Your Cooperative has to account for not only lines in the air but also when the lines come down as a result of wind or ice damage. Once lines are down, Line workers have to hook onto them and pull them back into the air. Many times this requires Linemen to walk through, ditches, revenes, and wooded areas. Trees and brush under and adjacent to the power lines can be very dangerous for Line workers and other utility personnel to work around. Trees and brush can also hide downed power lines that may be energized and could kill Line workers, members of the public or livestock. It is important that the power line corridor is free from all obstacles.
