Abstract: At approximately 2:15 p.m. on December 2, 2005, Employee #1 was connecting steel components on a steel frame building structure. Employee #1 was working from the top rail of a JLG aerial device, hanging a girder truss to a knife plate connector at approximately 30 ft above ground level. Employee #1 had his right hand near the two pieces of plate when he looked down and reached toward the JLG rail with his left hand (in order to hook on his fall restraint to the rail). Employee #1 inadvertently raised his right hand approximately 2 in. into the pinch point between the girder truss and the knife connector plate. Employee #1's right ring finger was pinched between the two pieces of steel resulting in him sustaining a broken tendon to his right ring finger. Employee #1 was treated at the emergency room and was released.
