Designing Food Premises for Cleanability

Under FSANZ Standard 3.2.3, food premises, fixtures, fittings and equipment must generally be designed and constructed so they can be effectively cleaned and, where needed, sanitised. In practice that means smooth, impervious, non-absorbent surfaces; sealed junctions and coving; a layout that separates clean and dirty flows; and dedicated hand wash basins with warm running water. Design decisions made before fit-out are usually far cheaper than retrofitting later, so confirm requirements with your local council early. Key takeaways: Standard 3.2.3 (which applies in Australia only) requires premises, fixtures, fittings and equipment to be designed and constructed so they can be effectively cleaned and, where necessary, sanitised.. Surfaces in food-handling and wash-up areas should generally be smooth, impervious, non-absorbent, free of cracks and crevices, and resistant to the water, heat and chemicals used to clean them.. Coving at floor-to-wall and floor-to-plinth junctions removes the sharp corners where grease and debris collect, and is especially useful where floors are hosed down.. Hand wash basins must generally be permanent fixtures supplied with warm running potable water, soap and a hygienic means of drying hands, located where food handlers actually work.. Approve your design and materials with your local council or state food regulator before fit-out — requirements and approval steps vary by jurisdiction, and retrofitting is costly.. Suitable cleanable finishes by area: Area or element, Suitable finish. Floors (wet food and wash areas) — Sealed commercial tiles, epoxy/polyurethane resin, or welded vinyl with coved skirting. Walls — Stainless steel, FRP panels, or sealed/painted substrate or tiling with sealed joints. Ceilings — Flush-set plasterboard with washable paint, or hygienic ceiling panels. Food-contact surfaces — Food-grade stainless steel (commonly grade 304, or 316). Junctions — Coving at floor junctions plus sealed bench, splashback and service-penetration joints. What Standard 3.2.3 actually requires Standard 3.2.3 Food Premises and Equipment sits in Chapter 3 of the Australia New Zealand Food Standards Code and applies to food businesses in Australia (Chapter 3 does not apply in New Zealand, which has its own requirements). Its central design principle is straightforward: everything a food business builds or installs should generally be capable of being cleaned, and where food safety demands it, sanitised. That covers the building itself, plus fixtures, fittings, equipment and food transport vehicles. The Standard is largely outcome-based rather than prescriptive. It tells you the result you must achieve — a surface that can be effectively cleaned, a basin that lets staff wash their hands properly — but usually leaves the exact materials and dimensions to you and your designer. That flexibility is useful, but it also means an environmental health officer (EHO) assesses your fit-out against the outcome, not a fixed checklist. FSANZ publishes interpretive guidance in Safe Food Australia to help businesses and regulators apply the clauses consistently, and many councils also reference the voluntary Australian Standard AS 4674 for design, construction and fit-out. Always confirm what your council expects. Cleanability is not only a legal requirement. Surfaces and layouts that resist soil, drain freely and can be reached with a mop or cloth make daily cleaning faster, reduce the harbourage of pests and pathogens, and lower the risk of cross-contamination. Design for cleanability and you generally make compliance, hygiene and staff efficiency easier at the same time. Applies to premises, fixtures, fittings, equipment and food transport vehicles in Australia.. Outcome-focused: the surface or fixture must be able to be effectively cleaned (and sanitised where needed).. Interpretive guidance is set out in FSANZ's Safe Food Australia; AS 4674 is a commonly referenced fit-out standard.. Smooth, impervious, cleanable surfaces The workhorse concept in cleanable design is the smooth, impervious, non-absorbent surface. In food-handling and wash-up areas, floors, walls, ceilings and benches should generally be free of open cracks and crevices, non-porous so they do not soak up grease, food or water, and durable enough to withstand the hot water, steam, detergents and sanitisers used to clean them. For floors in preparation and wash areas, common compliant finishes include sealed commercial-grade tiles with impervious grout, epoxy or polyurethane resin systems, and welded sheet vinyl with coved skirting. Bare concrete, timber floorboards and unsealed grout are usually poor choices in wet food areas because they absorb moisture and trap soil. Walls are frequently finished in stainless steel, fibre-reinforced plastic (FRP) panels, sealed and painted solid substrates, or tiling with sealed joints. Ceilings should