ADCAS (the Association of Ductwork Control Contractors and Allied Services) has launched a free publication that explains some complex guidance on ductwork cleaning and access doors.

The ADCAS Guide to Ductwork Cleaning Requirements and Access Doors examines the current legislation and standards, and gives a clear insight on how contractors can apply these in their professional practice. It also looks at the content of: DW/144 Second Edition (2013), TR/19 Second Edition (2013) and BS EN 15780 (2011).

It explains the similarities and differences between these documents and offers practical recommendations for ductwork contractors, system designers and cleaning contractors to help them work with all three publications.

The Guide has been a joint effort by ADCAS members who have worked together to offer practical advice on cleaning access, duct cleanliness and access doors. It is a well-established fact that ductwork air systems can be a source of spreading disease and infections. With greater understanding of these issues, the requirements for access into the ductwork systems for maintenance, inspection and cleaning have increased.

This new publication therefore provides guidance on the cleanliness requirements for both existing and new ductworks. It also looks at the location and size of access doors and the cleaning and maintenance of ventilation systems which are very closely linked.

It is aimed at ductwork installers and also those responsible for the long-term maintenance of ductwork. The guide covers important issues, including information on how to deliver, protect and install new ductwork, location of access doors and access into large ductwork for cleaning.

In addition, it includes a pre-contract checklist that helps industry professionals to establish the requirements for each system from the outset, prior to a contract being awarded and started on site. Industry professionals will also benefit from the section on frequently asked questions.

Available free, the publication can be downloaded from the ADCAS website at www.adcas.co.uk.
