粉尘作业场所职业健康风险评估及分级管控策略

Dust-exposure workplace is widespread in industrial production sites. Dust can cause occupational diseases such as pneumoconiosis, posing a serious threat to the health of workers. It is crucial to scientifically assess risks and implement graded control measures. Based on the dust detection data from 21 enterprises in different industries, four core indicators including dust concentration and free silica content were selected. The risk levels were classified using the comprehensive index method, and the differences in risks between industries and positions were analyzed. For high, medium and low-risk positions, targeted control strategies were formulated from the aspects of engineering technology, individual protection, and management measures, and four guarantee measures of organization, system, technology and funds were proposed. Different risk levels of high, medium, and low positions were clearly defined for graded control. Graded control can effectively reduce risks. In the future, intelligent technology should be utilized to achieve precise control, while strengthening government supervision and social publicity to promote enterprises to fulfill their main responsibilities.
