摘　　要：目的从源头控制或消除职业病危害,保护劳动者健康。方法根据职业卫生学调查和现场检测结果,对某新建不锈钢生产项目的职业病危害控制效果,按规范进行综合评价。结果在总体布局、生产工艺与设备布局、建筑卫生学、职业病危害防护设施、应急救援、辅助用室等方面基本符合相关要求,但炉前、上料、出渣、浇铸机和煤气发生炉岗位劳动者接触粉尘的时间加权平均浓度超过国家规定的相应职业接触限值要求,分别为8.2、8.5、1.3(矽尘)、8.7、4.9 mg/m3(煤尘);混料、机烧、炉前、出渣、浇铸机岗位噪声8 h等效连续A声级分别为88.9、88.5、92.5、94.2、89.0 d B(A),超过职业接触限值85 d B(A)的规定。结论该项目在确保职业病危害防护设施运行正常、个体防护措施到位,各项职业卫生管理制度落实,采纳职业病危害控制效果评价报告书提出的建议的情况下,职业病危害控制效果基本合格,可以进行职业病危害防护设施的现场验收。Objective To evaluate the control effect of occupational hazards on a new project of stainless steel production.Methods The comprehensive evaluation was based on occupational health investigation and field test results.Results All of the overall layout,production process and equipment layout,building hygiene,protective facilities for occupational diseases,emergency rescue,auxiliary rooms basically met the relevant national standards. But in the furnace,feeding,slag,casting machine,and gas generator,the time-weighted average concentration of workers exposed to dust exceeded the corresponding occupational exposure limits,were 8.2,8.5,1.3（ silicon dust）,8.7 and 4.9 mg/m3（ dust）; In the mixing,burning machine,furnace,slag,8 h equivalent continuous A noise level were 88.9,88.5,92.5,94.2,89.0 d B（ A）,exceeding the occupational exposure limit of 85 d B（ A）.Conclusion With normal operation of protective facilities of occupational hazards,good personal protection measures,complete implementation of management systems of occupational health and the recommendations from the report of control effect on occupational hazards,the control effect of occupational hazards is basically qualified,and the field acceptance of protective facilities of occupational hazards can be performed.
