Distress Signals

• Know the conditions under which distress signals may be used, the various types, what action to take on receiving one, and your obligation to render assistance
• Correct use of pyrotechnics, EPIRBs and SARTs, including the circumstances appropriate to each — these are tested as distinct pieces of equipment with distinct purposes, not interchangeable

Communications Procedure

• Correct distress communications procedure, including the precise meaning and use of Mayday, Pan-Pan and Securité messages
• Emergency communication within the GMDSS regulations

Quick Self-Check

• What's the difference between a Mayday, a Pan-Pan and a Securité message?
• What's the practical difference between an EPIRB and a SART, and when would you use each?
• When are you obligated to render assistance to a vessel in distress, and does that obligation have limits?
