我们于1982年对省冷湖石油局219名手工电弧焊作业人员进行了劳动卫生与职业病学调查。该局电焊作业均为手工电弧焊,劳动强度大,作业环境普遍较差.除大修厂电焊工房,机厂铆焊车间、钻井管子站工具房、管子站对焊组等较为集中在室内作业外,其它比较分散流动作业.常用焊条为结422、结507、铸造碳化钨焊条等. 车间空气中毒物浓度的测定:使用Fc—1型粉尘采样器,分析方法为磷酸—高碘酸钾法。共测定4个车间,11个点,最低(氧化锰1.4mg/m~3)超过6倍,最廮(氧化锰6.5mg/m~3)超过31倍. 对219名电焊作业工人按照“1971年锰中毒诊断标
In 1982, we conducted a survey on labor hygiene and occupational diseases of 219 hand arc welding workers at the Provincial Lenghu Petroleum Bureau. The Bureau of welding operations are manual arc welding, labor-intensive, generally poor operating environment.In addition to the repair shop welding workshop, machine shop riveting workshop, drilling pipe station tool room, tube station welding group, etc. are more concentrated in the indoor work , The other relatively scattered flow operations commonly used electrodes for knot 422, knot 507, cast tungsten carbide electrode, etc. Workshop air poisoning concentration determination: the use of Fc-1-type dust sampler, the analysis method for the phosphoric acid - potassium periodate method. A total of 4 workshops, 11 points, the lowest (manganese oxide 1.4mg / m ~ 3) more than 6 times, the most (Manganese oxide 6.5mg / m ~ 3) more than 31 times on 219 welding workers in accordance with the "1971 Year of manganese poisoning diagnostic standard
