What was that noise? Saugus fire officials explain loud boom

People in Saugus, Massachusetts, who heard a loud noise Monday night can rest assured that there is no danger, fire officials said.

The Saugus Fire Department said the explosion-like sound was the result of a turbine malfunction at Wheelabrator Saugus, a WIN Waste Innovations facility.

Police and firefighters responded, but no one was injured and there is no danger to the public, officials said.

Neighbors of the Wheelabrator plant, a trash-burning facility on Salem Turnpike, have long complained about noise.

"It sounds like a train or a jet engine starting," longtime resident Joan Beaton told NBC10 Boston in 2019.
