ObjectiveTo explore the applicability of semi-quantitative comprehensive index method in occupational health risk assessment in domestic waste incineration industry.
MethodsThe flue gas purification system in a domestic waste incineration plant was selected as the study subject. The risk assessment of chemical hazards were conducted using semi-quantitative comprehensive index method in the “Guidelines for occupational health risk assessment of chemicals in the workplace” （GBZ/T 298—2017）.
ResultsThe occupational health risk levels of hydrogen chloride， sulfur dioxide and activated carbon were low while using flue gas purification system， while the risk levels of lead and lead compounds， cadmium and cadmium compounds， ammonia and sodium hydroxide were medium.
ConclusionThe assessment results of semi-quantitative comprehensive index method are basically consistent with the current situation of occupational health risk of flue gas purification system in a domestic waste incineration plant， which can provide the basis for enterprises to take occupational health risk control measures.
