目的通过对某新型蒸压粉煤灰砖厂项目产生的职业病危害因素进行检测和对工作场所中职业病危害作业进行分级,了解其用于职业病危害控制效果评价的可行性。方法采用职业卫生现场调查、检测检验法、定量分级法和职业健康检查法相结合的方法进行评价。结果生产过程中工人接触的主要职业病危害因素为粉尘和噪声,搅拌机、轮碾机等工作场所中粉尘作业分级结果为Ⅰ级,制砖机工作场所中粉尘作业分级结果为Ⅱ级,球磨机、轮碾机、制砖机等工作场所中噪声作业分级均为Ⅰ级。结论现场检测法和工作场所职业病危害作业分级相结合,能够更科学地对建设项目的职业病危害控制效果做出综合评价,为企业职业卫生日常管理工作提供依据。
OBJECTIVE To test the feasibility of occupational disease hazard control in occupational diseases by detecting the occupational disease hazards generated by a new type autoclaved fly ash brick factory and grading occupational hazards in the workplace. Methods Occupational health field surveys, test methods, quantitative grading and occupational health examination methods were evaluated. Results The main hazards of occupational hazards exposed by workers in the production process were dust and noise. The grading results of dust in workplaces such as blenders and wheel mills were grade Ⅰ. The grading results of dust in brick workplaces were grade Ⅱ, ball mill and wheel Grinding machine, brick machine and other workplace noise levels are grade Ⅰ. Conclusion The combination of on-site detection method and occupational hazard classification in the workplace can make a comprehensive evaluation of the control effect of occupational hazards in construction projects more scientifically and provide the basis for the daily management of occupational health in enterprises.
