目的调查引起一起疑似职业性急性1,2-二氯乙烷中毒事故的原因。方法调查1名疑似职业性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、生产作业场所中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;鞋操作位空气中1,2-二氯乙烷浓度CTMA为32.9mg/m3、CSTEL为36.3mg/m3,分别超限3.7和1.6倍;被检的29名底部车间工人中,有19名工人尿中β2-微球蛋白≥1.2μg/ml,异常率为65.5%;自诉症状头晕、头痛、烦燥、恶心、呕吐等15人,异常率为51.7%。结论该次事件中鞋岗位使用的散装港宝水、309黄胶中含高浓度1,2-二氯乙烷,鞋岗位空气中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疑似职业性急性1,2-二氯乙烷中毒事件。
Objective To investigate the causes of a suspected acute occupational acute 1,2-dichloroethane poisoning. Methods To investigate the occupational health management system of a company suspected of occupational 1,2-dichloroethane poisoning, the concentration of harmful substances in the workplace and the occupational health examination of the workers in the workshop. Results The employer did not establish occupational health management rules and regulations; shoes operating position in the air 1,2-dichloroethane concentration CTMA 32.9mg / m3, CSTEL 36.3mg / m3, respectively, 3.7 and 1.6 times the oversight; was seized Among the 29 bottom shop workers, 19 workers had urinary β2-microglobulin ≥1.2 μg / ml with an abnormal rate of 65.5%; 15 cases of dizziness, headache, irritability, nausea, and vomiting were found in private prosecutions. The abnormal rate was 51.7 %. Conclusions In this incident, the bulk port water used in shoe positions and 309 yellow gum contained 1,2-dichloroethane in high concentrations. The 1,2-dichloroethane concentration in the air of shoe positions exceeded the national hygiene limit, Combined with clinical manifestations, we can confirm the incident is suspected of occupational acute 1,2-dichloroethane poisoning.
