Fire Extinguisher Selection Guide for the UAE

How fires are classified in the UAE (and why electrical is different)

The UAE follows the European fire-class convention defined in BS EN 2, which the UAE Fire and Life Safety Code of Practice builds on alongside NFPA, BS/EN and ISO references. Under this convention there are five fire classes — A, B, C, D and F — defined by what is burning.

The single most important concept to grasp is this: electrical fire is not a fuel class. A fire involving energized equipment is still classified by the fuel that is alight (the cable insulation, the plastic housing, nearby paper, and so on). What matters for electrical safety is whether the extinguishing agent is non-conductive. EN 3 extinguishers can be subjected to a dielectric (35 kV) test and, on passing, are marked as suitable for use on or near live equipment — typically rated safe up to about 1000 V at a 1 m distance, though the exact marking is product-specific and should be confirmed on the unit.

This differs sharply from the US NFPA convention, and the difference is dangerous if mixed up. Under EN/ISO (used in the UAE), Class C means flammable GASES. Under US NFPA 10, "Class C" means energized ELECTRICAL equipment, and flammable gases are not given a separate class (they are generally addressed under Class B). The same letter means different hazards in the two systems — always state which convention you are using. For agent supply, servicing and refilling across the Emirates, see our fire extinguishers page.

The full fire-class table (BS EN 2)

This is the authoritative fire-class table used in the UAE, with the suitable agent(s) for each class and a final row showing how electrical fires are handled.

Class	Fuel / fire type	Typical examples	Suitable extinguishing agent(s)
A	Ordinary combustible solids	Wood, paper, cardboard, textiles, most plastics	Water, foam, ABC dry powder, wet chemical (rated A)
B	Flammable / combustible liquids	Petrol, diesel, kerosene, paints, solvents, alcohols	Foam, ABC dry powder, CO², clean agent
C	Flammable gases	Propane (LPG), butane, methane / natural gas, acetylene	ABC dry powder — isolate the gas supply first; do not extinguish a gas jet unless the leak can be stopped
D	Combustible metals	Magnesium, sodium, potassium, titanium, aluminium swarf	Special Class D powder ONLY (e.g. ternary eutectic / graphite-based); standard agents are unsafe
F	Cooking oils and fats	Deep-fat fryer oil, lard, vegetable/animal cooking fats	Wet chemical (potassium-based) ONLY
(Electrical)	NOT a separate fuel class in EN/UAE convention	Energized equipment, switchgear, server hardware, cabling	Use a non-conductive agent: CO², clean agent, or dry powder. EN 3 units may carry a dielectric marking. Water and foam should not be used on live electrical equipment.

Note: some UAE-market and US-influenced sources label cooking-oil fires "Class K" (the NFPA term). It is the same hazard — the EN/UAE-correct label is Class F.

Agent-vs-fire-class suitability matrix

EN 3 extinguishers all have a predominantly red body with a colour-coded band identifying the agent: water = red, foam = cream, ABC dry powder = blue, CO² = black, wet chemical = yellow. The matrix below shows where each common agent is suitable (Yes) or unsuitable/hazardous (No).

Agent (colour band)	A solids	B liquids	C gases	D metals	F cooking oil	Live electrical	Key limitation
Water (red)	Yes	No	No	No	No (dangerous)	No (conductive — do not use)	Cheap, effective on A; never on liquids, electrical or cooking oil
Foam / AFFF (cream)	Yes	Yes	No	No	No	No (conductive — do not use)	Good on A and B; not for live electrical or cooking oil
ABC dry powder (blue)	Yes	Yes	Yes	No (needs special Class D powder)	No	Yes (non-conductive)	Most versatile but corrosive residue; discouraged in occupied/enclosed/server spaces
Carbon dioxide / CO² (black)	No	Yes	No	No	No (dangerous)	Yes (non-conductive, no residue)	Clean, ideal for electrical/electronics; poor on solids; never on cooking oil
Wet chemical (yellow)	Yes (most units)	Limited (check rating)	No	No	Yes (only suitable agent)	Generally no — confirm dielectric marking	The required agent for commercial kitchens / Class F
Clean agent (e.g. FK-5-1-12, Halotron)	Yes (larger units)	Yes	Limited	No	No	Yes (non-conductive, residue-free)	Best for sensitive electronics/data; complements ISO 14520 / NFPA 2001 fixed systems

Why these agents behave as they do: CO² is non-conductive and leaves no residue, so it suits live electrical equipment; it works mainly by displacing oxygen. Water and foam are electrically conductive and must not be used on live equipment — note that some EN 3 foam and water-spray units are dielectrically (35 kV) tested and marked safe for inadvertent use up to about 1000 V at 1 m, but they are still not intended as the agent for electrical fires. Wet chemical is the only agent for Class F because it cools the oil and reacts with it by saponification, forming a soapy blanket that smothers the fire and resists re-ignition.

