如何正确挑选和使用梯具的技巧

如何正确挑选和使用梯具的技巧:

在各类工伤事故中,与梯子有关的案例非常多。每天都有成百上千的人因为使用梯子不当或者使用劣质梯子而受伤,结果造成残疾甚至死亡。因此,产品安全培训,成为防止此类事件发生、保护生命的重要途径。

梯子的种类多种多样,每一种都有专门的用途。另外,他们的材质也多种多样,有木头的,有铝的,有塑钢的等等。而且不同款式的梯子有不同的长度、承重级别和原材料,比如在带电环境下就要使用玻璃纤维做的梯子。在使用梯子之前,要仔细检查梯子的焊点、铆钉、踏蹬连接处等是否松动。如果有任何以上问题的梯子都不要使用。为了使用安全,梯子要放置在水平地面上,顶端避开上方的危险物,比如高压线等。直梯的低端要保证在75.5度安全角度,或者,保证底边和斜边为4:1的比率。最简单的方法就是用脚趾头砥住梯子角,伸直手臂,手掌能手握住梯子为好。

在攀爬梯子时,始终要保证手脚同时抓住梯子,绝不要一只手或双手扛着东西爬梯子。当梯子爬到高处时,需要让梯子高出屋顶3英尺(0.91米)。在爬梯过程中,不要过度伸展。永远保持自己的身体在梯子的两个竖挡之间。一定要爬下梯子,移动梯子,再爬上来。

但值得注意的是,仅仅培训是远远不够的,越是熟练的工人越会做危险的动作来快速完成工作。因此,安全梯子的设计理念,才能从根本上杜绝不安全的工作行为。

The production process of copper in China is dominated by copper concentrates and pyrotechnic smelting of blister copper. The status quo is that the processing capacity is greater than the smelting capacity, smelting capacity has greatly exceeded the support capacity of copper concentrate, copper concentrate resources and scrap copper imports are required. Statistics show that in the 21st century, the output of domestic copper concentrate has not been significantly increased, maintaining an annual output of 600,000 tons (copper content, the same below), by the end of 2007 will form nearly 3.7 million tons of smelting capacity, far exceeding By then China's copper concentrate resources and the protection of the capacity of the international market may provide the amount of copper concentrate. The production capacity of copper mines in China can only meet 40% of the smelting capacity.
