RISK-BASED INSPECTION METHODOLOGY, PART 3, ANNEX 3.A—BASIS FOR CONSEQUENCE METHODOLOGY 3.A-233.A.4 Level 2 Consequence Methodology3.A.4.1 GeneralThe use of event trees and quantitative effects analysis forms the basis for the Level 2 consequencemethodology provided in Part 3, Section 5 with the details for calculating event tree probabilities and theeffects of pool fires, jet fires, flash fires, fireballs, VCEs, and BLEVEs are provided. Part 3 provides theimpact of most of these events with the closed-form equations.3.A.4.2 Cloud Dispersion AnalysisSome events, such as VCEs and flash fires, require the use of sophisticated dispersion analysis software tomodel how the flammable or toxic releases mix and disperse with air as they are released to the atmosphere.There are several commercially available software packages that enable the user to perform dense gasdispersion consequence modeling. Examples include, such as SLAB, DEGADIS and PHAST, some of whichare available in the public domain, while others are commercially available. A study contracted by the U.S.Department of Energy provides a comparison of many different software packages, and recommendationsare provided to help select the appropriate package for a particular application.In general, packages that perform dense gas dispersion modeling should be chosen as opposed to neutrallybuoyant models because hazardous releases typically will be materials with molecular weights heavier thanair. Even light hydrocarbons can be modeled accurately using dense gas modeling since the temperature ofthe releases will result in releases with densities heavier than air.Dispersion models will provide a cloud concentration profile. For flammables releases, the concentrationprofile is used to assess which portions of the cloud are in the flammable range. For flash fires, the impactarea at grade is determined to be the area in the cloud that has flammable concentrations between thereleased fluid’s LFL and UFL. For VCEs, a volumetric calculation is required since the total amount offlammable volume and mass is required to assess the magnitude of the explosion.3.A.5 Consequence Methodology For Atmospheric Storage Tanks3.A.5.1 OverviewThe consequence model for atmospheric storage tanks (ASTs) is based on a modification of the Level 1consequence analysis. Only a financial consequence analysis is provided for the AST bottom.3.A.5.2 Representative Fluid and Associated PropertiesA representative fluid that most closely matches the fluid contained in the AST system being evaluated isselected from the representative fluids shown in Part 3, Table 6.1. The required fluid properties for theconsequence analysis are also contained in this table.In addition to selecting a fluid, a soil type must also be specified because the consequence model dependson soil properties. Representative soil conditions and the associated soil properties required for theconsequence analysis is provided in Part 3, Table 6.2.
