What is Section 12?
Those who supply cable to sub-surface locations on the London Underground will be familiar with the term Section 12. This is because, following the King’s Cross fire on the Underground in 1987, the Fire Precautions (Sub-Surface Railway Stations) Regulations 1989 – also known as the Section 12 regulations – were introduced. Many people were affected by the smoke and toxic fumes during the fire and the Section 12 regulations stipulate that everything – from display boards to electrical cables – must adhere to stringent safety standards. Cable in Section 12 locations must meet the requirements of LUL Standard 1-085, which details the fire safety performance of materials used on the London Underground. In particular, Section 3.3.3 of the Standard lists the flammability, flame spread and smoke emission requirements for cable. All cables undergo rigorous testing to comply with the regulations.
