There is also the questionablity of Adjustable Spanners in Areas where if the spanner was to slip, it could fall into a busbar chamber.
I had a situation like that about 10 years ago, I'd laid Neoprene blankets+clips before the work started.
I was asked what all that rubbish was for?.
Got your washing there son?
And as it happened, a spanner did end up on the blankets. GRRRR
400V bus carrying 2400A would have been a nasty blast, considering that there were 5 of us working on the Main ACB.
You just can't teach some people.
