Summary
During subsea diving, taut wire recovery pulled two divers from the seabed to 18 m above their maximum excursion depth, risking pressure-induced injuries. Both reported well after transfer and tests. The flash identifies communication failures and missing lift planning, and describes revised diver-clearance requirements, repeat-back instructions and stop-work measures.
