On March 30, 2015, at approximately 7:30 a.m., employees were using an overhead crane to move a sub-product (billet) from a lower level to a higher level. When the billet was situated on the higher level, the chain loosened; it toppled over and fell the down the stairs, striking the employee who was coming up to unhook it. The employee was hospitalized with a scalp laceration and spine fractures.
