A Thursday morning fire in The Dalles claimed the life of one person, and an investigation determined the fire was caused by use of a heat lamp. Mid-Columbia Fire and Rescue says the fire occurred just after 8 a.m. Thursday morning at 814 West 18th Street, with crews finding a thick dark column of smoke coming from the home, which was fully involved in the fire. Crews had to focus suppression efforts from a defensive position to protect exposed homes and property in the area due to reports of large explosions at the initial stages of the fire, a potential ammunition storage hazard, and the fully involved structure. An adjacent home also caught fire, but crews wear able to keep the damage limited and the structure is habitable. One victim, whose name has not yet been released, was found deceased at the scene. An investigation by MCFR, The Dalles Police Department, Oregon State Police, and the Oregon State Fire Marshal determined the fire was caused by the use of a heat lamp in the basement sleeping area of the structure. Personnel from MCFR, Dallesport, Dufur, Wy’east and Mosier Fire Departments, the Oregon Department of Forestry, The Dalles Police, Wasco County Sheriff’s Office, and Wasco County Emergency Management were involved in the fire response.
