SAFETENG,
This isn't the first time that I've heard of a death caused by this methode.
A plate measuring 2 ft x 4 ft you'd think should be bonded to something or grounded.
In that case, the utility found, an electrical current traveled through the cover because of a short circuit caused by the erosion of insulation protecting power lines. Such insulation can be worn away by wet weather and rock salt used to clear streets of snow and ice.
I was always under the impression that a short circuit was cleared in a matter of seconds.
Anything else is negligent, especially where exposed live parts are concerned.
One more un-necessary death!.
