Assuming you can even open the windows there's a chance in a building like that that you end up in a hallway. A largely wooden interior with paper with ignited gas fumes is going to make the building a fucking tinderbox too so you aren't going to have time to come up with a plan.
Fires are really horrifying and a lot of people underestimate them, I'm sure a lot of the dead were fucked the second it ignited with no real hope of being saved.
