CHICAGO (CBS) — Quick action by Chicago firefighters saved two people from a burning building in the Roseland neighborhood overnight.

The fire broke out just before 11:30 p.m. in a three-flat building in the 10800 block of South Calumet Avenue, fire officials said. About 50 firefighters were sent to the scene.

Firefighters rescued one man trapped on the second floor. He was taken to Roseland Community Hospital in critical condition as a result of smoke inhalation, fire officials said.

Another man also needed treatment for smoke inhalation and was taken to Roseland, where he was listed in stable condition, Fire Media Affairs spokeswoman Meg Alheim said.

The heat – even at the late-night hour when the blaze was raging – was especially challenging for firefighters.

“All the training we do helps out with these guys. Working under these conditions when it’s getting this hot out, it’s really tough,” Fire Battalion Chief Maria DeCaussin said at the scene.

The fire was out by just before midnight, she said.
