A steel worker in Gary, Indiana was seriously injured in an on-the-job accident this week, suffering multiple fractures after a car fell off of a rail and landed below. The man was airlifted to Loyola Hospital with a number of serious injuries, including a possible dislocated hip. He is in serious but stable condition.

The man, who has yet to be identified, was an employee of U.S. Steel Gary Works and was operating a transfer car at the time of the serious worker accident. The cars, which run on a rail, transport materials to the blast furnaces and are operated by a single worker. When a grinder under the car, which carries lime and coke, failed, the car tipped over and fell approximately 25 feet. The man was inside the car and suffering serious injuries when the car fell on top of him.

A union spokesperson said that the Indiana employee accident was likely caused by aging infrastructure or a lack of ongoing repairs. The representative said that the company knew that repairs were needed, but orders for contractors had been cancelled in the past.

The deadly worker accident is being investigated by the Indiana Occupational Health and Safety Administration as well as by U.S. Steel itself. U.S. Steel says that the company takes safety very seriously and will use the results of their investigation to make needed repairs and ensure that their workers have a safe environment.
