Apartment Building, Residential Kalamazoo, MI – Sprinkler system assists firefighters in containing fire at large apartment building September 5, 2015 viking210 The Kalamazoo Department of Public Safety received multiple 911 calls around 8:20 a.m. Friday morning regarding a fire at an apartment located in the 2700 block of W. Michigan Avenue. Police say the fire activated the sprinkler system which was able to contain the fire to the apartment where it started. No one was injured. When officers arrived on scene, they saw smoke coming from a second floor apartment on the north side of the building and residents already evacuating. The fire was contained in about a half hour; however, due to the large number of apartments in the building, a second alarm was called which brought more emergency crews to the scene. A total of eight fire apparatus and about 35 firefighters responded. Police closed W. Michigan Avenue near Howard Street while they were on scene, but everything has reopened. The cause of the fire remains under investigation.
