The hospitality and food industry in Lismore bounced back quickly following the flood of 2022. Kitchens were newly equipped, premises re-opened, and community-based food businesses started operating in the area once again. What the post-flood period often overlooked is the regular cleaning schedule of exhaust systems which could have either continued from before or started accumulating deposits within the first week of their operations.
Grease accumulation begins right away, and grease cleaning Lismore is essential from the outset. No matter if it is a new commercial kitchen or not, it doesn’t remain clean simply because its equipment is brand new. Baffle filters start collecting deposits, duct walls are accumulating a film, and fan blades gather deposits which keep compounding in each cooking session.
The Venues That Tend to Fall Behind
Restaurant establishments usually get it done because there is pressure to meet inspection and insurance criteria. But the venues which are most likely to lag on their cleaning schedule are the ones which do not see themselves as commercial kitchens in any way.
Community halls equipped with shared kitchen facilities, aged care centres which conduct low-volume cooking, school canteens, clubs which provide kitchen services during events but not daily services; all of these collect grease deposits in their exhaust systems which might go uncleaned for years. Even if the usage is infrequent, the risk is still present because the grease deposited during rare sessions of cooking carbonises and dries up with time which makes it more difficult to remove and reactive as a fuel in case of a flame.
Lismore City Council requires the certification of fire safety of applicable commercial premises once a year. This obligation encompasses all the fire safety requirements of such premises and holds true no matter how often the kitchen operates in reality. Since 13 February 2026, building owners of applicable Class 2 to 9 buildings in New South Wales will also have to comply with AS 1851-2012 regarding essential fire safety measures.
Where Grease Actually Builds Up?
The bits of the system that desperately need a pro to come in with the right kit, and can’t be done by the cleaning staff on their own:
- Horizontal duct runs, you know, where the grease just pools and solidifies at every low point, and refuses to budge.
- Duct bends and direction changes; these are perfect places for deposits to get stuck, even if the filters are squeaky clean.
- Fan housing interiors; grease on the spinning blades isn’t just a mess, it creates an imbalance that can also hike up the electricity bill.
- Rooftop discharge points; it’s a fire risk, and a potential breach of the rules under AS 1668.1, a real headache for building owners.
The AIRAH Best Practice Guide for Commercial Kitchen Exhaust Management first put out in 2022 takes a sensible view, saying you should figure out how often to clean by actually measuring the grease thickness in your system, rather than just sticking to some arbitrary calendar schedule. That’s the evidence-based approach, sitting alongside the basics in AS 1851, and it gives operators a solid defensible record to show for it.
What Operators in Lismore Need to Keep Handy?
The Annual Fire Safety Statement should have all the relevant fire safety work documented. Let’s be clear: building owners are on the hook for all this, as per the 2026 regulations; the lease agreement doesn’t change that. Leased operators need to know who’s going to be responsible for fire safety, before they even start an inspection.
An authorised technician’s cleaning certificate will give you the date, what work was done, and before-and-after measurements of the grease. That’s what fire assessors and council are going to want to see. Doing the cleaning right before submitting the statement is the way to go.
