DUNSTABLE — A two-alarm fire in a large commercial building was extinguished by the Dunstable Fire Department and mutual aid partners on Tuesday afternoon.
At approximately 3:30 p.m., the Dunstable Fire Department received a 911 call reporting a fire with a possible explosion at a commercial facility at 41 Lowell St.
The first responders on scene found smoke and fire showing from the roof and exterior walls.
A second alarm was struck to bring additional manpower to the scene.
Due to the lack of fire hydrants in the area, crews had to stretch several hundred feet of hose line from a nearby pond to establish a reliable water supply.
The fire was initially attacked from outside of the building, which was closed and not occupied at the time.
Crews later gained access and attacked the fire from inside the structure until the building’s roof became compromised and in danger of collapse.
No injuries were reported.
The building suffered extensive damage to its roof and attic space.
The cause of the fire is under investigation by the Dunstable Fire Department, with assistance from the State Police Fire and Explosion Investigation Unit attached to the State Fire Marshal’s Office.
Firefighters from Pepperell, Groton, Tyngsborough, Townsend, Westford, Ayer, and Hudson, Hollis and Nashua, New Hampshire provided mutual aid at the scene.
PrideStar EMS also responded.
Firefighters from Ayer covered Dunstable stations.
“Companies did a great job establishing a water supply and knocking this fire down before damage was even more extensive,” said Chief William Farrell. “I would like to thank all of our mutual aid support on this fire as well. Their assistance was invaluable.”
