Helping safeguard emergency escape routes
Falling or hanging cables can pose a major safety hazard in the event of a building fire, a fact recognised by British Standards regulating wiring systems installed above escape routes. Figures show that there were 14 deaths from cable entrapment between 2004 and 2014; in a fire, falling cables can present a major risk to building occupants and firefighters.
Amendments to BS 7671:2008 of the Wiring Regulations (Amendment 3) require cabling above escape routes to be supported by fire-resistant fastenings and fixings to prevent collapse in extreme heat.
One of the easiest and quickest ways to achieve this is through the use of Firefly fire clips. The spring-loaded clips have been specifically developed to fit on the inside or outside of Marshall-Tufflex mini/maxi trunking and conduit, holding cables secure in the event of a fire, ensuring escape routes remain free and accessible should fire break out. The clips are fire resistant above 1,000°C for up to 120 minutes, far exceeding the requirements of 45 minutes at 930°C. Installation of Firefly clips satisfies fire regulations prohibiting the use of non-metallic clips or plastic trunking as the sole means of support for cables.
Firefly fire clips are the latest addition to cable management market-leader Marshall-Tufflex’s product range. They fix to walls and ceilings, are quick and easy to install and do not reduce the usable space for cables. The internal version fits within trunking prior to cable installation; the external version can be retrofitted. Firefly clips are also available in kits which include specifically designed, fully compliant fixings for either masonry or cavity walls that will also ensure that the wiring stays in place.
