EVHA Guides to Good Practice

The Guides to Good Practice are a valuable resource for duct cleaning specialists and for their customers and other stakeholders such as government, insurers, landlords and employees - to help them understand what needs doing, and how it should be done

Cleaning & Risk Management of Grease Extract Systems

Grease extract systems are integral items of equipment which are found in most commercial kitchens.

 

This good practice document sets out to provide guidance and information that will be necessary when implementing grease extract system maintenance programmes and fire risk management strategies, in relation to grease extract systems.

Insurers are the most important stakeholder pushing for improvements to kitchen extract ventilation cleaning but landlords, neighbours and employees are increasingly concerned.


An appropriately maintained and monitored grease extract system provides the following benefits:

  • Reduces the risk of grease extract system fire

  • Reduces the risk of the spread of fires through kitchen ventilation ducts

  • Contributes to providing a safe and hygienic area, in which to prepare food

  • Provides a safer and more comfortable environment, for kitchen staff

  • Maintains the system operation in accordance with the original design.

Cleaning & Hygienic Management of Ventilation Systems

Ducted heating ventilation and air conditioning systems (HVAC) provide the 'lungs' of many modern buildings, carrying air to every occupant of the building.

Increasingly, Mechanical Ventilation with Heat Recovery (MVHR) systems use ductwork to recycle the heat in residential indoor air.

No filter is absolute and inevitably dirt accumulates within the ventilation ducts, which are usually 'out of sight and out of mind'. A dirty system cannot supply clean air and a fouled system provides mechanical, and ultimately fire, risks

The European-wide Workplace (Health, Safety and Welfare) Regulations therefore demand that "Mechanical ventilation systems (including air-conditioning systems) should be regularly and adequately cleaned. They should also be properly tested and maintained to ensure that they are kept clean and free from anything which may contaminate the air"

An appropriately maintained and monitored ventilation system provides the following benefits:

  • Reduces the risk of contamination of the air

  • Reduces the risk of adverse microbiogical growth

  • Contributes to the health, safety and wellbeing of occupants

  • Is part of a well maintained, productive work environment

  • Minimises the possibility of Sick Building Syndrome associated with poor ventilation

  • Improves mechanical efficiency and reduces energy consumption

  • Increases the lifespan and aesthetics of building fabric
