Division 2.3 The landings at the entrance and exit of the car must be equipped with landing doors of adequate mechanical resistance for the conditions of use envisaged.

An interlocking device must prevent during normal operation:

1. (a)

   starting movement of the car, whether or not deliberately activated, unless all landing doors are shut and locked;

2. (b)

   the opening of a landing door when the car is still moving and outside a prescribed landing zone.

However, all landing movements with the doors open shall be allowed in specified zones on condition that the levelling speed is controlled.
