Talk-around communication being used only as a last resort aligns with standard communication protocols in many operational settings, particularly in transportation and emergency services. This practice is instituted to ensure that standard communication channels are utilized first, which generally provide clearer and more reliable information.

The importance of using the primary communication methods first is due to the structured approach in emergency response and operations management, where clarity and directness are crucial for safety and efficiency. Talk-around communication, which often indicates a more informal or secondary means of communicating (such as communicating directly without the aid of a dispatcher), can potentially lead to misunderstandings or a lack of coordination if used excessively.

By reserving talk-around communication for critical scenarios, teams can ensure that everyone is on the same page and that information is disseminated in a structured manner, reducing risks associated with miscommunication. Thus, this answer encapsulates the reasoning behind prioritizing formal communication channels.
