Development of methods for modeling the dispersion of hazardous substances accidental release, improvement of the methodology for accidents risk assessment, implementation of tools for risk-oriented supervision in the field of industrial safety, and the following need for verification of the software tools and the methodological approaches used for risk assessment and modeling accidents at hazardous production facilities creates the necessity in the development of database of large full-scale experiments with the release of «heavy» gas. STC «Industrial Safety» CJSC has developed TOXI+Verify database, which includes data from foreign and domestic scientific reports making it possible to estimate the accuracy of the software complexes for modeling accidental releases for compliance with the experimental data. The parameters are given which describe both the series of experiments and each experiment, as well as the dynamics of the change in the concentration of hazardous substance and the temperature in the sensors. For the objective to verify the software designed to simulate the dispersion of emissions to the atmosphere, the command shell of TOXI+Verify database provides the possibility to call the calculation module «Master-TOXI» included in the scope of the calculation modules of TOXI+Risk 5 software package with automatic substitution of the parameters of the current experiment and saving the calculation results in the database. In general, the results of dispersion calculations with the experimental data for Burro, Coyote and Thorney Island experiments are well matched by several criteria, including those in the model assessment record. In some cases the calculations give the conservative estimate, which is related to the limitations of the methodology used to model the dispersion of hazardous substances accidental releases and some conservatism of the scenarios considered in the simulation.
