某造船厂电焊工10余人,于密闭的舱室内从事锌焊接作业。下班回家后,他们无一幸免地均在当夜骤起恶寒战栗,继而发热,并有头昏、乏力和咳嗽等症状。为何10余人会同时出现身体不适呢?经有关专家诊断,这些人所患疾病叫“金属烟尘热”,究其原因,是由于作业环境通风不良,作业人员吸入了过多的金属烟尘所致。 A shipyard welders more than 10 people, in airtight cabins engaged in zinc welding operations. After returning home from work, they were all spared no evil in that night a sudden chills, then fever, and dizziness, fatigue and coughing and other symptoms. Why do more than 10 people have physical discomfort at the same time? The experts diagnosed the diseases they called “metal soot fever”. The reason is due to poor ventilation in work environment and the operators inhaled too much metal dust.
