Description:A 21 year old male concrete worker was electrocuted at a precast concrete manufacturing facility when he climbed a steel column, stepped onto a steam pipe, and grabbed one phase of an energized three phase, 440 volt conductor that supplied electrical power to a wall crane. The employer was a manufacturer of precast concrete structures. On the day of the incident, the victim and two coworkers had just completed the form work for a box culvert. The victim and a coworker discussed moving the box culvert to the next work area. As the victim moved the overhead crane to assist in the move, two hoist cables became tangled around an I-beam supporting the runway of the wall crane. The victim dislodged one chain but then climbed a steel support column to free the other by hand. He stepped onto a steam pipe about 16 feet above the ground. He apparently reached out and grabbed the energized conductor. The current passed through the victim to the steel column
he screamed, and then fell to the ground. The cause of death was electrocution. It is recommended that crane runway conductors be guarded to reduce the likelihood of contact
that warning signs be affixed
that workers follow crane manufacturer recommendations regarding the operation of overhead cranes
and that a comprehensive safety program be developed and implemented.
