@Spxtz for a second floor tenement you're going to have a pretty hefty set of ladders. Storing those is quite an undertaking.
I was in a second floor tenement for a few years in the West End and felt some sense of ease after I got a key to get roof access - in most of Glasgow you can walk from tenement to tenement on the roofs in a gully in the centre which is why seagulls love them so much. So if you couldn't get down the stairs you can always get on the roof and move a safe distance away.
Its a lot more costly but some tenements have also had metal stairs installed which might be a move some factors push for given the last few fires that have sadly happened in the city.
