致《职业与健康》杂志编辑部编辑同志不久前,我厂购进一台沙轮切割机,因气候因素放在一间不大的室内。每次切割铁料,磨下的金属、金刚砂树脂、玻璃纤维等粉尘飞扬,而且也没有口罩等保护用品,大家意见很大。请问:这些飞尘对人体是否有害,有毒,应怎样避免和防护,知道贵刊设有咨询服务台,祈请作答。市色织整理二厂葛登扬 1985年9月23日
To “occupation and health” editorial editor comrades not long ago, I bought a factory sand wheel cutting machine, due to climate factors in a small room. Every time cutting iron, grinding the metal, diamond resin, glass fiber and other dust flying, but also no masks and other protective equipment, we have great views. Excuse me: are these fly dust harmful to the human body, toxic, how to avoid and protect, know your magazine has an information desk, pray for answer.
