Cement finisher electrocuted in Ohio, February 25, 1988.
NIOSH 1988 Sep; :105
The case of a 42 year old male cement finisher who was electrocuted when the metal handle of a cement finishing bull float he was using contacted a 13.8 kilovolt power line was examined. The victim was employed for the past 7 months by a general construction contractor. The company had a written safety policy and safety programs with on the job training. The construction company was to build a hospital parking garage in a metropolitan area and asked the local utility to insulate three phase 13.8 kilovolt power lines in the vicinity of the construction site as a crane would be required. The utility insulated only the line nearest to the structure, considered to be the line most likely to be contacted. On the day of the accident the victim was using an aluminum bull float to finish concrete placed for the floor of the fifth level on the power line side of the building. The handle of the bull float consisted of two 10 foot sections of aluminum pipe. When the victim was pulling the float toward him the aluminum handle contacted one of the uninsulated power lines. He then fell 55 feet to the sidewalk. Recommendations included that the company should have reviewed the situation for additional hazards during the job. Had this been done it would have been noted that the handles on the bull float could extend beyond the insulated line and contact the uninsulated lines. The electric company should have routinely covered all three lines. Tool handles should be made of nonconductive materials such as fiberglass.
