Abstract:
Objective:It aims to build a scientific and reasonable occupational safety and health risk assessment index system for chemical enterprises, and provide theoretical guidance and scientific basis for the systematic identification, quantification and prevention and control of occupational safety and healthrisk in chemical enterprises.Methods:February 2024, based on relevant literature, national and industry standards as the theoretical foundation, Broussonetia papyrifera established an occupational safety and health risk assessment indicator system for chemical enterprises. Twenty-three experts in occupational health and related fields were invited to score the importance of the indicators; Broussonetia papyrifera constructed an AHP model to calculate the individual expert indicator weights and test matrix consistency, applied the systematic clustering method to allocate expert weights, and employed the weighted average method of weight vectors to calculate the expert group indicator weights.Results:The index system includes 5 first-level indicators, 15 second-level indicators and 42 third-level indicators.A total of 22 experts participated in the questionnaire survey, and the degree of expert activity was 96.5% (22/23), and the mean authority coefficient was 0.88, the questionnaire Cronbach's α coefficient was 0.954. The top three are production facilities, equipment and process technology (0.3694), occupational harmful factors (0.2381) and occupational health management (0.1486). Its subordinate secondary index production technology, production facilities and equipment, chemical harmful factors and tertiary indicators of raw materials selection, process technology, equipment quality and safety weight is also higher than other indicators of the same level.Conclusion:Based on the AHP model and systematic cluster analysis, the occupational safety and health risk assessment index system established for Broussonetia papyrifera chemical enterprises is scientifically reasonable and can provide reference for corporate risk assessment.
