@LunaDragofelis on a different note: #Buildingcodes in terms of #FireSafety do get updated and more stringent, with #accessibility and #safety first in mind, requiring redundant safe exits even for upper floors and having strict requirements for #FireElevators in places where mobility-disabled or otherwise immobile people are to be expected like hospitals, schools and caretaking facilities.

• So modern buildings have like external escape doors and -ramps to comply with said requirements.

@LunaDragofelis Those #FireElevators usually can be distinguished by a second set of key switches on the inside [for use by #firefighters only!] that override the door safety and allow opening/closing the door that way and disregard the light sensor barriers.

• Which are the prime reason one shouldn't use #elevators in a #fire, because #smoke will render them useless and potentially force a stop in a smoke-filled floor.

@LunaDragofelis well, #FireElevators aka. #Elevators that can be safely used during fires DO EXIST.

• The problem isn't even power for the most part, as Elevators for the most part are designed to slowly descent upon max load and otherwise their counterweights raise them slowly.
  • the problem is that #BuildingCodes and #FireSafety legislation don't mandate them outside of extremely tall buildings like TV Towers with Public Visitor Platforms / Restaurants.
