BS 7671 - Regulation 422.2

Rob McConnell
I have a small problem that I would like to have some clarification on.
In principle  Regulation 422.2 requires that:
Cables or other electrical equipment shall not be installed in a protected escape route unless part of:
(i) an essential fire safety or related safety system
(ii) general needs lighting
(iii) socket-outlets provided for cleaning or maintenance.
I am currently designing an all electric building that consists of four storeys and has four escape stairs. one at each corner. The escape stairs are linked by corridors which form part of the designated escape routes.
The mechanical designer wants to heat the corridors and stairwells with electric panel heaters, but I have said this will not comply with Regulation 422.2, however the mechanical designer has said that heating has to be installed in these areas in order to comply with the Building Regulations.
I have spoken to other engineers and an NICEIC Inspector regarding this issue and we cannot come up with a definitive answer, and would value your opinion if possible

    There was some discussion earlier about "protected" escape routes - with some suggesting that they're they kind that are all bare concrete & steel types of area - and your normal carpeted corridor that also functions as an (ordinary) escape route is something different.

    Even if your routes are protected escape routes, I guess the requirements could be satisfied by some other kind of heating - e.g. radiators - even if the heat source is an electric boiler located elsewhere.
