Abstract: At approximately 11:30 a.m. on August 22, 2002, Employee #1 and a coworker, both iron workers, were loading 35 ft long I-beams onto a trailer. Employee #1 was on the end of the trailer closest to the lift operator and was acting as a signalman, while the coworker was on the other end. They had loaded several beams that morning and had just unhooked the slings on another beam when Employee #1 gave the lift operator the signal to hoist the slings. As the slings went up, the hook became caught on the edge of the beam and it started to roll. Employee #1 and the coworker both jumped approximately 6 ft to the ground to avoid the falling beam. The coworker was able to jump clear, but the beam struck Employee #1, who suffered a fractured right leg and hip. Employee #1 was hospitalized.
