Summary
A diver installing concrete mattresses was struck by a handling frame moved by swell-induced vessel motion. Protruding angle iron penetrated his helmet, and trapping caused bruising. The flash examines two-tier load behaviour, impaired visibility and missed hazards, describing protrusion removal, a safety stand-down and recommendations for weather assessment and safer deployment frames.
