【摘要】：目的了解惠州市水泥粉磨站职业病危害现状,探讨防治对策。方法采用方便抽样的方法,以惠州市2014—2015年9家水泥粉磨站为研究对象,进行职业卫生现场调查、作业工人职业健康检查,对其粉尘和噪声接触水平进行检测和评价。结果该9家水泥粉磨站粉尘中游离二氧化硅水平均大于10.0%。球磨、包装、装车和散装岗位工人个体总粉尘时间加权平均浓度(CTWA)超标率达到100.0%,装车岗位工人个体呼吸性粉尘CTWA超标率最高(33.3%),包装岗位工作场所总粉尘CTWA超标率最高(85.7%),包装岗位工作场所呼吸性粉尘CTWA超标率最高(33.3%)。球磨岗位8 h等效声级超标率最高(为88.5%)。部分水泥粉磨站未按规范为工人配备防尘口罩和防护耳塞,职业卫生管理不规范;粉尘项目的职业健康检查发现职业禁忌证3人、疑似职业病2人。结论应加强惠州市水泥粉磨企业的职业病监督管理工作,切实保障粉尘作业工人身体健康。
[Abstract]:Objective to understand the present situation of occupational hazards in cement grinding stations in Huizhou City, and to explore the prevention and treatment measures. Methods the occupational hygiene field investigation was carried out on 9 cement grinding stations in Huizhou from 2014-2015 to 2014-2015 by using convenient sampling method. The exposure level of dust and noise was measured and evaluated. Results the level of free silica in the dust of the 9 cement grinding stations was higher than 10.0. The average concentration of individual dust in loading and bulk workers was 100.00.The CTWA rate of individual respiratory dust exceeded the standard by 33.3%, and the total dust CTWA exceeded the standard rate of 85.7% and packed post. The CTWA excess rate of respiratory dust in the workplace was the highest (33.3%). The equivalent sound level exceeded the standard rate of 8h in the ball milling station was the highest (88.5%). Some cement grinding stations were not equipped with dustproof masks and earplugs according to the specifications. Occupational health management was not standardized, occupational health examination of dust project found 3 occupational contraindications and 2 suspected occupational diseases. Conclusion the supervision and management of occupational diseases in cement grinding enterprises in Huizhou should be strengthened. Ensure the health of dust workers.
