During a recent audit, a Member discovered significant non-conformances pertaining to the storage and maintenance of AED. 

What happened?

The consequences were potentially significant, and immediate re-assessment was undertaken of all such equipment at that member’s dive sites. AEDs should be available for immediate usage.

Our member’s audit process noted the following non-conformances:

Battery had been removed or fitted incorrectly

The battery had been removed or had been fitted incorrectly to the device. This was contrary to advice in the user manual for the item

pads on the AED were out of date

The pads on the AED were out of date

Our member considers this to be a significant issue. Inspection of other sites revealed that in some cases batteries were removed or detached from the units. Removing or detaching the batteries from these units will prevent the unit being used for an additional sixty seconds, and lessens the chances of survival for the patient.

Our Member took the following actions:

  • Confirmed that the battery was fitted in accordance with the manufacturer’s instructions.
  • Confirmed that all equipment associated with the AED was ‘in-date’.
  • Tested the readiness of AED in accordance with the manufacturer’s instructions.
  • Appropriately trained personnel conducted a familiarization session on use of the AED with all of the crew.
  • Ensured that the maintenance of the AED was added to the appropriate planned maintenance system.
