矽肺的发生和空气中粉尘浓度高低,以及粉尘中游离二氧化矽含量,有着密切的关系。为了评价综合性防尘措施效果,为国家制定卫生标准提供科学依据,为加强和提高防尘工作质量,更好地保护工人健康;遵照伟大领袖毛主席关于“人类总得不断地总结经验”的教导,现将鞍钢耐火材料厂矽砖车间,历年来粉尘浓度、矽肺新发病率及发病工龄等资料,进行初步整理,扼要地分析报告如下。
The occurrence of silicosis and the level of dust concentration in the air, as well as the free silicon dioxide content in dust, has a close relationship. In order to evaluate the effect of comprehensive dust control measures and provide scientific basis for the formulation of national hygiene standards, in order to enhance and enhance the quality of dust-prevention work and to better protect the health of workers, in accordance with the teachings of Chairman Mao, the great leader, that “mankind should constantly sum up experiences” , Anshan Iron and Steel Refractories plant now silicon plant, over the years the concentration of dust, silicosis new incidence and length of service and other data for preliminary sorting, concise analysis report is as follows.
