【摘要】：目的分析某水电生产企业运行期间存在的职业病危害因素及其危害程度,确定职业病危害关键控制点。方法采用检查表法、职业卫生调查法、检测检验法、工程分析法相结合的原则,对职业病危害进行识别和评价。结果该企业存在的职业病危害因素主要有噪声、工频电场、振动、夏季高温、苯、甲苯、二甲苯、苯乙烯、一氧化碳、二氧化碳、正己烷、丙酮、电焊烟尘和氡。职业病危害因素监测结果显示,噪声强度检测38个点,其中3个检测点噪声强度超过85 d B(A),其中检修廊道2号机尾水人孔处的噪声强度最大达到93.4 d B(A);个体噪声强度检测5个巡检岗位,其中有2个(占40%)超过职业卫生限值。其余所测职业病危害因素检测结果符合国家卫生标准。结论该企业职业病危害因素较复杂,主要职业病危害因素为噪声和工频电场,应从职业病危害发生的关键控制部位加强防治工作。
[Abstract]:Objective to analyze the factors of occupational disease hazards and the degree of their hazards during the operation of a hydropower production enterprise, and to determine the critical control points of occupational disease hazards. Methods the inspection table method, occupational health survey method and detection test method were used. Results the occupational hazard factors in this enterprise are noise, power frequency electric field, vibration, summer high temperature, benzene, toluene, xylene, styrene, etc. Carbon monoxide, carbon dioxide, n-hexane, acetone, welding smoke and radon. Monitoring results of occupational hazard factors show that noise intensity is detected at 38 points, The noise intensity of three of the detection points exceeded 85 dB / A, of which the maximum noise intensity was 93.4 dB at the manhole in tail water of the repair corridor No. 2, and the individual noise intensity detection was carried out in 5 inspection posts, the maximum noise intensity was 93.4 dB at the manhole in the tail water of the repair corridor No. 2 machine. Among them, 2 (40%) exceeded the occupational health limit. The results of the other occupational disease hazard factors were in line with the national health standard. Conclusion the occupational disease hazard factors in this enterprise are more complicated, the main occupational disease hazards are noise and frequency electric field. The prevention and control work should be strengthened from the key control position of occupational disease hazard.
