某高原化工企业天然气制乙炔装置职业病危害因素调查

Survey on occupational hazards of acetylene unit with nature gas in a high altitude petrochemical enterprise

目的识别、分析某高原化工企业天然气制乙炔装置工作场所产生的职业病危害因素,确定职业病危害的关键控制点,提出关键控制措施。方法对某高原化工企业天然气制乙炔装置工作场所现场进行职业卫生学调查,并依据GBZ 159-2004《工作场所空气中有害物质监测的采样规范》进行现场职业病危害因素检测。结果该装置存在的主要职业病危害因素为非甲烷总烃、硫酸、氨、一氧化碳、其他粉尘、噪声。检测结果表明,一氧化碳的浓度超标岗位1个,噪声8 h等效声级超过80 d B(A)岗位3个。结论该企业应重点加强设备、应急救援设施的日常维护和保养,注意人员的职业健康监护,确保工人的身体健康。

Objective To identify and analyze the occupational hazard factor of acetylene unit with nature gas,and determine key control points of occupational hazard and suggest some preventive measures. Methods According to GBZ 159-2004 Specifications of Air Sampling for Hazardous Substances Monitoring in the Workplace,occupational hazard factors were detected in a high altitude petrochemical enterprise through occupational hygiene investigation.Results The main occupational hazards in the operation process of unit were total non methane hydrocarbon,sulphuric acid,ammonia,carbon monoxide,other dust,noise. The detection results showed that one carbon monoxide concentration post exceeded the standard and three noises intensities( Lex,8h) were over 80 decibels.Conclusion It is suggested to enhance occupational health surveillance and protective facilities management to assure the worker’s health.
