Excerpts from wandtv.com:

Two Decatur firefighters were taken to the hospital after responding to a third-alarm fire at ADM’s East Plant, that was detected by employees in the feed house of the corn processing plant at ADM’s Decatur complex during some maintenance activities Monday. 

The plant was evacuated, and all employees were safely accounted for.

First arriving crews from the Decatur Fire Department found heavy fire and smoke from the industrial structure that contained process tanks. They accessed the fire area and discovered heavy fire in a processing tank that was spreading into adjacent tanks. Large attack lines were deployed from a ladder truck to keep the fire from spreading to the rest of the structure while ADM employees injected steam and water into tanks.

The incident commander upgraded to a third alarm. Crews were on scene for 12 hours before the fire was completely under control.

Two Decatur firefighters were transported to the hospital. One was treated and released and the other was admitted for observation.
