i had metal framed bench which had sockets installed on them and there was cables running over the metal work and had electrical equiptment all over the benches so i supplementry bondes the benches to the socket circuits.
now this may not be a reg but its on my head if the frame become live and didnt opperate the circuit breaker.
so my advice would be dont look for regs etc its up to you use your experience to tell you what is safe or not, and weather you will be able to sleep at night.
Thats not bonding though....it's earthing.
