What term signals the immediate need to clear the radio and transmit critical information?

• A. 10-99
• B. Emergency Traffic
• C. Signal 2
• D. Critical Alert

Answer: (B)

In firefighting radio communication, there is a need to preempt regular chatter when a message is truly urgent. The term Emergency Traffic is used to signal that the channel must be cleared immediately and given to the person with critical information to transmit. When this is declared, all units should stop nonessential transmissions and switch to listening so the urgent message can be heard clearly and acted on without delay. This phrase is used for life-safety updates or information that could affect how the incident is being managed, such as a firefighter in distress, rapidly changing conditions, or essential resource needs. After the critical information is conveyed, the channel returns to normal traffic as directed by the incident command or dispatcher. Other terms describe different situations or are not the standard flag for urgent, high-priority transmissions, so they don’t convey the same immediate need to free the radio for a crucial message.
