What is a potential hazard in elevator door zones?

Uncontrolled door operations present a significant hazard in elevator door zones because they can lead to unexpected movements of the doors, which might not open or close as intended. This unpredictability increases the risk of injury to passengers, as they may become caught in the doors if they operate erratically. Additionally, if the doors do not follow the safety protocols, such as the required sensing capability to detect obstructions, the likelihood of accidents in the door zones escalates.

Understanding this can help ensure that elevator systems are regularly inspected and maintained, focusing on the mechanisms that control door movements, to eliminate or reduce the risks associated with uncontrolled door operations.
