The Mayday feature in the Command Module provides incident commanders with a structured, systematic approach to managing firefighter emergency situations by creating dedicated tracking sections, implementing protective restrictions on affected units and assignments, generating automatic Mayday-specific checklists, and maintaining comprehensive documentation of all Mayday-related actions. This critical safety feature ensures that personnel emergencies receive immediate attention, appropriate resources, and complete accountability throughout the Mayday incident lifecycle.
Mayday situations represent the highest-priority emergencies during fire and rescue operations, requiring immediate command attention and systematic management to ensure the safety of endangered personnel. The Mayday feature transforms the command board to prioritize and track these life-threatening emergencies while maintaining documentation for post-incident review.

Q: Why can't I move or edit a unit that's highlighted in red?
A: Units highlighted in red are declared Mayday units and are intentionally locked to prevent accidental modification during the emergency. This protective restriction ensures Mayday units remain tracked in their last known location and cannot be inadvertently moved or altered during rescue operations.
Q: Can I delete an assignment that has a Mayday unit in it?
A: No. Assignments containing Mayday units are protected and cannot be edited or deleted until the Mayday is resolved. This ensures the assignment context and last known location of Mayday units are preserved throughout the emergency.
Q: What's the difference between the status updates (Crew, Self-Rescued, Rescued, Transported) and the removal options (No Issue, Remove)?
A: Status updates provide progress information but keep the unit in the Mayday section for continued tracking. Removal options ("No Issue" and "Remove") actually remove the unit from Mayday tracking and return it to unassigned units, indicating the emergency is resolved for that unit.
Q: Can I add units to assignments that already have Mayday units in them?
A: Yes. While the Mayday units themselves are locked, you can still assign additional units to assignments containing Mayday units. This allows you to send rescue resources to the location where Mayday personnel are known to be.
Q: What happens if I accidentally cancel a Mayday instead of completing it?
A: Both "Cancel Mayday" and "Complete Mayday" have the same functional result—they close the Mayday tracking and return the command board to normal operations. The distinction is primarily for documentation purposes in the Log Section. If you need to reactivate Mayday tracking, you would need to activate the Mayday feature again.
Q: How do I know which checklist items will appear when I activate a Mayday?
A: Mayday checklist items are configured in Command Setup in the Mayday section. Review and configure these checklist items during pre-incident planning to ensure appropriate tasks are included. Contact your system administrator if Mayday checklist configuration needs to be modified.
