[目的]调查引起一起急性1,2-二氯乙烷中毒事故的原因。[方法]调查1名急性职业性1,2-二氯乙烷中毒病人所在公司的各项职业卫生管理体制、生产作业场所有害物质浓度和同车间接触人员的职业健康检查情况。[结果]用人单位未建立职业卫生管理规章制度;上糊生产线岗位1,2-二氯乙烷浓度CTWA为23.6mg/m3、CSTEL为261.1mg/m3,分别超限2.4倍和16.4倍;应急医学健康检查人数为125人,其中有101名工人需进行职业性复查,其中有26名工人尿β2-微球蛋白≥1.8μg/ml,属重点复查人员,其他各种职业性异常(如尿β2-微球蛋白偏高、血白细胞偏低、主诉体征症状及神经系统检查异常者)共有75人。[结论]本次事件中上糊生产线岗位使用的5种胶粘剂中含高浓度1,2-二氯乙烷,上糊生产线岗位空气中1,2-二氯乙烷浓度超过国家卫生限值规定,结合临床表现,可以确认该起事件为急性职业性1,2-二氯乙烷中毒事件。
[Purpose] To investigate the causes of an acute 1,2-dichloroethane poisoning accident. [Methods] To investigate the occupational health management system, the concentration of harmful substances in the workplace and the occupational health examination of the workers in the workshop with 1 acute 1,2-dichloroethane poisoning patient. [Results] The occupational health management rules and regulations were not established by the employer. The CTWA of post-paste production line was 23.6mg / m3 and the CSTEL was 261.1mg / m3, which exceeded the limits by 2.4 times and 16.4 times respectively. The emergency The number of medical examination is 125, of which 101 workers need professional review. Among them, 26 workers have urinary β2-microglobulin≥1.8μg / ml, which belongs to the key review personnel. Other occupational abnormalities such as urine β2-microglobulin is high, low white blood cells, signs of symptoms and neurological abnormalities were reported) a total of 75 people. [Conclusion] The five kinds of adhesives used in the layup production line contained 1,2-dichloroethane in high concentrations and the concentration of 1,2-dichloroethane in the air of the paste production line exceeded the national health limit , Combined with clinical manifestations, can confirm the incident as acute occupational 1,2-dichloroethane poisoning.
