某水处理设备生产企业职业病危害调查与分析

Investigation and analysis on occupational hazard factors in a water treatment equipment manufacturing enterprise

目的为了贯彻《中华人民共和国职业病防治法》及其他相关法律法规的要求,识别济南市某水处理设备生产企业可能产生或存在的职业病危害因素,明确企业职业病危害关键控制点,针对职业病危害防护措施及其效果提出相应的整改措施,为监管部门提供管理依据。方法采取工程分析、职业卫生现场调查和现场检测的方法进行分析。结果该企业生产过程中主要职业病危害因素是臭氧、二氧化氮、一氧化碳、电焊烟尘、砂轮磨尘、高频电磁场、紫外线、噪声和高温等。现场检测结果显示仅噪声超标(合格率为75.0%),其他有害因素均符合职业接触限值的要求。近3年在岗期间职业健康检查未发现职业病患者和职业禁忌证。结论该企业属于"职业病危害较重"的建设项目。噪声岗位为该企业职业病危害关键控制点,企业设置了相应的职业病危害防护措施,并在一定程度上降低了职业病危害因素的浓度或强度,该企业职业卫生防护措施和职业卫生管理基本符合国家法律法规的要求。

[Objective]To implement the requirements of the Code of Occupational Disease Prevention of PRC and other relevant laws and regulations,identify the possible occupational hazard factors in a water treatment equipment manufacturing enterprise of Jinan City,analyze the critical control points of occupational hazards in the enterprise,put forward the corresponding improvement measures according to protective measures against occupational hazards and their effects,and provide management basis for regulatory authorities.[Methods]The methods of engineering analysis,field occupational hygienic investigation and field detection were adopted.[Results]The main occupational hazard factors in the production process of the enterprise were ozone,nitrogen dioxide,carbon monoxide,welding fumes,grinding wheel dust,high frequency electromagnetic field,ultraviolet rays,noise,and high temperature.The results of the field detection showed that only the noise intensity exceeded the standard（the qualified rate was 75.0%）,while the concentrations/intensities of other hazard factors met the requirements of occupational exposure limits.In the recent 3 years,no occupational disease patient and occupation contraindication patient was found in the in-service occupational health examination.[Conclusion]The enterprise is classified as a construction project with severe occupational hazards.Noise post is the critical control point of occupational hazard in this enterprise.The enterprise has carried out the corresponding prevention measures against occupational hazards,which reduced the concentrations or intensities of occupational hazards.The occupational protective measures and occupational health management in this enterprise have basically met the requirements of national laws and regulations.
