As a volunteer fire fighter my advice is please leave immediately when alarm sounds. A high rise building, or a multilevel building such as large office building are what even we fear, because things can happen between you and the exit, such as open flame, fallen ceilings, and blocked passages. If we run out of compressed air, we die. You don't have compressed air. If smoke comes between you and exit, you die. Watch this to see how quick a fire can spread. Remember, people are not killed by fire, but by smoke. https://youtu.be/ezJ6SorlpJo
