Which action is not appropriate when a passenger refuses to comply with safety directives?

The action of physically restraining a passenger is not appropriate when a passenger refuses to comply with safety directives. This is due to various reasons, including legal implications, the potential for escalation of a situation, and the need to maintain a safe environment for all passengers and crew members. Restraining a passenger could lead to injury or harm, both to the individual being restrained and surrounding individuals, as well as creating a chaotic situation on board.

In contrast, notifying the captain is a standard procedure to ensure that the situation is handled by someone in authority who can make decisions regarding safety protocols. Attempting to reason with the passenger is a proactive approach that can sometimes resolve misunderstandings or miscommunications peacefully. Documenting the event is crucial for maintaining records of incidents that may need to be referenced later for safety reviews, legal matters, or training purposes. Each of these appropriate actions emphasizes communication, safety, and proper protocol, while physical restraint tends to contradict those principles and can exacerbate conflicts rather than resolve them.
