目的了解工作场所职业病危害因素整改后的效果,为防治职业病提供科学依据。方法按(GBZ159-2004)《工作场所空气中有害物质监测的采样规范》和(卫法监发[2002]63号)《建设项目职业病危害评价规范》进行职业卫生调查、检测,并对结果进行比较分析。结果工作场所空气中粉尘测定点合格率提高了40.0%,CO、NH3测定点合格率分别提高了29.1%和50.0%,噪声测定点合格率提高了22.2%。结论工作场所职业病危害因素整改后得到较明显改善。
Objective To understand the effect of rectification of occupational hazards in the workplace and provide a scientific basis for the prevention and treatment of occupational diseases. Methods According to GBZ159-2004 Sampling Specification for Monitoring of Airborne Hazardous Materials in Workplace and Wei-Wei-Jian-Fa [2002] No. 63 Occupational Disease Hazard Evaluation Code for Construction Project, occupational health investigation and testing were conducted and the results were carried out comparative analysis. Results The passing rate of dust in the air of the workplace was increased by 40.0%, the passing rates of CO and NH3 were increased by 29.1% and 50.0% respectively, and the passing rate of noise measurement points increased by 22.2%. Conclusion The workplace occupational hazards have been significantly improved after rectification.
