A control room at a long-standing steel plant in south suburban Riverdale was badly damaged during a fire Tuesday night.
A fire started about 8:30 p.m. inside a control room at Mittal Steel, 13500 S. Perry Ave., and was contained to the single room, a Riverdale Fire Department firefighter said.
The fire was extinguished about 9:15 p.m.
The facility was “pretty damaged,” the firefighter said. The estimated cost of the damage was not available.
The firefighter said some employees were at the plant, which makes steel coils, but no one was injured.
Mittal Steel, the former Acme Steel Company, has been located on South Perry Avenue since approximately 1910, according to the company Web Site.
The cause of the fire is under investigation.
