1979年2月的一天,美国S公司有95名工人,在一个狭窄,通风不良的厂房里用电熔切割器来切割核电厂的设备——冷却器。这种冷却器的盘管是用铜镍合金制造的。这些人工作不到5个小时,就有1/3的人感觉呼吸困难、怕冷、发烧,有的人还咳嗽,化验白细胞多数增高。厂医诊断为“感冒”。后来,发病者逐渐增多,才向职业病医师求诊。经过现场调查和对病人的身体检查得出结论是患了一种职业病——金属烟雾热。确诊的根据有8点:①工人所切割的管子含有90％的铜、10％的镍和少量的锌;②管子是用电热切割器切割下来的,产生近1000℃的高温,金属微粒容易和空气中的氧形成化
One day in February 1979, 95 workers at S Company of the U.S.A. used a fused cutter to cut the plant-cooler of a nuclear power plant in a narrow, poorly-ventilated factory. The coil of this cooler is made of copper-nickel alloy. These people work less than 5 hours, 1/3 of people feel breathing difficulties, cold, fever, and some people cough, test the majority of leukocytes increased. Factory diagnosed as “cold.” Later, the incidence gradually increased, before seeking medical advice to occupational disease physicians. After field investigation and physical examination of the patient, it was concluded that there was an occupational disease - metal smoke fever. The diagnosis is based on 8 points: ① The pipe cut by the worker contains 90% copper, 10% nickel and a small amount of zinc; ② The pipe is cut with an electric cutter to produce a high temperature of nearly 1000 ° C and the metal particles are easily and Oxygen in the air is formed
