Posted By Paul Clarke-Scholes CMIOSH Can anyone tell me what Regulation 36 said, please? I'm trying to plan some work on a wood wool roof slab and the material has a data sheet saying it complies with these regs. OPSI publishes the 66 Safety Health and Welfare Regs [http://www.opsi.gov.uk/si/si1996/Uksi_19961592_en_1.htm in case anyone fancies being nostalgic, or is interested in the history of construction safety] and (strangely) I haven't kept any copies and yes they were in force when I started out in this business! Failing that; anyone remember what the safe working load was designed to be? Or knows about the propensity for the material to deteriorate?

Posted By peter gotch Paul Regulation 36 did not specify any loadings "liable to fracture if his weight were to be applied to it and so situated that if it were to be so fractured he would be liable to fall a distance of more than 6 feet 6 inches". HSE guidance on safety in roofwork comments that wood wool slabs often fragile e.g. if weakened by water damage. Fragility or otherwise will depend on centres between supports, thickness of slabs, amongst other things. Current test regime for non-fragile at http://www.roofworkadvic...k_-test_for_non_fra.html Regards, Peter
