Yet people still die in apartment building fires, usually because they panic when there is a fire in another apartment, leave their apartment, and suffocate to the smoke. And then there are cases where the regulation has failed / not been followed, and the whole building burns down despite best efforts from firefighters.

I've seen all these things happen, even though I live in EU country with strict regulations. I sure sleep better knowing that my apartment has entrance directly to outdoor corridor, and a ladder I can climb down from my balcony if the corridor is somehow blocked. I would never move into a modern apartment building where only escape is through indoor corridors.
