Boston Fire officials said a 7-alarm Back Bay fire that displaced 40 residents and injured three firefighters was caused by the careless disposal of smoking material.
The fire tore through the six-story building located at 31 Mass. Ave. on Saturday afternoon after the smoking material sparked the blaze in a rear 5th floor apartment, fire officials said.
Damage was estimated at $2.5 million.
Fire spread to the 6th floor, and drew 150 firefighters to the scene.
Three firefighters were treated at local hospitals; one for smoke inhalation, one for a neck burn and another for a wrist injury.
The building, because of its age, did not require sprinklers throughout the building.
Boston Mayor Martin Walsh appeared at the scene, and said he would work with state legislators to prioritize safety in buildings that had been grandfathered in under outdated fire regulations.
Fire Department spokesman Steve MacDonald said narrow stair wells made it difficult for firefighters to extinguish the blaze.
Red Cross, and the Fire Department’s Victims Assistance Unit were helping with displaced residents.
