Two workers have died from carbon monoxide poisoning at an agricultural products plant in central Illinois.
Officials say the two workers were cleaning a rail tanker car at Agridyne LLC in Pekin, a company that manufactures and sells liquid feed.
Workers became overcome by carbon monoxide that had built up inside the car.
One worker fell into the rail tanker car before his colleague made an attempt to rescue him, but was overcome as well.
Crews are still investigating what led up to the accident.
