How To Choose The Right Fire Extinguisher in Australia
To choose the right fire extinguisher, identify what’s most likely to catch fire in your location, match that to an Australian fire class (A–F), then select the extinguisher type rated for that class. For most Australian homes, a 2.5kg ABE dry chemical extinguisher covers the main risks. Kitchens need a wet chemical extinguisher. Server rooms and electrical switch rooms need CO2.
Step 1 — Identify Your Fire Hazards
Start by thinking about what combustible materials exist in your space:
- Wood, paper, fabric, cardboard — found in most homes and offices
- Petrol, solvents, paint, oil — common in garages, workshops, service stations
- Cooking oil, deep fryer fat — kitchens and commercial food preparation
- Electrical equipment — computers, switchboards, servers, appliances
- Flammable gases — LPG cylinders, industrial gas, propane
Most locations have more than one hazard type — which is why ABE dry chemical extinguishers are so widely used. They cover multiple fire classes in one unit.
Step 2 — Match Your Hazards to a Fire Class
| Fire Hazard | Fire Class | Extinguisher Type Needed |
|---|---|---|
| Wood, paper, fabric, cardboard | Class A | ABE dry chemical, water, or foam |
| Petrol, paint, solvents, oils | Class B | ABE dry chemical, CO2, or foam |
| LPG, propane, butane | Class C | ABE dry chemical only |
| Electrical equipment, computers, servers | Class E | CO2 (preferred) or ABE dry chemical |
| Cooking oils, deep fryer fat | Class F | Wet chemical only |
Step 3 — Choose by Location
Home
A 2.5kg ABE dry chemical extinguisher is the right choice for most Australian homes. It covers Class A (wood, fabric), Class B (flammable liquids), and Class E (electrical) — the three most common residential fire risks.
Mount it on the wall in an accessible spot outside the kitchen — not inside, where a fire could block access to it. If your home has a garage or workshop, add a second unit there.

Kitchen / Commercial Kitchen
Cooking oil fires (Class F) cannot be safely put out with a standard ABE extinguisher — the force of discharge can splash burning oil and significantly spread the fire. You need a wet chemical extinguisher (oatmeal/beige band). Commercial kitchens are required under Australian Standards to have wet chemical extinguishers installed.
- Home kitchen: 2L wet chemical
- Commercial kitchen / restaurant: 7L wet chemical — positioned near the exit, not directly beside the cooker

Office
Offices typically have Class A hazards (paper, furniture) and Class E hazards (computers, electrical). A 2.5kg ABE dry chemical extinguisher covers both. If your office has a dedicated server room, add a CO2 extinguisher for that space — CO2 leaves no powder residue that could damage equipment.

Server Room / Data Centre
CO2 is the correct choice for server rooms and data centres. It displaces oxygen to extinguish the fire and leaves zero residue — critical for protecting electronic equipment. Note: CO2 is a suffocation hazard in confined spaces, so ensure adequate ventilation and consider an automated suppression system for large server rooms.
- 3.5kg CO2 — small server cabinet or single rack
- 5kg CO2 — dedicated server room or multiple racks
Warehouse / Workshop
Warehouses and workshops have mixed hazards — flammable liquids, electrical equipment, and combustible materials all in one space. A 4.5kg or 9kg ABE dry chemical extinguisher is the standard recommendation. Larger spaces need multiple units — Australian Standard AS 1851 recommends extinguishers spaced no more than 15 metres apart.

Car / Vehicle
Vehicles need a compact extinguisher that handles fuel, oil, and electrical fires. The most popular sizes for passenger vehicles are 1kg (with hose), 1.5kg, and 2kg ABE dry chemical. A 2.5kg is the right choice for 4WDs, caravans, and commercial vehicles.
Choosing the Right Size
| Size | Best For |
|---|---|
| 1kg ABE (with hose) | Vehicles, caravans, small boats |
| 1.5kg / 2kg ABE | Vehicles, motorcycles, small spaces |
| 2.5kg ABE | Home, small office, vehicle — most popular size |
| 4.5kg ABE | Garage, mid-size office, light commercial |
| 9kg ABE | Warehouse, large commercial, industrial |
| 3.5kg CO2 | Server cabinet, small electrical room |
| 5kg CO2 | Server room, data centre |
| 2L wet chemical | Home kitchen |
| 7L wet chemical | Commercial kitchen, restaurant |
Australian Standards: What You Need to Know
Three Australian Standards govern fire extinguisher selection, installation, and maintenance:
- AS/NZS 1841 — The product standard. All extinguishers sold in Australia must be certified to this standard. It defines fire classes, extinguisher types, colour coding, and performance ratings.
- AS 2444 — Covers the selection and placement of portable fire extinguishers. This is the standard that determines how many extinguishers a building needs, what types, and where they must be located. It applies to all commercial and industrial premises.
- AS 1851 — The maintenance standard. Requires all installed extinguishers to be inspected and serviced every 6 months by a licensed fire protection technician. Businesses are legally required to comply.
Residential requirements vary by state, but a working extinguisher is strongly recommended for every home regardless of any legal obligation.
For a full breakdown of each extinguisher type, how they work, and their colour codes, see our guide to fire extinguisher types and fire classes.
Apartments, Units and Strata Buildings
Individual apartments and units within a strata building are generally covered by the building’s fire safety system — extinguishers in common areas (corridors, car parks, plant rooms) are the responsibility of the strata manager or body corporate, and must comply with AS 2444 and be serviced under AS 1851.
However, keeping a personal extinguisher inside your apartment is strongly recommended for the period before a fire grows large enough to trigger the building system:
- Inside the unit: 1kg or 2.5kg ABE dry chemical — compact, covers electrical and common combustibles
- Kitchen: 1kg or 2L wet chemical if you cook frequently with oils — never use ABE on a cooking oil fire
If you manage a strata building or commercial tenancy and need a formal fire safety assessment, this must be carried out by a licensed fire protection technician under AS 2444.
Frequently Asked Questions
What is the best fire extinguisher for home use in Australia?
A 2.5kg ABE dry chemical fire extinguisher is the best all-round choice for Australian homes. It covers Class A (wood, fabric), Class B (flammable liquids), and Class E (electrical) — the three most common residential fire risks. Place it outside the kitchen in an easily accessible location.
Can I use a dry powder extinguisher on a kitchen fire?
You can use ABE dry powder on a small Class A kitchen fire (e.g. a burning tea towel or chopping board). However, never use it on a cooking oil or deep-fryer fire (Class F) — the force of discharge can splash burning oil and significantly spread the fire. Use a wet chemical extinguisher for all cooking oil fires.
How many fire extinguishers do I need?
For residential homes, the minimum recommendation is one per floor, with an additional unit near the kitchen exit. For businesses, AS 2444 (selection and placement standard) sets out the requirements — generally extinguishers must be no more than 15 metres apart in commercial premises. The exact number depends on floor area, fire risk level, and the types of materials present. A licensed fire technician can carry out a formal AS 2444 assessment.
Do fire extinguishers need to be serviced?
Yes. All fire extinguishers in Australia must be serviced every 6 months by a licensed fire technician under AS 1851. You should also check the pressure gauge yourself monthly — if the needle is in the red zone, the extinguisher needs recharging immediately regardless of its last service date.
What size fire extinguisher do I need for my car?
A 1kg (with hose), 1.5kg, or 2kg ABE dry chemical extinguisher is the recommended size for most passenger vehicles. Mount it under the seat or in the boot with a proper bracket so it can’t become a projectile in an accident. For 4WDs, caravans, and commercial vehicles, a 2.5kg unit is preferred.
