Burlington firefighters started their Thursday by battling a four-alarm blaze that broke out in a historic building on the University of Vermont campus.

VtDigger reports that no one was injured in the fire, which took much of the day to extinguish. The building, known as Torrey Hall, had been undergoing historic preservation work, which is thought to have caused the flames, according to Burlington Fire Chief Steven Locke.

“We’re pretty confident the fire was started by workers soldering copper,” Locke said.
