What term is used for an urgent message that takes precedence over all other radio communications?

The term "Emergency Traffic" is used to signal an urgent message that must take precedence over all other radio communications. This designation is crucial in emergency situations where the safety of personnel and the effectiveness of operations depend on immediate and clear communication. When an emergency situation arises, it is essential for responding units to have clear access to vital information without interference from routine transmissions.

By declaring "Emergency Traffic," the user effectively halts non-critical communication and allows space for information that can significantly impact decision-making and operational response. This protocol helps ensure that responders are aware of hazardous conditions, changes in the situation, or urgent updates that require immediate action. In firefighting and emergency response, where timing is often critical, the ability to prioritize communications significantly enhances the effectiveness and safety of the response effort.
