关于钢铁工人的能量消耗,国内已有一些报告,但其中缺少吊车工人的资料。由于我们在研究鞍钢初轧厂钳式吊车作业的劳动卫生问题时,需要了解吊车操纵工人的劳动强度,故专门对此种作业工人作了能量消耗的测定。 本测定所用的方法系Douglas-Halda-ne氏法。受试者为17名健康男性钳式吊车操纵工人,年龄为25—36岁,本职业工龄均在5年以上。在采样前受试者接受佩戴采气口罩5—10分钟,使其呼吸动作适应于戴口罩,然后在劳动5分钟后取样。休息时的样 There have been some reports on the energy consumption of steel workers in China, but there is a lack of information on crane workers. Because we need to know the labor intensity of the crane operators when studying the labor hygiene problems of Anshan Iron & Steel rolling mill clamp-type cranes, we measured the energy consumption of such workers. The method used in this test is Douglas-Halda-ne’s method. The subjects were 17 healthy male clamp-type crane operators with a working age of 25-36 years and a working age of over 5 years. Subjects were asked to wear a gas mask for 5-10 minutes prior to sampling to adapt their respiration to a mask and then sampled after 5 minutes of labor. Kind of rest
