Kitchen extraction cleaning - food courts
A shopping centre food court concentrates many food outlets in one space, frequently sharing extraction infrastructure - so keeping the ductwork compliant is a challenge at scale: many kitchens, shared systems, and multiple parties who all have to coordinate. Here is how extraction compliance works across a food court, and why coordination matters. This is general information, not legal advice.
The short answer
A shopping centre food court is a distinctive extraction challenge: many kitchens packed into one space, usually sharing extraction infrastructure, all needing to stay compliant together. It's not one kitchen's problem but a shared, at-scale one - and it only works with coordination. Here's how food-court extraction compliance works. This is general information, not legal advice; the leases and arrangements govern the specifics. Many kitchens, often shared systems. A food court concentrates many food outlets - often a dozen or more, doing all kinds of cooking (grilling, frying, wok, and more) - into one space. And they frequently share extraction infrastructure: a common or shared ductwork and extraction system serving multiple units, or a set of systems within one shared building structure, rather than each unit having a wholly independent, separate system. So the extraction is a shared, concentrated setup - which shapes everything about keeping it compliant. Why compliance is a challenge at scale. Several things make food-court extraction compliance harder than a single kitchen's: Scale and grease loading. Many kitchens cooking heavily in one place generate a large volume of grease, so a shared extraction system loads fast and heavily - meaning a high cleaning frequency is needed, and the fire risk is concentrated. Shared responsibility. On a shared or common system, no single tenant controls the whole thing - so the cleaning can't be left to each unit in isolation (each cleaning only its own bit, with the shared parts falling between them). Responsibility for the shared system has to be established and coordinated. Fire safety at scale. A duct fire in a shared food-court system threatens not just one unit but many units and potentially the whole centre - and fire safety in a multi-occupancy building is a shared, serious matter (with the centre and tenants having overlapping duties). So the stakes are high and collective. Multiple parties. The individual tenants/operators and the centre landlord/management all have a role - so compliance depends on them working together. How it's managed: coordination. The answer to all this is coordination at scale, typically organised centrally. In practice, food-court extraction compliance is usually managed by the centre management coordinating the cleaning of the shared extraction system - arranging for the common ductwork and extraction to be cleaned to the TR19 Grease standard at an adequate (high) frequency, across the units, with responsibilities defined (who cleans what - the shared parts and the unit parts) and the cleaning evidenced (certificates for the shared system and the units). The tenants keep their own parts (canopies, filters, their ductwork) cleaned and coordinate with the centre's arrangements. So rather than each unit acting alone, the compliance is organised across the food court - the shared system cleaned centrally and coordinated, the units cleaned and coordinated in. This is the practical way to keep a concentrated, shared, high-loading system compliant. The takeaway. So a shopping centre food court makes extraction compliance a shared, at-scale challenge - many kitchens, shared systems, high grease loading, concentrated fire risk, multiple parties - and it's kept compliant by coordination: the shared extraction cleaned to standard at an adequate frequency, organised across the tenants and centre management, with clear responsibilities and evidence. It's ordinary extraction compliance, but shared and coordinated at scale. So coordinate the cleaning of the shared system across the parties, at an adequate frequency, with clear responsibility and proof. This is general information, not legal advice; the leases and arrangements govern the specifics.
Key points
Many kitchens, shared systems
A shopping centre food court is a distinctive setup: many food outlets - often a dozen or more, doing all kinds of cooking - concentrated into one space, and frequently sharing extraction infrastructure. Rather than each unit having a wholly independent, separate extraction system, food courts commonly have a common or shared ductwork and extraction system serving multiple units, or a set of systems within one shared building structure. So the extraction is concentrated (many kitchens in one place) and often connected (units sharing a system).
This concentrated, connected nature is what makes food-court extraction compliance different from a single kitchen's. It's not one kitchen to keep compliant, but many - often on a shared or interconnected system, with the grease of all those kitchens loading it, and with multiple parties (the tenants and the centre management) involved. So the whole compliance picture is shared and at scale. Understanding this setup - many kitchens, shared systems - is the key to why coordination is essential (a shared system can't be kept compliant by units acting alone) and why the loading and fire risk are concentrated. The following sections cover those challenges and how coordination addresses them. So a food court is a concentrated, connected extraction setup - which shapes how it's kept compliant. So many kitchens on shared systems change the compliance challenge. This is general information, not legal advice.
Scale and grease loading
The first at-scale challenge is the sheer grease loading. A food court has many kitchens cooking heavily in one place - grilling, frying, wok cooking and more, all day - so together they generate a large volume of grease. On a shared extraction system, all that grease loads the common ductwork fast and heavily. So the system accumulates grease far quicker than a single kitchen's would, and the fire risk is concentrated in the shared ductwork.
This has a direct compliance implication: the cleaning frequency needs to be high, matched to the heavy, concentrated loading (a risk-based frequency for a heavily-loaded shared system is frequent). Under-cleaning such a system lets a lot of grease build up in a shared duct serving many units - a serious, concentrated fire risk. So the scale means both more grease to manage and a greater consequence if it's neglected. This is why food-court extraction can't be treated casually - the loading is high and the risk concentrated. So scale and grease loading - a lot of cooking, a lot of grease - is the first reason food-court compliance is demanding: the shared system loads fast and must be cleaned often to keep the concentrated fire risk controlled. So expect a high cleaning frequency for the heavily-loaded shared system. So the heavy loading demands frequent cleaning. This is general information, not legal advice.
