Apartment Building, Residential Sprinkler system extinguishes apartment fire in second floor bedroom (Boise, ID) July 18, 2012 viking210 Fire officials say an four-plex building in South Boise avoided major fire damage late Tuesday night thanks to a sprinkler system that put out a blaze before crews got there. When crews arrived, they found that the sprinkler system in the building was able to put out the fire before it could spread. The fire ignited after a candle fell off a window sill in the bedroom of a second-floor unit but did not spread to the sheetrock — or anywhere else in the apartment.
