吸入氧化锌烟雾引起的金属烟雾热,早有许多报导,但是由氧化锌烟雾所致眼部的损害报导比较少见。1976年9月某保温车辆段电焊工,焊接镀锌铁板,发生六例眼部损害,现将调查结果报告如下: 一、劳动条件调查电焊工应用ZB300二氧化碳焊机,焊接镀锌铁板。焊接时没有固定焊台,就在检修车间过道处焊接,没有防毒设备。每天有2~3个焊工,焊接保温车底1~2节(8~10块镀锌铁板焊接一起为一节)。镀锌铁板是西德进口,焊丝是北京特钢生产的特种钢丝。焊工只带有色防紫外线的面盾,不带口罩两个焊工同时焊接,产生大量的白色烟雾,在焊缝两旁沉积一层白色粉末,很轻,一触即散,随
Much has been reported about inhalation of metal smoke heat caused by zinc oxide fumes, but reports of eye damage caused by zinc oxide smoke are rare. Sept. 1976 A welder in a thermal insulation depot, welding galvanized iron, six cases of ocular damage, the findings are reported as follows: First, the working conditions survey Welder ZB300 carbon dioxide welding machine, welding galvanized iron. There is no fixed welding soldering station, welding shop in the overhaul workshop, there is no anti-virus equipment. Every day there are 2 ~ 3 welders, welding insulation bottom 1 ~ 2 (8 to 10 galvanized iron welding together as a section). Galvanized iron sheet is imported from West Germany, the wire is a special steel wire produced by Beijing Special Steel. Welder only with a color UV shield, without a mask welding at the same time two welders, resulting in a large number of white smoke deposited in the weld on both sides of a layer of white powder, light, touch, with the
