Abstract: Methods to calculate effects of the accidental release of hazardous chemicals are documented in various national technical standards, guidelines and other bodies of laws. However, these standards differ in methodological concepts, resources needed and tool support. This may leave room for inconsistencies concerning results and subsequently risks figures. Although these differences complicate the point-by-point comparison of results the set of methodologies offer alternatives to scientists and practitioners when looking for most applicable approaches and potential for optimization in methodology and tool development. The proposed paper furthers the comparison of the forenamed standards in the field of explosion risk assessment. The vapour cloud explosion models base on the multi energy concept. For this a set of similar parameters (e.g., total mass in explosive range, type of an explosion, curve number) in the input data is used. In order to elaborate the variation effects on the computational results, different flammable substances are considered (hydrazine, propane, methyl mercaptan). The results are checked against their impacts on explosion risk figures. The potential risk is incredibly higher in the Russian approach. The paper gives a motivation to research the real vapour cloud explosions and compare these with the existing tools.
