To help meet the requirements of the updated BS 7671 IET Wiring Regulations, Marshall-Tufflex has extended its range of Firefly fire clips. In the event of a fire the clips are designed to prevent cables falling and creating a hazard – providing a safer evacuation and allowing easy access for fire service crews.
The Firefly range now includes clips suitable for use on Marshall-Tufflex Maxi, Mono, Twin165, Twin Plus, Sterling Profile, Sterling Curve and Odyssey trunking systems. The clips fix to walls or ceilings and with a spring-loaded design are quick and easy to install. The Firefly fire clips are fire resistant above 1000°C for up to 120 minutes and feature rounded ends to prevent damage to cables and injury to installers, and the design optimizes the usable space within the trunking.
It is vitally important that cables are suitably protected from collapse and spill"
The range includes both internal versions that are fitted within the trunking prior to cable installation and externally fitted variants for a fast and simple retrofit. The previous IET Wiring Regulations required that all wiring on escape routes be protected from premature collapse during a fire. The 18th Edition of the regulations published in 2018 extends this requirement to the entire installation.
Fire safety regulations
Nick Hayler, Technical and Product QA Manager at Marshall-Tufflex has worked extensively with BEAMA on fire safety including chairing a committee on the issue of premature collapse. The committee aims to clarify the definition of ‘premature collapse’ and is in the process of drafting guidance for specifiers and installers to help achieve compliance.
“Falling or hanging cables present a serious risk in the event of a fire, not only during the evacuation of building occupants but also for the fire service crew entering the building,” Nick explained. “Due to the severely reduced visibility within a building, Firefighters will commonly use the walls to guide them when sweeping the building. As such it is vitally important that cables are suitably protected from collapse and spill. The new additions to the Firefly range make it easier for contractors to comply with the updated regulations and minimize the risk to life in the event of a fire.”
