Fire broke out in ductwork at the Maryland Paper Co. on Elliott Parkway Tuesday morning but the blaze was extinguished with no damage to the building, according to the chief of the Williamsport Fire Department.
The Maryland Paper Co. is a scrap paper-recycling operation and the ductwork is used to remove steam exhaust as paper is being dried, said William Ball.
Creosote, a very flammable byproduct of combustion, can build up in the ductwork, Ball said.
The fire activated the sprinkler system in the building and firefighters finished extinguishing the blaze, Ball said.
The fire was reported at 8:09 a.m. and firefighters were finished at the scene at 8:56 a.m., officials said.
