摘　　要：目的对某稀土合金生产线职业病危害因素进行识别、分析,对职业病危害作业进行分级,为监管部门和企业职业卫生管理提供科学有效的数据。方法采用职业卫生现场调查法、职业病危害因素检测法、职业健康监护等方法并结合国家职业卫生相关标准对职业病危害作业进行分级,并根据企业现有情况,提出针对性整改措施。结果该项目职业病危害因素为稀土粉尘、氟化氢、一氧化碳、二氧化碳、高温和噪声等。粉尘危害集中在电解车间。粉尘岗位8 h时间加权浓度合格率为为其中2#电解车间电解岗位粉尘分级为Ⅱ级,属中度危害作业,其它电解车间电解岗位粉尘分级为Ⅰ级,属轻度危害作业;各岗位噪声检测结果和有毒物质的检测结果均符合国家卫生限值的要求,合格率为100%。结论该项目电解车间稀土粉尘危害较为严重,针对稀土粉尘浓度超标现状,应加强职业病危害防护设施有效运行,完善各项职业病规章制度。Objective To identify and analyze occupational hazards in the productionline of Rare earth alloy ,To Classificate Oc-cupational Hazards At Workplace, and provide scientific and effective datas for regulators and occupational health management . Methods Field investigation and detection of occupational risk factors and occupational health monitoring were applied. Combined with the relerant standard, Occupational Hazards Classification At Workplace were carried out and according to the enterprise ’s conditions,the improving measures were put forward.Results The main occupational hazards were rare-earth dust,chemical toxi-cant（hydrogen fluoride,carbon monoxide,carbon dioxide,etc） ,high temperature and noise.The time weighted average concentra-tions of dust accorded with national standards pass rate was 58.8%. The work classification of rare earthdust bout 2# Electrolytic workshop wasⅡ （morderrate damage work）; The work classification of rare earthdust bout other Electrolytic workshop wasⅠ（mild damage work）; the qualified rate of noise and chemical toxicant in workplaces was100%.Conclusion The rare earth dust hazard is serious at Electrolytic workshop in this enterprise,According to current situation of rare earth dust concentration exceeding the re-quirement of national standards , the effective operation of occupational hazards prevention facilities Should strengthen, Make per-fect the rules and regulations of the occupational disease.
