Summary
A diver’s cutting torch leaked oxygen on the seabed at around 27 msw, despite showing no leak during surface testing. The flash attributes this to the valve housing fit under ambient pressure at depth. Recommendations cover topside leak testing, housing seating and set-screw adjustment, vendor communication and inspection documentation.
