A fire that started in a Christmas tree raced through a three-story apartment building in Dorchester on Monday, displacing eight adults and two children, authorities said.
Firefighters responded to 86 American Legion Highway just after noon for a blaze that was spreading up the building.
A resident of the second floor was dragging her Christmas tree out to the outdoor porch when a branch accidentally turned on a stove burner, said Steve MacDonald, spokesman for the Boston Fire Department.
“The tree was fairly dried out after being in the apartment for several days, so it ignited pretty quickly and the fire spread right out the window and up to the third floor,” MacDonald said.
One person was treated and taken to the hospital by Boston EMS for cuts to the shoulder and leg, MacDonald said.
The American Red Cross also responded to assess the needs of the displaced residents. They all arranged other places to stay, the Red Cross said.
Fire Department officials estimated damages at $250,000, mainly due to significant smoke on the second and third floors and water damage on the first floor of the right side of the building.
It was unknown how long residents could be displaced, but MacDonald estimated at least a couple months.
“It depends on how quickly the property management can get contractors in to vacuum up the water, check electrical systems, and repair broken windows,” he said.
