The safety measures for elevators include: 

1. Speed limiter: A speed limiter is a safety device used to monitor the operating speed of an elevator. When the operating speed of the elevator exceeds the safe range, the speed limiter will automatically brake to prevent the elevator from losing control. 

2. Safety clamp: A safety clamp is a safety device used to secure the elevator car and steel wire rope or chain. When the operating speed of the elevator exceeds the safe range, the safety clamp will automatically clamp the steel wire rope or chain to prevent the elevator from losing control. 

3. Emergency brake: An emergency brake is a safety device used to stop the operation of an elevator in emergency situations. When the elevator malfunctions or in other emergency situations, the emergency brake will automatically brake to prevent the elevator from continuing to operate. 

4. Door lock safety device: A door lock safety device is a safety device used to ensure that elevator doors remain closed during operation. When the elevator door is not fully closed, the door lock safety device will automatically brake to prevent the elevator from running. 

5. Emergency communication device: An emergency communication device is a safety device used to communicate with the outside world in emergency situations. When the elevator malfunctions or in other emergency situations, passengers can use emergency communication devices to contact the outside world for assistance. 

In addition to the above safety measures, elevators also need regular maintenance and inspection to ensure their safety and reliability. In addition, elevators also need to comply with relevant safety standards and regulations.
