Investigation Summary

At approximately 1:00 p.m. on September 8, 2015, an employee was installing electrical conduit at the ceiling level to supply power to outdoor lighting. The employee was driving an electric powered scissor lift stocked with EMT conduit and electrical construction materials. The employee was operating the scissor lift near floor holes in the concrete left open for plumbing installation that was recently completed. The scissor lift was extended and it is likely that the vehicle was being repositioned when at least one of its wheels entered a floor hole causing the extended lift to tilt over and fall to one side. It appears that the employee stayed on the work platform for all or most of the time that the lift was falling to the ground and then struck his head against the concrete surface close to where the lift's platform struck the surface. The employee fractured skull and suffered other trauma to the upper body associated with the impact against a hard, cured, concrete surface and was killed.
