Follow the predetermined evacuation plan for the work area. Close doors after passing through. Do not lock doors or allow doors to lock. Locked doors could preclude return should the fire prevent exit. If smoke is encountered, crawl rather than walk.
Air is cooler and less toxic nearer the floor.
Never use an elevator. If smoke is present in a stairwell, do not enter the stairwell. Choose another route. After exiting, move at least 50 yards from the building. Be factual, calm, and brief.
