Quantitative risk assessment of industrial accidents among fishermen in purse seine fisheries

The risk of industrial accidents among fishermen in purse seine fisheries was assessed through the analysis of 1,478 approved industrial accident insurance claims over the past five years. The impact of risk factors specified in these insurance documents on accident types was evaluated through a chi-square test applied to three categories of purse seine fisheries: coastal, small-scale, and large-scale. Risk assessment was performed using a Bayesian network based on the formal safety assessment proposed by the International Maritime Organization. Based on factors identified as significant by the chi-square test, a Bayesian network was constructed to assess the quantitative risk of major industrial accident types within each purse seine fishery category. Time of occurrence, work processes, and environmental causes were significant risk factors in coastal purse seine fisheries. In small-scale purse seine fisheries, accident types were significantly associated with environmental causes, with hull-related slips/bumps and gear-related hits/entrapments identified as the major risks. Large-scale purse seine fisheries were analyzed based on vessel type: main boats, light boats, and carriers. Main boats and carriers were significantly associated with work processes and environmental causes, while light boats showed significant associations with fishermen’s nationality, work processes, and environmental causes. Main boats had the highest risk during fishing, with hull-related slips/bumps and gear-related accidents as the major threats. Light boats posed a 34.68-fold higher risk to nationals compared to foreigners. Fishing presented a higher risk, though it was not significantly different from sailing or maintenance. Carriers were the most dangerous during catch unloading. Hull-relat-ed environmental causes were the major risk, significantly outweighing risks from fishing gear (20.70-fold), machinery (8.75-fold), and external causes (17.26-fold). This study provides a foundation for implementing risk mitigation strategies in purse seine fisheries by identifying key accident-causing factors and presenting quantitative risk assessments based on fishery category and vessel type.
