===================
Safety, Urgency, and Distress Calls:
 
Maritime monitors often encounter transmissions that are preceded by
special urgency signals.  Here are the definitions of the terms used when
unusual circumstances dictate.
 
DISTRESS: "MAYDAY", spoken three times, indicates that a vessel is
threatened by grave and imminent danger and commands absolute priority over
all other communications.
 
URGENCY: "PAN PAN", spoken three times, indicates the safety of a vessel
or a person is in jeopardy, e.g. an urgent radio-medical message, "man
overboard" or "engine failed, request tow".  Only distress calls command a
higher priority.
 
SAFETY: "SECURITE" (pronounced SAY-CURE-E-TAY) spoken three times, indicates
a message that concerns the safety of navigation or an important weather
warning.
 
Radiotelephone "Silence Periods" occur on the International Calling and
Distress Frequencies commencing on the hour and half hour for a duration
of three minutes.  All stations MUST CEASE transmission on 2182, 4125, 6215,
8291, 12290, and 16420 kHz and listen for any distress calls.-
