Abstract: At approximately 3:30 p.m. on January 13, 2006, Employee #1, a concrete laborer, was readying a portable lighting tower to move to another site. At approximately 1:00 a.m. that morning, the tower had been parked under a 24 ft 4-1/2 in. high overhead power line and left extended at about 25 ft, with the generator and the lights on. The 18-person concrete crew gathered before 5:00 a.m. and began pouring the first slab. They turned off the generator at approximately 6:00 a.m. At about 3:00 p.m. Employee #1 began preparing the light tower for transport. He started retracting the tower by loosening a setscrew on the mast that was used to keep the lights directed. When the mast was loosened, it rotated the tower. The two-light bar tree mounted at the top of the turret contacted the 7,500-volt overhead line. Employee #1 received an electric shock and died shortly afterwards.
