Indiana Township, Allegheny County - On August 15th, at 9:24 P.M., fire crews were dispatched to the 200 block of Little Deer Creek Road for a working house fire called in by local police. Due to a bridge out on the road, two additional companies were immediately dispatched to assist. Crews arrived to find a fully involved home with extension into the roof a neighboring home. Crews set up a defensive attack on the main home while other crews quickly knocked down the fire in the exposure home. At one point, a Mayday was called for a firefighter that collapsed in the yard. Crews quickly removed the firefighter and were treated on-scene by medics. Crews had a tough time extinguishing the fire due to live power lines. Once the power was shut off, crews were able to knock down the rest of the fire. The fire was placed under control at 10:33 P.M. Both homes were occupied at the time but everyone made it out. The fire is now under investigation.
