A Study on Zone-Based Risk Analysis for Complex Gas Facilities

An accident of industrial can generate damage about person and facility, because most industrials use various harmful materials such as combustible gas. Especially, deriving risk is very important for preventing and corresponding accidents. Most analysis methods have indicated risk by connecting same risk value as contour. However, those methods did not explained risk among facility in a specific area. This paper aims to propose zone-based risk analysis in order to evaluate numerically individual risk about dangerous facilities around limited area. Furthermore, this research develops zone-based risk analysis engine in order to suggest individual risk per cell called zone.
