Kitchen Extraction Fire Risk: How TR19® Grease Fits into Fire Safety Management
TR19® Grease can support management of grease-related fire risk. It does not replace the premises fire-risk assessment.
Commercial cooking can deposit grease within canopies, ductwork, fans and other parts of a kitchen-extract system. That accumulation can become part of the building’s fire-risk picture. The responsible organisation needs to connect any extract-cleaning action with the wider fire-safety management process rather than treating a cleaning certificate as a substitute for the fire-risk assessment.
Kitchen-extract maintenance is one control within a much larger fire-safety system.
Fire safety for commercial premises includes far more than the kitchen. The responsible organisation may need to consider ignition sources, combustible materials, fire detection, alarm systems, compartmentation, escape routes, firefighting equipment, emergency arrangements, vulnerable occupants, staff training and the way the premises are managed.
Government guidance for England says the Responsible Person must carry out and regularly review a fire-risk assessment, identify hazards and people at risk, remove or reduce risks, record findings and maintain appropriate fire-safety measures. Wales operates the same Fire Safety Order framework with its own government guidance. Scotland and Northern Ireland have separate non-domestic fire-safety legislation.
A specialist specification for managing grease accumulation within kitchen extraction.
BESA describes TR19® Grease as the definitive specification for managing the fire risks associated with grease accumulation in commercial kitchen extraction systems. It defines industry best practice for inspection, cleaning and fire-risk management of kitchen-extract ventilation.
BESA’s current TR19 toolkit also explains that commercial kitchen extract systems can be a source or contributory factor in fires and that concern about grease deposits has driven expectations from insurers, property owners and landlords for correct cleaning and maintenance.
That makes TR19® Grease highly relevant where a fire-risk assessment or other professional recommendation identifies kitchen-extract grease as an issue. It remains a technical specification rather than the legislation itself.
The fire-risk assessor considers the premises as a whole. The kitchen-extract specialist addresses the technical work within the scope for which they have been appointed.
Preserve the assessor’s recommendation instead of rewriting it as a generic cleaning order.
A fire-risk action may say that the kitchen extraction requires cleaning, that evidence is missing, that the frequency should be reviewed, that an inaccessible section needs attention or that a particular system condition needs specialist investigation.
The safest procurement approach is to keep the original wording attached to the contractor enquiry. The facilities team can provide the system information, previous reports and photographs without turning the assessor’s professional conclusion into a new conclusion of its own.
After physical work is completed, the resulting report can be returned to the fire-risk assessor or other originating professional if they need to review whether their recommendation has been adequately addressed.
Grease can accumulate where the kitchen team cannot see it.
Canopy, filters & plenum
These are the most visible parts of the extract system and often receive routine attention, but they are only the beginning of the airflow route.
Horizontal ductwork
Grease deposits can accumulate internally above ceilings or within service zones where the condition is not visible from the kitchen.
Vertical risers & concealed routes
Long or enclosed duct runs can create significant access challenges. If the route cannot be reached, the uncertainty should remain explicit in the maintenance record.
Fan & discharge
The downstream fan and discharge arrangement form part of the extract route and may require roof, plant-room or landlord-controlled access.
An inaccessible section can be a fire-risk management issue, not just a cleaning inconvenience.
If the contractor cannot inspect or clean part of a grease extract system, the condition of that section may remain unknown. The response should therefore separate the completed clean from the unresolved access problem.
The next action might involve additional duct access, safe high-level access, landlord permission, roof access or another competent trade. The technical solution depends on the actual building and system.
If it affects a fire-risk recommendation, the exclusion should remain open until the responsible organisation and appropriate professionals decide how it will be resolved.
Fire-risk management needs visibility beyond the kitchen-facing surfaces.
The historic EC Cleaners archive contains commercial kitchen and high-level grease-cleaning images from different premises. They illustrate why grease-management evidence should follow the relevant extraction route rather than concentrate only on the canopy that is easiest to photograph.
These are historic project images only. They are not current Search and Submit Ltd fire-risk assessments and do not represent a retrospective fire-safety judgement on the original premises.
Using a specialist contractor does not hand the building’s fire-safety duty to the cleaner.
For England, current government guidance says employers, owners, landlords, occupiers and others with control of non-domestic premises can be Responsible Persons. It expressly gives facilities managers, building managers and managing agents as examples. Where there is more than one Responsible Person, they must work together.
In Wales, the Fire Safety Order framework likewise places responsibilities on the Responsible Person and requires the fire-risk assessment and fire-safety arrangements to be recorded. Scottish non-domestic fire safety is principally governed by the Fire (Scotland) Act 2005 and Fire Safety (Scotland) Regulations 2006. Northern Ireland operates under the Fire and Rescue Services (Northern Ireland) Order 2006 and Fire Safety Regulations (Northern Ireland) 2010.
The precise legal structure therefore varies by UK nation, but the commercial principle is consistent: appoint the right specialist for kitchen-extract work while keeping the wider premises fire-safety responsibilities with the appropriate dutyholders.
A cleaning certificate is evidence of an event—not automatic proof that the fire-risk action is closed.
The responsible organisation should compare the contractor’s returned information with the original fire-risk recommendation. Did the contractor address the intended system? Were the relevant sections accessible? Are photographs and other expected records present? Did the contractor identify further technical or access issues?
If the fire-risk assessor needs to review the evidence, send the complete record back to them rather than asking the cleaning contractor or EC to make the assessor’s conclusion.
Do not turn a generic interval into a substitute for risk-based maintenance.
Kitchen-extract cleaning frequency can be influenced by cooking type, hours of use, grease loading, system condition, measurement, previous reports, insurer requirements and competent technical assessment. A busy high-volume frying operation may require a different maintenance regime from a lightly used commercial kitchen.
The fire-risk assessment can identify that grease accumulation needs control, while the kitchen-extract specialist can assess the system within their technical scope. Where an insurer or other professional has imposed a specific requirement, that wording should also remain part of the maintenance plan.
EC should not invent a universal cleaning frequency and present it as legislation. The purpose of this guidance is to keep the fire-risk trigger, technical assessment and contractor evidence connected.
EC coordinates physical close-out; it does not become the fire-risk assessor.
EC Cleaners Network can take a customer-supplied fire-risk action, help identify the relevant kitchen-extract system information, organise previous reports and access exclusions, structure a commercial contractor enquiry and return the resulting documentation for review.
EC does not carry out fire-risk assessments, determine whether a premises is compliant with fire-safety law, decide whether a fire-risk action can be closed, prescribe fire-engineering measures or certify a kitchen-extract system as safe.
Where a fire-risk assessor made the original recommendation, EC’s preferred approach is simple: your recommendation remains yours. The specialist contractor delivers the agreed physical work, and the resulting evidence can return to the adviser for whatever professional review sits within their appointment.
Send the exact recommendation and the latest extract report together.
Include the fire-risk action, system location, previous cleaning report, photographs and any known access problem. EC can help organise a clearer commercial requirement for independent specialist delivery while leaving the fire-safety conclusion with the appropriate competent professional.
