In SUDOT commands, how is trouble indicated?

In SUDOT commands, trouble is indicated by a continuous blast. The use of a continuous blast serves as a clear and urgent signal that there is an immediate issue that needs attention. This method of communication is essential in high-stress environments, such as rescue operations, where quick and unambiguous cues can facilitate rapid responses from team members.

The continuous nature of the blast ensures that it stands out from other commands or signals, which might have distinct patterns, such as one or two blasts for different instructions. This distinction is crucial to avoid any confusion during critical moments, ensuring that all team members recognize that they need to stop their current actions and focus on the potential trouble indicated by the sustained sound. This practice underscores the importance of effective communication and safety protocols in rescue scenarios.
