Dozens of people were forced into the cold early Friday morning after fire and smoke moved through a Crafton Heights apartment building.
Initial reports indicated that some people were trapped inside of the burning on Woodlow Street, but firefighters said everyone was able to make it out safely.
Officials said one woman was treated for breathing problems, but is expected to be OK.
"We did a complete search, broke into all the apartments if the doors weren't open. We searched each unit and it was a happy ending. No one was left in the building," Pittsburgh Fire Department deputy chief Dan Hennesy said.
There is no word on what caused the blaze. About 20 units inside the building were damaged.
