Fire crews were called to a building in the 300 block of West Dayton Street just before midnight on Wednesday for an alarm. Several residents met firefighters outside the building and reported a fire.
A dryer and its contents were found on fire in a laundry room. A single sprinkler was keeping the flames from extending to the rest of the room.
Crews used an extinguisher to take out the remaining flames, and crews remained on scene to ventilate the building and stop the water flowing from the sprinkler.
No injuries were reported.
