EAST CHICAGO, Ind. — The owner of a northwestern Indiana steel mill has agreed to pay a $7,000 fine over what state inspectors determined was a serious safety violation in a worker’s death.

The inspection began after Robert Watts, 62, of Westville fell into scalding water in an 8-foot-deep sinkhole Feb. 8 at the ArcelorMittal Indiana Harbor mill in East Chicago. He died March 20 at a Chicago hospital.

The Indiana Occupational Safety and Health Administration cited the company for not putting railings around the 11-feet-by-9-feet hole or having someone monitoring the area. Watts and another worker were repairing a pump when he fell.

The safety agency says ArcelorMittal corrected the violation during an inspection.
