Abstract:
OBJECTIVE: To establish an indicator system for risk assessment on occupational dust hazards and verify its application. METHODS: Using Delphi method,two rounds of investigation were made from 30 experts who work on frontline occupational health. The indicator system for risk assessment was established based on the investigation,statistics and boundary value,in fully consideration with the interaction of three basic elements of“dust inherent characteristics-laborers factors-influencing factors”. The indicator system was applied to evaluate the risk of 90 workplaces in the presence of dust occupational risk factors. RESULTS: The positive coefficient of experts' opinion was 90%,and the coefficient of experts' authority was 0. 808. The coefficient of experts' consensus was 0. 50( χ~2= 120. 56,P < 0. 01). The indicator system for risk assessment on occupational hazards of dust factors has been successfully established. This system included three class A indicators,nine class B indicators and twenty-eight class C indicators. The total coincidence rate of assessments on the risk level of occupational dust hazards of workplaces was 60%( Kappa = 0. 452,P < 0. 01). CONCLUSION: This indicator system was objective,scientific and feasible,and could reflect the actual levels of occupational dust hazards.
