🔍 Key Concepts

• Meaning of the safety device abbreviation EPIRB used on SOLAS vessels and other commercial ships • The purpose of an EPIRB in distress situations (what it sends and to whom) • Difference between radar and radio in maritime communications

💭 Think About

• Think about what an EPIRB actually does when a vessel is in distress—what kind of signal does it transmit? • Ask yourself: Is this device mainly connected with radar detection, or with radio signals transmitted to satellites and rescue coordination centers? • Look carefully at each word in the options and decide which combination best matches the real-life function of this emergency device.

✅ Before You Answer

• Verify that the P stands for a word that describes what the beacon provides about the vessel to rescuers. • Check whether R is more accurately associated with Radio or Radar given how distress alerts are normally sent. • Confirm that the full phrase you choose is a standard, internationally recognized term used in SOLAS and USCG materials.
