What is the term for radio communication regarding evacuation or downed power lines?

The term used for radio communication that pertains to urgent matters such as evacuation orders or reporting downed power lines is "Emergency Traffic." This term specifically refers to messages that require immediate attention and action due to their critical nature, such as life safety concerns or urgent safety information that needs to be communicated quickly to ensure the safety of personnel and the public.

Emergency Traffic is prioritized communication on the radio network, ensuring that it bypasses routine communications to deliver essential and time-sensitive information. This is vital in emergency situations where seconds can make a significant difference, as it alerts responders and personnel to take immediate action based on the message conveyed.

Other terms listed may pertain to various aspects of incident management, but they do not specifically encapsulate the urgency or critical nature of messages that involve immediate actions like forced evacuations or notifications of hazardous conditions, which is the focus of Emergency Traffic.
