Use of Software on Modeling Hazardous Substance Release as a Support Tool for Crisis Management

Today's modern society offers many new opportunities, but also many risks. Even modernization of companies cannot completely eliminate these dangers. In the smart industry, despite significant technological progress, it is necessary to work with various raw materials, including hazardous substances. It is these raw materials that will continue to pose risks in the future for industrial accidents, which cannot be ruled out. The possible release of hazardous substances can potentially have a negative impact on the environment and safety of the population. In order to deal with certain emergencies, it is necessary to allocate a large amount of funds and resources to them. The paper focuses on risk prevention in industry and the use of modern and new approaches. Specifically, it focuses on the implementation of the prevention of leakage of hazardous substances in the gaseous state from industrial facilities. The aim of the paper is to present a new approach to the prevention of leakage of hazardous substances, which provides more realistic calculations for modeling leaks and thus helps to reduce the cost of prevention. However, security in crisis management is not diminished. ALOHA CAMEO software was used for leak modeling, which the authors commonly use in practical applications and modeling in industrial enterprises in the performance of duties in the field of civil protection and crisis management. ALOHA software is used for such modeling, serving as a support tool for modeling for all crisis managers in Industry 4.0. This paper deals with the modeling of dispersion of hazardous substances with specific properties escaping from technological equipment located inside a building. This concerns the inability of the current dispersion model software to prevent the spread of the next leak inside the building containing the substance. A solution is needed to fix this problem. This issue is well illustrated by a specific example at the end of this article. The mentioned improvement of tools for simulation of industrial accidents influences the possibilities of development also in Industry 4.0. It enables more effective preparation for the management of possible accidents with regard to the appropriate spending of funds for prevention and subsequent response.
