When it comes to any kind of work that goes on around high-voltage overhead power lines, the Maryland Occupational Safety and Health Law places safety responsibilities squarely on employers.
MOSH gives special emphasis to safety training, in that educating workers about safe work practices in proximity to power lines is essential.
Many accidents around energized power lines involve cranes, truck-mounted lifting equipment (bucket trucks), digging equipment and ladders. If these machines or objects come in contact with the lines, workers could suffer severe burns and other injuries, or instant electrocution.
Maryland law requires that workers and all their equipment stay a minimum of 10 feet away from overhead lines, with appropriate hazard signs. The minimum clearance for cranes is 20 feet. An operator should position the crane in such a way that the radius of the boom swing is outside of the absolute minimum clearance relative to the power lines.
