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。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 482.9 mg·m^-3,significantly higher than the national occupational exposure limit(50 mg·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.
