一起急性职业性甲醇中毒事故的调查分析

Investigation and analysis of an acute occupational methanol poisoning accident

  • 摘要:

    对昆山市某精密五金制品有限公司4名发生疑似甲醇中毒的工人进行现场调查和流行病学调查,发现工人所在高光岗位甲醇的时间加权平均容许浓度达到482.9 mg·m-3,远远高于职业接触限值(50 mg·m-3)。通过现场调查发现该企业在高光岗位无局部通风设施,工人未佩戴有效个人防护用品,工人在入职时未参加岗前职业健康体检,另外,第三方技术服机构在进行现状评价检测时未对甲醇进行识别和检测,导致工人吸入高浓度甲醇出现神经系统及视力模糊等症状。

     

    Abstract:

    A field investigation and an epidemiological investigation were carried out on four workers being suspected methanol poisoning victims in a precision metal products factory in Kunshan City. The time weighted average permissible concentration of methanol in the highlight station reached 482.9mg·m-3, significantly higher than the national occupational exposure limit (50mg·m-3). Without installed local ventilation facility, these victims reported not wearing effective personal protective equipment and not having pre-job occupational health examination. Besides, the third-party technical service suppliers failed to identify and detect methanol. Such factors contributed to the four victims' neurologic signs and blurred vision after inhaling high-concentration methanol.
