Guess that's a grey area for consideration- if the designer has left an open space on a staircase without a prefabricated handrail ready to install from a " safe place" ie the ground, then the hand rail to go in, whilst not pre-fab', isn't on a scaffold platform form so probably can't come within the reg's i mentioned and the pc can ask for building regs height- but there's arguably design flaws depending on circumstances, and i think this discussion was started on the handrail on a scaffold ( again site H&S needs to sort himself) in my humble.....lol- Jakdan, don't know if you were asking me or slav there but i were 3pts off the distinction at certificate and the Diploma's going great cheers
