Firefighters from several departments battled a two-alarm fire at the Jackson Laboratory Tuesday.
The fire call came in at about 1 p.m. and within minutes of arriving, Bar Harbor Fire Chief Matt Bartlett determined there was an active fire inside a vessel within Building 65, a boiler building.
The department called for more manpower and the fire was contained, with firefighters at the scene for approximately 90 minutes.
The fire was in a “hopper” in the boiler building, Bartlett said.
Crews from Bar Harbor, Southwest Harbor, and Mount Desert Fire Departments, along with island coverage from Trenton, helped douse the blaze.
At this time they have not determined the cause of the fire, Bartlett said.
The lab’s Bar Harbor campus has been its headquarters since 1929 and includes 68 buildings on 169 acres.
