Application of Hazard-Based Risk Assessment to Safety Test Items in Consumer Product Safety Standards

Le résumé fourni par la source

Recent product safety management systems have been shifting from compliance-based approaches toward risk assessment approaches that consider the severity and probability of harm to consumers. However, the current consumer product safety framework in Korea primarily relies on predefined defect levels linked to individual safety test items, which may limit the ability to systematically explain the actual level of product risk. This study applies a hazard-based risk assessment approach to safety test items specified in consumer product safety standards and examines their relationship with the existing defect-level classification system. A total of 1,183 safety test items were reclassified into hazard groups based on the Safety Gate: Risk Assessment Guidelines(SAGA) hazard taxonomy. A rule-based risk graph model derived from ISO/TR 14121-2 was applied to estimate risk levels based on severity, exposure, probability, and avoidance parameters. The results show that the test items can be structured into eight hazard groups, with risk levels distributed as High(21.1%), Medium(38.3%), and Low(40.6%). The agreement between the existing defect-level classification and the risk assessment results yielded a Cohen’s kappa value of 0.823, indicating a high level of consistency. The proposed approach provides a hazard-oriented analytical framework that can complement the existing test-item-based conformity assessment system and support regulatory decision-making for consumer product safety.
