Fire Extinguisher Types & Uses: A Dubai Guide
Fires are grouped by class: ordinary combustibles, flammable liquids, flammable gases, electrical equipment, cooking oils and metals. The main extinguisher types — dry powder (ABC), CO2, foam, water and wet chemical — each suit particular classes. Dry powder is versatile, CO2 suits electrical risk, wet chemical is for kitchen cooking-oil fires. The right unit depends on the hazard beside it.

Fires come in classes
Before you can pick an extinguisher you have to name the fire. Fire classes group hazards by what is burning, and each class behaves differently — which is why one extinguisher cannot safely cover them all.
- Ordinary combustibles: wood, paper, cloth, most furniture.
- Flammable liquids and gases: fuels, solvents, LPG.
- Electrical equipment: panels, servers, appliances live.
- Cooking oils and fats: kitchen and canteen hazards.
- Flammable metals: specialist industrial contexts.
What each extinguisher is for
Each agent puts out fire in a different way, so each one fits certain classes and is wrong for others. The goal is not the "best" extinguisher — it is the right one for the hazard standing next to it.
- Dry powder (ABC): versatile across common mixed risks.
- CO2: electrical equipment, leaves no residue.
- Foam: flammable liquids and ordinary combustibles.
- Water: ordinary combustibles only — never electrical.
- Wet chemical: cooking-oil fires in kitchens.
Matching units to your actual rooms
A real building is a patchwork of hazards — a server room, a kitchen, a workshop, a car park. QSERV walks the site and specifies the right type and size for each area, rather than filling the building with one generic unit that fits nothing perfectly.
- Site walk to identify the hazard in each area.
- CO2 near electrical rooms and IT equipment.
- Wet chemical in commercial kitchens.
- Correct type and size specified per location.
- Suitability recorded in the asset register.

Frequently Asked Questions
Plain answers on choosing the right extinguisher type for each hazard.
What are the main types of fire extinguisher used in Dubai?
The common types are dry powder (ABC), CO2, foam, water and wet chemical. Dry powder is versatile, CO2 suits electrical risk, foam and water cover ordinary combustibles and liquids, and wet chemical is made for kitchen cooking-oil fires.
Which extinguisher should I use on an electrical fire?
CO2 is the usual choice for electrical equipment because it leaves no residue and does not conduct like water. Never use a water extinguisher on live electrical equipment. Dry powder can also be suitable depending on the setting.
What is the difference between ABC dry powder and CO2?
ABC dry powder is versatile across mixed common risks but leaves a residue that can damage electronics. CO2 is cleaner and better suited to electrical and IT areas but has a shorter reach and does not cool as well on solid materials.
What extinguisher is needed in a commercial kitchen?
Wet chemical extinguishers are designed for cooking-oil and fat fires, which behave differently from other flammable liquids. Kitchens usually also have a fixed suppression system, but the correct portable extinguisher still matters.
Can one extinguisher type cover a whole building?
Not safely. A building has different hazards in different rooms — electrical, kitchen, storage, workshop — and each needs the right type. Filling a building with one generic unit leaves some areas poorly matched to their real risk.
Can QSERV tell me which extinguishers my site needs?
Yes. QSERV walks the site, identifies the hazard in each area, and specifies the correct extinguisher type and size per location, recording the suitability in the asset register so future checks confirm the right unit is in the right place.
