Summary
A COBRA contents gauge detached while a diver vented the unit before charging in a bell hangar. Examination attributed thread failure to dynamic damage, likely from impacts during use. Actions included gauge inspection and replacement, monthly fitting-integrity checks, third-party examination and serialisation to improve traceability.
