Abstract: At 8:00 a.m. on February 12, 2013 an employee was working with coworkers forming and installing a storm sewer runoff for a new round-about interchange. The employee was positioning a metal chute which was located on the back of a concrete truck, pouring a foundation for the storm sewer. The concrete truck was under a 24. 5 ft high, 7.2 kV power line, this was perpendicular to the truck. Approximately 100 ft to the south, an operator of a Caterpillar Excavator ( Model #328D) was moving stone near the 7.2 kV power lines. While the operator was moving the stones, one of the phases came down behind the excavator. The excavator elbow, between the dipper arm and the boom, had struck the line causing the line to break. As the line came down, it came into contact with the concrete truck, electrocuting and killing the employee.
