When is an elevator car door considered closed?

An elevator car door is considered closed when the space between the door edge and the jamb is no more than 2 inches. This definition is crucial for ensuring safety and proper operation within elevator systems. A gap of 2 inches or less indicates that the door has effectively engaged with its frame and is functioning as intended, helping to prevent accidents or malfunctions that may occur if the door does not properly seal.

Additionally, according to established safety standards, maintaining this specification ensures that users cannot inadvertently reach through a larger gap, which could lead to injuries. Properly closing doors are imperative to secure the elevator’s functionality, as they are designed to maintain safety by preventing the accidental opening of doors while the elevator is in transit.

The other options, while indicating potential concerns regarding the positioning of the doors, do not align with the established criteria for considering an elevator door fully closed in operational standards. For example, a fully closed door without gaps is ideal, but if there is any space greater than defined limits, it does not meet the necessary safety threshold. Thus, measuring the door against the established maximum gap of 2 inches is the correct approach to determining its closed status.
