Summary
A saturation diver’s bailout bottle lost pressure through wall defects associated with internal corrosion. Similar bottles were quarantined and operations suspended. Moisture was identified as the primary factor, while third-party testing or unsuitable storage was suspected. The flash calls for improved servicing specifications, procedural assurance, receipt inspection, drying and sealing.
