Which radio terminology is used to report a firefighter is in trouble and requires immediate assistance?

• A. Emergency traffic
• B. Fire fighter requesting assistance
• C. Signal 102
• D. Mayday

Answer: (D)

Mayday is the established radio distress signal used to report a firefighter who is in trouble and requires immediate assistance. When a firefighter cannot safely manage a situation—such as becoming trapped, running out of air, or facing imminent danger—the Mayday call alerts everyone on scene and at the command post that immediate rescue is needed. This triggers urgent responses like declaring emergency traffic to clear the channel for critical messages, activating a Rapid Intervention Crew, and prioritizing the rescue operation. The call should be clear and concise, typically including the word Mayday, the firefighter’s location, unit, and a brief description of the emergency, along with any relevant details like air status and hazards if possible. Other terms either describe procedures or are department-specific codes and do not universally signal a life-threatening situation.
