Summary
A chamber operator began venting an outer lock while a diver remained inside following surface decompression diving. Recompression and treatment for omitted decompression followed; the diver remained asymptomatic. The flash examines assumptions, poor visibility and missing transfer checks, stressing diver signals and operator and supervisor verification before venting.
