When should door safety straps be placed across the door?

The placement of door safety straps across the door is crucial for ensuring the safety of passengers and crew when the aircraft is not connected to a jet bridge or air stairs. When the jet bridge or air stairs are not in position, there is a risk of individuals approaching or entering the area near the open door, which could lead to accidents or unauthorized access. Therefore, using the safety straps in this situation creates a barrier, effectively communicating to personnel that the door should remain closed and secure until the aircraft is ready for boarding or deplaning.

This practice is not necessary when the cabin door is closed, during boarding, or specifically when a flight is delayed. In those cases, other safety protocols are typically in place to manage the flow of passengers and maintain overall safety. Thus, placing the straps when the jet bridge or air stairs are absent is the correct and most effective measure to enhance safety during ground operations.
