Electricity

Workers are at risk of electrocution when using metal ladders around energized power lines. A NIOSH review identified over 154 electrocution deaths from contacting overhead power lines with portable ladders. These accidents usually occur during the erection, lowering, or relocation of the ladder. Also, a disproportionate number of deaths have occurred among Hispanic workers, which indicates a need for bilingual warning labels and training.

Workers should never use metal ladders around energized power lines or equipment. Fiberglass or plastic ladders are a safer option. Workers should keep conductive objects, such as metal ladders, at least 10 feet away from energized lines up to 50 kilovolts. For every additional 10 kilovolts, workers should maintain an extra 4 inches of clearance.

Employers are responsible for ensuring that the worksite is safe. If power lines are present near a worksite, the employer should contact the energy utility company for assistance. Workers need to be responsible for awareness of their surroundings, including looking up and being aware of any overhead power lines and reading the warning labels on their equipment.
