Marlborough Condo Condemned After Hazmat Incident

MARLBOROUGH, MA — A hazmat situation at a Marlborough condominium complex ended Wednesday night with one unit in the building being condemned by the health department, according to fire officials.

Marlborough firefighters went to the 36-unit 624 Boston Post Road East building near 3 p.m. Tuesday for a medical emergency. A 35-year-old man living in one unit was taken to Marlborough Hospital.

While there, firefighters noticed a "large quantity of unknown and unlabeled substances resembling hazardous materials in various forms (liquids, solids)," the fire department said in an incident report.

"Further investigation confirmed the presence of vast quantities of unknown, unlabeled substances. Additional resources were requested to continue to assess the situation and evaluate potential dangers to responders, building occupants and the public," the department said.

The building was evacuated, and the state police bomb squad, the state Department of Fire Services, FBI, Marlborough police and state environmental officials responded to investigate the materials. Officials were still trying to determine what the chemicals were as of Thursday morning.

State police destroyed the chemicals at a city landfill on Wednesday night.

The residents were allowed back into the building around 6 p.m. Wednesday, Assistant Chief Jeffrey Gogan said. About 12 residents were given emergency shelter at a Marlborough hotel during the incident.
