On 2/6/07 around 11:30am, the #1 dryer was shut down to make some adjustments on the PLC Controllers. Around 11:45, plant people noticed flames coming out of the ID Fan Piping, at that time we got the fire hose located in the dryer room and began to spray the fire. The fire dept was called out to assist, fire was extinguished around 12:20pm. No one was hurt.
