This study presents a methodology that adopts a multi-criteria decision analysis (MCDA) approach to evaluate countries' performance in preventing industrial accidents, using accident records and combining three MCDA techniques (TOPSIS, Electre II, and CoCoSo) to create a robust ranking. Applied to OECD countries, the methodology provides valuable insights into countries' commitment to industrial accident prevention. It highlights the impact of European Union legislation, variations in the ranks of G7 economies, and identifies role models like Spain and Italy while shedding light on the neglect of regulations in developing countries like Hungary and Turkey. In a world where industrial accidents have far-reaching consequences, this study emphasizes the importance of sincerity and dedication in accident prevention efforts.
