Every commercial kitchen in Singapore must meet four non-negotiable requirements: annual specialist cleaning of kitchen exhaust ducts (KED), the correct portable extinguishers maintained under SS EN 3 and SS 578, LPG installations with gas-leak detection and automatic shut-off linked to suppression, and fire-rated compartmentation between kitchen and dining areas. Check your last KED service date, extinguisher tags, and suppression interlock status today. Equipment suppliers can advise on equipment that supports compliance.
TL;DR:
- Kitchen exhaust ducts must be professionally cleaned at least once every 12 months, with documented proof and interior duct cleaning included in the report.
- Fire extinguishers in commercial kitchens must conform to SS EN 3 and undergo regular visual checks, with professional servicing and hydrostatic testing documented by accredited agencies.
- LPG cylinders should be properly sited, equipped with functioning leak detectors linked to automatic shut-offs, and stored with adequate ventilation to prevent gas accumulation.
- Fixed fire suppression systems and compartmentation walls must meet specific fire-resistance ratings, with automatic gas shut-off interlocks tested and clearly documented in plans.
- Maintaining comprehensive, up-to-date records of all inspections, maintenance, and certifications is essential for passing SCDF inspections and avoiding penalties.

What are SCDF’s rules for kitchen exhaust duct cleaning?
The Singapore Civil Defence Force requires that kitchen exhaust ducts and hoods, including the interior surfaces, be degreased and cleaned by a specialist at least once every year. This is not a suggestion buried in a guidance note. It sits at the centre of fire safety requirements for KED installation and maintenance/fsm-briefing-2016—fire-safety-requirements-for-installation-and-maintenance-of-ked.pdf?sfvrsn=55752611_2), and owners or operators must retain documented records to prove it happened.
Grease buildup inside a duct is one of the most efficient fire accelerants you can find in a commercial kitchen. A flame that starts at the cooking line has almost nowhere to go if the duct is clean. If the duct is coated in months of accumulated grease, that same flame can travel the length of the ductwork in seconds, carrying fire into ceiling voids, service risers, or the floor above. The 12-month cleaning cycle exists because grease accumulation is progressive and largely invisible from ground level; you cannot judge duct condition by looking up at the hood.
There are also physical placement rules that matter as much as the cleaning schedule. Non-fire-rated KED must be sited at least 3 metres from LPG cylinders and never positioned directly above LPG storage, according to the same FSM briefing on KED installation. Unprotected openings near the duct run are similarly restricted, since any gap becomes a path for fire or smoke to spread beyond the kitchen envelope.
What should you actually ask a KED contractor before booking a job? Start here:
- Confirm they clean the interior ductwork, not just the visible hood surfaces and grease traps.
- Ask for a dated service report with the technician’s name and company registration.
- Request before-and-after photos of the duct interior as supporting evidence.
- Check that the report specifies the cleaning method used (chemical degreasing versus mechanical scraping).
- Ask how the 12-month renewal reminder works, so you are not chasing a lapsed certificate mid-inspection.
Inspectors generally want to see a chain of evidence, not just a single invoice. That means a service report bearing a clear date, some indication of the contractor’s accreditation, and confirmation that the work covered interior ductwork rather than a superficial wipe-down of exterior panels. A gap in any one of these three elements is often what escalates a routine check into a formal notice.
Pro Tip: Book your KED cleaning slightly ahead of the 12-month deadline, not on it. A contractor with a backlog can push your appointment out by two or three weeks, and an expired certificate on the day of an inspection is treated the same as no certificate at all.
Scheduling around your quieter trading days also reduces disruption. Most specialist contractors can complete a mid-sized kitchen’s duct system in a single closed session, but ceiling access and duct length both affect how long the job runs.
How many fire extinguishers does a commercial kitchen need?
Commercial premises must provide portable fire extinguishers; this obligation generally does not apply to private residential dwellings in the same way, since domestic kitchens fall under separate general fire safety expectations rather than the commercial servicing regime. Any premises operating as a food business, whether a hawker stall, restaurant kitchen, or food manufacturing floor, sits squarely within scope.
