CRANSTON, R.I. (WPRI) — An investigation is underway after a fire broke out early Monday morning in Cranston.

Crews responding to the scene on Westwood Avenue just before 3 a.m. found a lot of smoke.

Sean Swpeson, who lives in one of the homes, told 12 News he is crediting his two dogs for getting him and his family out safely.

“I ran out and saw my van was on fire. I tried to put it out with the hose and then realized I wasn’t doing that,” he recalled. “I went inside, called 9-1-1, came back out, and saw it was completely engulfed, so I got everybody out of the house, and thank god everybody is OK.”

One of his family members was walking back inside the home when the front windows shattered from the excessive heat, Swepson added.

Two firefighters were taken to the hospital with minor injuries.

Both homes have been deemed uninhabitable and the Red Cross is helping the displaced residents.

It’s unclear what caused the fire.
