The compliance hazard associated with regional kitchens is one that often goes unnoticed. Over time, it creeps quietly into existence in the extraction system over the cooking process line, developing without making any warning signs apparent in its development, meaning it could be months or years before anyone notices. In Inverell and the New England region, commercial kitchen exhausts are often cleaned either by general cleaning personnel or other companies who clean what they can reach but leave the remainder alone. The consequence is a difference between what operators think is done and what actually exists in the duct.
This is a problem far from trivial. Grease builds up in any duct that has not been maintained through regular grease cleaning Inverell and is one of the biggest and entirely preventable sources of fire hazards in food businesses.
What Inverell Food Operators Are Required to Do Under NSW Law?
Under the Food Act 2003 all food businesses operating within the Inverell Shire Local Government Area are required to be registered with Inverell Shire Council. Fines will be imposed for failure to notify the council about your food business. The Inverell Shire Council is responsible along with the NSW Food Authority for conducting food safety compliance activities for the region through regular inspections. These inspections ensure that premises comply with the Food Standards Code and the Food Act, including the state of maintenance of the kitchen.
The NSW Food Authority has indicated clearly that cafes, restaurants, and retail food establishments are routinely inspected by the local council officers and that these inspections include the state of maintenance of the premises.
The Fire Risk That Grows Silently Inside Every Working Kitchen
Fire and Rescue NSW’s restaurant fire safety guidance identifies food preparation establishments as workplaces at high risk from fire, with the most common fires involving unattended cooking, overheating of cooking oil or fat, and the ignition of fatty residues within rangehoods and ducting. The guidance specifically recommends routine cleaning and inspection of kitchen rangehoods, ducting, and grease fans as a core preventive measure.
The AIRAH Commercial Kitchen Exhaust Management Best Practice Guide (2022) describes how duct fires, fed by grease accumulation, can reach temperatures that transmit through the duct wall via radiant heat and ignite surrounding combustible materials, including structural timbers and ceiling cavities, without any direct flame contact. A fire that starts inside a duct can move through a building well before it is detected from the kitchen floor. For a regional kitchen where emergency response may take longer than in a metropolitan setting, the case for proactive maintenance is practical as much as it is regulatory.
The Full Scope of What Grease Cleaning Needs to Cover
A professional clean of an Inverell commercial kitchen’s extraction system includes all parts that come into contact with grease-laden air produced by cooking processes:
- Canopy and rangehood inner surfaces above the cooking line.
- Filter systems including baffle filters or mesh filters, where grease is removed rather than just wiped off.
- Drip trays and grease channels, where grease run-off is collected and needs to be degreased.
- Ducting from the filter onwards to the fan and exhaust point, where access panels are opened or installed to clean accessible sections.
- Fan housing and impeller, which are cleaned to allow free airflow and degreased of grease deposits.
- Discharge point and cowl at roof or wall level, where air can flow freely.
A cleaning service that only focuses on the hood’s visible parts and changes the filters ignores the most problematic parts.
How to Set a Cleaning Schedule That Reflects Actual Kitchen Use?
While a fixed schedule can be a basis for a cleaning program, it is not enough on its own to maintain safety. Two kitchens that clean on a quarterly basis might have very different amounts of grease accumulated based on the type of equipment in use, operating times, and kind of food being cooked.
According to the recommendations of the AIRAH 2022 Best Practice Guide, an evidence-based approach would mean measuring grease thickness at standard test points within the duct and establishing the date of the next clean based on it. A kitchen that runs deep fryers on a busy lunch and dinner time will need cleaning sooner than one that serves a light menu on lower volume.
Why Every Service Needs a Record?
When the exhaust system is registered in the Fire Safety Schedule of the building as a critical fire safety device, the NSW regulations demand that maintenance records need to be kept for at least 7 years and provided in the Annual Fire Safety Statement. The AIRAH 2022 guide recommends that every professional cleaning service produces a verification report on the work done, findings, measurements of grease thickness and a deficiency list.
