Summary
A saturation diver suffered chemical burns after exposure to chemically treated seawater while disconnecting a pigging/flushing hose during decommissioning. The flash identifies uncertainty over flushing and absent engineered barriers. Lessons address understanding pipeline contents, hazard analysis, amended procedures, valve isolation and securing, and reducing exposure through local valves.
