In the afternoon of July 10th, Pingshan Project Department organized all professional staff to watch safety education warning films. Through the warning films, the staffs were educated to cherish their lives and correctly understand that safety is most important. The red line is the lifeline and warning line. It is the reason to grasp the bottom line of all work and adhere to the principle of "safety production, prevention first, comprehensive treatment". The principle of "Four No Injuries" is to enhance staff's safety awareness, enhance accident prevention and emergency handling ability by watching warning films, and make a long warning bell for implementing various safety measures in summer.
