PAWTUCKET, R.I. (WHDH) — Fire crews worked to put out a blaze that erupted after a home exploded in Pawtucket.

The explosion happened just after 10 a.m. Tuesday in a triple-decker home on Mineral Spring Avenue. Firefighters had the blaze under control within an hour.

"We got down here and you could see they were up on the third floor and it was dine open. They were just walking around not knowing what the hell was going on like they were in shock," Robert Garrey, a man who helped rescue the occupants, said.

An infant and a badly burned man were taken to the hospital after good Samaritans helped rescue the occupants inside the home.

Garrey tells WPRO-AM that he helped three people out of the building. The Central Falls man says the infant appeared to be OK but the man's burns were significant.

Eric Silva who lived on the first floor of the building helped get his girlfriend and baby out of the building, then ran back in to help the other residents.

“I went back inside and checked to see if anybody was on the second floor. Me and another guy kicked the door down and then nobody was there. Then we went upstairs and another guy got them out upstairs, then we got the baby and ran outside,” Silva said.

Off-duty Providence firefighter Jermaine Woods also entered the building and helped get those inside to safety.

Rhode Island Fire Marhsall John Chartier said the building is unsafe for investigative crews to enter and finding the cause of the fire may take some time.
