AMD2 - Clause 422.2 - Cables in protected escape routes.

I'm just concerned that if corridors become fire rated due to compartmentation then they become defacto protected escape routes and then the clause is triggered.

Appendix 13 explains more details. It does not seem too difficult to comply.

Non combustible conduit, such as steel conduit or trunking  is acceptable, as is bare M.I.C.C. cable. Expert fire safety advice may be required.

I read that as being only for the permitted circuits serving the installation within the protected route - lighting, emergency lighting, fire alarm, cleaner's socket.

The main concern as stated in Appendix. 13 is that of allowing a safe escape from a building in case of fire where escapees travel a longer distance  than normal. This may occur in large and more complex  buildings. The removal of flammable materials is a wise one. Flammable materials may cause toxic smoke and also restrict visibility.