Where extinguishers are required, they must conform to SS EN 3, the Singapore standard governing portable extinguisher construction and performance. For kitchen environments with cooking oils, fats, and LPG-fired equipment, dry chemical extinguishers rated for both B (flammable liquid) and C (gas) fires are the typical choice, sized appropriately for the kitchen’s floor area and equipment density. Larger commercial kitchens with heavy fryer use often add a wet chemical extinguisher specifically rated for cooking oil fires, since dry chemical units are less effective once a deep-fat fryer fire is fully established.
Maintenance follows a two-tier cycle:
- Regular visual checks, carried out by the owner or a designated staff member, confirming the extinguisher is in place, the pressure gauge reads in the operating range, the pin and tamper seal are intact, and the unit is not damaged or obstructed.
- Periodic professional servicing, carried out by an approved servicing agency in accordance with SS 578, the code of practice covering inspection, maintenance, and recharging of portable extinguishers.
- Hydrostatic testing, required at set intervals depending on the extinguisher’s cylinder type, to confirm the pressure vessel remains structurally sound after repeated use or age.
Verifying a servicing agency is straightforward but often skipped. Legitimate agencies carry accreditation from recognised certification bodies such as TÜV SÜD PSB, and every serviced extinguisher should carry a tag showing the service date, the agency’s name, and the technician’s signature or stamp. SCDF itself has stated plainly that it does not endorse or certify products directly. Genuine certification comes from independent certification bodies, which means any supplier or contractor claiming their extinguisher is “SCDF-approved” is misrepresenting how the system works. Ask to see the servicing agency’s accreditation certificate before signing a maintenance contract, not after a problem surfaces.
What LPG rules apply to Singapore eating outlets?
LPG-fired cooking equipment carries its own regulatory layer, and Clause 10.1 of the Fire Code sets out exactly how cylinders must be sited, monitored, and shut down in an emergency. For eating outlets specifically, outdoor or ground-level siting is generally preferred for commercial installations, keeping cylinders away from enclosed indoor spaces wherever the kitchen layout allows it.
Gas-leak detection is not optional where LPG is used commercially. Detectors must be positioned to catch a leak early, and they must be linked to an automatic shut-off mechanism rather than relying on someone noticing a smell and reacting manually. Where the kitchen also has a fixed suppression system covering the cooking line, the shut-off must be interlocked with that suppression activation, so a fire event automatically cuts gas supply rather than leaving it running into an active blaze.
Remote emergency shut-off points also have to sit at a defined distance from the cylinder installation itself, giving staff a safe location to cut supply without approaching the fire source directly. Cylinder cabinets need adequate ventilation to prevent gas accumulation, and there are caps on how many cylinders can be stored together and how close that storage can sit to ignition sources, doorways, or drains.
A practical checklist for operators running LPG equipment:
- Confirm cylinder storage sits at the correct distance from KED, ignition sources, and building openings.
- Verify gas-leak detectors are installed and functioning, with a clear test date on record.
- Confirm the automatic shut-off is genuinely linked to suppression activation, not simply present as a separate manual valve.
- Check cabinet ventilation is unobstructed and cylinder quantities are within permitted limits.
- Keep contact details for your gas supplier and shut-off maintenance contractor accessible in the kitchen, not just in a filing cabinet.
Operators weighing new equipment purchases sometimes overlook that switching high-risk cooking stations to induction removes the LPG interlock question entirely for that piece of equipment, simplifying one corner of the compliance picture without touching the rest of the kitchen’s gas infrastructure.
When do kitchens need compartmentation or fixed suppression?
Fire doesn’t respect kitchen boundaries unless the building physically stops it, which is why the Fire Code sets minimum fire-resisting ratings for the walls and doors separating kitchens from dining areas and other occupied spaces. Fire Code guidance on fixed systems and special purpose rooms treats commercial kitchens as a distinct risk category requiring compartmentation, not an open-plan extension of the dining floor.
Fire-resisting walls, self-closing fire doors, and in some layouts roller shutters form the physical barrier. The rating required depends on the kitchen’s size, occupancy load, and its relationship to escape routes, but the underlying principle stays constant: a fire starting at the cooking line should be contained long enough for evacuation and suppression to work, rather than spreading unchecked into customer-facing areas within minutes.
