南方某离子型稀土冶炼分离企业职业卫生分析评价

Analysis and assessment of occupational health in an ion-adsorption rare earth's smelting and separation enterprise in southern China

简述了离子型稀土分离生产工艺流程、物料及产品,分析该项目的生产过程可能存在的职业病危害因素及分布、职业病危害防护设施、个人防护用品、卫生辅助用室、职业卫生管理等情况,并进行工作场所职业病危害因素评价,确定了酸溶、萃取、沉淀、灼烧等车间的危害因素关键控制点.在正常生产情况下,该项目工作场所中的职业病危害因素的浓度和强度可以控制,对劳动者健康不会产生明显影响.

This paper briefly describes the production and separation technology of ion-adsorption rare earth, materials and products, the possibility and distribution of occupational hazard factors exist during the production processes, occupational disease prevention facilities, prevention articles, health auxiliary clinics and occupational health management. Occupational hazards in the workplace were evaluated by determining the critical control points, including soluble material, extraction, precipitation and firing. The concentration and intensity of occupational hazards in the workplace can be controlled during the normal operation without obvious negative effects on workers.
