Wrexham Mineral Cables (WMC), a leading UK cable manufacturer, is calling for the establishment of a new fire-resistant cable standard to improve building safety and potentially save lives.<\/p>\n
WMC\u2019s call to action comes as the industry reflects on the 1,700-page Grenfell Inquiry report, which sets out how \u2018decades of failure\u2019 across government and the construction sector led to Grenfell Tower becoming a site of tragic loss of life.<\/p>\n
The report makes 58 recommendations, including the establishment of a new construction regulator responsible for developing suitable methods for testing fire resistance in materials and products used in construction.<\/p>\n
WMC says the industry reform must include a new standard that enables architects and specifiers to identify true fire survival cables, which are proven to perform to safety standards in real-world scenarios. The company warns the current regulatory framework allows for inferior cables to be used in safety-critical applications, putting lives and property at risk.<\/p>\n
Currently, specifiers are presented with a choice between polymeric \u2018soft skin\u2019 cables and mineral insulated copper clad (MICC) cables. Due to the existing testing regime, both cable types are classed as fire-resistant, creating a misleading impression of equivalence. However, MICC cables have consistently demonstrated superior performance and are proven to perform to measurably higher safety standards in ‘real fire\u2019 scenarios.<\/p>\n
Colin Hughes, Group Manager at WMC, explains: \u201cFire-resistant cables are integral to maintaining a building\u2019s critical electrical systems during a fire. For example, emergency lighting, sprinkler systems, emergency generators, smoke dampers and shutters, and fire alarms. If these systems fail, the consequences can be catastrophic.<\/p>\n
\u201cCurrent testing standards create an unclear picture of cable performance; they treat polymeric and MICC cables as equivalent, despite their vastly different fire-survival capabilities. It\u2019s all too easy for manufacturers to claim that products meet a required standard, even though the test methods themselves are not representative of \u2018true fire\u2019 scenarios.<\/p>\n
\u201cAs the Grenfell report has made clear, everyone involved in construction is responsible for keeping people safe. However, architects and specifiers must be equipped to make informed choices. We need a new standard that allows specifiers to identify true fire survival cables – and potentially help save lives.\u201d<\/p>\n
WMC has long advocated for stricter testing standards and better fire-resistant cable specifications. In 2023, WMC published a white paper outlining how cables directly impact building safety. The paper advocates for the introduction of a higher classification of fire survival cable, which can continue to power critical circuits in the event of a fire.<\/p>\n
Colin Hughes adds: \u201cLast year, the UK Government introduced stricter building regulations in England as part of new secondary legislation to implement the Building Safety Act. Unfortunately, recent events in London, such as fires at a residential block in Dagenham and at the historic Somerset House, serve as reminders that buildings of all types remain at a high risk of fire.<\/p>\n
\u201cThis is why we continue to call on the government and industry to take action and improve building safety with the introduction of a new standard that subjects all fire-resistant cables, regardless of size or construction, to true fire scenario tests.\u201d<\/p>\n
