While I understand the requirements surrounding individual oxy and acteylene cylinders and the requirement to store seperately 3 meters secured cages etc , outside the building . What about when the oxy - acetylene rig is set up i.e flash backs in place hoses etc etc ?We store them upright on trolleys and chained each night outside the building but the cylinders are still together . It is not practical to dismantle the sets every day to store the cylinders seperately at that stage and set it all up again before each use . My question is really behind our reasoning for storing seperately initially but not when its a working rig ? What are your views and does anyone have any practical ideas or comments on this ? P.s this has come from a client audit surrounding the storage of set up welding rigs ?

Thanks Jake , Im posting from australia so no real clear guidance here related to it . Thanks for the HSG reference which is in fairness , generally some of the best in my experience .
