A house explosion in Dorchester on Wednesday night sent 12 people to the hospital and blew the door off of the building, sending it flying across the street, according to fire department officials.

A spokesman from the Boston Fire Department said crews responded to the scene of the explosion on Hansborough Street around 9:20 p.m., after the blast caused a partial collapse of the two-and-a-half story house, rocking it off its foundation.

As a result of the explosion, which sent a door from the house soaring across the street from the property, a three-alarm fire broke out, and responders had to combat the flames from the exterior due to the poor conditions of the residence.

“[There was] heavy fire on arrival in [the] basement and upper floors. Partial collapses on both sides of the house,” Boston Fire Department spokesman Steve MacDonald said.

Workers from Boston’s Emergency Medical Services responded to the house explosion and remained on scene as firefighters battled the blaze. Officials from EMS said they transported 12 people to area hospitals with undetermined injuries. Those treated were residents of the home. First responders also evaluated a few additional people for minor injuries at the scene.

The fire was knocked down just after 10:30 p.m., MacDonald said in a Tweet sent out through the department’s official account.

The cause of the explosion was not immediately known.
