Abstract

In order to prevent natural gas pipeline construction accidents, causes of 32 natural accidents of such were analyzed by using "2-4" model causal factor coding system.16 causal factors involved in the accident were obtained through statistical analysis of 29 factors at 4 levels, and 5 most frequent ones were analyzed in detail. The results show that for all investigated accidents, the major reasons for them are personnel's faulty operation from the category of illegal and unsafe operation, inconformity of external conditions before construction with requirements from unsafe states, insufficient mastery of equipment and material characteristics from safety knowledge, failure to realize importance of construction procedures from safety awareness, unreasonable deployment of on-site safety supervision personnel from safety management structure defect, and continuous rain from natural factors. © 2020 China Safety Science Journal.
