How about the issue of receptions in single staircase buildings (esp on the G floor)?
I accept it is dependant on a number of variables and has been accepted in fire certs (with restrictions) in the past when reception consisted of a desk, a bakelite phone and a diary. The only combustible item being the can of hairspray in receptionist's handbag.
But a modern reception area may well have two PCs, and air con unit and a fair amount of paperwork.
I accept that the type of AFD should be considered as a control measure and that for most buildings, receptions are rarely left unmanned, but where should one draw the line as the issue is surely preventing smoke in the 1st place, rather than informing occupiers of the presence of smoke in the stairwell?
