SteveNeedsAnswers Posted January 7 Report Posted January 7 A two-foot square timber fronted riser cupboard on a stairwell of a 5-storey residential block of flats contains three waste pipes and three electric supply cables running up through all floors. The hinges are not fire-rated, the door is 18mm thick with 10mm stops. No combined seals. Is there a need to better protect the escape route? Quote

AnthonyB Posted Monday at 20:14 Report Posted Monday at 20:14 Strictly speaking yes, but if at no point in the riser there are no meters, DNO fuses or distribution boards or anything liable to be an ignition source then you could make a case for tolerating it. Is it an open shaft or just with holes punched through floorboards or pipes & cables? Quote
