某电解铝车间职业病危害因素分析

目的探讨电解铝车间职业病危害因素分布及工人个体接触水平,分析其危害程度对劳动者健康的影响,评价职业病危害防护措施及其效果。方法采用职业卫生现场调查、系统工程分析、现场监测、实验室分析进行分析与评价。结果存在的主要职业病危害因素为氧化铝粉尘、二氧化硫、氟化物、一氧化碳、二氧化碳、高温、电磁辐射和噪声;该车间工人接触氧化铝粉尘、二氧化硫、氟化物、一氧化碳、二氧化碳的时间加权平均浓度合格率均为100%,工人接触噪声8 h等效声级计算结果合格率为100%,工作场所中高温、电磁辐射结果均符合要求。结论通过现场调查和检测结果表明,该电解车间预焙槽自动化程度高,防护设施运行良好,检测结果均符合职业卫生限值要求,用人单位应加强日常管理确保防护设施正常运行,加强职业健康监护防止职业病的产生。

Analysis of occupational risk factors in the electrolytic aluminum workshop

Objective To explore the occupational hazards distribution and workers＇ individual exposure levels, analyze the damage degree of impact on the health of workers and evaluate protective measures. Methods The risk factors were analyzed combining with filed investigation, system engineering analysis, field monitoring and detection. Results The main occupational risk factors were alumina dust, sulfur dioxide, carbon monoxide, carbon dioxide, fluoride, high temperature, electromagnetic radiation and noise. The time weighted average concentrations of sulfur dioxide, alumina dust, carbon mon- oxide and carbon dioxide accorded with national standards, pass rate was 100% ;Qualified rate of noise was 100% ;in the workplace, the electromagnetic radiation and high temperature were in line with the requirements of national stand- ards. Conclusion Test results are in line with the occupational health requirements, the employing units shall strengthen the daily management to ensure the normal operation of protective facilities, strengthen the occupational health care to prevent occupation diseases.
