An industrial building in Woburn was evacuated Friday due to a dangerous mixture of chemicals, according to the state fire marshal’s office.

A level 3 hazmat situation was declared at the building on Roessler Road, but there were no injuries, said Jake Wark, a spokesman for the office.

It was determined that the incident was caused by “the accidental mixture of two substances” which caused a chemical reaction.

Wark did not identify the chemicals involved.

Woburn fire crews responded to the scene, along with state hazmat teams, Wark said. The situation was stabilized as of 11:40 p.m.

“Fire apparatus will remain on-scene overnight as a precaution,” Wark said.


Woburn police and fire said no information was available.
