An employee was operating an overhead crane to move a 31" x 27" x 10" piece of machined metal with a hole through the middle weighing approximately 1,350 pounds to prepare for the next welding operation. The material was 16-20" above the ground when the lift strap broke and the material fell onto the employee's lower legs. This caused him to fall backward and the material landed on his left foot. The employee sustained bruising and scraping injuries to the legs from the knees down to the ankle, as well as a foot injury.
