Summary
Two diving incidents within 24 hours involved depleted bail-out bottles and leaking high-pressure content gauge hoses. Examination identified cuts and bending-related damage near ferrule connectors despite bend restrictors and regular checks. The flash compares hose constructions and notes that annual replacement of one type may be required, depending on usage.
