一起废旧化工塑料桶处置过程中急性硫酸二甲酯中毒事故的报告

Investigation on an acute dimethyl sulfate poisoning accident caused by improper disposal of discarded chemical plastic barrels

  • 摘要: 通过对某个体废品收购点处置废旧化工塑料桶过程中发生的一起急性中毒事故进行调查,详细询问中毒病人的职业史、病史及就诊经过,查阅病人住院病历记录;对中毒事故现场进行职业卫生学调查和职业卫生检测。分析事故发生原因,以避免类似中毒事件再次发生。经检测:作业场所硫酸二甲酯质量浓度为11.1 mg/m3。4名患者分别被诊断为急性硫酸二甲酯中毒(中度)2例,急性硫酸二酯中毒(轻度)1例,职业性硫酸二甲酯刺激反应1例。3名中毒患者经抗炎及对症治疗2周后痊愈出院;1名硫酸二甲酯接触刺激反应者经对症处理并门诊观察48 h无变化后出院。该中毒事故的主要原因为废旧化工塑料桶处置过程中未采取有效防护措施。

     

    Abstract: We invesitgated an acute poisoning accident caused by improper disposal of discarded chemical plastic barrels in a private junk yard through asking about patients' occupational history, medical history, and medical treatment process, reviewing medical records, and conducting a field investigation on occupational hazards at the reported scene. We analyzed the potential causes of the accident, aiming to avoid similar poisoning accidents in the future. The concentration of dimethyl sulfate (DMS) in the junk yard was 11.1 mg/m3. Four patients were diagnosed as moderate acute DMS poisoning (n=2), mild acute DMS poisoning (n=1), and occupational dimethyl sulfate irratative reaction (n=1), respectively. The three poisoning patients were discharged from hospital after two weeks of anti-inflammatory and symptomatic treatment, and the other one was discharged after symptomatic treatment and 48 h of clinic observation. The main cause of the poisoning accident is the lack of effective protective measures during the disposal of discarded chemical plastic barrels.
