A 5-alarm fire broke out Wednesday night at a recycling plant in Salem, New Hampshire, and crews remain on scene Thursday morning.
Police say officials were called around 8:45 p.m. to L.L.S. Wood Recycling on Lowell Road. The fire started on a pile of debris before spreading to the structure.
The flames could be seen from I-93 across Salem.
According to officials, the building was unoccupied.
Fire chief Paul Parisi said the large piles of debris span an area just under the size of a football field - making for a difficult and dangerous situation for firefighters.
No injuries have been reported. Crews say they will remain on the scene throughout the morning to take care of hot spots.
