FARRELL, Pa. (WKBN) — A house in Farrell was destroyed after a fire Monday morning.

Crews were initially called for reports of smoke in the area of Wallis Avenue just after 7 a.m.

While firefighters were knocking down flames, Farrell’s Fire Chief Mike Renner said they heard a dog inside.

The people who lived in the house confirmed that the dog was in the basement. Crews were able to get the dog out alive and begin treating it on the scene. It was then sent to an emergency veterinarian.

One firefighter was injured due to smoke inhalation from mechanical failure but was also treated at the scene.

Crews were initially called for reports of smoke in the area of Fruit Avenue about a block away.

“They [the firefighters] bypassed that and came here to the structure. It was a working fire, fully involved. All floors had active fire going when first units arrived,” Renner said.

He also said this is a common time of year for fires inside homes and reminds everyone of the importance of having working fire alarms in the home and being mindful of secondary heat sources like space heaters.

“Especially when you have issues with utilities you need to watch secondary heat sources, like space heaters or using your oven or anything like that … for heat,” Renner said.

The Pennsylvania State Police’s Fire Marshal is investigating the cause of the fire.
