Decatur Fire Department Battalion Chief Wade Watson said six of the eight workers were immediately taken to the hospital for medical treatment, according to The Associated Press (AP). While the cause of the explosion is still under investigation, Watson reportedly confirmed the fire department had everything under control. The explosion, which caused a fire, sent a large black plume of smoke into the air above the facility, per a video shared by ABC 7 Chicago.

The Decatur site is ADM’s largest facility globally. It is home to a soybean crushing plant and one of the world’s largest corn wet mills in the world, according to Reuters.

Additionally, the facility has the capacity to produce 375 million gallons of ethanol biofuel every year, the most in the United States, according to the Renewable Fuels Association. (RELATED: Engine Fire Prompts Evacuation Of Passengers From Flight, Nine Injured)

Further information regarding the incident is yet to be disclosed to the public.
