3.6.3 Safety Communications Safety Signal In radiotelephone, the safety signal is the word SECURITE spoken three times. It is sent before the call. The safety signal indicates that the station calling is about to transmit a message containing an important navigational or meteorological warning or information. Priority The safety signal has priority over all other communications except distress and urgency. All stations hearing the safety signal shall continue to listen on the frequency on which the signal has been transmitted. They may stop listening when they are satisfied that the message is of no interest to them. All stations that hear the safety signal must take care not to interfere with the message which follows it. No transmission shall be made that may interfere with these messages. Safety Call and Message Procedure The safety signal call may be sent at any time on the international distress frequency of 156.800 MHz (Channel 16). It shall be sent only on the authority of the person in command of the station. The safety message that follows the call is sent on a suitable working frequency such as 156.300 MHz (Channel 6). A short announcement giving the working channel and the area affected is made at the end of the safety call. In the Maritime Mobile Service, safety calls and messages are normally addressed to ALL STATIONS, In some cases, however, they may be addressed to a particular station, such as a Coast Guard radio station. If the message is addressed to a Coast Guard station, it would be sent on a Coast Guard or Coastal Radio working frequency. Meteorological and navigational warning messages that contain information on imminent danger to marine navigation must be transmitted without delay, Example:
