In an emergency, which device should be activated immediately to alert authorities?

• A. GPS
• B. EPIRB
• C. VHF radio
• D. Searchlight

Answer: (B)

In an emergency at sea, the device that should be activated immediately to alert authorities is a dedicated distress beacon (EPIRB). This purpose-built device is designed to automatically broadcast a distress signal to satellites and rescue authorities, quickly initiating a coordinated response. It works by emitting a 406 MHz distress signal that is picked up by the international Cospas-Sarsat satellite system, which then relays the alert to the appropriate rescue coordination center. If the beacon has GPS, it can also transmit your precise location, speeding the rescue effort. Why not rely on GPS alone? GPS gives location details to your equipment, but it doesn’t initiate contact with rescue services. A VHF radio can be used for voice communication, but it requires someone to be listening and is limited by range and availability. A searchlight helps visibility, not distress signaling. So, activate the EPIRB right away, keep it enabled, ensure it’s registered and functioning, and understand that it is the primary means to alert authorities in an emergency.
