摘　　要：2022年6月广州某键合金丝、键合银丝生产制造企业发生一起源头隐匿的一氧化碳中毒事故,造成10人中毒,其中,1人为一氧化碳中毒,9人为一氧化碳接触反应;症状为头晕、乏力、呕吐,5~7 h后指脉碳氧血红蛋白饱和度为4%~10%,血气生化分析碳氧血红蛋白饱和度为1.9%~5.8%。在企业碳载纯化装置中的气体检测一氧化碳浓度为34.46~37.26 mg/m^(3)。判断事故为碳载纯化装置运行异常产生一氧化碳气体随输气管道输送至作业岗位导致的一氧化碳中毒。本文通过排查毒物来源和中毒原因,为同类工艺预防类似事件提供警示,为化学中毒风险识别提供新的思路。同时,警示同类企业应充分考虑特定情况下的中毒风险,加强设备维护检修,防止类似事件的发生。In June 2022,a carbon monoxide poisoning accident with hidden source occurred in a bonded gold/silver wire manufacturing enterprise in Guangzhou,causing 10 people to be poisoned,of which 1 was caused by carbon monoxide poisoning and 9 by carbon monoxide contact reaction.The symptoms were dizziness,fatigue and vomiting.After 5 to 7 h,the saturation of carboxyhemoglobin in finger pulse was 4%to 10%,and the saturation of carboxyhemoglobin in blood gas biochemical analysis was 1.9%to 5.8%.The concentration of carbon monoxide detected in the carbon borne purification plant of the enterprise was 34.46-37.26 mg/m^(3).It was judged that the accident was carbon monoxide poisoning caused by carbon monoxide gas being transported to the work post along the gas transmission pipeline due to abnormal operation of the carbon borne purification plant.By investigating the source and cause of poison,this paper provides a warning for the similar process to prevent similar events,and provides a new idea for the identification of chemical poisoning risk.At the same time,it is warned that similar enterprises should fully consider the risk of poisoning under specific circumstances,strengthen equipment maintenance and repair,and prevent the occurrence of similar incidents.
