PAWTUCKET, R.I. (WPRI) — An investigation is underway into the cause of a fire that tore through a Pawtucket home Monday evening.

Firefighters rushed to the Paisley Street home to find flames shooting from the roof and smoke pouring from the second-floor windows.

It took firefighters roughly two hours to knock down the flames. Pawtucket Battalion Fire Chief David Cairrao said the fire appears to have started on the first floor.

The situation took a turn for the worse when a Providence firefighter fell through a set of stairs inside the home, prompting a mayday call, according to the Providence Fire Department Union. The injured firefighter kept his composure and escaped the building on his own, but was brought to the hospital for treatment.

Cairrao said a Pawtucket firefighter was also transported to the hospital with chest pains. Both injured firefighters are expected to be OK.

Five adults and two children who live in the home have been displaced, according to Cairrao.