Recommended extinguishers by location

Match the extinguisher to the dominant hazard in each space. The table below is a practical starting point for UAE facilities; confirm quantities, ratings and travel distances against the Code edition in force.

Location	Primary hazards / classes	Recommended portable units	Avoid / cautions
Office / general workplace	Class A (paper, furniture); incidental electrical (PCs)	ABC dry powder or water/foam for Class A, plus CO² for electrical/electronics	Avoid bulk ABC powder right at sensitive electronics; water/foam never on live equipment
Server / IT / electrical switch room	Live electrical equipment; sensitive electronics	CO² and/or clean-agent (FK-5-1-12 / Halotron) portables; back up with a fixed clean-agent system	Never water/foam; avoid ABC powder in occupied rooms (corrosive residue damages hardware)
Commercial kitchen	Class F (cooking oils/fats); some Class A	Wet chemical (Class F) as primary; CO² for nearby electrical cooking equipment	Never water or CO² on a cooking-oil fire; keep the fixed kitchen hood suppression active
Warehouse / workshop	Class A (stored goods); Class B (fuels/solvents); possible Class C gases; electrical	ABC dry powder for broad A/B/C cover; foam where Class B dominates; CO² near machinery	Match to stored commodity; Class D powder only where combustible metals are present
Car park	Class B (fuel/oil); Class A (vehicle interiors); electrical (EVs)	ABC dry powder and/or foam; CO² for electrical	EV / lithium-ion battery fires need special tactics — confirm current Civil Defence requirements

For sensitive-electronics spaces, portable CO² or clean-agent units should complement fixed protection — see our FM-200 and clean-agent suppression and broader fire suppression systems pages, and foam systems for Class B-dominant areas.

The critical DO-NOTs

These four rules prevent the most common and most dangerous extinguisher errors in UAE facilities.

Never use water or foam on live electrical equipment. Both are electrically conductive — there is a real risk of electrocution. Isolate the power first where possible, then use a non-conductive agent (CO² or clean agent).
Never use CO² or water on a cooking-oil (Class F) fire. Water flashes to steam and ejects burning oil; CO² does not cool the oil enough, so it re-ignites and the high-pressure discharge can splash burning oil. Use wet chemical only.
Do not install ABC dry powder as the primary unit in occupied server rooms or sensitive-electronics spaces. The powder is corrosive, leaves a damaging residue on electronics, and reduces visibility. Use CO² or a clean agent instead.
Do not use standard A/B/C agents on combustible-metal (Class D) fires. Many agents react violently with burning metals — only purpose-made Class D agents are safe.

The "versatile ABC powder" message has limits: ABC powder covers A, B and C and is safe on live electrical, but it does not cover Class D metals or Class F cooking oils.

Placement, travel distance and mounting

Even the correct extinguisher is useless if it cannot be reached in time. Follow these qualitative placement rules and confirm the exact metric figures against the applicable Code edition and emirate.

Site extinguishers on exit routes and near the hazards they protect, so a unit is always reachable within a short travel distance.
The UAE Code aligns with NFPA 10, which sets a maximum travel distance of roughly 22.9 m (75 ft) for Class A and about 9–15 m (30–50 ft) for Class B, and around 9 m (30 ft) for kitchen (Class F/K) units — treat these as indicative; the Code may state metric values that differ.
Mount units visibly and unobstructed, with the top within reach. Under NFPA 10, units up to about 18 kg (40 lb) are mounted with the top no higher than roughly 1.5 m, and heavier units lower (top no higher than about 1.07 m) — confirm against the applicable Code.
Keep signage, access and the floor area in front of each unit clear at all times.

Pair extinguisher placement with the rest of your active and passive measures — fire alarm systems, sprinkler systems, fire hose reels and cabinets, emergency exit lighting and passive fire protection — for a coherent life-safety strategy.

