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.
When I worked in a high rise we had floor fire wardens per office, and we had to have a plan on who would carry injured or otherwise immobile people down the stairs. I had an ankle surgery at one point and had a designated carrier, and a secondary for when they were out of office.
