PITTSFIELD — A small fire in Cianbro's fabrication shop Thursday was out nearly as quickly as it started.

The fire caused no damage and employees at the Hunnewell Avenue facility were able to return to work, said Captain Mike Havey of the Pittsfield Fire Department.

The fire, which was reported a little before 2 p.m., likely started in a dust collector, Havey said.

"They think the wheel that collects the dust got off center and was rubbing against metal," Havey said. The resulting sparks likely nestled into the filters and touched off the blaze.

"That's the only thing that was burning when we got there," Havey said. "They had it mostly out."

Cianbro is one of the East Coast’s largest civil and heavy industrial construction, and construction services, companies.