Fixed automatic suppression systems for kitchen hoods, most commonly wet chemical systems designed for grease fires, are widely specified for commercial cooking lines with significant fryer or grill use. These systems must work alongside, not against, any building sprinkler coverage, and compatibility between the two is something a fire protection plan needs to address explicitly rather than assume.
The interlock requirement here mirrors the LPG rule in the previous section: suppression activation must automatically isolate the gas supply. For commercial kitchens running wet-chemical hood suppression, that cutoff is typically achieved through an electrical or electronic interlock, so the moment the system discharges, gas stops flowing to the affected cooking line without anyone needing to reach a manual valve. Warning signage at suppression system locations and clear labelling of shut-off points are also commonly expected as part of a complete installation.
- List compartment wall and door ratings against the kitchen’s occupancy classification.
- Specify the suppression system type and confirm sprinkler compatibility in writing.
- Document the gas interlock mechanism and how it is tested.
- Include signage locations and shut-off point labelling in the submission drawings.
Pro Tip: When submitting a fire protection plan to SCDF for a new kitchen fit-out, include the suppression-to-gas interlock wiring diagram alongside the equipment layout. Reviewers frequently query this specific detail, and having it ready the first time avoids a resubmission cycle.
What records do you need for an SCDF inspection?
Inspectors build a case from paperwork as much as from what they see on the kitchen floor. The essential file should hold KED service reports with dates and contractor details, extinguisher service tags plus hydrostatic test records, suppression system maintenance logs, and gas detector calibration certificates.
Missing or inadequate records rarely result in an immediate shutdown on a first visit, but they escalate quickly. A typical path runs from a verbal advisory, to a written notice with a compliance deadline, to fines, and in persistent or serious cases, court action. The FSM briefing on KED maintenance makes clear that enforcement follows directly from an owner’s failure to keep verifiable records, not just from the underlying hazard.
Practical organisation matters more than most operators expect:
- Keep digital copies of every service report, tag, and certificate in a single shared folder.
- Name files consistently, such as “KED_2026-03_ContractorName,” so date and scope are visible without opening the document.
- File contractor accreditation certificates alongside their service reports, not in a separate archive.
- Set calendar reminders 4 to 6 weeks before each annual renewal, giving contractors room to schedule you before the deadline lapses.
Practical compliance checklist and equipment choices
Compliance breaks down into a rhythm rather than a single annual scramble. Daily, staff should confirm extinguisher access is unobstructed and cooking areas are clear of grease spills. Weekly, check hood filters for visible buildup. Monthly, run the formal extinguisher pressure and seal check. Annually, book KED cleaning, extinguisher servicing, and suppression system maintenance together where scheduling allows, so certificates renew on a predictable cycle.
Equipment choice genuinely affects your risk profile, not just your energy bill. Kitchens running induction cookers alongside LPG equipment carry one fewer gas interlock to manage on the induction line, since there’s no open flame or gas leak risk at that station. That doesn’t remove the need for extinguishers or suppression elsewhere in the kitchen, but it does reduce the number of points where an LPG fault could originate.
- Match extinguisher type to your dominant cooking method (oil-heavy fryer lines lean towards wet chemical).
- Treat contractor accreditation as a standing requirement, not a one-off check.
- Review your fire protection plan whenever equipment layout changes, not only at initial fit-out.
- Keep KED, extinguisher, and suppression renewal dates on one shared calendar.
Commercial kitchen appliance suppliers provide induction cookers to operators reviewing how their equipment mix affects fire risk and compliance planning.
What are SCDF’s staff training and fire drill guidelines?
Equipment and paperwork only carry a kitchen so far without trained people responding correctly under pressure. SCDF fire safety guidance places clear weight on staff training and regular fire drills as part of a kitchen’s overall fire safety posture, not as a separate add-on to the physical measures already covered.
Training should cover recognising the early signs of a kitchen fire, knowing the location and correct use of the nearest extinguisher, and understanding how to activate manual call points and reach the LPG emergency shut-off without hesitation. Staff working directly at fryer or grill stations need specific instruction on fighting a small grease fire safely: smothering the pan with a lid and cutting the heat, never applying water, which is the expert-recommended response to a grease fire and applies just as strongly in commercial settings as at home.
