SWA in coffee shop

Northern Spark

I need to run some SWA, surface mount on a wall in a coffee shop through two rooms, prep room and roasting room. I would think the rooms are part of the fire escape route. Do I need to use fire resistant fixings? If so, how many per metre to satisfy 'to prevent premature collapse'? As I might use them in addition to ordinary cleats. I can't seem to find an ACOP on this.

    On a different matter, in the same installation. The building(incorporating the coffee shop on the ground floor and short term let apartments above, with a common entrance), which is a listed building, has been recently refurbished, including re-wired. It looks like they have used LSNH cables for most circuits that I can see. Would this normally be a requirement in such an installation?

    Maybe not always a rigid legal requirement, but commonly a contractual spec from more switched on designers. PVC, which is the usual alternative to LS0H, is pretty horrible in a fire, releasing hydrochloric-acid gas and black smoke. Certainly LS0H is what you would expect to see in larger buildings to facilitate evacuation and minimize smoke inhalation casualties. Certainly mandated in underground stations, schools and hospitals, and a very good idea in other places where a fire evacuation might not be instantaneous.   Of course much of that good work is defeated if the expensive LS0H cables are then routed inside PVC trunking, but a few trunking manufacturers are catching up with Poly carbonate and similar offerings for those who don't want steel on show..
