Root Cause

Elevator shafts act as chimneys, drawing smoke and fire upward; power failure can trap occupants; fire-rated elevator lobbies are rare; most fire codes prohibit elevator use during fire.

Workarounds

  1. 90% success Use designated fire escape stairs. If mobility-impaired, proceed to an area of refuge (e.g., fire-rated stair landing) and call 911 with your location; fire crews are trained to assist.

Dead Ends

Common approaches that don't work:

  1. 92% fail

    Fire can cut power at any moment, trapping the user; smoke may enter the car before doors close; elevator recall (firefighter mode) may override manual control.

  2. 98% fail

    Rooftop helipads are rare and require fire department approval; most building roofs are not designed for landing; smoke and heat rise, making roof dangerous.

  3. 85% fail

    Doors will eventually close due to door-hold timer; smoke can still enter through gaps; this violates elevator safety interlocks.
