Summary
A thermal cup returned from saturation through a medical airlock separated violently from its plastic base at surface pressure, causing minor bruising to an assistant life support technician. The flash records the diver’s assumption about pressure differential and recommends drilling such vessels or prohibiting non-venting thermal vessels in saturation chambers.
