现代化水泥生产企业职业危害调查与分析

Nvestigation and Analysis of Occupational Hazards of Modern Cement Productive Companies

目的:了解、掌握现代化水泥生产企业的职业危害防治现状,为同行业职业风险分类管理提供借鉴经验。方法:职业卫生现场调查、工作场所中职业危害因素时空分布检测和查阅安全生产管理及健康档案资料。结果:工作场所空气中矽尘加权平均浓度(1.23±0.52)mg/m3、水泥尘加权平均浓度(4.19±3.48)mg/m3、一氧化碳平均浓度(12.725±0.345)mg/m3、二氧化氮平均浓度(0.085±0.005)mg/m3、二氧化硫平均浓度(0.15±0.04)mg/m3、噪声强度(76.5±15.6)dB(A),职业危害因素暴露水平未超出职业接触限值。结论:采取积极的综合防治措施,同时加强管理,可以使水泥企业工作场所中职业危害因素达到有效控制。

Objective：To understand and master the current situation of occupational hazards of modern cement enterprises,serving as a reference for the professional risk classification management.Methods：Occupational health field in-vestigation,the detection of the time and space distribution of occupational hazard factors in the workplace,as well as the access to safe production management and health records.Results：The average concentration of silica dust in the air of workplace was （1.23±0.52）mg/m3 ,the average concentration of cement dust was（4.1 9±3.48）mg/m3 ,the average con-centration of carbon monoxide was （12.725 ±0.345 ）mg/m3 ,the average concentration of nitrogen dioxide was （0.085 ± 0.005）mg/m3 ,the average concentration of sulfur dioxide was（0.1 5 ±0.04）mg/m3 and the noise intensity was （76.5 ± 1 5.6）dB（A）.Furthermore,the exposure level of occupational hazard factors did not exceed the occupational exposure limit. Conclusion：As long as we take effective prevention and control measures,strengthen management at the same time,the occu-pational hazard factors in the workplace of the cement enterprise can be effectively controlled.
