Firefighters and investigators will be back at a corn mill in southern Wisconsin Friday to look for the cause of a deadly explosion.
The blast happened at the Didion Corn Mill in Columbia County, Wisc, halfway between Madison and Fond Du Lac.
Recovery crews have been sifting through a mountain of debris. At least one mill worker died and more than a dozen other workers were injured.
The plant processes corn for food use, including corn flour, grits, and meal. There’s also an ethanol plant on-site, but it was not involved in the explosion.
The Wisconsin State Fire Marshal’s office has been called in to assist in the investigation. A spokesman says it could be weeks before they pinpoint a cause.
The Associated Press says OSHA cited the plant in January 2011 for “exposing workers to hazards associated with dust explosions.”
According to the AP, Didion payed a $3,500 fine and the case was closed. There have been no citations since then.
