(14) Section 3040(b)(5). An emergency stop switch (switches) conforming to Section 3040(b)(5) shall be provided to stop operation of the lift, the door operation and transfer device operation. The emergency stop switch shall be located in the car adjacent to each entrance in a position that shall be accessible to a person standing at the floor adjacent to the car entrance. If a permanently mounted transfer device, located at the landing, blocks the entrance to the car, an emergency stop switch shall be located at that landing in a position accessible to a person standing near that landing in addition to the emergency stop switch in the car.

(A) A switch shall be mounted adjacent to each landing entrance that will stop the operation of power operated doors and the transfer device at that landing.