Inspection and servicing (qualitative per Code)

The consistent UAE expectation is monthly visual inspection and annual maintenance by a competent, Civil-Defence-approved technician. Extended-service and hydrostatic-test intervals depend on the agent type and on which standard is applied, so the figures below are indicative — confirm which standard your Civil Defence authority requires before fixing any interval.

Monthly: visual inspection — gauge in the green, pin and seal intact, no damage or corrosion, unit accessible and signage clear.
Annually: full maintenance by a certified technician.
Periodically: internal examination and hydrostatic testing at intervals that vary by agent and standard. Under NFPA 10, for example, CO², water and wet-chemical units are hydrostatically tested every 5 years, and stored-pressure dry-chemical units every 12 years (with internal examination at 6 years). BS 5306-3 uses a different extended-service regime.

International UL/FM listings are commonly required but do not replace local approval: extinguishers and agents must appear on the relevant emirate's Civil Defence approved-equipment list before installation. We handle supply, servicing, refilling and Civil Defence approvals, and can cover your portfolio under a fire maintenance AMC. We work across Dubai, Abu Dhabi, Sharjah and Ajman.

A note on clean agents and the environment

For fixed special-hazard protection (data centres, control rooms, archives), clean agents follow ISO 14520 and NFPA 2001. Agent selection is increasingly driven by the Kigali Amendment to the Montreal Protocol, which phases down (does not outright ban) high global-warming-potential (GWP) HFCs. HFC-227ea (FM-200) has a GWP of roughly 3,220, whereas FK-5-1-12 (Novec 1230) and inert gases (IG-541, IG-55, IG-100) have a GWP of about 1. New installations increasingly favour the low-GWP options, and supply of some legacy agents is tightening (3M, for example, ended Novec 1230 production at the end of 2025), so availability is changing — confirm current options with your supplier. GWP values are approximate and depend on the IPCC dataset used; the Kigali phase-down schedule is time-sensitive — confirm current national obligations. See our fire system installation and fire fighting equipment pages, or read more on the blog.

This guide is general UAE fire-safety guidance based on the EN/BS convention and the UAE Fire and Life Safety Code of Practice. Travel distances, mounting heights, service and hydrostatic-test intervals, GWP figures and EV/lithium-ion tactics are edition-, emirate- and standard-dependent — please confirm exact figures and intervals with the Adiga Fire team and your local Civil Defence authority before acting.

Frequently asked questions

Which extinguisher do I use on an electrical fire?

In the UAE/EN system, an electrical fire is classified by what is actually burning, but the extinguisher must use a non-conductive agent. Use a CO2 or clean-agent unit (or dry powder where appropriate) — they are non-conductive. EN 3 units may carry a dielectric marking (typically safe up to about 1000 V at 1 m) for live-equipment use. Never use water or foam on live electrical equipment, because both are conductive and risk electrocution.

Why is Class C confusing between the UAE and US systems?

Because the same letter means different things. Under the EN/ISO convention used in the UAE, Class C means flammable gases (propane, butane, methane). Under US NFPA 10, Class C means energized electrical equipment, and flammable gases are not given a separate class (they are generally covered under Class B). Always state which convention you are using — mixing them up is a high-risk error.

What do I use on a cooking-oil (kitchen) fire?

A wet chemical (Class F) extinguisher only, ideally backed by a fire blanket and a fixed kitchen hood suppression system. Wet chemical cools the oil and reacts with it by saponification to form a smothering soapy blanket. Never use water or CO2 on a fryer — water ejects burning oil and CO2 fails to cool it, so it re-ignites.

Can I just put ABC dry powder everywhere since it is so versatile?

No. ABC powder covers Classes A, B and C and is safe on live electrical, which makes it versatile, but it does not cover Class D combustible metals or Class F cooking oils, and it is discouraged as the primary unit in occupied server rooms because its corrosive residue damages electronics and reduces visibility. Use CO2 or a clean agent there instead.

How often must extinguishers be inspected and serviced in the UAE?

The consistent UAE expectation is a monthly visual inspection (gauge in the green, pin and seal intact, accessible) and annual maintenance by a competent, Civil-Defence-approved technician. Internal examination and hydrostatic-test intervals depend on the agent and the standard applied (NFPA 10 versus BS 5306-3), so confirm the exact intervals with your Civil Defence authority.

Are international UL/FM listings enough for UAE installation?

No. UL/FM listings are commonly required but do not replace local approval. Extinguishers and agents must appear on the relevant emirate's Civil Defence approved-equipment list before installation. We can handle Civil Defence approvals and confirm the right approved equipment for your site.
