Amendment 3 of BS 7671: 2015 was introduced on recommendation of home secretary Eric Pickles under Coroner’s Rule 43 – Aim to Prevent Deaths, following the deaths of firemen by entrapment, both in Southampton and Stevenage.
It covers the replacement of inadequate Fuseboards but it also has a lesser known Clause covering the support of overhead wiring systems in the event of fire with metal clips.
The publication of Amendment 3 to the 17th Edition (BS 7671: 2015) Wiring Regulations states that after 1st July 2015 “Wiring systems in escape routes shall be supported in such a way that they will not be liable to premature collapse in the event of ﬁre.” In other words by using fire-resistant metal supports for trunking and conduit.
It is because of the deaths in Stevenage and Southampton that Firefly Fixings Ltd took on designing and manufacturing compliant cable clips that could withstand immense heat for a prolonged period, to allow safe passage from a fire and to prevent entrapment in falling wires.
Metal wiring supports everywhere.
