目的对上海两家车用动力锂离子电池制造企业职业病危害特征和卫生防护效果进行调查与评价,为控制职业病危害提供依据。方法通过卫生学调查、职业病危害因素监测和职业健康检查等方法确定其危害特点和危害性,并评价其防护效果。结果两家企业业存在磷酸铁锂粉尘、活性炭粉尘、石墨粉尘、氧化铝烟(粉)尘、氧化铁粉尘、镍及其无机化合物、锰及其无机化合物、聚偏氟乙烯树脂、N-甲基吡咯烷酮、乙醇、铜烟、六氟磷酸锂、碳酸乙烯酯、碳酸丙烯酯、噪声、工频电场等职业病危害因素,所测定的主要职业病危害因素的浓(强)度均符合相关职业卫生标准的要求。作业人员职业健康体检未发现职业病或疑似职业病病人。结论根据《建设项目职业病危害风险分类管理目录(2012年版)》的规定,该行业属于职业病危害较重的行业,本次调查的两家企业各项防护措施基本达到防护效果,但需定期进行危险性评价,实行危险度管理。
Objective To investigate and evaluate the occupational hazards and health protection effects of two automotive lithium-ion battery manufacturing enterprises in Shanghai and provide the basis for controlling occupational hazards. Methods Through the methods of hygiene investigation, monitoring of occupational hazards and occupational health examination, the characteristics and harmfulness of the damage were determined and the protective effect was evaluated. Results There were lithium iron phosphate dust, activated carbon dust, graphite dust, alumina fume dust, iron oxide dust, nickel and its inorganic compounds, manganese and its inorganic compounds, polyvinylidene fluoride resin, N- Occupational hazards such as pyrithione, ethanol, copper smoke, lithium hexafluorophosphate, ethylene carbonate, propylene carbonate, noise and power frequency electric fields were determined. The determined concentrations of major occupational hazards were all in line with the requirements of relevant occupational hygiene standards. Operators occupational health examination found no occupational disease or suspected occupational disease patients. Conclusion According to the provisions of “2012 Catalog of Occupational Hazards Risk Classification Management of Construction Projects”, the industry belongs to the industries with heavy occupational hazards. The protective measures of the two enterprises in this survey have basically achieved the protective effect, but the risks Evaluation, the implementation of risk management.
