“…The risk assessment procedure is based mostly on the chance of the detected risk occurring, and its potential risk implications are specifically analyzed through hypothetical scenarios of accidents [2]. Concerning the proposed project, a risk matrix designed to integrate risk severity and probability factors has been used to primary hazards such as jet fire resulting from natural gas pipelines failure [25]. The risk connected with the natural gas distribution network was semi-quantitatively evaluated by employing order of the magnitude data as a product of probability and seriousness/consequence (risk rate = severity/consequence factor × probability factor) [25].…”

Risk assessment is one of the main tools that oil and gas industries use to assess the hazards and risks in their facilities worldwide. Qualitative and quantitative risk assessments are carried out at various phases of the process industry: conceptual stage, design stage, construction stage, operational stage, decommissioning stage, etc. The quantitative risk assessment is directed during the detailed design stage to decide the spacing and layout out of equipment for safe operation and maintenance of oil and gas industries. The equipment layout and spacing are based on the safe distances are to be carried out on various design safety studies. In this work, a study was carried out on upstream onshore natural gas gathering stations and associated equipment and pipeline networks. The fire, explosion assessment, and toxic gas dispersion are conducted to evaluate how it affects people, assets, and the environment. Whether the design protection systems are adequate to mitigate the consequences or any additional measures to reduce risk to an acceptable level is analyzed.

“…Two weak points of this research were the lack of definitions and background of the research. Vairo et al (2021) examined the risk assessment aspect of natural gas lines. By investigating historical accidents in NG pipelines in the United States, Canada and the European Union, they concluded that the critical factors causing these accidents included the failure mode, immediate and root cause, evolving scenario, degree of confinement produced by the surroundings and ignition timing.…”

Industrial accidents have increased the importance of dealing with the risks of toxic exposure, fire and explosion. Despite the measures taken in the chemical industry to prevent accidents, the accidents occur often due to human error or process faults during repairs. Although several studies have been conducted on the accidents in the process industry, no research has modeled the risks caused by the leakage of toxic substances in the gas pressure reduction station. The consequences of gas leak and fire in Zahedan's gas pressure reduction station were investigated in Iran. This research aims to determine the safe range of the station and observe the safety measures required for the gas pressure reduction station in Zahedan. For modelling gas leak and fire, the ALOHA software was used to display the threat zone. In this research, with respect to the environmental data, the desired scenario was modeled. The results, based on two scenarios of gas leak and fire in both hot and cold seasons, indicate that the gas leak scenario in hot seasons and the fire scenario in cold seasons influence a larger region.

The high-temperature molten metal leakage accident and its secondary accidents have become urgent problems to be solved in the current metallurgical industry because of their destructive power. The description of the high temperature molten metal leakage accident structure is the basis for studying its evolution law. Based on the idea of collection, this article uses multiple case analysis methods to abstract the accident attributes, and constructs an accident institutionalized description framework with the content of accident types, internal attributes, environmental attributes, management attributes, and hazard assessment attributes. A structured description of the leak. Finally, the “4.18” ladle capping accident of Qinghe special steel in Tieling, Liaoning Province was selected for example verification, and the attribute relationship between the primary accident and the secondary accident was analyzed. The research results have reference value for studying the evolution law of high temperature molten metal leakage accidents and making emergency decisions.
