摘　　要：目的了解某电子企业喷码机保养岗位丁酮超标情况,及整改的措施和过程,为同类型企业超标岗位的治理提供参考。方法通过现场职业卫生调查、工艺改进和现场检测等收集相关数据,分析超标岗位整改的合理性和可行性。结果通过现场多次工艺改进,将岗位单独设置,增设有效的防护设施后,超标岗位的丁酮浓度从894.2 mg/m^(3)(>5 OELs)下降至4.4mg/m^(3)(≤10%occupational exposure limits,OELs),符合国家标准规定的职业接触限值。结论企业成功地完成了岗位丁酮浓度超标的整改。将岗位独立设置,采用密闭抽风防护措施是降低岗位职业病危害因素浓度的有效方法。Objective To understand the situation of butanone exceeding the standard in the maintenance post of inkjet printer,and the measures and process of rectification in an electronic enterprise,and to provide reference for the management of over-standard posts in the same type of enterprises.Methods The relevant data were collected through on-site occupational health survey,process improvement and on-site detection.The rationality and feasibility of rectification of posts exceeding the standard were analyzed.Results Through many on-site process improvements,the posts were set up separately and effective protective facilities were added,and the concentration of butanone in the posts exceeding the standard was reduced from 894.2 mg/m^(3)(>5 OELs)to 4.4 mg/m^(3)(≤10%OELs),which was in line with the occupational exposure limit specified in the national standard.Conclusion The enterprise has successfully completed the rectification of the excessive concentration of butanone in the inkjet printer maintenance posts.It is an effective way to reduce the concentration of occupational hazards by setting up posts independently and adopting closed ventilation protection measures.
