The Urgency signal concerning the safety of a ship, aircraft or person shall be sent only on the authority of

• A. Master of ship
• B. Either Master of ship or person responsible for mobile station
• C. Person responsible for mobile station
• D. The station's operator

Answer: (B)

Urgency signals are used to alert others to safety concerns when there isn’t immediate danger, and they must be issued only by someone who has the authority over the vessel’s radio operations. That authority lies with the Master of the ship or the person responsible for the mobile station. The Master has the ultimate on-board authority, while the designated radio operator can authorize an urgent transmission on the ship’s behalf when empowered. This ensures urgent safety communications are raised only by someone legitimately in charge of the ship’s communications. The station’s operator alone isn’t automatically authorized to issue an urgency call without that on-board authority, and the wording allows either the Master or the person responsible for the mobile station to authorize.
