NORTHBOROUGH, Mass. (MyFoxBoston.com) -- Emergency personnel responded to a Level 2 hazardous materials situation at an industrial complex in Northborough, Thursday morning after ammonia gas was emitted and vented in a room according to the city's fire department.
Firefighters responded to the scene at Goddard Road at around 9:20 a.m. after employees in the room noticed the gas coming through. The building, which is part of a five-building research complex, was shut down and evacuated.
Firefighters called in the hazardous materials team after learning ammonia was the chemical being emitted.
The gas was contained to one room because of the quick-acting employees, fire officials said. Once firefighters and the hazmat team could no longer detect a level of ammonia, at around 12:30 p.m. the building was reopened and employees allowed to return.
