PEORIA, Ill. -- Authorities are investigating the cause of an overnight explosion that caused a temporary shutdown of operations at the Archer Daniels Midland plant in Peoria.
The company says it called the fire department around 3 a.m. and that operations at the plant have been halted until further notice.
All of the ADM employees have been accounted for.
For much of the early morning, the sustained tone of the siren alarm could be heard at the plant. Additonally, firefighteres shut down Washington Street between Chicago and McArthur.
Authorities say the explosion occurred in the boiler area of the plant.
"They're very very lucky," said Division Chief Ed Olehy. "I mean, the personnel there are very lucky. They had, like I said, no injuries that we know of. In a blast like that, it could have very easily, you know, taken out many people."
As is customary, the Occupational Safety and Health Administration, along with the state fire marshall, will join local authorities in their investigation of the explosion and fire at the ADM plant in Peoria.
Damage is estimated in the million dollar range.
