5. If the elevator car is located at a level of more than ± 600mm to the nearest landing floor, then don’t release the passenger. Rescue works should be carried out by a lift technician as there is the danger that such rescue works may result in the risk of a fatal accident of the trapped passengers falling back into the lift shaft. If the elevator car is not level to safely bring the passengers out then sometimes it is advised to open the door approximately only about 200mm to allow fresh air or light into lift car to make the passengers feel more comfortable while waiting for the lift technician to arrive. The lift technician is trained to manually bring the lift to the nearest landing floor level by slowly releasing the brake at the traction machine in the lift motor room. [NOTE: THIS IS OPERATION MUST ONLY BE DONE BY TRAINED LIFT TECHNICIAN]
