Boston firefighters responded to an electrical fire at the State House on Tuesday afternoon, a spokesperson for the state police said.

Boston firefighters responded in mass just after 2 p.m. and quickly gathered on Derne Street, where several trucks started extending their ladders towards upper-story windows.

State police spokesman Dave Procopio said no injuries were reported and “at this time, it appears the fire was confined to the basement.”

“The fire is in a transformer room in the building’s sub-basement. Companies are awaiting electrical utility to cut power before they make entry to extinguish the fire. There are smoke conditions in other parts of the building,” Procopio said in a statement just before 3 p.m.

A spokesperson for the Boston Fire Department confirmed companies were responding but did not have additional details.​

Hundreds of staffers, lawmakers, and members of the public calmly flooded into a private parking lot before officials asked everyone to move away from the building.
