COAL MINE FATALITY - On Thursday, May 4, 2006, a 40 year old contractor with 2 1/2 years of experience was electrocuted while clearing brush from the right-of-way of a 12,470 VAC transmission line. The miner touched a loose guy wire causing it to contact an energized conductor on the pole. There was no insulator, ground, or proper anchor at ground level preventing the guy wire from becoming energized.
Connect guy wires securely to the system ground, and/or properly install insulators to protect miners in the event of a breakage. Anchor guy wires where they will not be contacted by vehicles and equipment or be disturbed by maintenance personnel. Examine areas surrounding electrical installations for potential hazards before beginning any work, including trimming weeds and brush. Mark guy wire anchor points for easy identification.
