Restaurant fire safety starts in the kitchen, but it does not end there. A restaurant or café puts a constant heat source, cooking oil, gas and dense electrical wiring in one small space, next to a dining room full of guests who do not know the building or its exits.
This guide walks through a restaurant zone by zone: the kitchen, the dining area, the store and back-of-house, the electrical panels and the exits. For each zone it explains what is checked under the Saudi framework and where each system’s role starts and stops. The systems and services AZEIDK provides for the sector are on our hospitality and restaurants page.
Key takeaways
- The commercial kitchen is the highest-risk point. It is protected by a listed automatic hood suppression system, with a Class K extinguisher as backup.
- Sprinkler and alarm requirements for the dining area depend on fire area, occupant load and the restaurant’s floor level. Do not copy them from another restaurant.
- The store, the electrical panel and the exit routes generate many inspection findings, and they are usually cheaper to fix than the kitchen.
- The safety licence is issued through the Civil Defense «Salamah» platform. The activity and its risk category set the licensing route.
- Changing the menu, the cooking equipment or the floor area can change the protection requirements. Review the system before the change, not after.

Why restaurant fire safety differs from other shops
A normal shop stores goods and receives customers. A restaurant adds a daily heat process: frying, grilling and cooking on gas or electric equipment, with grease vapour settling inside the hood and the exhaust duct. A fire can start where staff cannot see it, inside the duct, and spread fast.
The dining area adds a second factor: many guests at once, sometimes low lighting, and combustible furniture and décor. Under the International Building Code (IBC) model, which the Saudi Building Code follows for occupancy classification, restaurants become Group A-2 assembly occupancies once their occupant load reaches a set threshold. Very small restaurants are treated differently.
The legal reference in Saudi Arabia is the Saudi Building Code, led by the Saudi Fire Protection Code (SBC 801), together with the requirements of the General Directorate of Civil Defense. NFPA standards such as NFPA 96 (commercial cooking ventilation), NFPA 17A (wet chemical systems) and NFPA 10 (portable extinguishers) are technical references that the designer adopts or the project documents call for.
The kitchen: the main hazard
NFPA 96 requires the primary protection for cooking equipment that produces grease-laden vapours to be an automatic suppression system, with portable extinguishers as backup, not as a substitute. Automatic systems are required to be listed to UL 300 or equivalent, because modern frying oils need a wet chemical agent that cools the oil and forms a barrier layer on its surface.
What to check on the hood system
- Coverage of every appliance under the hood, the filters and the duct itself, per the system’s listed design manual.
- Automatic gas shut-off to the appliances when the system discharges, and power shut-off to electric appliances, with manual reset.
- A manual pull station on the egress path out of the kitchen, easy to reach and not blocked by shelving.
- A discharge signal to the building fire alarm panel where one exists.
The kitchen systems AZEIDK supplies in Saudi Arabia include ANSUL R-102 and Hood Safer, alongside American Fire Control and Falcon Gold systems. System details and components are in our commercial kitchen suppression guide, so we do not repeat them here.
The Class K extinguisher
NFPA 10 calls for a Class K extinguisher for hazards involving cooking oils and fats, within a travel distance of 9.1 m (30 ft). Where an automatic system is installed, a placard reminds staff to activate the system first and then use the extinguisher. A dry powder extinguisher is not a substitute on burning oil.
Hood and duct
A clean duct is part of the protection. Built-up grease is ready fuel, and NFPA 96 sets inspection frequency by cooking volume and fuel type. Cleaning the visible filters is not enough if the duct behind them is coated in grease.
The dining area
In the dining room the question changes from “how do we put out an oil fire?” to “how do guests learn about the fire and get out safely?”. The answer depends on floor area, occupant load and location.
Sprinklers
IBC Section 903.2.1.2, as summarised by MeyerFire, requires an automatic sprinkler system for A-2 occupancies when any one of these core conditions applies: the fire area exceeds 5,000 sq ft (about 465 m²), the fire area has an occupant load of 100 or more, or the fire area is on a floor other than the level of exit discharge. The binding text is the matching clause in the SBC 801 edition in force, so check it before the design is approved. Most restaurants in malls sit in sprinklered buildings already, so the real question is adjusting the layout after fit-out.
