Summary
A vessel welder preparing to install steel shelves was stopped before welding onto a fuel tank beneath the deck. The flash identifies planning, communication, responsibility and signage failures despite an issued permit. Actions included marking prohibited welding areas, using general arrangement drawings for permit coordination, and clarifying permit issuers’ and area authorities’ responsibilities.
