A crew was removing steel beams from the work area using a fork lift. There were 10-foot and 30-foot sections of steel beams stacked on dunnage next to each other. After allowing employees to clear approximately 25 feet away from the lift, the forklift operator began to lift a 10-foot section of steel beam. The bottom left flange of the 10-foot beam being lifted caught the top flange of the adjacent 30-foot beam, causing it to fall off the dunnage and onto an employee's foot. The employee's left foot and toes were crushed by the steel beam, resulting in hospitalization.
