[Investigation and analysis of occupational disease risk assessment index system in the automotive repair industry].

To construct a risk assessment index system for occupational disease hazards in the automotive repair industry using the Delphi method, providing a scientific basis and systematic evaluation framework for occupational hazard management in this sector. In January 2024, an expert survey method was employed to identify occupational hazard risk indicators through in-depth expert discussions. A multidimensional and hierarchical assessment system was designed based on the two core elements of "comprehensive prevention-on-site hazards." The consultation results from 20 authoritative experts demonstrated that the expert authority coefficient (0.84), coordination coefficient (0.73), and reliability coefficient (0.83) all reached robust levels. The importance scores of the indicators (ranging from 3.47 to 5.59 points) exhibited clear discriminative validity. Ultimately, an assessment system comprising 2 first-level indicators, 5 second-level indicators, and 14 third-level indicators was established. The index system developed in this study demonstrates high scientific rigor and practical applicability. It provides a systematic evaluation tool for the hierarchical management and targeted prevention of occupational disease hazards in the automotive repair industry, offering both theoretical support and practical guidance for occupational hazard risk control in this field.
