That setup killed some people in Chicago a year or so ago. They were descending a stairway but kept going down into thicker and thicker smoke, and couldn’t leave to try another stairwell once they were locked inside it. High rise buildings in the area have since changed their policies - for instance, many with electronic locks on those doors have set them to go unlocked during a fire.
