Good advice, even worse a line that may not at that moment be hot can be quickly energized without any apparent human intervention. Power company software is designed to send a current through a problem line at certain intervals to see if a transformer can be reset remotely or to confirm an open circuit issue.

Thus, a line which may have been "safe" a second ago, is suddenly energized now.
