In plain sight, on a wall bracket, 3–5 ft (1–1.5 m) up.
- Not right next to the stove or other fire hazard: you may not be able to reach it.
- Fire blanket near the kitchen, but not above the stove.
How to use it: PASS
- Pull the pin, holding the extinguisher upright.
- Aim at the base of the fire, not the flames, from 6–10 ft (2–3 m).
- Squeeze the handle fully.
- Sweep side to side at the base until the fire is out. Move in slowly.
A typical home extinguisher empties in 10–20 seconds. There’s no time to experiment.
When not to fight it
Get out immediately and call the emergency number if:
- the fire is bigger than a wastebasket or spreading fast;
- the room is filling with smoke;
- your exit isn’t behind you;
- you don’t know what’s burning or don’t have the right extinguisher;
- the extinguisher is empty and the fire isn’t out.
Close the door behind you: it slows the fire. What to do next is in our house fire guide.
Checks
- Monthly: gauge needle in the green, seal intact, hose not cracked.
- Yearly: professional inspection, or as the manufacturer recommends.
- After any use: recharge or replace, even if you used it for a second.
An extinguisher goes hand in hand with a smoke alarm: the alarm warns you, the extinguisher gives you a chance to stop the fire while it’s small.

Frequently asked questions
Can I put out a grease fire with water?
Never. Water instantly turns to steam and throws burning oil across the kitchen. Turn off the burner, cover the pan with a lid or fire blanket, and leave it covered until cool. Water and standard foam extinguishers aren't for cooking oil either; that's what Class K (US) or Class F (Europe) extinguishers are for.
Does dry chemical powder damage appliances?
The powder is fine, corrosive and hard to clean. For a small fire that's a small price, but around TVs and computers a CO2 extinguisher or a foam rated for electrical equipment makes less mess.
How long does an extinguisher last and who checks it?
Check the gauge (needle in the green) and the seal monthly. Many fire services recommend an annual professional inspection, and rechargeable units need servicing at intervals set by the manufacturer. Any extinguisher that has been used, even briefly, must be recharged or replaced. Disposable units typically last about 10–12 years.
Do I need one in my car?
It's required in some countries (including Romania and several others in Europe) and a good idea everywhere. Choose a small ABC unit, mount it so it can't roll around and check the date. See also our car emergency kit guide.
