Well of course he shouldn't have raised his dump box!!! We have strict internal policies about working around overhead power lines. Unfortunately you can establish all the policies you want, train people over and over again and they still make poor decisions. And before anybody asks, yes we do have a disciplinary policy and yes everyone knows about it and yes we've disciplined employees regarding this topic before. But that wasn't really my question so lets see if we can get back to that . . . Since my original post I've learned that the 3 overhead lines carried a total of 13,200 volts so the line that arced to the truck was carrying 4,400V. Do any experts out there have a good idea what the arc-over distance would be for this situation when the relative humidity was 55%? I'm trying to investigate this incident and be as fair to all employees involved as I possibly can.
