Installation Guides New SmokeShield Installation Guide With the publication of the revised Approved Document B (ADB) on Fire safety, the guidance on the use of fire dampers in ventilation ducts to protect fire compartmentation is now much clearer. It states requirements for dampers to have ES classifications to protect escape routes and areas with sleeping risk and that generally dampers should have a minimum E classification for general areas and run out ducting. To coincide with this Actionair has produced a new SmokeShield (and HotShield) installation guide. It presents an introduction explaining what changes have occurred and a summary of the presently tested installation methods giving the E and ES classifications. This is followed by an explanation section on the background to the ADB changes and the relevant standards. This is followed by a full two page description and drawing of each method. Finally there is an appendix, which shows some of the installation methods in terms of a storyboard with photographs. Each of the sections/methods/storyboards are available as a download from the website, as is the entire document (just follow the INSTALLATIONS link). Hard copies are also available for you to keep as a reference on your shelf. It is strongly suggested that deviations from the methods given are discussed with Building Control before use, if the requirements for E and ES classifications exist. They should be able to make a judgment that the proposed method is close enough to that tested to be able to approve it. It is still possible to use dampers tested to BS476 for installations where the fan will be turned off in the case of a fire or smoke incident. All the existing methods for installations meeting the requirements for BS476 are still available on the website. Documents are available in PDF format allowing you to download.
