A fire broke out shortly before noon in the 3000 block of Claremont Ave.
That’s on the west side between Tekoppel and Schrader.
Officials say they put out the fire with the help of the building’s sprinkler system, and everyone was back to work in about an hour.
They say this is the second time recently that a sprinkler system has helped stop a fire from spreading.
Just last week, there was a fire at the former Whirlpool plant. Fire officials used it as an opportunity to share the importance of a sprinkler system.
