Health & Safety is generally all common sense, i think a big part of why its gone so daft is because of the "Claim Culture" we now live in, all about passing the blame when things go wrong

Riggers not been banned yet, heard about it though because lack of ankle support and because they flare out on the top (imagine climbing a ladder and it snags underneath a rung)
however the riggers im wearing at the moment DO have ankle support
