Check service intervals for float-free EPIRBs
Float-free EPIRBs are water-activated distress beacons fitted in a float-free bracket. They are designed to activate when a vessel capsizes to a depth of one-to-four metres. Once submerged, a hydrostatic release unit (HRU) opens to release the EPIRB unit, which can then float to the surface and transmit a distress signal.
Regularly check your HRU and EPIRB battery to ensure your float-free EPIRB will activate properly in an emergency and stays compliant with safety regulations.
A simple checklist includes:
- Check the EPIRB battery: Ensure it’s in date and functional. An EPIRB battery has a fixed lifetime and should be regularly checked to ensure it transmits properly in an emergency. Generally, a battery will last from 5-10 years.
- Replace the HRU: Every two years (or as per manufacturer’s instructions).
- Failure to replace the HRU and release rod after two years may result in the EPIRB not deploying correctly in an emergency. Each brand of float-free EPIRB has a specific EPIRB HRU model and replacement kit approved for installation, refer to the manufacturer instructions.
- A life raft HRU, or reusable HRU, are not approved to be installed in a float-free EPIRB.
- Once a float-free EPIRB has been activated, the release rod is cut in half in order to release the EPIRB to float free. It is important to ensure you replace the HRU and release rods after it has been used.

All Australian EPIRBs must be registered with AMSA. Registration is valid for two years after the date of issue and must be renewed before its expiry date. Read more about why it is important to register your beacon.
