Government body to intervene on smoke damper issue – © iStock
A standards body has said it will act to address the continued controversy surrounding the installation of smoke control dampers in buildings.
The Office for Product Safety & Standards (OPSS) made its pledge following a series of meetings with the Building Engineering Services Association (BESA) which had issued several urgent warnings about this “potential Achilles’ heel” in fire safety strategies for buildings.
As the UK’s product regulator, the OPSS is responsible for the regulation of most consumer goods and construction products. Its aim is to guarantee that they meet their required performance to enable safer, better buildings across the UK.
The body said it was responding to potential problems that had been brought to its attention by BESA and was now carrying out a documentation review.
It announced: “Some manufacturers, importers, or distributors of smoke control dampers are being contacted to provide documentation which includes but is not limited to, declarations of performance.
“OPSS aims to provide targeted, risk-based and proportionate enforcement of construction products regulations and will act fairly and firmly where product risks exist.”
Technical bulletin
BESA produced a technical bulletin (VH001) to address concerns about the way many smoke control dampers and fire dampers were being installed ahead of a full update of its industry guidance for the ‘Installation of Fire Dampers and Smoke Dampers’ (DW145) which is due to be released later this year.
The bulletin was published after several BESA members reported finding that a significant number of dampers had been incorrectly installed and, therefore, were unlikely to perform their function of reducing the spread of smoke in a building during a fire.
DW145 makes it clear that contractors must follow the manufacturer’s instructions to ensure that fire dampers and smoke dampers are installed correctly and comply with fire regulations. However, the association’s technical director Graeme Fox said those instructions were often confusing.
He said: “For example, some clearly state that you should not use self-drilling, non-fusible fixings, but some are not so clear. We briefed the OPSS about this problem and they have now informed us that they are contacting manufacturers and importers to ensure there is clarity and consistency in their declarations of performance.”
Fox added: “We are able to communicate the risks and solutions via our technical guidance, but the intervention of the OPSS is hugely significant and means the whole supply chain, including clients, will now be on full alert and unable to ignore the problem."
The BESA bulletin also clarifies guidance and statutory requirements covering installation, testing, and maintenance of fire dampers and smoke dampers including clients’ legal obligations to ensure their fire safety systems remain fit for purpose in line with the Regulatory Reform (Fire Safety) Order 2005 for England and Wales and the Fire Safety (Scotland) Regulations 2006.
It outlines the crucial role played by the penetration seal in ensuring the overall fire-stopping integrity of an installation, the importance of maintenance teams being able to find and access dampers for testing and repair, and the need for designers and installers to seek expert advice from damper manufacturers.
