Power Line Safety Fact Sheet
• Work at a Safe Distance. A safe working distance depends on the voltage of the power lines. Always maintain a distance of at least 10 feet from overhead lines and more than 10 feet if the voltage to ground is over 50 kilovolts (50,000 volts). The higher the voltage, the greater the distance that is needed between the lines and the workers. (See
