Software Products of TOXI+ Line for Calculation of Accidents Consequences and Risk Assessment

Annotation:

The first official version of TOXI+Risk software developed by STC «Industrial Safety» CJSC marked its ten years anniversary in April 2020. By now it become the main calculation tool for quantitative risk assessment of accidents and fire risk calculation at hazardous production facilities in the Russian Federation. TOXI+Risk is one of the products of TOXI+series, the works on which have been conducting since 1990s. The authors of the article recall the main milestones in the development of methodological and software support. Brief description is given concerning the current content of TOXI+ software series, the prospects for its development, and the activities conducted by STC «Industrial Safety» dedicated to the software.

TOXI+Risk 5 software package is currently based on 26 calculation methodologies of Rostechnadzor, EMERCOM of Russia, Roshydromet, industry standards of PAO Gazprom and PAO Transneft, and it allows to simulate emergency situations associated with the cloud dispersion of hazardous substances, their combustion or explosion, fire spilled liquids, jet fire, BLEVE et al.

TOXI+Water hammer software allows to simulate fluid flow in the pipeline systems of various configurations of the linear part, taking into account the difference in elevation of the route, the location and hydraulic characteristics of the elements of the pipeline system, including shutoff valves, pumps, safety valves and other devices, as well as estimate the mass of emissions of the transported substances during pipelines depressurization.

TOXI+HAZOP software tool is designed to automate the paperwork during HAZOP sessions.

TOXI+Forecast software allows to automate the actions of the dispatcher in an emergency: simulate accident scenarios with the spread of hazardous substances in the atmosphere when gas detectors are triggered, taking into account the current weather situation, inform the dispatcher and the interested parties about the forecast results (areas of exposure on the site plan, and potentially affected by them locations of people presence).
