Abstract: On December 20, 2012, Employee #1, with Unico Mechanical Corporation, was rotating a three ton, 40 ft by 33 in. by 12 in., nominal, I-Beam. The I-Beam was on its side. Employee #1, working with a coworker, wanted to rotate the I-Beam to the "up" position until it rested on the bottom flange. They were using a Crane (25 ton/10 ton Overhead; Bridge). The load was rigged with four chains terminated with standard lifting hooks. After the beam was set on its flange end, the chains were retracted and possibly caught on the bottom flange which tipped the beam over. The beam fell and struck Employee #1 on the legs. Employee #1 was taken to the hospital with fractures in both legs. Neither Employee #1, nor his coworker, had been adequately trained to rig or lift loads of the size and configuration of the I-Beam.
