Kitchen Lighting & Ventilation

Kitchen lighting and ventilation are food-safety controls, not just comfort features. Good lighting lets staff see contamination, read labels and clean effectively; good ventilation removes heat, grease-laden vapour and moisture that would otherwise foul surfaces and feed mould and pests. In Australia, both are governed by a mix of the Food Standards Code, Australian Standards and building codes. This guide explains what the standards require and how to keep your kitchen compliant. How Much Lighting Does a Commercial Kitchen Need? Standard 3.2.3 of the Food Standards Code requires food premises to have enough light to allow food to be handled safely and hygienically and to let the premises be cleaned effectively. For practical guidance on levels, the lighting standard AS 1680 recommends around 320 to 500 lux at food-preparation surfaces — bright enough to see dirt, spot contamination and read use-by dates and allergen labels without straining. Under-lit prep areas are a genuine hazard: staff cannot clean what they cannot see. When assessing your kitchen, check that task lighting over benches, the pass and wash-up areas is bright and even, with no dim corners where debris can hide. What Light Fittings Are Required Above Food? Any light fitting above exposed food must be shatter-resistant or protected, so that a broken lamp cannot shower glass into food. Use shatter-proof tubes or fit diffusers and covers over standard lamps. Beyond the safety requirement, maintenance matters: Replace failed lamps promptly to keep light levels adequate. Keep diffusers and covers clean — accumulated dust and grease on fittings reduce light and are a frequent environmental health officer (EHO) finding. Include light fittings in your cleaning schedule so they are wiped down on a set frequency. Dusty, greasy light covers over a prep bench signal a wider cleaning problem to an inspector, so fold them into your cleaning routine . What Does AS 1668 Require for Ventilation? Commercial kitchen ventilation in Australia is governed by AS 1668.2 , which sets mechanical ventilation and exhaust requirements. Two principles matter most: Exhaust hoods must capture cooking emissions — the canopy over cooking equipment must be sized and positioned to draw away heat, smoke and grease-laden vapour at the source. Make-up air must replace what is exhausted. If a system pulls large volumes of air out without supplying fresh air back in, the kitchen goes into negative pressure, which causes doors to slam, extraction to fail and odours to be drawn in from other areas. Effective ventilation keeps surfaces from becoming greasy and damp, which in turn keeps them cleanable and denies pests the conditions they favour. It is a food-safety control as much as a comfort one. How Do You Maintain Lighting and Ventilation? Both systems degrade without a maintenance schedule. Grease build-up in an exhaust system is also a serious fire risk, which is why insurers ask for cleaning records. Set up a routine: Clean baffle filters regularly — often weekly in busy kitchens. See our range hood filter cleaning guide for frequencies. Book quarterly specialist exhaust cleans of the ductwork and fan, and keep the certificates. Replace and clean light fittings on a set schedule. Store all certificates and maintenance records for insurance and inspection. A digital log of these tasks means nothing is missed and every certificate is retrievable when your insurer or an inspector asks. FoodSafety HQ can schedule the recurring work and store the paperwork in one place. How Do Lighting and Ventilation Fit With Building Codes? Lighting and ventilation also intersect with the National Construction Code (which incorporates the Building Code of Australia) and state plumbing and mechanical codes. For a new build or major renovation, ventilation design should be signed off by a qualified mechanical engineer to ensure exhaust rates, make-up air and duct routing comply. Getting this right at design stage is far cheaper than retrofitting a system that cannot cope with your cooking line. Australia's food-hygiene framework is set by Food Standards Australia New Zealand , while construction and ventilation standards sit alongside it. How Ventilation Supports Pest and Mould Control Ventilation does quiet food-safety work that is easy to miss. By removing heat, steam and grease-laden vapour, a well-designed system keeps surfaces dry and clean rather than damp and greasy. That matters because moisture and grease create the exact conditions pests and mould need to thrive. Poor ventilation leaves condensation on walls and ceilings, grease film on surfaces, and warm, humid corners — all of which attract cockroaches and encourage mould growth. In this sense, ventilation is part of your integrated pest management program , not a separate concern. Kitchens that struggle with persistent grease film or condensation should look at their ventilation before assuming the problem is purely a cleaning one. Emergency and Task Lighting Considerations Lighting design should also account for what happens when the main lights fail. Emergency lighting and clearly lit exits are building-code requirements that keep staff safe during a power outage or evacuation, and they intersect with your overall premises compliance. Beyond emergencies, think about task lighting for specific high-risk jobs — a well-lit pass helps staff spot a wrong plate or an allergen-marked dish, and bright wash-up lighting helps staff see whether equipment is actually clean. Good lighting is cheap insurance against the small errors that lead to contamination, so treat it as a working tool rather than a background utility, and keep fittings maintained through your cleaning schedule .
