A fire in the ventilation system at the Inteplast Bag and Film Corporation had crews busy over the lunch hour.
District Fire Chief Joe Armstrong tells CHSJ News the call came in as a fire alarm activation but was upgraded to a structure fire.
The fire was attacked from the roof and knocked down.
He says investigators are on scene and it appears the fire began in a peice of machinery which caused plastic and other debris to catch on fire.