Shared responsibility
The second at-scale challenge is shared responsibility. On a shared or common extraction system, no single tenant controls the whole thing - the shared ductwork and extraction serve multiple units, so they're not any one unit's sole domain. This means the cleaning can't be left to each unit acting in isolation: if each tenant cleans only its own part (its canopy, filters and immediate ductwork) and assumes the shared system is someone else's job, the shared parts can fall between everyone - uncleaned, with grease building in the common duct.
So responsibility for the shared system has to be established and coordinated - not left to chance or assumption. This is a version of the multi-tenant shared-duct responsibility issue (covered in the multi-tenant shared duct responsibility and TR19 Grease compliance for multi-tenant buildings pages), concentrated in a food court: who is responsible for cleaning the shared extraction (typically the centre management, via the leases and service arrangements), and how the units' parts and the shared parts fit together, must be clear. Otherwise the shared system - the highest-loading, highest-risk part - is exactly what gets neglected. So shared responsibility - no one unit controls the whole system - is why coordination is essential: the shared parts need a clear, coordinated owner and cleaning arrangement, not a gap between tenants. So establish who cleans the shared system, clearly. This is general information, not legal advice; the leases govern.
Fire safety at scale
The third at-scale challenge is that fire safety in a food court is a shared, high-stakes matter. A duct fire in a shared food-court extraction system doesn't threaten just one unit - it threatens many units connected to the system, and potentially the whole shopping centre (a busy, populated building). So the consequence of neglect is collective and severe: a concentrated grease fire in a shared duct in a large public building. And fire safety in a multi-occupancy building like a shopping centre is a shared responsibility, with the centre and the tenants having overlapping fire-safety duties.
So the fire-safety stakes raise the importance of getting food-court extraction compliance right: it's not one operator's risk to carry or neglect, but a shared risk to many units and the centre, in a building full of people. This is why food courts (and their centre management) typically take extraction compliance seriously and organise it properly - the risk is too big and too shared to leave to chance. It's also why the coordination (covered next) matters so much: the shared fire risk needs a coordinated, reliable cleaning regime, not a patchy one. So fire safety at scale - a shared risk to the whole centre - is what makes food-court extraction compliance a serious, collective priority. So the shared, high fire risk demands a properly-organised cleaning regime. So the concentrated fire risk makes coordination essential. This is general information, not legal advice.
Managed by coordination
The answer to all these at-scale challenges is coordination - typically organised centrally by the centre management. In practice, food-court extraction compliance is usually managed by the centre coordinating the cleaning of the shared extraction system: arranging for the common ductwork and extraction to be cleaned to the TR19 Grease standard at an adequate (high) frequency, across the units, with responsibilities defined (who cleans the shared parts and who cleans the unit parts - canopies, filters, unit ductwork) and the cleaning evidenced (certificates for the shared system and each unit). The tenants keep their own parts cleaned and coordinate with the centre's arrangements.
So rather than each unit acting alone (with the shared system falling between them), the compliance is organised across the food court: the shared system cleaned centrally and coordinated, the units cleaned and coordinated in, the whole thing at an adequate frequency for the heavy loading, with clear responsibilities and evidence. This coordinated approach is what keeps a concentrated, shared, high-loading system genuinely compliant and its fire risk controlled. So managed by coordination - organise the cleaning across the parties - is how food-court extraction compliance works: the centre management and tenants working together to keep the shared and unit systems cleaned to standard. If you operate in or manage a food court, the key is to be part of that coordinated regime (clear on your responsibilities, cleaning your parts, and evidencing it) rather than acting in isolation. So coordinate the cleaning of the shared and unit systems across the parties. This is general information, not legal advice; the leases and arrangements govern the specifics.
Questions
Because a food court packs many heavily-cooking kitchens into one space, often on shared ductwork - so the grease loading is high and concentrated, responsibility is shared, the fire risk threatens the whole centre, and multiple parties must coordinate. A shopping centre food court concentrates many food outlets (often a dozen or more, cooking heavily) into one space, frequently sharing extraction infrastructure. This makes compliance harder than a single kitchen's for several reasons: the grease loading is high and concentrated (many kitchens loading a shared system fast, needing frequent cleaning); responsibility is shared (no single tenant controls the whole shared system, so it can't be left to each unit alone); the fire risk is concentrated and collective (a duct fire in a shared system threatens many units and the whole centre); and multiple parties (the tenants and the centre management) all have a role, so they must coordinate. So it's a shared, at-scale version of extraction compliance, needing coordination rather than each unit acting alone. So because of shared systems, high loading, concentrated fire risk and multiple parties. So it's shared and at scale. This is general information, not legal advice.
