Study On The Gas Pipeline Construction Safety Management System Of The Third Party

To some extent, the city gas brings threat to the public order and safety of life andproperty life and property safety of the residents. Third-party gas pipeline construction areserious threats to pipeline damage accidents, it’s effective to reduce the probability of anaccident by developing a pipeline control method targeted for the risk factors from thethird-party damage. In the paper, several researches are carried out based on risk identificationand risk control basic theory.The various factors of third-party construction accident are analysised through FTA,various combinations of the causes of the gas accident are determined by a fault tree. Theimportance of risk factors in order comes from the minimal cut sets of Third-party damageaccidents which are the results of calculation via Boolean algebra method.Human risk factors caused by the third-party damage to city gas pipeline network areclassified, correlation is the result the calculation which bases original data of the third-partydamage. Finally, primary and secondary relationship of derived human risk factors isobtained.A city-based data of the third-party damage accident on risk control model is solved, theconclusion is a stable security control and risk index and a third-party damage accident ratecurve of the gas pipeline network of the city.
