目的通过事件的调查分析,对工业企业部门的安全生产教育起到警示作用。方法回顾性流行病学调查和现场实验监测调查。结果用红外线分析器进行二氧化碳检测,井周围二氧化碳含量在0.034%～0.045%之间;井口下1m处二氧化碳含量超过分析器的检测上限(5000ppm=0.5%),无法正常读数,超过正常值4倍以上;工厂没有配备相应的防毒面具及其他防护设备。结论经流行病学调查、临床表现分析和实验室检验结果证实,此起中毒事件是由二氧化碳污染水井引起的职业中毒;乡镇企业工人及有关部门安全意识淡薄,对急性二氧化碳气体中毒的危害认识不足,个人防护及其他防护设备缺乏,造成5人中毒其中4人死亡。
Objective Through the investigation and analysis of the incident, it plays a warning role in the safety education in industrial enterprises. Methods Retrospective epidemiological investigation and field experiment monitoring survey. Results Carbon dioxide was detected by an infrared analyzer. The content of carbon dioxide around the well was between 0.034% and 0.045%. The carbon dioxide content at 1m below the wellhead exceeded the upper limit of the analyzer (5000ppm = 0.5%) and could not be read normally, more than 4 times of normal Above; the factory is not equipped with the corresponding gas masks and other protective equipment. Conclusions The results of epidemiological investigation, clinical manifestations and laboratory tests confirm that this poisoning incident is caused by occupational poisoning caused by carbon dioxide-contaminated wells. The awareness of workers and relevant departments of township and village enterprises is weak and their awareness of the dangers of acute carbon dioxide gas poisoning is insufficient , The lack of personal protection and other protective equipment caused 4 deaths of 5 people.