Alarm and evacuation
The dining area needs manual call points (MCPs) at the exits and audible and visual notification that can be heard and seen over the noise of the room. In a restaurant inside an existing building, the system ties into the building panel instead of a separate panel installed without coordination. Coordinate this link with the kitchen system described on AZEIDK’s kitchen fire suppression solutions page.
Décor and furniture
Suspended ceilings, timber walls and fabrics are part of a café’s identity, but they can obstruct sprinklers or change the ceiling height the layout was designed for. Review any new décor against the fire drawings before work starts.
Store, back-of-house and electrical
- Dry store: cartons, bags and stored oil, kept clear of sprinklers and panels and never stored in exit corridors.
- Gas cylinders: stored and connected per the authority’s requirements, with the main shut-off valve checked for easy access.
- Electrical panel: closed and labelled, with clear space in front, and no temporary wiring or daisy-chained power strips for heavy equipment.
- Fridges and cold rooms: compressors give off heat and need ventilation and regular cleaning.
None of these needs a complex system, but they keep appearing in inspection findings because daily operation changes them.
Exits and emergency lighting
The number and width of exits are fixed by the design occupant load. What changes after opening is their condition: extra tables narrowing the aisle, a back door locked against theft, an exit sign that is out. Emergency lighting and exit signs must work on power failure and be tested regularly. See our emergency lighting and exit signs guide.
Quick review table by zone

Licensing through Salamah and renewal
A restaurant or café obtains its safety licence through the «Salamah» platform of the General Directorate of Civil Defense, linked to the commercial licence on the «Balady» platform. The activity type and its risk category decide the route: some activities are licensed by entering a safety equipment invoice or a technical report, while others need a maintenance contract with a qualified company and an inspection before issue. Details are in our article on safety requirements for shops through Salamah and Balady.
It does not stop at opening day. Adding a fryer or oven, extending the dining area, or turning a café into a full-cooking restaurant can change the risk category and the protection required. Periodic inspection of the kitchen system is recorded in a log shown at inspection or renewal; the scope is covered in our article on kitchen suppression inspection and maintenance.
Common mistakes in restaurants and cafés
- Moving an appliance or adding a new one under the hood without adjusting the suppression nozzles.
- Relying on a dry powder extinguisher in the kitchen instead of a Class K unit.
- A pull station behind a door or shelving, or away from the route staff take to leave.
- A new ceiling feature that blocks sprinklers or changes the ceiling height.
- Cartons stored in the back corridor leading to the emergency exit.
- Staff not trained in the response sequence: activate the system, raise the alarm, evacuate.
Frequently asked questions
Does a café that does not fry need a hood suppression system?
It depends on the cooking equipment and the vapours it produces. A café using heating equipment that produces no grease-laden vapour differs from one serving fried or grilled food. This is decided at design stage with the authority.
Are the building sprinklers enough for a restaurant kitchen in a mall?
Standard sprinklers do not replace a listed hood system. Both are used per the design, with the kitchen system’s signal connected to the building fire alarm panel.
Where does the Class K extinguisher go?
Within 9.1 m travel distance of the cooking equipment per NFPA 10, in a visible spot near the exit route, with a placard reminding staff to activate the automatic system first.
Does the safety licence change if we extend the dining area?
It can. More floor area or seats can change the risk category and the licensing route on Salamah, and can add sprinkler or alarm requirements.
How often is the kitchen system inspected?
Usually every six months per NFPA 17A and the manufacturer’s instructions, with simple monthly checks by the operator.
Conclusion
A safe restaurant has a kitchen protected by a listed system, a dining area where fire is detected early and guests can leave without obstruction, and an orderly back-of-house. Most problems do not come from the design but from daily changes after opening. Reviewing each change before it is made costs less than clearing an inspection finding.
