Cleveland Cliffs officials are providing more information on a hydrofluoric acid leak that sent multiple people to the hospital Thursday morning.
A spokeswoman for the company said contractors were working on an abandoned hydrofluoric line in the morning when there was a minor contained leak.
The scent of fumes was then detected in the area. The spokeswoman said six contractors and one Cleveland Cliffs employee were taken to the hospital as a precautionary measure.
The individuals were given a preventive breathing treatment. All seven people returned to work later in the day.
