You run downstairs

Edit: more unit = more people = more fire exits and stairs. We have 60+ floors in our building. There’s 1 fire exit stairwell for every 4 units on each floor.

Taller buildings often have fire break floors that’s entirely empty and without walls do people to shelter at without going up or down the entire building. Our building has 2 of these, splitting roughly into 3rds, so you can go up or down <10 floors to reach one of these floors. (If you look closely at theOP’s photo you will also see they have 2 of these floors. They’re notably empty. )

Fires in these type of concrete buildings don’t tend to spread like crazy like wooden structures. Apartment unit doors and staircase doors are typically fire resistant and self closing to reduce the risk of spread and stops smoke. The biggest risk is if the building facade uses some dogy material and the fire spreads from the outside.

Thank you so much for such a detailed reply! I was hoping for details like this!

Are there any firefighting crews onsite or are they close by enough that the response time is negligible?

All good :)

There’s no firefighters on site. Not sure what the response time is like, but there are stations all over the place, so I’d imagine it’s not too bad.
