At what intervals must an EPIRB's power source be replaced?

The correct interval for replacing an EPIRB's (Emergency Position Indicating Radio Beacon) power source is not to exceed 12 months. This requirement is in place to ensure that the EPIRB remains functional and can effectively signal for help in an emergency situation. The reliability of the power source is crucial, as the EPIRB must be able to transmit distress signals accurately when needed.

Regularly replacing the power source, as dictated by the 12-month standard, helps to mitigate issues related to battery degradation or depletion, which can occur over time even if the device is not in active use. This standard aligns with manufacturer recommendations and regulatory guidelines, promoting safety and preparedness for maritime operations.

Intervals shorter than 12 months may result in unnecessary costs and maintenance, while longer intervals could jeopardize the device’s readiness and performance during emergencies. Thus, the 12-month power source replacement schedule strikes a balance between operational reliability and practical maintenance needs.
