Posted By Frank Hallett Good morning Carl There is a presumption that you've attempted to work through the heirarchy of the WaH Regs but remain confused - along with loads of others - about how to apply the requirements to your specific workplace and activities. The fact that it's a fabrication facility indicates that it should be a fairly well-controlled environment and therefore the ability to provide easily managed fixed and temporary solutions to working at height should be relatively easy to implement. I recognise that as the work in hand grows in size or changes in shape that there will be a need for operatives to often change their position [and posture - don't foget MH & ergonomics] often several times during the fabrication process and that this will present some serious challeges. There are no simple answers to your question as we have no specific knowledge of your particular layout, activities, etc; all of which are essential to providing anything other than general advice and guidance. If you still need more support, as I suspect you will, either provide a great deal more info on this Forum or, preferably, get direct professional advice; although this will cost, it's better than not getting it right.
