The company said it has been working with authorities to determine what caused the incident, and expects the Tennessee Occupational Safety and Health Administration to release its final report within the next two months.

Gerdeau said it won't release personal information on the employee who passed away because of company policy and respect to the family.

The accident occurred on May 15 while employees were melting down scrap metal.
