Why the type of extinguisher matters
Fires burn different things, and each needs a different way to put it out. Spraying water on burning cooking oil can make it explode outwards. Spraying water on a live electrical panel can give you an electric shock. Choosing the right extinguisher keeps you safe.
Which extinguisher for which fire?
| What is burning | Examples | Use | Never use |
|---|---|---|---|
| Ordinary materials | Paper, wood, cloth, plastic | DCP (ABC), foam, water | - |
| Flammable liquids | Petrol, diesel, paint, thinner | Foam, DCP, CO2 | Water |
| Electrical equipment | DB panels, computers, generators | CO2, DCP | Water, foam |
| Cooking oil and fat | Kitchen fryers, woks | K-type (wet chemical) | Water |
The four main types
DCP (dry chemical powder)
Often just called a "powder" extinguisher. ABC-rated DCP works on ordinary materials, flammable liquids and electrical fires, so it is a good general choice for corridors, offices and parking. The downside: the powder makes a big mess and can damage electronics.
CO2 (carbon dioxide)
CO2 pushes away the oxygen a fire needs. It leaves no residue, so it is ideal for server rooms, electrical rooms, DB panels and generators. Do not hold the horn with bare hands, because it gets extremely cold.
Foam
Foam forms a blanket over burning liquids and cools ordinary materials. Good for fuel stores, workshops and parking areas.
K-type (wet chemical)
Made for commercial kitchens. It reacts with hot cooking oil to form a soapy layer that stops the fire from re-lighting. Every restaurant and food court kitchen should have one.
Where to place extinguishers
- Near exits and stairs on every floor, so people can grab one on their way out.
- CO2 next to electrical rooms, server rooms and generators.
- K-type in kitchens, close to the cooking area but not right behind it.
- Mounted on the wall at a height people can reach, with a sign above it.
How to use a fire extinguisher: remember PASS
- Pull the safety pin.
- Aim at the base of the fire, not the flames.
- Squeeze the handle.
- Sweep from side to side.
Only fight a small fire, and always keep your back to a clear exit. If the fire is growing, leave and call Rescue 1122.
Keep your extinguishers ready
Check each extinguisher every month: the pressure gauge needle should be in the green, the pin and seal should be in place, and nothing should block it. Get it serviced every year and refilled after any use, even a short one. See our full maintenance checklist.

Frequently asked questions
Which fire extinguisher is best for electrical fires?
CO2 is best for electrical equipment because it leaves no residue. DCP also works. Never use water or foam on live electrical equipment.
Which fire extinguisher should a restaurant kitchen have?
A K-type (wet chemical) extinguisher, which is made for cooking oil and fat fires. Never use water on an oil fire.
How often should fire extinguishers be checked?
Check them visually every month, have them serviced by a competent person every year, and refill them after any use. Cylinders also need pressure (hydrostatic) testing at set intervals, as set out in NFPA 10.
