At the present, a variety of models exist to estimate themagnitude of the consequences of different types of accidents, most of them having an empirical basis.These models aren't for exclusive use in industrial facilities and can also be used for consequences analysisin for example chemical or petroleum industries or in environmental impact studies. Although a wide variety of mathematical expression are available for events ad unconfined or confined explosions, liquid spills or gas leaks, releases of hazardous materials, BLEVES or fires, few simulation packages exist that can assist anon-specialist in decision making related to consequences analysis. In general, existing simulation packages are not freely available for undergratuatestudents due to the costs, accessibility or requiredknowledge.This paper describes the development of a didactic tool for the simulation of accident consequences, for academic and free use in the Departamento de Ingegneria Mecanica e Industrial of the Univeridad Nacional Autonoma de Mexico. The software is being developing using Visual Basic, as this is a widespread developing platform, easily accessible and quick to assimilate among the students of the different disciplinary areas of the engineering faculty.
