造纸行业职业病危害识别与关键控制点分析

Identification on Occupational Hazards and Analysis of Key Control Points in Paper-Making Process

目的分析某造纸厂生产过程中存在的职业病危害因素及其危害程度,确定职业病危害的关键控制点。方法采用职业卫生调查、职业卫生检测、职业健康检查等对生产过程中存在的职业病危害因素进行识别和分析。结果该厂存在化学毒物、粉尘、噪声、高温、生物致病菌、电离辐射和工频电场等职业病危害因素。现场检测各岗位噪声强度59.1～96.3 dB(A),超标率为35.3%;高温WBGT为29.8～34.3℃,超标率为44.4%;其他职业病危害因素的浓度或强度均符合国家规定的职业接触限值。结论该厂职业病危害因素较多,应对关键控制点加强职业病防治工作。

Objective To analyze the occupational hazards and key control points in the paper mill.Methods The methods of occupational hygiene investigation,detection and medical examination were applied.Results The occupational hazard factors that existed in the paper mill were chemical poisons,dust,noise,high temperature,pathogenic bacteria and radiation.Field monitoring showed that noise intensities ranged from 59.1 dB（A） to 96.3 dB（A） with exceeding rate of 35.3 %,WBGT of high temperature was from 29.8℃ to 34.3℃ with exceeding rate of 44.4%.The other occupational hazard factors met occupational exposure limits.Conclusion The occupational hazard factors are complex and the protection measures should be strengthened to control them.
