Consider that your hazard analysis process resulted in the fault tree in the figure. As safety engineer your assignment is to perform an event tree analysis process for a part of the fault tree. The events on the fault tree, starting at the top, are: A, then on the left-hand side: B1, C3, Z1, Z2, C4, 75, 76, 211, Z12, C6, Z7, and Z8, and on the right-hand side: B2, C3, Z3, Z4, C5, Z5, Z6, 29, C6, 210, Z7, and Z8. You can enlarge the figure to better identify the events on the tree. If you consider that the top-level gate changes from AND to OR, you will need to develop an event tree analysis process for the branch A B2 C5 C6 Z8. The initiating event is Z8 (which has a probability of occurrence of 0.05), and B2, C5, and C6 are intermediate events (with respective probability of occurrence of 1.4 x 102, 2.5x 103, and 1.8 x 10%3). 1. Build the event tree diagram for the branch A B2 C5 - C6 Z8 2. Calculate the probability of failure on the event tree diagram of question 2 \\l- i _1_ ] st oy . Fr __l_.__ ey : 1 1| ! 3 ..'
