随着工业的发展,铁路运转的矿石装卸量日渐增多,装卸工受粉尘危害也再加重。为进一步调查接触粉尘对装卸工人的危害,搞好防治工作。现将我分局重点装卸矿石二十余年的两个车站,从劳动卫生学调查和121名接触粉尘装卸工人健康状况的动态观察资料报告如下。调查方法一、生产环境中粉尘的测定测定粉尘浓度采用滤膜计重法;测分散度采用滤膜涂片法;测游离二氧化硅含量采用焦磷酸重量法。二、肺功能测验采用上海红卫医疗器械厂生产6升单筒肺量计,测三项通气功能指标。测前做好训练,固定一个人操作到底。
With the development of industry, the loading and unloading of railroad running ore is increasing day by day, and the loading and unloading workers are aggravated by dust. In order to further investigate the hazards of contact dust to the loading and unloading workers and do a good job in prevention and control. Now my branch focus on loading and unloading ore two stations for more than 20 years, from the survey of labor hygiene and health status of 121 contact with the dust handling workers reported the following observations. Survey methods First, the determination of dust in the production environment Determination of dust concentration using the filter weight method; measured dispersion degree using the filter smear method; measured free silicon dioxide content pyrophosphate gravimetric method. Second, the lung function test using Shanghai Hongwei Medical Equipment Factory production 6 liters single cylinder spirometer, measuring three ventilation function. Test well before the test, a fixed operation in the end.
