Kitchen Hood Safety Checklist in Singapore

A kitchen hood looks simple, but most safety issues happen because of wrong installation, poor ducting, and grease buildup over time. Use this checklist for home kitchens (HDB/condo/landed) and—if you operate a small F&B / central kitchen—pay extra attention to the commercial items at the end.

Note: Requirements can differ depending on whether you’re residential or commercial. The commercial items below reference Singapore’s guidance for kitchen exhaust systems and fire prevention.

1) Before you buy: product safety checks

✅ Confirm the hood type fits your cooking + kitchen layout

• Ducted (extraction to outdoors): best for heavy cooking; removes heat, smoke and grease more effectively.

• Recirculating (carbon filter): easier to install but relies heavily on filter condition—safety/odour issues rise when filters are old.

✅ Use locally suitable electrical specs

• Singapore homes typically use 230V / 50Hz appliances—avoid questionable imports with unclear ratings.

• If you’re unsure, buy from reputable sellers and keep proof of purchase for warranty/service.

✅ If the product is regulated, check for required marks/registration

Singapore regulates certain household electrical/gas products as “Controlled Goods” (these require compliance and marking). As a buyer, the practical habit is: check the product’s official compliance labeling when applicable.

2) Installation safety: mounting height, structure, and clearance

✅ Correct mounting height above hob (don’t guess)

• Follow the manufacturer’s minimum height.

• As a practical reference many installers use:

  • ~65–75 cm above electric/induction hobs

  • higher above gas hobs depending on the hood/manual
    (Always prioritise the hood’s own manual and the hob manufacturer’s guidance.)

✅ Secure mounting into solid structure

• Don’t mount into weak cabinet panels alone.

• Wall-mounted hoods should be anchored to a proper wall stud / reinforced backing.

• Island hoods must be supported by a structure designed for the hood’s weight + vibration.

✅ Keep safe clearance from heat sources

• Avoid placing the hood where the duct or wiring sits too close to hot surfaces (hob, oven flue paths, etc.).

3) Ducting & venting: the “invisible” safety risks

If you use a ducted hood, ducting is where performance and fire risk are won or lost.

✅ Use proper duct size + minimise bends

• Undersized ducts or too many sharp bends reduce airflow and increase grease deposit.

• Many residential installers commonly use 6-inch ducting for better flow (check hood outlet size; don’t downsize).

✅ Prefer smooth, rigid ducting

• Smooth metal ducts reduce grease trapping vs. overly flexible ducting that kinks and collects oil.

✅ Vent to outdoors without causing nuisance

For commercial kitchens/food shops, NEA’s Code of Practice highlights exhausting treated air outdoors and avoiding discharge that affects neighbours.
(For homes, the same common-sense principle applies: avoid blowing directly into a neighbour’s window or internal airwell where it becomes a nuisance.)

4) Fire safety: grease is the #1 enemy

✅ Never allow grease to build up (filters + hood interior + duct)

Grease accumulation in exhaust systems is a known fire cause in kitchens. Singapore agencies emphasise regular maintenance to prevent fires.

✅ Avoid “open flame show” under the hood

• Don’t flambé under a cooker hood.

• Keep curtains, paper towels, and plastic away from the hob area.

✅ If you run a food business: follow the documented cleaning requirement

Guidance referenced by Singapore authorities states that exhaust ducts (including interior) and kitchen hoods should be degreased and cleaned at least once every 12 months, with records kept for verification.

5) Electrical safety checklist (simple but crucial)

✅ Dedicated power point + proper earthing

• Avoid multi-plug adapters for built-in appliances.

• Ensure wiring is not pinched or rubbing on sharp metal edges.

✅ Let licensed professionals handle electrical changes

If installation involves new wiring, relocation of points, or concealed routing, engage a qualified electrician/installer—especially for built-in cabinetry jobs.

6) Maintenance schedule you can actually follow

For homes (typical usage)

• Grease filters (metal): wash every 2–4 weeks (more often if you stir-fry daily)

• Carbon filters (recirculating hoods): replace every 3–6 months (depends on cooking load)

• Hood underside + oil collector: wipe weekly

• Duct check (ducted): inspect every 6–12 months for grease and airflow drop

For heavy cooking / small F&B

• Follow your service provider’s recommendation and ensure you meet the at-least-annual degreasing/cleaning expectation for hood + ducting, keeping records.

7) Quick “Pass/Fail” safety checklist

PASS if you can tick all:

• Hood mounted at manufacturer-recommended height (not guessed)

• Hood firmly anchored (not just into thin cabinet board)

• Ducting (if any) is correct size, smooth, minimal sharp bends

• Exhaust route does not create nuisance / blow into enclosed space

• Grease filters cleaned regularly; hood interior not oily

• No oil dripping from hood/duct (this is a red flag)

• Power connection is stable; no loose adapters; wiring protected

• For businesses: hood + duct degreased/cleaned at least annually + records kept
