1. When the elevator is in danger, call the police as soon as possible. First, use the intercom or emergency button in the elevator to call the police. If there is no response within 3 minutes, you can call the emergency contact number in the elevator or 110 or a family member or friend.

2. If the alarm is invalid, you can call for help intermittently or tap the elevator door. Do not open the elevator door with your hands, do not escape from the top of the elevator, and do not act excessively.

3. Keep your back and head close to the interior wall of the elevator in a straight line with your knees bent to stabilize your center of gravity and reduce injuries.
