Firefighters were called to the scene of a fire around 2:30 a.m. this morning at a more than 100 year old home in Maple Valley.

According to a release from the Puget Sound Regional Fire Authority, the home owner and their dog were able to get out of the home safely while the fire quickly spread through the first floor.

He attempted to use a garden hose to fight the flames while waiting for crews to arrive.

The release added that some homes built in the 1900s, like this one, used sawdust as insulation, making it harder to extinguish hidden, smoldering fires.

While firefighters were fighting the flames, the electrical power line from the street to the home lost its insulated coating and the wire grounded to the home, the release stated. A firefighter unknowingly placed his hand on a deck rail and was electrocuted.

He was able to walk himself to the medic unit and was taken to the hospital for observation.

American Red Cross arrived on scene to assist the home owner.

Units from Renton Regional Fire Authority and Puget Sound Fire assisted Maple Valley Fire and Life Safety.

The cause of the fire is currently under investigation by the King County Fire Investigators.
