A firefighter was treated for burns after rushing into what authorities called a suspicious fire Tuesday morning at a house in Dunedin.

The firefighter, who was not identified, has been with Dunedin Fire Rescue for five years, a spokesperson said.

Deputies and crews responded to 1965 Sourwood Boulevard around 8:30 a.m. and found the front of the home engulfed in flames. A woman who lives there had managed to get out safely, but firefighters didn't know that, and at least one went inside to help her get out.

"When we get the message that there's someone inside, we gear up and go inside," Dunedin Deputy Chief Trip Barrs said. "The gear is very good, but with some of the temperatures we encounter, the gear's just not able to protect us fully."

The injured firefighter suffered first- and second-degree burns to his face and legs.

The woman who escaped the home was taken to Mease Dunedin Hospital. A neighbor was evaluated for smoke inhalation, then released by paramedics at the scene.

Two dogs and three birds were rescued from the house.

Investigators from the State Fire Marshal's Office and Pinellas County Sheriff's Office are investigating the fire. They did not say why they believe the fire to be suspicious.
