Apartment Building, Nursing Home/Senior Living, Residential Prior Lake, MN – Sprinkler system stops fire at senior apartment building; No injuries reported December 31, 2017 viking210 The Prior Lake Fire Department responded to a cooking fire at the Grainwood Apartments building Tuesday night. With temperatures dipping below zero degrees around 7:15 p.m., when firefighters responded to the scene, 5119 Gateway St. SE, Fire Chief Rick Steinhaus said he was happy that a sprinkler system within the building extinguished the fire almost immediately. “It did what it was supposed to do,” he said. The building was evacuated due to the fire and three units were displaced due to “extensive water damage” from the sprinkler system, Steinhaus said. There was very little fire damage, the chief said. Steinhaus said Tuesday night’s fire is a good example of why the state of Minnesota has been fighting for sprinkler systems in all commercial buildings. “It’s considered a sprinkler save,” he said of the fire. The Grainwood Apartment complex held its grand opening in August. The building includes 168 living units plus community areas, which include a kitchen, craft room, salon, fitness area, theater and underground heated parking. The building is for adults age 55 and up.
