Kitchen extract cleaning

Do you have access doors in your ductwork?

The majority of catering establishments feature a canopy extraction system within the kitchen to control the build up of heat, steam and grease emissions in the cooking area.

The filters in the canopy act as a good “first line of defence” against grease deposition but still allow the smaller particles to pass into the extract ductwork system. These deposits will accumulate over time and can pose hygiene and fire risks. Whist the canopies and filters are easily accessible for regular cleaning by catering staff the ductwork is normally hidden above a ceiling and can pass through numerous walls and floors before reaching the discharge point. These hidden sections require specialist attention for cleaning to TR19 standard. This standard also indicates a recommended frequency of cleaning dependant on the number of hours per day the kitchen is operational. Once cleaned to TR19 a cleaning certificate can be produced to verify compliance with Health & Safety obligations & Insurance requirements.

Many hotels, restaurants, leisure clubs and fast food operations now include the kitchen extract system on their regular maintenance schedule. Apart from hygiene and continued business considerations there are potential legal implications to consider. If for example fire investigators found that there were no access doors in the ductwork, making it impossible to clean, then the building owner could be guilty of negligence and face prosecution under the Health & Safety (Offences) Act 2009.

Case history


South_Coast_CollegeAn impressive adult education college that offers a wide range of residential courses such as sculpture, wood working and creative writing has a very active catering department. The two restaurant facilities on site serve the needs of residential students and visitors offering a varied menu of hot and cold meals. Both locations have a canopy extract system which require periodic maintenance to prevent the build up of grease which can constitute a fire risk. Upon successful cleaning of the two canopy extract systems the Buildings Manager at the college commented as follows “ We were concerned that it would be difficult to get all of the extract systems cleaned in one visit. The necessary labour was resourced to fit into our busy schedule who worked extremely efficiently whilst on our premises.”
