Abstract: At approximately 11:15 a.m. on November 16, 2010, Employee #1 was operating a truck mounted LLDH foundation driller Serial number 889, Company Number R-88. Employee #1 was drilling a 42-inch diameter pilot hole to a depth of 14 feet. Employee #1 removed the drill auger from the pilot hole and rotated it to the side, spinning off the material from the auger blades. Then, he moved the auger bit back over the pilot hole. The LLDH drilling rig separated from the truck chassis, and the 62 feet 6 inch tower boom fell toward the operator seat, crushing Employee #1. Coworkers reported hearing a loud cracking noise; the boom then swayed and fell, pinning Employee #1 to the ground. Authorities arrived on the scene with in approximately ten minutes finding Employee #1 crushed by the drill rig. Employee # 1 was killed.
