某电子化学品项目职业病危害因素识别和关键控制点分析

Identification of Occupational Hazards Factors and Analysis of Critical Control Points in an Electronic Chemicals Project

目的通过识别、分析某电子化学品工程可能产生的职业病危害因素及危害程度,找出关键控制点,探讨防护对策和措施,为有关行政部门审批提供技术依据。方法采用类比法和定量分析法进行评价。结果该建设项目存在的职业病危害因素有噪声、高温、化学毒物和工频电磁场等,其中主要职业病危害因素为化学毒物,有氨、氟化氢、盐酸、硫酸、硝酸、冰醋酸、醋酸丁酯、磷酸等。结论该工程存在的职业病危害因素比较复杂,其中主要危害因素为化学毒物,应从职业病危害发生的关键控制部位加强防治。综合评价表明,该工程生产过程中可能产生的职业病危害因素是可以预防和控制的。

[Objective]By identifying and evaluating the possible occupational hazards factors and damage degree in an electronic chemicals project,to find out the critical control points,study the protective measures,and provide the technical basis for approval of administrative department.[Methods]The evaluation was conducted by methods of analogy and quantitative classification.[Results]The occupational hazards factors in this construction project were noise,high temperature,chemical poisons and power frequency electromagnetic field.The chemical poisons were main occupational hazards factor,which included ammonia,hydrogen fluoride,hydrochloric acid,sulfide acid,nitric acid,acetic acid,n-butyl acetate and phosphoric acid.[Conclusion]The occupational hazards factors in this construction project were complicated,chemical poisons were main hazards factor,and the prevention measure should be strengthened in the critical control points.The comprehensive evaluation showed that the occupational hazard factors in the production process of this project can be controlled and prevented.
