CHARLTON (FOX 25 / MyFoxBoston.com) - Fire officials are seeking the cause of a five-alarm fire that destroyed a warehouse at a mill complex in Charlton. It's the second largest blaze they've ever fought.
Firefighters from about 20 towns battled the blaze that started around 9 p.m. Thursday at the Charlton Woolen Mill on City Depot Road and burned for more than two hours.
Several explosions were heard, possibly caused by old propane tanks stored inside the mill.
Six firefighters were injured with problems related to high blood pressure and carbon monoxide.
Assistant Fire Chief Curtis Meskus says because there is no municipal water supply, a tanker shuttle had to bring in water from Glen Echo Lake.
The mill complex, at City Depot Road and Route 31, houses 10 businesses. It was unclear Friday how those businesses would be affected.
One of the businesses is a luxury car restoration company. The owners say they lost millions in expensive innovatory.
The fire is not believed to be suspicious, but a cause has yet to be determined.
