How often must an EPIRB on an offshore drilling unit be tested?

• A. Once every month.
• B. Every six months.
• C. Weekly.
• D. Quarterly.

Answer: (A)

Regular readiness of an EPIRB relies on a monthly check. The monthly self-test confirms the beacon’s electronics, battery condition, and antenna are all functioning and that the unit would transmit if it were needed. This test is designed to avoid sending a real distress signal; it simply verifies that the beacon is capable of operating. If the self-test shows any fault, the unit should be serviced or the battery replaced before use. While annual servicing and battery-life considerations are part of overall maintenance, monthly verification is the practical interval to keep offshore equipment reliably ready. Other intervals—weekly, quarterly, or every six months—do not align with standard maintenance practice for ensuring immediate operability.
