Posted By Alan Barthrope Is anybody aware of any gudance for earthing scaffold/hoist structures? Scaffolds/hoists often stand on timber sole boards and may not have direct contact with the ground however they often touch the structure which may provide an earth route to the ground. The electrical part of the hoists sytems are earthed. When should you start to think about earthing either of these structures. Should it be specified in all cases. Any reference to guidance documents and/or a clarification of the general principles would be appreciated.

Posted By Alan Barthrope Thanks for that Ken. Can any body quote me what it says to save me purchasing the whole document? Any other comments will be greatfully recieved.
