| Abstract: | Aimed at decreasing the possibility of worker falling from the suspended cage while installing lining plates at high place in LNG outer tank, the fault tree analysis model is established applying the accident forecast technique of safety system engineering. The system failure reasons and results are drawn in the tree type relation diagram,then the qualitative calculational analysis is performed to find out the latent danger factors. The corresponding security measures are taken to guarantee personnel safety when using the suspended case,which achieves the goal of accident forecast and prevention. |
