Apartment Building, Residential East Wenatchee, WA – Sprinkler system limits damage in apartment kitchen fire; No injuries reported September 20, 2017 viking210 The sprinkler systems that are required by code in East Wenatchee apartment buildings worked perfectly Monday to keep a stove fire from spreading according to fire investigator Brian Brett. Crews were called just after 11am to the Bello Rio Apartments in the 2-thousand block of Northwest Cascade Avenue. That’s where Brett said a fire began in one of the apartment units when French fries were left cooking. Brett said the sprinkler systems are required by code in multi-unit apartment buildings and in this case, prevented the fire from spreading. Damage was confined to the wall above the stove area.
