Crews are battling a fire at a large storage unit in Thomaston on Monday morning.
Firefighters were called to the storage unit building on River Street around 2 a.m.
When crews arrived, they said they found a large amount of fire in one of the bigger units where there is car, truck and boat storage.
The fire has since spread to the other units that are smaller and contain mostly home furnishings and people's belongings, fire officials added.
Fire officials said one of the challenges is moving the debris and stuff that's in storage to be able to get the fire out and an excavator has been brought in to help.
Firefighters from about 16 fire departments have responded to the scene to help fight the flames especially with the heat and complexity of the building, according to authorities.
There is no word on what may have started the fire. The state and local fire marshals are on the scene investigating.
The state Dept. of Energy and Environmental Protection has also been called to the scene to monitor the runoff.
No injuries were reported.
