SACO — An industrial fire destroyed a dust-collecting machine at Casco Bay Steel early this evening.

No one was injured and the fire did not spread from the equipment to the building at 75 Spring Hill Road, said Fire Department Captain Vincent Pelletier.

The fire began about 5:30 p.m. and took about an hour to put out because it involved a flammable metal that was being used in a sandblasting process, he said.

The large piece of equipment, valued at about $100,000, was a total loss, he said.
