Hi, 

Please could someone give me a steer on guidance to use for fire safety in mix occupancy (shop / office on ground floor and residential flat on first floor).

Not purpose built - was a 1900's dwelling converted approximately 1950's.

I've been looking at LACORS and DCLG/HM Guidance for sleeping accommodation - is there anything else?

Due to the fire separation between the commercial unit (Hairdressers) and first floor being uncertain, I wanted a guide to show what compensatory features we could use, in particular early warning, linking in to flat.  But didn't know if Heat detectors in ground floor were permitted to prevent false alarms in the flat due to hairsprays and steam setting of smoke heads!

Any guidance / steer as to what guides to use would be much appreciated.

I am not aware of any guidance to assist you but you could use the purpose built guide which has this problem highlighted and apply it with your fire risk head fixed on.

Okay, thanks Tom.
