🔍 Key Concepts

• EPIRB (Emergency Position Indicating Radio Beacon) testing requirements on MODUs • SART (Search and Rescue Transponder) testing and maintenance intervals • Specific testing intervals vs. battery replacement/servicing intervals in SOLAS/46 CFR for lifesaving appliances

💭 Think About

• Think about how often critical emergency locating equipment should be verified to work without creating unnecessary battery drain. • Consider whether the exam is asking about a test interval (operational check) or a maintenance/servicing interval (like hydrostatic release or battery replacement). • Compare this required test interval with other routine checks on lifesaving appliances aboard a MODU (e.g., are they usually weekly, monthly, or longer?).

✅ Before You Answer

• Verify that the question is about testing frequency, not servicing or replacement. • Confirm which interval is explicitly stated in current SOLAS / 46 CFR requirements for EPIRB/SART testing on MODUs. • Eliminate any options that would likely either over‑drain batteries or be too infrequent for critical distress-alert equipment.
