某轨道车辆制造公司车体表面处理过程中的职业病危害因素
|
摘要
目的明确某轨道车辆制造公司车体表面处理过程中可能产生的职业病危害因素,分析其危害程度及对劳动者健康的影响,提出防护对策,以减少职业病的发生。方法依据国家相关标准,采用检查表法、类比法、工程分析法进行综合分析评价。结果类比检测结果表明,类比企业打磨工作业时接触的其他粉尘、苯乙烯、乙酸乙酯浓度均小于职业接触限值;接触噪声的8 h等效连续A声级结果小于80 dB(A)。腻子间是职业病危害防治的关键控制点。结论正常运行情况下,作业人员接触职业病危害因素强度均符合职业限值要求,但应关注腻子打磨工序的抽风除尘设施维修,确保其正常运行,可有效防止职业危害。
Objective To confirm the possible occupational hazard in process of surface treatment in a railway vehicle manufacturing company, to analyze the harm degree and the influence on the workers' health.Then give related protective to reduce the occurrence of occupational diseases.Methods According to the relevant national standard, using analogy method,checklist method,engineering analysis method for comprehensive analysis and evaluation.Results The results of analogy detecting showed that the concentration of other dust, styrene and ethyl acetate which worker exposed to were blow the occupational exposure limit.L_(EX,8 h) of workers exposed to painting is below 80 dB(A).The putty mill is critical control point of occupational hazard.Conclusion In normal operation conditions, the strength of occupational disease hazards encountered by the workers meets the requirements of the occupational limit, but it is necessary to pay attention to the maintenance of the pneumatic dust removal facilities of the putty grinding process to ensure its normal operation, which can effectively prevent occupational hazards.
