Services that CANNOT be installed in an exit or paths of travel

Clause D2.7 of the National Construction Code ("NCC") outlines services that cannot be installed in an exit or the path of travel of exit. Reading through the list, it is obvious the writers are seeking to maintain the integrity of the exit and path of travel to a required exit by removing risks from the inception or spread of fire.
