KITCHEN FIRE SUPPRESSION

Commercial Kitchen Fire Suppression Systems

General Overview: Importance Of Kitchen Fire Suppression Systems

Your Kitchen Hood Fire Suppression System should be inspected every six months, according to NFPA 96. This inspection must be completed by a licensed fire protection company. Special hazard suppression systems are organised into five main categories being dry chemical, clean agent, commercial kitchen, foam, and CO2. The service inspection should also include the replacement of the nozzles. We would recommend the inspection be coordinated with your duct cleaning provider to reduce inconvenience to the kitchen staff.

Advantages of Kitchen Suppression Systems

  • Automatic & Rapid Response.
  • The system activates immediately when a fire starts, minimising damage and stopping small incidents from escalating.
  • No need for staff to intervene which significantly reduces the risk of injury.

Targets Fire Efficiently

  • Delivers the suppressing agent directly to high-risk areas such as fryers, extractor canopies and ducts.
  • Some systems can automatically shut off gas or electrical supplies to stop fire spread.

Safety and Liability Benefits

  • Protects both people and property, reducing disruption and financial loss.
  • Often reduces insurance premiums or is required by insurers as part of coverage.
  • Designed to limit downtime and cleanup, for instance, systems like ANSUL R-102 claim cleanup can be done quickly with basic cleaning tools.

Legal and Regulatory Context in the UK
No outright legal mandate, but under the Regulatory Reform (Fire Safety) Order 2005, the “”responsible person”” must conduct a fire risk assessment. If risk is high (common in kitchens), a suppression system is a realistic necessity. Insurers frequently require, or strongly recommend, suppression systems in high-risk kitchens and may invalidate cover if omitted. Fire authorities or building control might necessitate systems based on assessed risks, especially for open-plan or diner-facing kitchens.

Key Standards to Know

  • BAFE SP206 Scheme – Covers design, installation, commissioning, maintenance, and recharge of kitchen suppression systems by certified providers. Systems should align with LPS 1223 (commercial fixed suppression standards) and UL 300 (North American standard).
  • LPS 1223 Requirements – Testing includes fire detection, activation, extinguishing, plus maintenance and service documentation. Must protect both cooking appliances and exhaust hoods, support manual and automatic activation, ensure fuel/equipment shut-off, and integrate with fire alarm systems. Prevent user from isolating suppression power without also cutting off cooking equipment’s fuel/electric supply.
  • BS EN 17446:2021 – Applies to domestic/residential kitchen systems, emphasizing safe operation and manual activation.
  • Maintenance & Competence – Systems must be serviced every six months by BAFE SP206 certified engineers, who issue a Certificate of Conformance after each visit. Upon discharge (triggered or incidental), systems must be professionally recharged to restore readiness.

What You Should Do Next

  • Commission a Fire Risk Assessment – If it shows high risk, a suppression system is likely needed.
  • Specify BAFE SP206 Certification – Demand design, install, and maintenance by certified practitioners.
  • Ensure Compliance with LPS 1223 – Confirms system performance and safety.
  • Schedule Maintenance – Every six months by qualified professionals.
  • Coordinate with Insurers and Authorities – Make sure your system meets their specific requirements

Fire Warden Training

Fire Warden training is the cornerstone of any fire safety strategy, the actions of informed and well trained Fire Wardens have been proved to save lives and reduce the risk to commercial property. Their role in dealing effectively with an evacuation from a fire, in ensuring that the area is empty of people not involved in fighting a fire, will not only help save lives but assist the fire fighters in acting quickly. This will give staff a greater awareness of the hazards a fire will present, and increase their knowledge of practical fire safety measures.

Frequently Asked Questions About Commercial Kitchen Fire Suppression

A kitchen fire suppression system provides fixed fire protection for commercial cooking equipment and associated extraction areas. It helps control or extinguish fires involving cooking oils, fats and other hazards within its designed coverage.

Many systems use automatic heat detection to activate the suppression equipment. They release a suitable extinguishing agent through strategically positioned nozzles to protect specified cooking appliances and, where required, associated extraction components.

The system designer determines the correct coverage, activation arrangements and extinguishing agent according to the kitchen’s equipment and fire risks.

A commercial kitchen fire suppression system detects a fire and releases an extinguishing agent onto the protected cooking equipment and associated areas.

Many systems use heat-sensitive detection components, such as fusible links or other approved detection arrangements. When the system activates, it releases the agent through a network of pipes and nozzles.

