## Narrative

There was a plugged condition in the discharge area of the Rotary Hearth Furnace which we believe resulted in uncontrolled combustion of CO.  There were no injuries and no damage to equipment.  This does not constitute an admission that an ignition occurred.  This report is filed out of an abundance of precaution.
