S h o r i n g r e g u l a t i o n s a n d s t a n d a r d s 100 % The transposition of the new European directives into French law by the decree of 1 September 2004 has not led to the abrogation of article 218 relating to shoring towers in decree of 8 January 1965. For the time being, therefore, there are no explicit requirements for training, justification by calculation notes and inspecting shoring as set out in the decree of 1 September 2004 and the order of December 2004 for scaffolding. The decree of 8 January 1965 still applies for shoring. Decree of 8 January 1965 The design of shoring over 6 metres in height must be justified by a calculation note and the shoring must be constructed in accordance with an assembly drawing, except in emergencies or if it is not possible to comply with the drawing. The calculation notes and assembly drawing must be kept on the worksite (article 218). Regulations: Shoring towers assembled with prefabricated components: European standard NF EN 12813 replaced standard NF P93-550 of December 1987 but does not provide for an assessment of the compliance of shoring towers. That is why in 2011 the NF mark's ad hoc committee decided (see reference framework NF096) to continue referring to standard NF P93-550 of December 1987, pending publication of the future French standard NF P93-551. This standard will expand the European standard by: - defining a method for Eurocode calculations and relevant tests, - adding technical specifications related to the safe assembly and use of shoring towers Pending the publication of the new standard (NF P93-551), Mills scaffolding, in particular the Touréchaf, is fabricated according to the same standards and in the same production unit as “Mills Tour” equipment. France Health Insurance Agency Technical Note n° 24 This note applies to shoring towers and is intended to improve the safety of users. Extracts from the note Prevention of risks of falling from heights - The towers must be designed so that they can be assembled, dismantled and used safely. - It must be possible to adjust the heads and fit beams while standing on the top deck which should be constructed in such a way that there are no gaps in the deck and that the deck covers the whole area of the tower. Access should be through a hatch . NB: A risk assessment should be carried out before dispensing with toeboards while assembling, dismantling, using and adjusting scaffolding; subject to a compensatory measure such as using the non-slip circulation and work surface. - When the towers are assembled in bents, provide walkways with guardrails, if required, to pass from one tower to another . Prevention of risks of musculoskeletal injuries - Reduce the weight of elements and the number of constituent parts in the towers to the minimum. - Design the tower so that it can be moved easily by crane . Prevention of risks of tripping - Include a means of accessing the interior of the tower which can be used at each working level . - Improve the ease of access to the inside at the bottom of the tower. Prevention of sundry risks during handling - Provide integral mechanisms to lock the screw jacks at the bottom of the tower. - Attach locking pins and wedges to the components so that they cannot be lost . Equipment from different sources As for the scaffolding, all the equipment must be from the same source (see page 8). 01.11.17 T e c h n i c a l i n f o r m a t i o n
