SCDF KED Requirements for Commercial Kitchens in Singapore: A Complete Guide.

If you run a commercial kitchen in Singapore, fire safety is not something you can afford to ignore. One important requirement many kitchen operators need to know about is the SCDF KED .

Whether you manage a restaurant, hawker stall, hotel kitchen, school canteen, or food court outlet, understanding KED requirements can help you stay compliant, avoid fire risks, and keep your kitchen operating smoothly.

In this guide, we’ll explain what SCDF KED is, who needs it, what inspections usually cover, and how proper cleaning can help you pass.

What Is KED in Plain English?

KED stands for Kitchen Exhaust Duct .

In simple terms, it is the system in a commercial kitchen that removes:

  • Smoke 

  • Heat 

  • Grease-laden vapours 

  • Cooking fumes

This usually includes:

  • The kitchen hood

  • Baffle filters

  • Exhaust ducting

  • Exhaust fan

When cooking takes place, especially frying, grilling, and wok cooking, grease and oil particles are pulled up into the exhaust system. Over time, these particles stick to the inside of the hood and ducts.

If this grease is not cleaned regularly, it becomes a serious fire hazard .

That is why the Singapore Civil Defence Force (SCDF) has fire safety requirements for kitchen exhaust systems in commercial premises.

Why SCDF KED Requirements Matter

A dirty kitchen exhaust duct is more than just a hygiene problem — it can be dangerous.

Grease buildup inside the exhaust system can:

  • Ignite easily

  • Allow fire to spread quickly through the duct

  • Increase smoke and heat hazards

  • Affect ventilation performance

    Create unpleasant odours

  • Put employees, customers, and property at risk

SCDF requirements exist to reduce these risks and ensure commercial kitchens maintain a safe operating environment.

In short, KED compliance is about fire prevention , public safety , and responsible kitchen management.

Who Needs to Comply With SCDF KED Requirements?

In general, any premises in Singapore that operates a commercial kitchen with an exhaust system may need to comply with SCDF kitchen exhaust duct requirements.

This commonly includes:

Restaurants

Full-service restaurants, fast-food outlets, cafes, and eat-in establishments often use heavy cooking equipment that generates grease and smoke. These premises usually require regular KED inspection and cleaning.

Hawker Stalls

Hawker stalls that do frying, stir-frying, grilling, or other grease-producing cooking methods can also be subject to exhaust system maintenance requirements.

Hotels

Hotel kitchens often operate at high volume and may include multiple cooking stations. Because of the scale of operations, proper kitchen exhaust duct maintenance is especially important.

Schools

School canteens, institutional kitchens, and catering kitchens serving students and staff may also require proper exhaust duct upkeep to meet safety expectations.

Food Courts and Central Kitchens

Food court units and central kitchens typically have intensive cooking activity and shared safety responsibilities, making regular inspection and cleaning critical.

Hospitals, Caterers, and Industrial Kitchens

Large-scale institutional kitchens in healthcare, manufacturing, and catering environments also need to maintain safe, compliant exhaust systems.

Does Every Food Business Need It?

Not every food business has the same setup.

For example, a small beverage kiosk with no grease-producing cooking equipment may not have the same KED obligations as a full commercial kitchen.

The exact requirement depends on factors such as:

  • the type of cooking done

  • whether a kitchen hood and duct are installed

  • the volume of grease-laden vapours produced

  • the building’s fire safety requirements

  • SCDF and building management rules

If you are unsure, it is best to check with your fire safety consultant, building management, or a professional kitchen exhaust specialist familiar with Singapore regulations.

What Does the SCDF KED Inspection Usually Cover?

A kitchen exhaust duct inspection is generally focused on fire safety condition , system cleanliness , and overall functionality .

While exact requirements may vary depending on the premises and system design, inspections usually look at the following areas:

1. Grease Buildup in the Hood

Inspectors may check whether the kitchen hood has excessive grease deposits. Thick grease layers are a sign of poor maintenance and increased fire risk.

2. Condition of Filters

Filters help trap grease before it enters the duct. If filters are clogged, damaged, or missing, grease can accumulate faster inside the system.

3. Internal Duct Cleanliness

The inside of the exhaust duct is one of the most important inspection points. Hidden grease buildup inside the duct can be highly flammable and difficult to detect without proper access and cleaning.

4. Exhaust Fan Condition

The fan must be working properly to remove smoke, heat, and grease vapours effectively. Dirty fan blades or poorly maintained fans can reduce system performance.

5. Access Panels

Access panels allow technicians to inspect and clean the inside of the ducts. If access is insufficient, proper maintenance becomes difficult.

6. Fire Safety Features

Depending on the kitchen setup, inspectors may also look at whether related fire safety components are in place and properly maintained.

This can include:

  • fire-rated duct enclosures

  • fire suppression systems

  • clear maintenance records

  • proper installation condition

7. General Housekeeping and Maintenance

A poorly maintained kitchen often signals wider fire safety concerns. Cleanliness, maintenance routines, and documentation may all play a role.

Common Problems Found During KED Inspection

Some of the most common issues that may affect compliance include:

  • Excessive grease accumulation

  • Overdue cleaning

  • Clogged or damaged filters

  • Inaccessible duct sections

  • Leaking grease from ducts or hood joints

  • Poor exhaust airflow

  • Missing maintenance records

  • Neglected exhaust fan cleaning

These issues not only increase fire risk but may also lead to corrective actions, repeat servicing, or delays in approvals.

How Cleaning Helps You Pass KED Inspection

One of the most effective ways to prepare for a KED inspection is through regular professional cleaning .

1. Removes Flammable Grease

The main purpose of cleaning is to remove grease deposits from the hood, filters, ducts, and fan. This directly reduces fire risk and improves inspection readiness.

2. Improves Ventilation Performance

A clean exhaust system works more efficiently. Better airflow means smoke, heat, and cooking fumes are removed properly.

3. Prevents Hidden Duct Hazards

Much of the danger is inside the ductwork, where grease can build up out of sight. Professional cleaning ensures these hidden areas are addressed.

4. Supports Compliance

Regular servicing shows that the kitchen operator is taking fire safety seriously. Maintenance records and cleaning reports may also help support compliance efforts.

5. Extends Equipment Lifespan

Grease and dirt can strain the exhaust fan and other components. Cleaning helps your equipment run better and last longer.

6. Creates a Safer Kitchen Environment

A cleaner system contributes to a safer workplace for kitchen staff and lowers the chance of fire spreading through the exhaust line.
