What safety signal call word is spoken three times, followed by the station call letters spoken three times, to announce a storm warning, danger to navigation, or special aid to navigation?

The call word "SECURITE" is used to convey important safety information concerning navigation hazards or warnings. When this call word is spoken three times, followed by the station call letters also spoken three times, it serves as a formal alert to mariners about potential dangers, such as storm warnings or other critical navigational aids.

Using "SECURITE" helps ensure that listeners prioritize the communication, which is especially crucial in maritime environments where safety is of utmost importance. By announcing potential hazards clearly, it allows operators to take necessary precautions to navigate safely. This protocol is part of the established maritime communication standards, emphasizing the significance of clear and repetitive messaging in emergency situations.
