BURNS HARBOR, Ind. - An explosion rocked a steel mill in northwest Indiana on Tuesday afternoon, rattling nearby residents and producing a plume of smoke visible miles away, though no one was injured, officials said.
A Cleveland-Cliffs spokesperson told FOX 32 News the blast took place in a slag pit at the mill along the Lake Michigan lakeshore in Porter County. Steel slag is a molten liquid byproduct of the steelmaking process, and it is taken to pits where it solidifies as it cools.
The spokesperson said the explosion resulted in a minor fire that was extinguished quickly.
United Steelworkers Local 6787 President Pete Trinidad said no one was injured "and everything is under control."
The Burns Harbor mill is Cleveland-Cliffs’ second-largest U.S. facility, and can produce almost 5 million net tons of raw steel per year, according to the company’s website. The fully-integrated mill operates two blast furnaces and primarily produces hot-rolled, cold-rolled and hot-dip galvanized steel products.
