An employee was on a roof guiding insulated roof panels into place to secure them into steel beams with self-tapping bolts. He was working with two other employees who were in a scissor lift. The roof panel slipped from the beam at the peak before being secured and fell to the scissor lift below. This caused the other end of the lift to teeter upward, making contact with a 7,620-volt powerline. All three employees were shocked and received electrical burns. The employee on the roof fell approximately 25 feet to the concrete ground below. He was hospitalized with multiple breaks of the right leg and arm, numerous broken facial bones, severely damaged lungs, a tear in the aorta, and possible spinal damage.
