ADAMS, Mass. — Officials from the State Fire Marshal's office reported that the structure fire at the old MacDermid Graphics building remains under investigation.

 

"The investigation is still open, and given the scope of the damage it may take a while," said Jake Wark from the State Fire Marshal’s Office.

 

A large fire broke out Wednesday morning around 7:30 a.m. at the old MacDermid Graphics building, drawing a massive response from fire companies across the region, forcing school closures and prompting a large firefighting effort to contain the blaze at the vacant mill.

 

The Adams Fire Department later reported that firefighters fought the blaze for 12 1/2 hours, finally clearing Harmony Street around 6 p.m.

 

Approximately 22 agencies and 100 responders assisted at the scene after a second alarm was requested.

 

No firefighters were injured.

 

During the fire, an alert was sent out cautioning residents with breathing issues to shelter in place due to potentially toxic materials burning in the building. Adams Fire officials reported that the state Hazmat Team did respond.
