Serious disaster issues represent a corporate management risk, making the establishment of a preventive framework more important than anything else. Safety and health management systems must function effectively not only through documentation but also through on-site operations and inspections. When an accident occurs, initial response, cause analysis, and engagement with relevant authorities proceed simultaneously. Criminal, administrative, and civil liability may arise concurrently, necessitating an integrated strategy. The LIN Serious Disaster Response Team provides comprehensive support ranging from prevention consulting to accident response.
