What must an airport do immediately following an incident before contacting TSA?

The immediate step an airport must take following an incident is to evaluate the situation and initiate the necessary response protocols. This includes assessing the severity of the incident, ensuring safety for all personnel and passengers, determining the appropriate actions that need to be taken, and establishing communication with relevant authorities.

Evaluating the incident helps in understanding the immediate risks involved, while initiating an action plan sets the groundwork for further steps, such as informing emergency services or contacting TSA. Thus, this response ensures that the airport can efficiently manage the situation and relay critical information to necessary agencies without unnecessary delay or confusion, maintaining safety and security throughout the process.
