金属烟雾热(MFF)既往称之为“黄铜铸工热”,本文报导一起由于在密闭无通风装置的密闭室内用电割枪切割铜管,导致金属烟雾热的暴发。1979年2月建筑公司承包一家电力公用事业公司在蒸气冷凝器内更换冷却管,该冷凝器约45000立方英尺,并由一个金属壳完全密闭,在壳上切割似门一般大的入口。2月9日工人日、夜轮班用电锯拆冷却管,次日早、晚两班改用电焊枪(碳气)切割。用电锯拆冷却管均未发病。改用焊枪切割的26人中25人发病。工人均不戴呼吸器。潜伏期(自开始用焊枪到第一个出现症状)算术均数、中位数皆为5小时,范围1～10小时。病程(指开始出现症状到症状完全消失)7—120多小时,据21人计算,病程平均
Metallurgical Fog (MFF), formerly known as Brass Castor Heat, was reported in this paper as a result of the thermal outbreak of metal smoke caused by the cutting of copper tubing with electric torches in a closed, airtight, non-ventilated room. February 1979 Construction Company Contracts An electric utility company to replace a cooling tube in a vapor condenser, which is about 45,000 cubic feet and is completely enclosed by a metal shell, cutting a portal-like entrance to the shell. February 9 workers Day, night shifts with power saw cooling tube, the next morning and evening switched to electric torch (carbon gas) cutting. Saw with electric saw cooling tube were not affected. Twelve of the 26 people who switch to welding guns were involved in the disease. Workers do not wear respirators. Latency (from the beginning with the first appearance of a torch) arithmetic mean median of 5 hours, the range of 1 to 10 hours. Course of disease (refers to the symptoms began to completely disappear) 7-120 hours, calculated according to 21, the average duration