Depending on the design, activation may also trigger cooking fuel or electrical shut-off arrangements and send a signal to the building’s fire alarm system.

Kitchen staff must still raise the alarm, follow emergency procedures and evacuate when necessary. Automatic suppression does not replace these responsibilities.

Restaurants, hotels, takeaways, pubs, commercial catering facilities and other professional kitchens may benefit from fixed fire suppression systems.

Kitchens that use deep-fat fryers, grills, ranges, woks or other high-temperature cooking equipment can present significant fire risks, particularly where cooking oils and grease accumulate.

A suitable fire risk assessment, the building’s fire safety strategy and any relevant insurer requirements should help determine whether the kitchen needs a suppression system.

Not every commercial kitchen has an identical requirement. The decision depends on the cooking processes, equipment, premises and applicable requirements.

UK legislation does not impose a universal requirement for every commercial kitchen to install a fixed fire suppression system.

In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 requires the Responsible Person to assess and manage fire risks and provide appropriate fire safety measures. Scotland and Northern Ireland have separate fire safety legislation.

A fire risk assessment, building design requirements or insurance conditions may identify the need for a suitable kitchen suppression system.

Businesses should obtain competent fire safety advice rather than assume that every kitchen has the same legal or technical requirements.

Wet chemical and water mist systems use different methods to help control kitchen fires.

Wet chemical systems release a specially formulated agent that helps cool burning cooking oils and fats. The agent can also form a protective layer over the surface to help reduce the risk of re-ignition.

Water mist systems use fine water droplets to cool and suppress fires. However, the system must have suitable test evidence and approval for the specific cooking hazards and equipment it protects.

Neither method suits every application automatically. A competent designer should select a system with appropriate tested performance for the kitchen.

Commercial kitchen fire suppression systems need regular inspection, testing and maintenance to help ensure they remain ready to operate.

Many manufacturers and system approvals specify specialist servicing at six-month intervals. The appropriate schedule depends on the installed system, manufacturer instructions, applicable standards and any insurer requirements.

Kitchen managers should also arrange suitable routine visual checks and report damaged components, blocked nozzles, warning indicators or changes to protected cooking equipment.

A competent service provider should confirm the maintenance requirements for the particular installation.

Yes. Many commercial kitchen suppression systems can activate suitable fuel or electrical isolation arrangements when the system operates.

These interfaces help reduce the risk of continued heating after suppression begins. Depending on the kitchen’s design, the system may also interact with fire alarms, ventilation equipment and other safety controls.

The designer must establish the correct shutdown and ventilation sequence for the installed equipment and relevant standards.

Do not assume that every system automatically isolates all appliances or shuts down every ventilation fan. The required operation depends on the approved design.

After activation, kitchen staff should follow the emergency plan, keep people away from the affected area and contact the appropriate emergency services where necessary.

Do not restart the cooking equipment or attempt to reset the suppression system before a competent specialist has assessed the installation.

The service provider may need to inspect the protected equipment, replace or recharge the extinguishing agent, restore activation components and complete relevant testing.

Staff should only resume cooking once the appropriate specialists have confirmed that the equipment and fire protection arrangements are safe and ready for use.

Regular checks can help kitchen managers identify potential problems before they affect the suppression system’s performance.

Warning signs include:

  • Blocked nozzles – Grease, dirt or cooking equipment obstructing the discharge points.
  • Damaged components – Visible damage to pipes, nozzles, detection equipment or manual activation devices.
  • Warning indicators – Fault signals or abnormal pressure readings where the system provides them.
  • Equipment changes – New or relocated appliances that may no longer match the original nozzle coverage.
  • Overdue servicing – Missing maintenance records or a service date that has passed.
  • Previous activation – A system that has discharged or partially operated and needs specialist attention.

Report any concerns promptly and ask a competent suppression specialist to assess the system. Kitchen staff should not attempt unauthorised repairs or adjustments.

Advice When Choosing and Maintaining Commercial Kitchen Fire Suppression Systems

Before selecting a kitchen fire suppression system, review your fire risk assessment and identify the hazards associated with your cooking equipment and working practices.

Consider the types of appliances, cooking temperatures, oils and fats, extraction arrangements and the potential for fire to spread beyond the immediate cooking area.

A competent fire safety professional can help establish whether your kitchen needs fixed suppression and how it should fit into the building’s wider fire safety strategy.

Different cooking appliances present different fire risks. Choose a suppression system that provides suitable protection for the equipment your kitchen uses.

