An employee and a coworker were working to move a stack of pipes. The coworker was operating a forklift and taking layers of bundled pipe from off the stack and moving it to another area. The employee was placing wood boards between the layers of pipe on the new stack being made. During this operation, the employee on the ground walked behind the taller stack of bundled pipes to recover some more wood for the next layer of pipe; at the same time, the coworker was using the forklift to pick up the next layer to be moved. One of the forks on the forklift knocked one of the bundles of pipe from the next lower layer, causing it to hit the employee in the arm and foot, causing a skin and muscle avulsion on his arm and crushing/amputating his foot.
