打光工人

With the help of cooperative companies, labor unions, management, and workers, we know that when any form of beryllium is milled, lathed, deburred, sanded, polished, or otherwise machined, it liberates micron- and submicron-sized particles that deposit deeply and invisibly in the lungs.

在能合作的公司、工会、管理人员和工人的帮助下，我们知道了，当任何形式的铍被铣过，用车床加工，除毛刺，砂打，抛光或用其他方式加工的时候，这个过程释放了微米和亚微米级的含铍粒子，无形地深深地沉积在肺中。
