Not necessarily - dying in badly ventilated staircases is a very common cause of death during fires in large buildings. During a mandatory fire safety training I was told that often it is better to stay in your room, close the door to the hallway (treat it as a fire barrier) and go to the window where the firefighters can come get you.
