Poor hygiene levels in ventilation systems can not only affect the occupants in the building, but can greatly effect the energy and efficiency of the system. Often ductwork is hidden from view and therefore dirt, dust and blockages will be hidden (out of sight, out of mind). If left this contamination may propagate unwanted allergens or provide a breeding ground for bacteria and moulds. This can seriously effect staff productivity and pose a health risk to visitors and customers.
The Workplace (Health, Safety & Welfare) Regulations require building owners and managers to ensure that mechanical ventilation systems (including air conditioning systems) should be regularly and properly cleaned, tested and maintained to ensure that they are kept clean and free from anything which may contaminate the air.

Most catering establishments feature a canopy extraction system in 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 and build up, 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. There should be a scheduled frequency of cleaning dependant on the number of hours per day the kitchen is operational.

Quality Environmental Services can undertake the clean and chlorination of all forms of water storage tanks, ranging from a small one piece polypropylene storage tanks through larger sectional vessels to underground reservoirs.

HSE ACOP L8 recommends annual internal inspection of domestic hot water calorifiers (para 182, c.);Draining the calorifier and checking for debris in the base of the vessel. The calorifier should then be cleaned if considered necessary.
