Abstract
Experiments have shown the most important factor in leakage of gas pressure stations are taps. Gas leakage in industrial environment has hazardous effects.so, there is important to consider the same factors in these environments. To recognize these factors, it is necessary to represent the importance of avoiding these events by risk evaluation methods. Fault tree analysis is a method which can recognize the fault points in a system and it is able to obtain the probability of these events. To analyze the problem, fault tree of each region in the gas station is drawn. Then the data of these regions (including the probability of failure parts) are entered to FTA software. The outputs of software can be used to analyze the system. The outputs show that the most part of leakage caused by refnenet gas region which turbines are activated. Finally, some procedures are suggested for preventive of leakage in gas stations.
