BOSTON (CBS) - Firefighters quickly brought an eight-alarm fire in a commercial building in Boston under control early Tuesday morning.
According to WBZ NewsRadio 1030's Carl Stevens, flames broke out around 4:30 a.m. in a five-story brick building on Summer Street near South Station and the Convention Center.
Within minutes, it raged out of control and jumped to eight alarms. Windows on the first three floors were blown out and firefighters were ordered not to go into the building.
But they had it under control in about an hour.
The building was under renovation and everyone inside escaped safely.
According to the Boston Fire Department, cleaners were in the building at the start of the fire. Firefighters had to force open the front doors, but the cleaners got out the back door.
One of the construction workers told Stevens that he believed the fire started with an explosion of a machine on the second floor.
There's no official word yet on a cause.
Traffic will likely be a problem in the area for the morning commute. Summer Street is closed from D Street to Atlantic Avenue.
A Street will be closed between Congress and Melcher.
