[Petrochemicals]

Yes of course the path available to make a circuit is the most important factor. Wearing trainers and standing on a wooden pallet I once accidently brushed against the anode(plate) cap of a valve(vacuum tube) at ~ 2kv with my hand. I felt absolutely nothing but I heard a faint crackling sound. The psu in question was capable of a good 5amps. As regard lightning strikes some people will survive a direct hit but most will not and those that survive are rarely the same again with multiple problems. A lot of cases involve a direct hit in the vicinity which can still induce catastrophic currents in an individual but way less than a direct hit.

Exactamon, I wonder what current flows for example when I touch a lighting cable, as the rcd didn't trip it cannot be above the 35 ma given that I am electrically insulated, one of the reasons that you are not supposed to earth aluminium ladders.
