This study aimed to analyze the relationship between clinical status and work characteristics of firefighters and other public officers who engaged on collection duties in the site of the hydrogen fluoride spill that occurred on September 27, 2012, in Gumi City, South Korea.
We investigated the clinical status, personal history, and work characteristics of the study subjects and performed physical examination and several clinical examinations, including chest radiography, echocardiography, pulmonary function test, and blood testing in 348 firefighters, police officers, volunteer firefighters, and special warfare reserved force who worked at the hydrogen fluoride spill area.
The subjects who worked near the accident site more frequently experienced eye symptoms (p = 0.026), cough (p = 0.017), and headache (p = 0.003) than the subjects who worked farther from the accident site. The longer the working hours at the accident area, the more frequently the subjects experienced pulmonary (p = 0.027), sputum (p = 0.043), and vomiting symptoms (p = 0.003). The subjects who did not wear respiratory protective devices more frequently experienced dyspnea than those who wore respiratory protective devices (p = 0.013). In the pulmonary function test, the subjects who worked near the accident site had a higher decease in forced vital capacity than the subjects who worked farther from the site (p = 0.019); however, no statistical association was found between serum calcium/phosphate level, echocardiography result, chest radiographic result, and probation work characteristics.
The subjects who worked near the site of the hydrogen fluoride spill, worked for an extended period, or worked without wearing respiratory protective devices more frequently experienced upper/lower respiratory, gastrointestinal, and neurological symptoms. Further follow-up examination is needed for the workers who were exposed to hydrogen fluoride during their collection duties in the chemical plant in Gumi City.
本研究旨在分析2012年9月27日韩国龟尾市发生的氟化氢泄漏事故现场从事收集任务的消防员及其他公职人员的临床状况与工作特征之间的关系。
我们调查了348名在氟化氢泄漏区域工作的消防员、警察、志愿消防员和特种作战预备役人员的临床状况、个人病史及工作特征，并进行了体格检查和多项临床检查，包括胸部X线摄影、超声心动图、肺功能测试及血液检测。
与在距事故现场较远区域工作的人员相比，在事故现场附近工作的人员更频繁地出现眼部症状（p = 0.026）、咳嗽（p = 0.017）和头痛（p = 0.003）。在事故区域工作的时间越长，人员出现肺部症状（p = 0.027）、咳痰（p = 0.043）和呕吐症状（p = 0.003）的频率越高。未佩戴呼吸防护装置的人员比佩戴呼吸防护装置的人员更频繁地出现呼吸困难（p = 0.013）。在肺功能测试中，在事故现场附近工作的人员的用力肺活量下降幅度高于在距现场较远区域工作的人员（p = 0.019）；然而，血清钙/磷水平、超声心动图结果、胸部X线摄影结果与工作特征之间未发现统计学关联。
在氟化氢泄漏事故现场附近工作、工作时间较长或未佩戴呼吸防护装置工作的人员更频繁地出现上/下呼吸道、胃肠道和神经系统症状。对于在龟尾市化工厂收集任务期间接触过氟化氢的工人，需要进一步进行随访检查。
