目的了解、掌握某冶炼厂生产工艺中职业危害状况,为搞好防治提供依据。方法对冶炼厂进行职业病危害因素调查与检测。结果一氧化碳、二氧化碳、铜烟、二氧化氮检测结果符合国家职业卫生标准,铅尘、铅烟、二氧化硫、砷化氢、砷化物、镉、氧化锌、粉尘、噪声岗位接触浓度或强度均有不同程度超标(超标率为5.9%～62.5%),其中以铅烟、砷化氢、镉超标明显,其岗位时间加权平均浓度(TWA)最高超过国家卫生标准分别为58.6倍、32.7倍、123倍。对该厂384名冶炼工人进行职业性体检,诊断为轻度铅中毒的146人(38.0%)。结论该冶炼厂职业病危害较严重,应加强综合治理与健康监护。
Objective To understand and master the occupational hazards in a smelter’s production process and provide the basis for prevention and treatment. Methods Investigation and detection of occupational hazards in smelters. Results The test results of carbon monoxide, carbon dioxide, copper smoke and nitrogen dioxide met the national occupational health standards. Lead dust, lead smoke, sulfur dioxide, arsine, arsenide, cadmium, zinc oxide, dust and noise were all different in the exposure concentration or intensity (Exceeding the standard rate of 5.9% ~ 62.5%), of which lead smoke, arsine, cadmium exceeded the standard, the post time weighted average concentration (TWA) highest than the national health standards were 58.6 times, 32.7 times, 123 times . Occupational physical examinations of 384 smelters at the plant were diagnosed as 146 (38.0%) with mild lead poisoning. Conclusion The smelter occupational hazards more serious, should strengthen the comprehensive management and health monitoring.
