Abstract: At approximately 9:15 a.m. on January 31, 2003, Employee #1, a Signal Technician, was working alone in a bucket truck. He parked his vehicle (2001 Ford F350/6Z44987) curbside. There were three lanes of traffic in both directions. He placed one traffic cone at the left rear of his vehicle in preparation of blocking out a street sign. He did not place the cone directly into the traffic lane. Employee #1 was standing in the bucket, positioned 16 feet above and over the Number 3 traffic lane. A passing truck in the Number 3 lane struck the lower portion of the elevated bucket. Employee #1 was pushed upward and struck his head on the horizontal pole that was suspending the traffic signal lights. The impact between the truck and the bucket caused the bucket to bend and tip sideways, ejecting Employee #1 onto the pavement below. He was wearing a 5-point harness and his lanyard was hooked onto the bucket, but he was not attached to the lanyard. He suffered a concussion, fractured ribs and a broken collar bone. He was hospitalized for treatment.
