What is a MAYDAY signal?

• A. A routine status update from the incident commander.
• B. A distress signal used to indicate a life-threatening emergency.
• C. A request to pause operations for safety.
• D. A notification to switch to a secondary channel.

Answer: (B)

A MAYDAY is the radio distress call firefighters use to indicate a life-threatening emergency and the immediate need for assistance. It signals that someone on scene is in grave danger and requires rapid rescue. When a Mayday is declared, expected actions shift from normal operations to emergency response: crews focus on locating and extracting the person, maintain radio discipline, and switch to emergency traffic as needed to coordinate a rapid intervention. The person reporting the Mayday typically provides or is assisted to provide their location, unit identity, and the nature of the danger so responders can prioritize and tailor the rescue.

This signal is not a routine status update, a request to pause operations, or simply a command to switch channels; it is a urgent plea for immediate help that triggers the most urgent safety and rescue procedures on the fireground.
