What are wheelchair-bound people to do when a building alarm disables elevators? (lemmy.sdf.org)

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.

One thing I haven't seen in the thread yet, is that there ARE elevators which are intended for use during fire-related evacuations. I've been in buildings where signs by the elevators make it known that during evacuations you are SUPPOSED to use them.

I don't know the specifics, but I would assume these have self-monitoring sensors to allow the elevator control system to determine whether it is affected by whatever is going on.

I suspect the way they work also changes, instead of prioritizing getting around different floors, the computer would start shuttling them up and down specifically to get people from each floor down to ground level. No-one already in the elevator gets to pick what floor they're going to.

Modern buildings are constructed in a way that significantly slows the spread of a fire, and I would assume that the machinery and shaft of evacuation elevators, doubly so.

And same as any elevator, they are built using a level of redundancy that means several cables can fail without issue, as well as emergency brakes that arrest the fall of the cabin should the worst occur.
