CABLES IN PROTECTED ESCAPE ROUTES

John Peckham

Thinking about the the thread on metering for flats.

The DPC for Amendment 2 in 422.2 only allows cables supplying safety services, lighting and sockets for cleaning to be installed in a protected escape route.

I am thinking that it is usual for supplies to flats, in blocks of flats, to be run from a riser cupboard down the corridors and enter each flat above a demountable ceiling. 

So post AMD 2 how would the supplies to flats from a riser be practically installed. There is only minimal clearance from the demountable ceiling to the soffit , it would be difficult to enclose the cables in  Durasteel fire cladding. Lowering the ceiling is not a usual option.

    The answer then is that the ceiling has to be fire rated for the same duration as the walls. That's how it's regularly done in Firefighting Lobbies and Shafts.

    And as Mike has highlighted, it's already a requirement of part B so it is mandatory now. We shouldn't wait for AMD 2….
