New labelling processes installed without adequate ventilation control in an electric motor factory exposed production line workers to toxic gases. Symptoms of eye and respiratory tract irritation together with complaints of headache, fever, chills, dizziness, malaise, general weakness, nausea, and vomiting were widespread. Chest signs, radiographic abnormalities, reduction in ventilatory function, and blood gas abnormalities were found in some cases. Epidemiological analysis of the spatial and temporal distribution of cases supported an exposure effect relationship. Investigations suggested ozone and possibly phosgene and associated trichloroacetyl chlorides as the toxic agents that were generated by an ultraviolet print curing arrangement and perchloroethylene used as a cleaning solvent.
一家电机厂安装了新的标签工艺，但没有适当的通风控制，致使生产线工人接触到有毒气体。眼部和呼吸道刺激症状普遍存在，同时还有头痛、发烧、寒战、头晕、不适、全身无力、恶心和呕吐等症状。部分病例出现了胸部体征、影像学异常、通气功能下降和血气异常。对病例时空分布的流行病学分析支持了暴露与效应的关系。调查表明，臭氧以及可能的光气和相关的三氯乙酰氯是由紫外线印刷固化装置和用作清洁溶剂的全氯乙烯产生的有毒物质。