Important considerations include:

  • Deep-fat fryers – Assess the risk of high-temperature cooking oil fires and re-ignition.
  • Grills and griddles – Consider grease accumulation and the potential for flames to spread.
  • Wok ranges – Review the operating temperatures, cooking methods and equipment configuration.
  • Ranges and hobs – Check the cooking hazards and the system’s approved appliance coverage.
  • Extraction canopies – Assess whether the hood, plenum and ductwork require protection.
  • Future equipment changes – Consider whether planned kitchen alterations could affect the original suppression design.

Ask the system designer to confirm that the proposed equipment and nozzle arrangements match the system’s tested and approved applications.

Choose a kitchen fire suppression system with appropriate evidence of testing, approval and suitability for your commercial cooking risks.

BS EN 17446:2021+A1:2024 covers the design, documentation and testing of fixed fire extinguishing systems for commercial kitchens. Other standards and approval schemes may also apply, depending on the product and installation.

Ask your provider to explain which standards, product approvals and manufacturer requirements apply to the proposed system.

Where relevant, check the provider’s competence and registration under an appropriate scheme, such as BAFE SP206. Do not assume that a company’s general fire safety accreditation covers every specialist suppression activity.

A kitchen suppression system should operate alongside the appropriate emergency controls and procedures.

Discuss the following with your system designer:

  • Automatic activation – How the system detects a fire and releases its extinguishing agent.
  • Manual activation – Where staff can safely operate the manual release device.
  • Fuel isolation – Which gas or other fuel supplies need to shut off when the system activates.
  • Electrical isolation – Whether the design requires specific cooking equipment or circuits to disconnect.
  • Fire alarm integration – How the suppression system communicates with the building’s alarm arrangements.
  • Ventilation controls – How the extraction and supply-air systems should respond during activation.

The required sequence depends on the system approval, applicable standards and kitchen design. A competent specialist should confirm these arrangements during commissioning.

Grease accumulation in extraction systems can increase the risk of fire spreading beyond the cooking equipment.

Arrange suitable cleaning of extraction canopies, filters, plenums and ductwork according to the kitchen’s usage and assessed risks.

Coordinate cleaning activities with the suppression maintenance provider where practical. Cleaning contractors must avoid damaging nozzles, detection components and other suppression equipment.

Remember that a kitchen fire suppression system does not replace regular extraction cleaning, safe cooking practices or appropriate fire prevention measures.

Regular maintenance helps keep your kitchen fire suppression system ready to operate when needed.

Your maintenance arrangements should include:

  • Routine visual checks – Look for obvious damage, obstructions and changes around protected equipment.
  • Nozzle inspection – Check that discharge points remain correctly positioned and unobstructed.
  • Detection equipment – Arrange suitable checks of the system’s approved detection components.
  • Controls and interfaces – Test relevant activation, isolation and alarm functions as required.
  • Extinguishing agent – Check the condition and quantity of the agent according to manufacturer instructions.
  • Service records – Keep inspection reports, maintenance documents and details of corrective work.

Many kitchen suppression systems require specialist servicing every six months under their manufacturer instructions or approval conditions. Ask your maintenance provider to confirm the correct interval for your installation.

Kitchen staff should understand how the suppression system works and what actions to take if a fire occurs.

Training should cover:

  • How to recognise and raise the fire alarm.
  • The location and purpose of the suppression system’s manual activation device.
  • When and how authorised staff should activate the system manually.
  • The importance of keeping a safe distance from a fire.
  • How to evacuate using the designated escape routes.
  • Why staff must not restart cooking equipment after a suppression discharge.
  • How to report faults, damage or changes to protected appliances.

Remind employees that personal safety comes first. Staff should never put themselves at risk by attempting to control a fire.

Choose a provider with relevant experience in commercial kitchen fire suppression systems and the equipment installed at your premises.

Ask about system approvals, specialist competence, installation arrangements, maintenance requirements and the support available after activation.

Your provider should explain how the proposed system protects your cooking equipment, how it interacts with other safety systems and what documentation you will receive.

SS Systems provides commercial kitchen fire suppression services alongside wider fire protection solutions. Contact the team to discuss your premises and the protection your kitchen may require.

Bonus Tip: Whenever you replace, relocate or add cooking appliances, ask your suppression provider to review the existing system before using the new layout. Even a small equipment change can affect nozzle positioning, detection arrangements and the protection your kitchen needs.
