Industry leading ventilation hygiene, system surveying and kitchen extract cleaning company, Ventilation Surveys and Services (VSS) Limited has recently undertaken a clean involving two vertical extract ducts, running from a basement level kitchen to the roof of a ten-storey building in Central London.
Access to the riser was only possible at floors 9, 7, 4 and 1, and abseiling down the risers was strictly prohibited by the landlord due to health and safety concerns. As a result, VSS was called upon to resolve the problem thanks to the company’s innovative approach to on-site problem solving and the specialist equipment that VSS uses.
A Lifa Hydmaster supplied by Hasman Technology Ltd was used to clean the risers via hydraulic rotary brushing with chemical delivery at the point of brushing.
As a direct result of the clean undertaken by VSS, grease levels have been reduced to below 50 microns on the surface of the duct, from readings in excess of 500 microns before the cleaning commenced. The site will now be using VSS to undertake 6 monthly scheduled visits to maintain the riser condition to levels below TR19 guidance of 200 microns.
Whether you are a systems designer, building owner or responsible for Health & Safety compliance within your company, you will need to ensure that you are completely familiar with the ductwork maintenance guidelines which apply to your industry. One call to VSS will help you to understand the regulatory requirements for your business.
