Which signal is used to indicate an urgent safety concern without requiring immediate assistance?

• A. Distress call.
• B. Urgency signal indicating a safety concern not requiring immediate assistance.
• C. End of transmission.
• D. A routine call.

Answer: (B)

An urgent safety signal is used when there’s a safety concern that needs attention but no immediate danger. In radiocommunication, this level is indicated by Pan-Pan, spoken three times, to alert others that assistance may be needed soon but there isn’t an imminent threat. This distinguishes it from a distress call (Mayday), which means grave danger requiring immediate help, and from routine or end-of-transmission signals, which don’t convey any safety issue. So the signal that matches an urgent safety concern without requiring immediate assistance is the Pan-Pan urgency signal.
