System Cleaning

To comply with the Regulatory Reform (Fire Safety) Order 2005, grease extract systems must be inspected, tested and cleaned regularly to ensure the mitigation of fire hazards. In addition, advice and guidance provided by the Health & Safety Executive (HSE), BSRIA and RISC Authority, stipulate that kitchen extract systems should be kept clean to minimise fire and health and safety risks.

This is to be carried out by a specialist cleaning contractor (ideally registered on the BESCA VHE Scheme) fully in compliance with BESA Specification TR19® Grease

This system cleaning is essential to ensure correct system performance and remove any residual fire hazards. It is widespread practice for pictures of the internal faces of the ductwork and system components be submitted post clean to show that all grease and debris have been removed. A build-up of grease on the fan guards, impellor and casing will detract from the systems performance; if left in such a state for extended time periods will result in damage to the fan motor.

The canopy and grease separator plenum are areas with an elevated risk of fire. Consideration should be given to more frequent cleaning in accordance with the building insurers requirements.

Daily / weekly inspection and cleaning should also be implemented on canopies, separator panels, drainage channels and grease collection drawers. This would typically be carried out by the operator, due to frequency of requirement, fully in accordance with all relevant risk assessments and safe systems of work.
