The Australian Maritime Safety Authority (AMSA) draws attention to the importance of regular maintenance of float-free Emergency Position Indicating Radio Beacons (EPIRBs) to ensure they function properly in an emergency, especially after two years of use.
According to AMSA, float-free EPIRBs automatically activate during maritime emergencies. Stored in a float-free bracket, these water-activated devices deploy when a vessel capsizes at depths of 1–4 meters. The EPIRB, equipped with a hydrostatic release unit (HRU), surfaces and transmits a distress signal to alert rescuers of the vessel’s location.
To ensure EPIRBs operate effectively, attention must be given to two key components:
– Battery: EPIRB batteries have a limited lifespan and require regular checks to ensure they are current and functional.
– Hydrostatic Release Unit (HRU): The HRU must be replaced within two years of installation, unless otherwise specified by the manufacturer. This unit is critical for the proper deployment of the EPIRB.
– Regular checks and adherence to manufacturer guidelines help guarantee the EPIRB’s readiness for life-saving action when needed.
