Mxslick,
I think to a degree what could cause problems here is nothing short of bad communication.
We use Shorting and Earthing (Grounding) of Overhead LV,MV and HV lines here, during maintenance work as part of our Health and Safety practice, it's been like that for years here.
If some idiot was to throw the controlling switch(which would never happen here, it's controlled by the PoCo Control room).
Other side of the coin, make sure that you only use a multi-person lock on your gear.
