When a mayday is called, what else must be requested by command?

When a mayday is called, it is essential for command to request additional alarms. This is because a mayday indicates that a firefighter is lost, trapped, or in immediate danger, and it typically requires a prompt and coordinated response from multiple teams. By calling for additional alarms, command ensures that more resources are dispatched quickly to handle the emergency situation effectively. This can include additional firefighters, specialized rescue teams, and equipment that may be necessary to locate and assist the endangered personnel.

Requesting additional alarms helps to establish an effective incident command structure to manage the growing complexity of the situation, ensuring that adequate personnel and resources are available to execute a safe and efficient rescue operation.
