An explosion blew out the wall of a building on Farren Avenue in New Haven on Friday afternoon, sending a woman to the hospital.
The explosion and fire happened around 3:50 p.m. at 95-97 Farren Avenue.
Crews found a woman outside the building who had suffered burns in the fire. She was rushed to Yale-New Haven Hospital and then transferred to the Burn Unit at Bridgeport Hospital, according to fire officials.
Ten adults and seven children were all accounted for after the explosion and fire, officials said. All were residents in apartments in the building.
Mohammed Choudary made a run for it from his first-floor apartment.
"Everything is lost and maybe something will be left over," he said.
The fire was brought under control around 5 p.m.
"I was watching the living room TV and there was a noise," said Takshesh Patel. She also lived in the multi-family home.
The Fire Chief said there were multiple calls for an explosion and it appears something caused the outside walls to blow out, but the cause is still being determined.
The building owner is assisting the families displaced by the fire and will provide them with alternate housing.
Fire investigators will be at the scene throughout the night working to determine the cause.
