What information must be provided after a MAYDAY transmission?

• A. Location, Unit ID, Name/designation, Air/assignment, Resources needed (LUNAR model).
• B. Time of day and weather conditions.
• C. Destination and estimated arrival time.
• D. Number of crew and vehicle type.

Answer: (A)

When a firefighter issues a MAYDAY, the most critical need is to quickly provide information that lets rescuers locate and assist them without delay. The best information to share after the call is the location, the unit identification, the responder’s name or designation, the air status or current assignment, and the resources needed.

Location tells the incident command exactly where the team is, inside a structure or in a specific area, so rescuers can pinpoint them. Unit identification distinguishes which crew is in trouble, which is essential when many teams are operating. The name or designation helps with personal recognition and accountability among responders who may be in close proximity or moving through the scene. Air status is vital because it indicates how long the team can continue operating before air supplies run low, guiding urgency and rescue sequencing. The assignment communicates what the team is currently doing or where they are positioned within the incident plan, aiding coordination. Finally, stating the resources needed requests the specific support required to complete the rescue, such as additional personnel, RIC, extra air cylinders, or specialized tools.

This set of information is prioritized over less immediate details like time of day or weather, which, while useful for broader planning, do not drive the immediate rescue decisions. Details about destination or ETA, or just the number of crew and vehicle type, don’t provide the actionable, situation-critical data needed to locate and save the distressed firefighter.
