An employee was performing a pipe count while a pipeline contractor was unloading steel pipe at a staging yard. The contractor was preparing to set a pipe segment (12 diameter) on the top row of a pyramid-shaped stack using an excavator. The contractor was making his final adjustments before setting the pipe when the injured employee (Enbridge Inspector) went to get label information from one of the pipes in the stack. The pipe stack shifted as the contractor began to position the pipe, and the bottom piece (42 feet long and 2,083 pounds) rolled onto the injured employee s lower left leg, trapping the employee underneath it. The employee was hospitalized with a compound fracture of his tibia and fibula and he required surgery.
