I think, as hard as Darkwoods post sounds,he is 100% correct.
The industrial setting,is no place to learn by trial and error. It can be the "extra curricular" goings-on,that are separate to the job in hand,that can be the cause of incident.
That may be random oral or gaseous expulsions,parts of an automated process...it could even be the monthly visit to a restricted area,by the "rat-man",that can cause a sudden loss of balance/concentration etc.
It is the awareness of ALL the possible scenarios,that can be hard to teach,yet too risky to learn by near-miss.
I have commissioned and dismantled plenty of overhead cranes,mostly German marques,with many using open tram-way bus-bars.
They normally offer no more risk than 3ph leads across a workshop floor,or groups of switchgear next to a roller shutter where the pressure washer is used...
What should've could've would've happened,is secondary to the sad loss,of a young lad,and as a father to two lads,,my heart goes out entirely,to this gentleman.
