我厂是一个综合性碳素制品厂,主要原材料是焦炭、炭黑、石墨、沥青、煤焦油、苯、铜粉、银粉、铅粉、锡粉等。在生产过程中经过煅烧、破碎、磨粉、熬煮、混合、压型、焙烧、石墨化、切削加工等工艺过程,要产生大量粉尘和烟气;尤其是沥青和煤焦油熬煮产生的大量黄烟(其中含有致癌物质),严重危害人身健康;加之自动化程度低,手工操作多;因此,劳动条件的特点是“黑、热、累”。特别是石墨化工序,粉尘浓度高达每立方米624毫克,超过国家标准六十倍以上。所有窑炉都是人工装出
Our factory is a comprehensive carbon product factory. The main raw materials are coke, carbon black, graphite, asphalt, coal tar, benzene, copper powder, silver powder, lead powder, and tin powder. In the production process, a large amount of dust and smoke are generated through the processes of calcining, crushing, grinding, cooking, mixing, pressing, roasting, graphitization, cutting, and the like; especially, asphalt and coal tar are used for cooking. Yellow smoke (which contains carcinogenic substances) seriously harms human health. In addition, the degree of automation is low and many manual operations are performed. Therefore, the characteristics of labor conditions are “black, hot, and tired”. In particular, the graphitization process has a dust concentration of up to 624 mg/m3, more than 60 times the national standard. All kilns are manually loaded
