The Butler County Coroner's Office has identified the worker killed on Tuesday at a Middletown steel mill.

Wessley Thomas Blanton, 46, of West Carrollton, died as a result of head trauma, according to findings from the coroner's office.

Following an autopsy, the coroner's office ruled Blanton's preliminary manner of death as an accident, according to a news release. 

The incident occurred at Middletown Works during planned maintenance at the facility's hot strip mill, according to a statement released by the company Tuesday afternoon.

Officials said Blanton died as a result of injuries he sustained during "a routine operation."

"Cleveland-Cliffs expresses its deepest sympathies to the employee’s family and the Company will provide the necessary support to the family during this difficult time," the company's statement reads.

Company officials said an investigation will be conducted with the International Association of Machinists and Aerospace Workers as well as the Occupational Safety and Health Administration.

Federal records show OSHA opened an inspection of the facility on Tuesday.

The Middletown Works facility is "an integrated steel operation with carbon steel melting, casting, hot- and cold-rolling and finishing operations," according to the company's website.
