10 firefighters are listed in in stable condition following the blaze at an abandoned dry cleaners, where a wall collapsed as crews fought the fire at the one-story building, MyFoxChicago.com reports.
Dozens of firefighters sifted through the rubble to find their comrades, and then rushed them to nearby hospitals.
The fire started at about 7 a.m. local time and a “mayday” call went out when the wall collapsed. Ten ambulances rushed to the scene.
The blaze occurred on the 100th anniversary of the Union Stockyards fire that claimed the lives of 21 Chicago firefighters in 1910. In all, 24 men in that fire in the meatpacking operation at a Morris & Co. plant.