Fire drills should be run at a frequency that matches staff turnover, which in Singapore’s foodservice sector tends to be high. A drill schedule tied only to an annual calendar date risks leaving newer staff untested. Practical operators run a brief walkthrough with each new hire during onboarding, then a full drill involving the whole shift team at least once or twice a year, timed to include evacuation to the assembly point and a headcount check.
What’s the evacuation plan for a kitchen fire?
A kitchen fire response plan needs to answer three questions instantly: who raises the alarm, who fights the fire if it’s safe to do so, and who evacuates whom. Delay at any one of these points is what turns a contained stovetop flare into a building-wide incident.
The first move for any kitchen fire beyond a small, controllable flare is to activate the nearest manual call point and alert other staff, rather than attempting to fight a fire that has already spread beyond the immediate cooking vessel. Unattended or escalating cooking fires are consistently cited as the leading cause of kitchen fire incidents, which is exactly why staying with active cooking and reacting within seconds matters more than any piece of fixed equipment.
Evacuation routes from the kitchen should be kept physically clear at all times, not just during a fire safety audit. That means no stacked crates or delivery pallets blocking the path to the nearest exit, and no propped-open fire doors defeating the compartmentation the building was designed around. Assembly points outside the building need to be known to every staff member, including part-timers and new hires, and a simple headcount procedure at the assembly point confirms everyone made it out. For kitchens operating within larger premises such as shopping centres or hotels, the kitchen’s evacuation plan should align with the building’s overall fire evacuation procedure rather than operate as an independent, disconnected process.
What fire safety signage is required in commercial kitchens?
Signage in a commercial kitchen serves a specific function during the seconds that matter most: pointing staff, without hesitation, to extinguishers, shut-off points, and exits. SCDF’s Fire Code framework expects clear identification of fire safety equipment locations as a standard part of kitchen fit-outs, alongside the physical equipment itself.
Extinguisher locations need visible signage positioned above or immediately adjacent to the unit, so staff can locate it through smoke or in a hurry rather than searching along a wall. LPG emergency shut-off points require clear labelling identifying their function, given how critical fast, unambiguous access becomes during a gas-related incident. Where a fixed suppression system covers a hood line, signage indicating the system’s presence and its manual activation point, if one exists, is commonly expected as part of a complete installation.
Evacuation route signage follows standard building-wide fire safety conventions, directing occupants towards the nearest usable exit rather than assuming familiarity with the layout. In a commercial kitchen, this matters more than in most other rooms, since kitchens are often laid out with equipment blocking sightlines and multiple staff working with their backs to the exit route during service. Signage should be checked periodically for visibility, since steam, grease film, or relocated equipment can obscure a sign that was perfectly placed at fit-out.
How do you get SCDF approval for new kitchen fire safety installations?
New kitchen fit-outs and significant modifications to fire safety systems, including changes to suppression coverage, LPG installations, or compartmentation, typically require submission to SCDF as part of the plan approval process before work proceeds.
A submission generally needs to demonstrate how the proposed layout meets the Fire Code’s requirements across compartmentation ratings, suppression system specification and its gas interlock mechanism, LPG cylinder siting and detection, and extinguisher provision matched to the kitchen’s risk profile. Drawings should show equipment placement clearly enough for a reviewer to check setback distances, such as the KED-to-LPG separation, without needing to request clarification.
Modifications to an existing, previously approved kitchen carry the same scrutiny as a new build if they change the fire safety envelope, meaning adding a new fryer line, relocating LPG storage, or upgrading suppression coverage should trigger a fresh review rather than being treated as routine maintenance. Operators who skip this step because “it’s just a new appliance” often discover the gap during a later inspection, when the installed equipment no longer matches the approved plan on file.
Working with contractors and equipment suppliers familiar with SCDF’s documentation expectations tends to shorten the approval cycle, since incomplete or vaguely specified submissions are a common reason reviews stall.
What Singapore’s kitchen fire rules get wrong in practice
The gap between what operators think SCDF’s kitchen fire rules demand and what actually gets enforced is wider than most guidance admits. Kitchens rarely fail inspections because they lack an extinguisher. They fail because the paperwork trail behind that extinguisher, the KED cleaning, and the suppression interlock has a hole in it somewhere, and that hole is what an inspector finds first.
