February 7, 20242 yr comment_41112 Do service riser cupboards/shafts in residential buildings require fire stopping at both ceiling and floor? Report
February 7, 20242 yr comment_41124 No - Approved Document B allows these to be treated as a protected shaft where the walls and doors to the sides need to be fire resistant, but the shaft can be open all the way up. Far too many risk assessors have wasted considerable amounts of client money on unnecessary floor stopping -it's not cheap and for retrospective installs quite difficult too. Report

I fully agree. But it seems to be a trend now. So many local authorities think it’s the right thing to do now, based on their interpretation of general compartmentation advice. While the too many Fire safety/Firestopping companies that probably know better, say nothing because they like the work. Report
