Risk analysis in petroleum stations in Sana'a using geographic information systems.

Abstract

This study aimed to analyze and manage risks in petroleum stations in the city of Sana’a using geographic information systems techniques, by examining the historical development of the stations and their risks, the extent of application of regulatory controls and procedures to choose their construction sites, their commitment to safety and security standards, evaluating the efficiency of the distribution of facilities necessary to manage their risks, and highlighting The risks expected to occur in order to present a proposal to manage them. This study followed a systems analysis approach in analyzing data, creating maps, and analyzing them using geographic information systems, with the aim of understanding the spatial organization of the spatial phenomenon and finding a solution to the problem.

Reliance was also made on the descriptive analytical method, which depends on studying the phenomenon as it exists on the ground, and then describing and analyzing it in order to infer the problem under study, as well as on the quantitative method and mathematical treatment of the details of the subject within the limits of the data obtained from the field study, which It was built mainly on data collected in the field, and included two main sections: a comprehensive inventory of petrol stations, civil defense centers, ambulances, and police in the city. This stage was followed by the use of a base map of the city. This study relied mainly on spatial data in determining the location through a system device. GPS location determination Which shows the locations of petrol stations, and the locations of civil defense, police, and ambulance centers and then transfers them on a map of the city, and the second is based on continuous observation and field visits to measure safety standards and controls and the conditions for establishing those stations, and the extent of their application on the station grounds, and personal interviews with some of the workers and owners of the stations for the purpose of providing us with information. necessary and required by the study.

  This work contributed to building a service database, some of its data was represented in the maps contained in the body of this study, and one of its most important results was that the spatial distribution pattern of these stations took the clustered type and did not take the organized form because their establishment was linked to the desires of investors and not linked to regulatory restrictions and requirements. Most of them were not subject to occupational safety and security standards, due to the hazardous materials they contain, which exposes the population to danger and leads to poor service, in addition to the lack of a unified system to determine the expected risks from the spread of stations, and that the geographical impact of explosion risks differs from the risks of ignition, leakage, and pollution The applications of information systems in risk management in petroleum stations in the city were also reviewed, by applying planning standards and comparing them with the current situation, revealing the presence of a deficiency and defect in the distribution of facility locations.

  The study concluded with a number of recommendations, including: introducing geographic information systems technology into national plans for risk management in petroleum stations, increasing prevention and safety measures in stations that are out of service for emergency centers, addressing the imbalance resulting from the shortage of these facilities in the city, and creating a national risk guide.