be smooth, sealed and cleanable — flush-set plasterboard with washable paint or purpose-made hygienic ceiling panels are typical. Contact surfaces that touch food deserve particular care. Food-grade stainless steel (commonly grade 304, or 316 where extra corrosion resistance matters) is the default for benches, splashbacks and equipment because it is smooth, durable and easy to sanitise. Whatever materials you choose, remember that the finish only stays cleanable if joints, seams and penetrations are properly sealed — an otherwise perfect wall panel fails the test if grout is missing or silicone has perished. Food-area surfaces: smooth, impervious, non-absorbent, crevice-free and resistant to cleaning agents.. Floors: sealed tiles, epoxy/polyurethane resin, or welded vinyl — avoid unsealed concrete or timber in wet areas.. Food-contact surfaces: food-grade stainless steel (e.g. grade 304/316) is the usual benchmark.. Seal every joint, seam and service penetration — unsealed gaps defeat an otherwise cleanable finish.. Coving and sealed junctions Sharp internal corners are where cleaning fails. The 90-degree angle between a floor and a wall, or around the base of a plinth, collects grease, water and food debris that a mop skips over. Coving — a curved or angled fillet that turns the junction into a continuous, gently radiused surface — removes that trap and lets water and soil flow away instead of pooling. Coving is particularly valuable where floors are cleaned by flushing or hosing, because a coved junction directs water toward the floor drain rather than letting it wick up behind skirtings. It also helps keep pests out of wall cavities. You will commonly see coved skirting integrated with resin or vinyl floors, purpose-made cove tiles, or preformed stainless cove strips. The same logic applies beyond the floor. Seal the junctions where benches meet walls, where splashbacks meet benchtops, and around pipes, conduits and fixings that pass through walls or ceilings. Continuous, sealed transitions mean fewer places for moisture and bacteria to hide and a much faster, more reliable clean at the end of each shift. Cove floor-to-wall and floor-to-plinth junctions to eliminate uncleanable corners.. Coving is especially important where floors are hosed or flushed, aiding drainage to floor wastes.. Seal bench-to-wall, splashback and service-penetration junctions the same way.. Layout and workflow Cleanability is as much about layout as materials. A well-planned kitchen moves product in one broad direction — from delivery and storage, through preparation and cooking, to service — so that raw and ready-to-eat foods, and clean and dirty flows, do not cross. Separating these paths reduces cross-contamination and means each zone can be cleaned without contaminating another. Leave enough clear space around and beneath equipment to actually clean it. Benches and heavy equipment on sealed plinths, or mounted on legs with adequate clearance (or on castors so they can be rolled out), let staff reach the floor and rear surfaces. Mobile equipment is often easier to clean around than fixed units crammed against a wall. Position waste storage, chemical storage and cleaning stores so they are accessible but separated from food handling and storage. Think about where water goes. Graded floors that fall to floor wastes prevent pooling, and a dedicated cleaners' sink or wash bay keeps mop water away from food areas. Good natural or artificial lighting over work and wash areas helps staff see — and therefore remove — soil. A layout designed around how the space will be cleaned, not just how food is produced, pays back every single day. Plan a logical one-directional flow; separate raw from ready-to-eat and clean from dirty.. Provide clearance around and under equipment (plinths, legs or castors) so floors and rears can be cleaned.. Grade floors to floor wastes and provide a dedicated cleaners' sink separate from food sinks.. Hand wash basins: number, placement and fit-out Dedicated hand washing facilities are one of the few areas where Standard 3.2.3 is quite specific, because handwashing is a frontline control against contamination. Hand wash basins must generally be permanent fixtures connected to a supply of warm running potable water, be of a size and design that allows a person to wash their hands easily, and be provided with soap and a hygienic means of drying hands (single-use paper towel or an air dryer). Just as important is where they go. Basins should be located wherever food handlers work and their hands are likely to be contaminated, and in or immediately adjacent to toilet areas. A basin tucked in a back corner that staff have to walk past raw product to reach will not be used consistently. Provide enough basins that handwashing is convenient at each work zone, and keep them exclusively for handwashing — a hand basin is not a food-prep or equipment-washing sink, and