Electrical safety in a working kitchen: what actually goes wrong
A commercial kitchen packs a lot of electrical energy into a small, wet, hot and greasy space. Appliances are plugged in and out all day, leads run across tiled floors that get mopped far more often than any office, and equipment is shared between people who may have started that week. That combination is why hospitality deserves its own look at electrical safety rather than a generic workplace approach.
The starting point is the same as anywhere in New Zealand: testing and tagging is one useful way to check that electrical equipment is safe, but it is not mandatory. What is legally required is that equipment is electrically safe and maintained in a safe condition. Everything below is about meeting that duty sensibly in a café, restaurant, bar, hotel, motel or catering operation.
What the law says for hospitality venues
WorkSafe New Zealand does not single out cafés or restaurants with a separate testing rule, and it is worth saying plainly that WorkSafe does not require hospitality businesses to test and tag. What it says is that the PCBU decides whether to test and tag, and that the legal duty is about the equipment being safe and maintained in a safe condition. It also notes that whether or not equipment is tested and tagged, it still needs RCD protection in certain circumstances, such as outside in the damp.
AS/NZS 3760 is a Standard a PCBU can choose to follow to demonstrate compliance. In a kitchen, where water, heat and grease are everywhere, most operators find it a useful framework rather than a burden. If you have not read it before, our explainer on how RCD protection actually works and our notes on how often electrical equipment needs checking are good companions to this piece.
The equipment that carries the most risk
| Equipment | Why it matters |
|---|---|
| Kitchen appliances (ovens, fryers, grills, mixers, slicers) | High current, heat, grease and constant plugging in and out |
| Refrigeration (fridges, freezers, display cabinets) | Condensation and compressor load; leads often hidden behind units |
| Dishwashers and glasswashers | Water and steam directly around the connection point |
| Coffee machines | Water plus heat plus heavy daily use and frequent cleaning |
| Portable heaters | High current draw, often on extension leads or in tight spots |
| Extension leads and power boards | Overloading, trailing across wet floors, mechanical damage |
| Point-of-sale and back-office equipment | Lower risk, but leads and chargers still get damaged |
Wet floors, heat and grease
Each of these three conditions attacks electrical equipment in a different way. Water and steam get into connections and enclosures. Heat dries and cracks insulation. Grease builds up on cords and around plugs, holds dirt and makes visual inspection harder. Add the constant movement of equipment during cleaning and service, and you have an environment that shortens the working life of leads and plugs well below what the same item would see in an office.
The practical consequence is that a damaged cord in a kitchen can be genuinely hard to spot, which is exactly why routine visual checks matter alongside any testing programme. A cable that looks fine at a glance can already have failed internally.
RCD protection in wet areas
Kitchens, sculleries, outdoor dining areas and any part of a venue that gets washed down are the places where RCD protection earns its keep. RCD protection is a separate control from testing and tagging: equipment still needs it in certain circumstances, such as outside in the damp, whether or not it has been tested and tagged. RCDs should be checked using the test button every day, including the RCD on a portable socket-outlet assembly. If you want help confirming what is protected in your venue, a dedicated RCD testing service is the straightforward way to find out.
Shared equipment and high staff turnover
Hospitality has two features that quietly undermine safety systems. The first is shared equipment: a single stick blender might be used by five people across three shifts. The second is turnover. People move through hospitality roles quickly, which means the person who knows how to check equipment and what to do when something looks wrong may not be on shift when it matters.
Both problems point to training and simple rules rather than to more paperwork. New staff should know which equipment is checked, what a damaged lead looks like, and what to do with a faulty item — the answer being to remove it from use immediately and report it, not to tape it up and carry on. Putting that in the induction and reinforcing it at handover is far more effective than a folder nobody opens.
Hotels, motels and catering are not one workplace
A café, a hotel and a catering business all fall under hospitality, but their electrical profiles differ enough that a single template will not fit. A hotel or motel runs guest rooms alongside kitchens, laundries and plant rooms. Guest rooms bring kettles, irons, hairdryers, chargers and portable heaters that are used by people who will never read a safety notice, plus appliances that are moved and knocked about with no staff present. The laundry adds commercial washers and dryers drawing heavy current in a damp, hot room, and plant rooms hold pumps, boilers and controls that are genuinely installation-scale equipment rather than portable appliances.
Catering is different again. Equipment travels. Fridges, bain-maries, hot boxes and urns are loaded into vans, plugged into unfamiliar circuits at venues, and handled by a rotating crew. That movement is where the hidden damage accumulates — a lead bent the same way on every trip, a plug pulled out by the cable rather than the body. If you run off-site catering, treat the equipment that leaves the premises as its own risk group with its own checks, and make sure whoever sets up on site knows what a damaged lead looks like and what to do about it.
Record-keeping that actually helps a venue
WorkSafe recommends documenting results when equipment is tested or inspected and keeping the test results on site, whether on paper, a computer or a phone. In hospitality that usually means a register of the equipment, a schedule of what is checked and when, and a results log. Keep it somewhere a duty manager can find it quickly, because the moment you need it is usually the moment something has gone wrong at 7pm on a Friday.
A hospitality electrical safety checklist
- List every item plugged in across the kitchen, bar, front of house and back office.
- Note which items sit in wet, hot or greasy areas, and treat those as higher risk.
- Set and document inspection and testing intervals that reflect the kitchen environment.
- Check cords, plugs and casings for damage regularly — not only when a test is due.
- Confirm which areas have RCD protection and test the RCDs daily with the test button.
- Remove any faulty item from use immediately and have it repaired or replaced.
- Cover electrical safety in staff induction and at shift handover.
- Keep the register, schedule and results on site and easy to find.
Common mistakes in cafés, bars and hotels
- Running heaters, fryers or coffee machines off extension leads or power boards as a permanent fix. Extension leads are a temporary solution, not a long-term connection. Our guide to extension lead safety explains the risks here.
- Assuming a venue is safe because nothing has gone wrong yet.
- Treating a test tag as a licence to ignore a lead that is visibly damaged.
- Forgetting RCD protection in outdoor dining, sculleries and wash-down areas.
- Losing track of equipment because there is no register, so nobody knows what is due.
When to bring in a professional
A PCBU can train a worker and test in-house, and many small venues do exactly that. It becomes worth engaging a provider when you have multiple sites, when you cannot spare staff during service hours, when appliances are hard-wired or need a proper three-phase check, or when you want an independent record of what was done. Testing itself does not need a registered electrical worker, but any fault it uncovers must be repaired by one, so factor that into your plans.
