Posted By Julie Watson Debbie I had this problrm, when I phoned the HSE they said for pallets it should be no more than 6 x the smallest width of the bottom pallet. Hope this helps a litttle Julie

Posted By Martin Taylor I must admit that this sounds quite a high stack for a pallet dimension of 1m x 1.2m this would make a 6m high stack. Considering the scaffold guideline of 3 x minimum base dimension 6 x seems dodgy for stability and especially for accuaracy of loading by fork truck. I don't have a figure myself and would be interested in other responses to this question - I have posted similar questions in the past with regards to stacking of stillages (metal boxes) but didn't get a great deal of response. This strikes me as a very common industrial situation and I would expect some form of standards to refer to. hope you get some more response - I'll keep an eye out thanks Martin
