I have a copy of the Construction (Working Places) Regs 1966 S.I.1966 No 94 which contains some references to Scaffolding: it includes, Handrails, Bracing interestingly it shows the continous Facebrace as I was taught, nothing new there.
Boarding, suspended scaffolds bosuns chairs, trestle scaffolds, but the bit I dislike says Simple Scaffolds cheeky Beggars nothing simple in this game.
