Which phrase indicates that a safety message is forthcoming?

The phrase "Securitie, Securite, Securite" is used in maritime communication to indicate that a safety message is about to be transmitted. This term is part of the international communication protocols specified by the International Telecommunication Union and is designed to alert listeners to pay attention to vital safety information concerning navigation, weather conditions, or other potential hazards.

Using "Securitie" before the actual safety message establishes a clear signal to all stations that the information being presented is of importance and is meant to enhance safety at sea. It helps ensure that the message is taken seriously and that those receiving the communication are prepared to act on the information provided.

In contrast, terms like "Emergency, Emergency, Emergency" signal a distress situation, requiring immediate assistance, while "Attention, Attention, Attention" is more general and does not specifically indicate that safety information is forthcoming. "Warning, Warning, Warning" suggests a cautionary message but is less formalized in maritime communication than "Securitie." Therefore, "Securitie" is the precise term used to denote that critical safety information is about to follow.
