Sec. 80.329 Safety signals and messages.
(a) The safety signal indicates that the station is about to transmit a
message concerning the safety of navigation or giving important
meteorological warnings.
(b) In radiotelegraphy, the safety signal consists of three repetitions of
the group TTT, sent with the individual letters of each group, and the
successive groups clearly separated from each other. It must be sent before
the call.
(c) In radiotelephony, the safety signal consists of the word SECURITE,
pronounced as in French, spoken three times and transmitted before the call.
(d) The safety signal and call must be sent on one of the international
distress frequencies (2182 kHz or 156.8 MHz radiotelephone). Stations which
cannot transmit on a distress frequency may use any other available
frequency on which attention might be attracted.
(e) The safety signal and call must be followed by the safety message. Where
practicable, the safety message should be sent on a working frequency, and a
suitable announcement to this effect must be made at the end of the call.
(f) Messages about meteorological warnings, of cyclones, dangerous ice,
dangerous wrecks, or any other imminent danger to marine navigation must be
preceded by the safety signal.
(g) Stations hearing the safety signal must not make any transmission likely
to interfere with the message.