Typically the centre management coordinates cleaning the shared system, with tenants keeping their own parts (canopies, filters, unit ductwork) - but the leases and arrangements govern, so responsibilities should be clearly defined and coordinated. On a shared food-court extraction system, no single tenant controls the whole thing, so responsibility has to be established and coordinated - it can't be left to each unit in isolation. In practice, the centre management typically coordinates (and often arranges) the cleaning of the shared/common extraction system, while the individual tenants keep their own parts cleaned (their canopies, filters and unit ductwork) and coordinate with the centre's arrangements. But the definitive split of responsibility is set by the leases and service arrangements between the centre and the tenants - which should clearly define who cleans the shared parts and who cleans the unit parts, so nothing (especially the shared system) falls between the parties. So it's usually centre-coordinated for the shared system and tenant-kept for the units - but check the lease/arrangements. So typically the centre for shared parts, tenants for their own. So the centre coordinates; tenants do their parts. This is general information, not legal advice; the arrangements govern.
Frequently - the heavy, concentrated grease loading of many kitchens on a shared system means a high risk-based cleaning frequency; the exact interval is matched to the loading, which in a busy food court is significant. A food court's extraction cleaning frequency, like any kitchen's, should be risk-based - matched to the grease loading - but in a food court that loading is high and concentrated: many kitchens cooking heavily (grilling, frying, wok) in one place load a shared system fast. So the cleaning frequency needs to be high to keep the concentrated grease and fire risk controlled - typically more frequent than a single, lighter-use kitchen. The exact interval depends on the specific loading (how many units, what cooking, how busy), assessed for the system. Under-cleaning a heavily-loaded shared food-court system is a serious, concentrated fire risk, so the frequency shouldn't be skimped. An extraction specialist can assess the loading and advise the appropriate frequency for the shared system and the units. So clean frequently, at a risk-based interval matched to the heavy loading. So often - matched to the heavy, concentrated loading. This is general information, not legal advice.
It's concentrated and shared - a lot of grease from many kitchens builds in a shared duct, and a duct fire there threatens not just one unit but many units and potentially the whole centre, so the risk is collective and serious. The fire risk in a food-court extraction system is both concentrated and shared. Concentrated: many kitchens cooking heavily load the shared ductwork with a large volume of grease, so a lot of combustible grease can build up in the common duct - a significant fuel load if under-cleaned. Shared: because the system serves multiple units (and runs through a large public building), a duct fire doesn't threaten just one outlet - it threatens many units connected to the system and potentially the whole shopping centre, a busy, populated building. So the consequence of neglect is collective and severe. And fire safety in such a multi-occupancy building is a shared responsibility (centre and tenants). This is why keeping the shared system cleaned to standard at an adequate frequency matters so much - the fire risk is too big and too shared to neglect. So it's a concentrated, shared risk to many units and the centre. So a shared, serious fire risk to the whole centre. This is general information, not legal advice.
Be part of the coordinated regime - know your responsibilities under the lease, keep your own parts (canopy, filters, unit ductwork) cleaned and evidenced, and coordinate with the centre's arrangements for the shared system, rather than acting in isolation. As a food-court unit operator, the key is to be part of the coordinated compliance regime, not to act alone. So: know your responsibilities (check your lease and the centre's arrangements for what you're responsible for - typically your own canopy, filters and unit ductwork - and what the centre handles for the shared system); keep your own parts cleaned to the TR19 Grease standard at the appropriate frequency, with certificates; and coordinate with the centre management's arrangements for the shared extraction (making sure the shared system is being cleaned, and that your unit fits into the overall regime). Don't assume the shared system is entirely someone else's concern to the point of ignoring it - the fire risk is shared. So play your part, keep your section compliant and evidenced, and coordinate with the centre. So know your part, clean and evidence it, and coordinate with the centre. So do your bit and coordinate with the centre. This is general information, not legal advice; your lease governs.
Not entirely - the units' own parts must be cleaned, but a shared system needs coordinated cleaning of the shared parts too; leaving the shared ductwork to fall between units means the highest-loading, highest-risk part goes neglected. Each unit cleaning its own parts (canopy, filters, unit ductwork) is necessary but not sufficient where the extraction is shared. On a shared or common system, the shared ductwork and extraction serve multiple units - so if each unit cleans only its own bit and assumes the shared parts are someone else's job, the shared system (the highest-loading, highest-risk part, carrying all the kitchens' grease) can fall between everyone and go neglected. So a shared system needs coordinated cleaning of the shared parts - typically organised by the centre management - alongside the units cleaning their own sections. The two fit together: units clean their parts, the centre coordinates the shared system, responsibilities are clear, and the whole thing is cleaned to standard. So no - units cleaning separately isn't enough for a shared system; the shared parts need coordinated cleaning too. So no; the shared system needs coordinated cleaning as well. So no - the shared parts need coordinating. This is general information, not legal advice; the arrangements govern.
Whether you manage a food court's shared system or operate a unit within it, the extraction has to be cleaned to standard. We clean shared and single-unit extraction to TR19 Grease, at the frequency the loading needs, with certificates for each - the evidence a coordinated regime relies on. Ask us about your food court's extraction cleaning. This is general information, not legal advice.
