The trouble with ladders from the outside is it allows folks other than rescuers (read, "burglars") get up to the higher windows.
On the other hand, I've thought about escape from upstairs a lot, and even bought one of those chain ladders but brought it back to the store.
First thing they tell you in the instructions is not to use it in a window where there's another window right below yours because the support legs which hold it away from the wall will break the window below you, swing toward the wall, and therefore make footing difficult.
Humph. Most windows are one above the other, and this is so in my second-floor apartment. Let me know if you find a dwelling with staggered windows.
Also could not use it off the balcony because there's no wall support below it for those sticking-out legs I mentioned.
Best thing for me, given the limited storage space and the measurements involved, would be a thirteen or fourteen foot "straight" ladder I could keep upstairs and drop down --but where to find one? I was seriously thinking about picking up an aluminum extension ladder and cutting off the 13ft needed, which would give me two ladders, but once again, storage space.
There is a rather large juniper bush under my bedroom window, and while I'm still looking for something better, I suppose I could throw some blankets down on it, then try to jump for it.
I'm too infirm to climb down a knotted rope, so that's kinda out, too.
I do keep fire extinguishers in every room but the bathroom.
What to do, what to do?
