We had a false alarm go off in the building where I work last week. The elevators automatically shut down forcing the use of the fire escapes. The building is 22 floors. I was lucky in that I’d just taken the elevator to the first floor to step outside on a break. When they finally let us back in, I wondered what someone with mobility issues is expected to do had the building been on fire. Just die? Have a kind soul carry them? With most people wfh at least a couple of days per week, this seems really dangerous for anyone who might get stranded.
I saw one place that had a dedicated device in the stairway that was meant to help carry wheelchair bound people down the stairs.

…we used unpowered dollies of similar design for moving large appliances back when i was a groundskeeper…
