Nursing Home/Senior Living, Residential Prescott, AZ – Fire at senior apartment complex contained by sprinklers June 15, 2015 viking210 Three residents were unable to return to their apartments at Alta Vista Retirement Apartments after fire crews responded Friday afternoon, June 12, in what turned out to be a box left on a stovetop. Prescott Fire Department Battalion Chief Eric Kriwer said the department was dispatched at approximately 2:15 p.m. to the apartments in the 900 block of Canterbury Lane, responding with four engines and a company truck. He credited the sprinkler system at the apartments with preventing a more serious outcome. Occupants of some 50 residences evacuated the building as crews looked for extensions throughout the building. Two people were treated for lightheadedness and transported by ambulance to the Prescott campus of Yavapai Regional Medical Center. The ensuing investigation revealed a fifth-floor resident had left a box on the stove and apparently turned on a burner, which ignited the cardboard and triggered the sprinkler system in the kitchen area. Kriwer said three residence were displaced and the property loss is still being calculated.
