The Model of HSE risks in gas transmission lines by combining Meta-synthesis and fuzzy DEMATEL methods

Today, issues related to health, safety, and the environment have become an integral part of every business and organization. Therefore, the purpose of this study was to identify and prioritize HSE risks in the transmission lines of Chaharmahal and Bakhtiari Province Gas Company by Meta-Synthesis and fuzzy dimethyl methods.

In the qualitative section, data were collected using the seven-step "Barso and Sandlowski" meta-Synthesis method. The qualitative statistical population included articles and researches in the field of research between 2000 and 2021. Finally, 26 researches related to purposive sampling were selected. This research was conducted in 2023.

After documenting these studies, 627 open source codes were identified in the form of three main criteria and eleven sub-criteria, including: safety criteria (performance and lack of equipment, leaks and overflows, falls and falls, Professional quality of human factors, environmental factors, levels and harmful substances and incendiary agents and shocks), health (physical and human injuries and workplace challenges) and environment (air pollution, pollution Soil and water pollution) and The quality of the research was measured by Laosheh methods with a value of 0.81 and the reproducibility index with a value of 0.81 and finally the research model was designed using MAXDA software.

The results showed that the professional quality of human factors, physical and human injuries, and performance and lack of equipment had the highest priority, respectively and Also, the professional quality of human factors was the most influential) Cause (and physical and human injuries were the most influential (Effect).
