Fundamentally, the principles of BS 5973 remain unchanged and there are very few changes in the day to day work of a scaffolder. It means that some of the requirements in BS EN 12811-1 were reconsidered in preference to good scaffolding practice. It was paramount that the HSE and NASC address each of these differences to decide on a strategy which would provide best practice for the safe erection, operation and dismantling of each scaffold. Structural design according to limit state theory. Reappraisal of effective lengths for the purpose of estimating the safe loads on standards. Wind loads on scaffolds shall conform to the national standard BS 6399. In the absence of wind, a scaffold shall have a notional horizontal load applied separately parallel and perpendicular to the bay. January 26th 2009 platform with 100% of the service load and one adjacent platform (above or below) with 50% of the service load. Reduction in the number of working platforms in use for light duty, general purpose and heavy-duty scaffolds. Loading according to “in-service” and “out-of-service” conditions. No differentiation between loading on main platform and inside boards.

Minimum unimpeded area along the full length of the working area. Seven width classes and two headroom classes. Six service Load Classes, some with partial area loads. The principal differences between the European Standard BS EN 12811-1 and BS 5973 are: Important that a document was prepared to give guidance to scaffolders and users alike, in the absence of BS 5973. The support of the HSEĪppropriately defining a safe method of working for the future. However withdrawn by the BSI because it was neither consistent nor compatible with BS EN 12811-1. TG20 is based on the previous UK scaffold standard BS 5973. TG20:08 has been issued as technical industry guidance on the use of the European Standard BS EN12811-1 and applies to all tube and fitting scaffolding from the most basic to the most complex of scaffold structures. New Scaffolding Guidance TG20:08 Guide to Good Practice for Scaffolding with Tube and Fittings The NASC (National Access and Scaffolding Confederation) has recently issued new guidance that will impact on all scaffold design in the UK. NATIONAL ACCESS & SCAFFOLDING CONFEDERATION The NASC is recognised as the national trade association for access and scaffolding in the UK.
