石灰(氧化钙)为白色无定形物质,含有杂质时呈黄色或浅棕色,广泛用于建筑、钢铁制造、炼铝、玻璃和造纸工业。生产过程中产生的粉尘,对工人有强烈的刺激作用,对呼吸系统造成损害。为了制定我国车间空气中氧化钙(石灰)粉尘卫生标准提供科学依据,我们对杭州钢铁厂石灰车间进行了凋查研究,结果报告如下。资料与方法1．石灰车间劳动卫生学凋查:了解生产流程、 Lime (calcium oxide) is a white amorphous substance, yellow or light brown with impurities, widely used in construction, steel making, aluminum smelting, glass and paper industry. Dust generated during the production process has a strong stimulating effect on the workers and causes damage to the respiratory system. In order to develop a scientific basis for the hygiene standards of calcium oxide (lime) dust in the air of the workshop in our country, we carried out the investigation on the lime workshop of the Hangzhou Steel Plant. The results are reported as follows. Data and methods 1. Lime workshop labor hygiene investigation: to understand the production process,