combining the two invites contamination. Specify the fit-out for hygiene: a splashback and coved or sealed junction behind the basin, hands-free or wrist/elbow-operated taps where practical, a wall-mounted soap dispenser and paper towel holder, and a bin nearby. Warm water encourages proper washing and helps lift grease. Confirm the exact number and placement expected in your fit-out with your local council, as interpretations can vary. Permanent basins with warm running potable water, soap and a hygienic hand-drying method.. Located where food handlers work and adjacent to toilets — convenient, not tucked away.. Reserved solely for handwashing; never doubled up as a food or equipment sink.. Fit out with splashback, sealed junctions, and wall-mounted soap and paper towel.. Services, equipment and getting design approval Cleanable premises also depend on the services behind the walls. Standard 3.2.3 generally requires an adequate supply of potable water where water is used for food or cleaning, effective disposal of sewage and waste water, suitable garbage and recyclables storage that can itself be cleaned, adequate ventilation (mechanical exhaust over cooking is usually needed to control grease-laden vapour and condensation), and lighting sufficient for the activities being carried out. Grease traps and trade waste drainage are typically also governed by your water authority and plumbing rules. Fixtures, fittings and equipment must be designed, constructed, located and, if necessary, installed so they can be cleaned and, where needed, sanitised. Chosen well, commercial equipment carrying recognised hygienic-design or food-equipment certification makes this easier. Where equipment connects to services — for example a dishwasher or combi oven — install it so the connections and the space around it stay cleanable. Before you build, engage your local council's environmental health team early. Many councils require you to submit plans and material specifications for a food premises fit-out for assessment, and separate development, building and plumbing approvals often apply. Australian design and fit-out guidance from state health departments, councils and AS 4674 can help you specify surfaces and layouts that will pass. Because requirements and approval processes vary between states, territories and councils, always confirm the specifics with your local council and state or territory food regulator before committing to a design. Provide potable water, waste and sewage disposal, cleanable garbage storage, ventilation and adequate lighting.. Equipment must be designed, located and installed to be cleaned and, where needed, sanitised.. Submit plans and material specs to council early; development, building and plumbing approvals may also apply.. Requirements vary by jurisdiction — confirm with your council and state/territory regulator.. Worked examples: Planning a new cafe kitchen fit-out: Before fitting out a new cafe kitchen, the owner submits plans and material specifications to the council's environmental health team. The design uses a welded-vinyl floor with coved skirting graded to a floor waste, FRP wall panels with sealed joints, food-grade stainless benches, and a dedicated hand basin at the prep zone with warm water, soap and paper towel. Getting sign-off first avoids costly retrofitting. Checklist: Layout separates raw from ready-to-eat and clean from dirty flows. Floors are smooth, impervious, non-absorbent and graded to floor wastes. Walls and ceilings are smooth, sealed and washable. Coving installed at floor-to-wall and floor-to-plinth junctions. Bench, splashback and service-penetration junctions are sealed. Food-contact surfaces are food-grade stainless steel or equivalent. Hand wash basins are permanent, with warm running potable water. Each basin has soap and a hygienic hand-drying method. Hand basins are located at work zones and near toilets, and used only for handwashing. Equipment is on plinths, legs or castors with clearance for cleaning. Adequate lighting and ventilation (with exhaust over cooking) provided. Plans and materials approved by council before fit-out began. Common mistakes: Using absorbent finishes — unsealed concrete, timber or porous grout — in wet food-handling or wash areas.. Leaving sharp 90-degree floor-to-wall corners uncoved, so grease and water collect where mops cannot reach.. Installing too few hand wash basins, or putting them somewhere staff must pass raw food to reach.. Doubling a hand wash basin as a food-prep or equipment-washing sink, creating a contamination route.. Cramming equipment tight against walls or the floor with no clearance, making the floor and rear impossible to clean.. Forgetting to seal joints, seams and service penetrations, so an otherwise cleanable surface traps moisture and soil.. Ordering fit-out before submitting plans to council and then having to rip out and retrofit non-compliant surfaces..