Conventional advice treats compliance as a checklist to complete once. The evidence points the other way: KED cleaning lapses silently after 12 months, extinguisher tags expire without fanfare, and gas interlocks get disconnected during unrelated repairs and never reconnected. The kitchens that stay compliant are the ones that treat records as a living file, reviewed monthly, not an annual scramble before a renewal deadline.
If there’s one priority above the rest, it’s the interlock between suppression and gas shut-off. It’s the least visible requirement and the one most likely to have quietly failed without anyone noticing. Equipment choice plays into this too. A kitchen running fewer LPG stations simply has fewer interlocks that can fail.

How Superior Kitchen Equipment supports your compliance plan
Reducing your kitchen’s exposure to fire risk often starts with the equipment itself, not just the paperwork around it. Suppliers provide appliances that shape that risk profile directly, from induction cooking equipment that removes open-flame and LPG interlock concerns at that station, to commercial ovens and fryers designed with ventilation and grease-load compatibility in mind for KED planning.
If your kitchen is weighing a shift away from gas-heavy cooking lines, the Standing Induction Cooker is worth reviewing against your current LPG setup, since it sidesteps the gas detection and shut-off interlock questions entirely at that station. For operators keeping gas cooking as part of the layout, the 2 Ring Standing Gas Stove and the 6 Ring Gas Stove both suit different kitchen scales, and either can be specified alongside the correct interlock and detection setup your plan submission requires.
Beyond the cooking line, the full product catalogue covers refrigeration, ovens, and worktables suited to commercial fit-outs planning a compliance-focused layout from the ground up. Visit the showroom to see equipment options in person, request product specifications for your next plan submission, or get in touch to discuss which appliances fit your kitchen’s fire safety planning.
Official SCDF documents worth keeping on file
Four documents cover most of what an inspector or a plan reviewer will ask to see. Keep digital copies on hand, not just printed versions in a site folder.
- Clause 10.1 on LPG cylinder installations, covering siting, detection, and shut-off linkage.
- The Fire Code handbook chapter on fixed systems, covering compartmentation and suppression.
- The Fire Code 2023 landing page, the entry point for the full regulatory framework and certification body guidance.
Bring the KED and LPG documents to any inspection where those systems are in scope, and reference the Fire Code handbook directly during plan submissions involving suppression or compartmentation changes.

FAQ
What are the best practices for kitchen fire safety?
Keep KED cleaned annually by a specialist, maintain extinguishers monthly with annual professional servicing, and train staff to stay with active cooking rather than leaving it unattended, since unattended cooking is the leading cause of kitchen fires. Combine that with working gas-leak detection and a clear evacuation plan staff have actually practised.
What are the fire safety regulations for commercial kitchens in Singapore?
Commercial kitchens must maintain annual KED cleaning with retained records, provide extinguishers conforming to SS EN 3 with SS 578 maintenance, and meet LPG siting and interlock rules under Clause 10.1 where gas cooking is used. Compartmentation and suppression requirements apply on top of these depending on kitchen size and layout.
Have SCDF’s kitchen fire rules changed recently?
The Fire Code 2023 consolidates current requirements for KED, extinguishers, LPG installations, and suppression systems, and operators should check the Fire Code 2023 landing page directly for the latest clauses rather than relying on older guidance documents. Rules on specific technical details, such as setback distances, are periodically clarified through FSM briefings rather than wholesale rewrites.
Does a fire extinguisher need to be approved by SCDF?
SCDF does not personally endorse or approve individual extinguisher products; it states this directly on its Fire Code 2023 site. What matters is that the extinguisher conforms to SS EN 3 and is serviced by an agency accredited through a recognised certification body such as TÜV SÜD PSB, not a supplier’s own “SCDF-approved” claim.
Can induction cooking help with SCDF compliance?
Switching high-risk cooking stations to induction removes the open-flame and LPG interlock question at that specific station, simplifying one part of a kitchen’s compliance picture. It doesn’t remove the need for extinguishers, KED maintenance, or compartmentation elsewhere in the kitchen, and Superior Kitchen Equipment’s Standing Induction Cooker is one option operators review when planning that shift.
