Ventilation update welcomed
15 August 2014
Gary Nicholls, MD of Swiftclean Building Services, and a member of the Building and Engineering Services Association (B&ES) Steering Committee responsible for TR/19, has welcomed its recently unveiled changes.
The new TR/19 (Second Edition 2013) guidance document: Internal Cleanliness of Ventilation Systems, brings TR/19 in line with both BSEN:15780, which was published in November 2011, and BSRIA’s BG49/2013 Commissioning of Air Systems guidance document.
Nicholls said: "We now have a framework which classifies ventilation ductwork systems according to their use and sets out clearly the standard of cleanliness which they must meet at the start of their working life. For the first time TR/19 spells out the requirement to hand over a ventilation system in a clean condition prior to commissioning.
"This is essential as in the past we have seen too many systems which evidently had too much mileage on the clock in terms of hygiene from the outset; something we would not accept in any more visible part of a building."
