--- title: restaurant, the responsible person—usually the owner, manager, or landlord require you to manage health and safety risks to employees and others affected by your work.

To demonstrate compliance:** Deep clean every 12 months.

These timeframes align with industry guidance such as the TR19® Grease standard for kitchen extraction systems. You should maintain a cleaning logbook on-site as evidence for fire safety inspectors and your insurance provider.

Fixed Fire Suppression Systems

Given the high risk of deep-fat fryer fires, many commercial kitchens require fixed fire suppression systems. These systems are designed to detect heat and discharge a wet chemical agent that cools the burning oil and forms a blanket to prevent re-ignition.

If your kitchen operates deep-fat fryers or high-output cooking equipment, a fixed suppression system is strongly recommended. These systems must be installed and maintained according to the relevant British Standards by competent engineers. Routine servicing—typically every six months—ensures the system remains functional and compliant.

It is important to note that standard fire extinguishers are not a substitute for a fixed suppression system. However, portable equipment remains a necessary backup.

Fire Extinguishers and Detection

Providing the right fire extinguishers is a legal requirement under the RRO. In a commercial kitchen, you must provide:

Class F wet chemical extinguishers: Essential for deep-fat fryer fires. Using the wrong extinguisher on a cooking oil fire can cause violent splashing and spread the fire.
CO2 extinguishers: Suitable for electrical fires involving appliances.
Fire blankets: Useful for smothering small pan fires or wrapping around a person whose clothing has ignited.

Detection systems must also be tailored to the kitchen environment. Standard smoke detectors are unsuitable for commercial kitchens because normal cooking operations will cause false alarms. Instead, heat detectors should be installed in the kitchen area, while smoke detectors should be placed in dining areas, corridors, and storage rooms. All detection and warning systems must be maintained in good working order.

Staff Training and Emergency Planning

Even the best equipment is ineffective if staff do not know how to respond. Under the RRO, you must provide adequate fire safety training for all employees. This training should cover:

1. Identifying fire hazards in the kitchen. 2. Safe use of cooking equipment and isolation procedures. 3. Correct selection and use of fire extinguishers and blankets. 4. evacuations-evacuation routes and assembly points. 5. Reporting faults or damaged equipment.

Training must be repeated periodically and documented. New staff should receive induction training before working their first shift. Your emergency plan must also account for the safe evacuation of customers, including those with disabilities.
