随着工业的发展和焊接工艺的广泛应用,焊接工艺所带来的职业性危害也相应增加;如电光性眼炎、氟化物及氮氧化物所引起的呼吸道损害、锰中毒以及长期及入电焊尘所引起的尘肺等。现将我科对我局管内电焊工人检查发现的20名电焊工尘肺综合报导如下。一、劳动卫生的一般情况: 焊接工艺在我局的铁路生产中应用范围主要是机车、车辆、机械及其配件的维修。目前使用的焊接种类主要是手把电焊、近年来有些单位对固定补接的焊件逐步采用了埋弧自动焊;按其作业环境条件可分为露天、室内及容器内作业三种,其中室内
With the development of industry and extensive application of welding process, occupational hazards brought by welding process also increase accordingly; such as electrophoric ophthalmia, respiratory tract damage caused by fluoride and nitrogen oxides, manganese poisoning and long-term and electric welding Dust caused by pneumoconiosis. The report of the 20 welder pneumoconiosis reports discovered by our department on the inspection of welders in our department is as follows. First, the general situation of labor and health: Welding process in our bureau’s railway production applications mainly locomotives, vehicles, machinery and parts maintenance. The welding types currently used are mainly hand-held welding. In recent years, some units gradually adopt submerged-arc automatic welding to the fixedly-added welding pieces. According to their operating environmental conditions, they can be classified into three types of operations in the open air, indoor and container,
