Investigators believe an electrical failure caused a residential fire that destroyed a two-story house in Klamath Falls Wednesday morning. According to Klamath County Fire District 1, an “electrical overload” was likely the cause of a fire on the 800 block of North Eighth Street. Crews were dispatched to the fire at 5:52 a.m. and were told an occupant may be inside. They confirmed the resident was out of the house and the fire resulted in no injuries to crews or civilians. Damage from the fire was estimated at $150,000, a total loss for the house. District 1 was assisted in their response by the Office of the State Fire Marshal and Klamath Falls Police Department. A District 1 news release Wednesday said residents should be cautious of how they employ electrical heaters during cold weather.
