天津市某电子元件制造企业职业病危害因素现状调查

Investigation on current situation of occupational hazard factors in an electronic component manufacturing enterprise in Tianjin

目的掌握天津市某电子元件制造企业生产环节存在的主要职业病危害因素种类及暴露程度,评价该企业作业环境职业病危害暴露现状是否符合职业病防治要求,根据存在问题提出针对性改进措施。方法于2021年8—9月对该企业进行职业卫生调查、职业病危害因素检测,并结合职业健康检查结果等资料对劳动者的接触水平及所采取的职业健康措施进行综合分析与评价。结果该企业现有项目主要职业病危害因素有噪声、二甲苯、异丙醇、丙酮、丁酮、二氧化锡、环己酮、石墨粉尘及树脂粉尘等,物理和化学有害因素的检测结果均符合要求,其中噪声8 h等效声级为68.1~84.0 dB(A),存在噪声作业岗位。2019—2021年职业健康监护资料显示,双耳高频听力损失人数呈上升趋势。结论噪声为天津市某电子元件制造企业职业病危害防控的重点,该企业现有防噪声、防粉尘等防护措施能显著降低作业环境职业病危害因素浓度。职业卫生管理较为完善,现状评价结果基本符合国家标准,但噪声防护需进一步加强,应定期开展职业健康检查。

Objective To master the types and exposure degree of the leading occupational hazards existing in the production process of an electronic component manufacturing enterprise in Tianjin,evaluate whether the current situation of occupational hazard exposure in the working environment of the enterprise meets the requirements for the prevention and control of occupational diseases,and propose targeted improvement measures according to the existing problems.Methods The occupational health survey and occupational hazard factor detection in the enterprise were conducted from August to September 2021,and the comprehensive analysis and evaluation were performed on the exposure level of workers and the occupational health measures taken in combination with the occupational health examination results and other data.Results The main occupational hazard factors of the current project in the enterprise included noise,xylene,isopropanol,acetone,butanone,tin dioxide,cyclohexanone,graphite dust,and resin dust.The detection results of the physical and chemical hazardous factors of the enterprise met the requirements,of which the equivalent sound level of noise for 8 hours was 68.1-84.0 dB(A),and there were noise jobs.The occupational health monitoring data from 2019 to 2021 showed that the number of people with high frequency hearing loss in both ears showed an upward trend.Conclusions The noise is the key point of prevention and control of occupational hazards in an electronic component manufacturing enterprise in Tianjin,and the existing protective measures against noise and dust can significantly reduce the concentration of occupational hazards in the working environment.The occupational health management is relatively complete,and the current evaluation results basically meet the national standards,but the noise protection needs to be further strengthened,and the occupational health inspection should be carried out regularly.
