The role of software tools in risk assessment got froman accident and emissions of hazardous materials

The development of atmospheric dispersion models is an important step in the process of predicting, assessing and managing the risk of potential disasters. They are of particular importance in defining and analyzing risk zones in order to prevent endangering a large number of people, property, the environment and natural resources. Today, making a model is almost unthinkable without the use of appropriate software solutions. Numerous software tools for atmospheric dispersion modeling have been developed, the primary role of which is risk assessment, which includes the analysis of accident and emission pollution models used to simulate the transport and diffusion of various pollutants. As many industrial and development projects potentially cause unwanted consequences in the environment, by applying such tools the harmful consequences could be minimized. The development of sensor and computer technology has enabled the development of complex algorithms for the development of models that can be executed in real time, which enables their active role in managing the process of responding to an incident that has occurred. This paper presents the possibilities of modelling software tools through the example of the impact of chemicals on the environment in the case of emissions of hazardous gases due to an accident. The characteristics of the mathematical model and the simulation scenario made in the Aloha software tool are presented
