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.. 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
