COMPARISON OF THE RESULTING MODELS OF DISPERSION OF HAZARDOUS SUBSTANCES CREATED IN THE SOFTWARE ALOHA AND TEREX

Original language description

The article deals with the issue of accidents associated with hazardous substances, their prevention. Modeling of these accidents was chosen as a form of prevention. The production of dangerous toxic substances is currently growing, especially in the industry. The response to this trend is to introduce safer technological processes and preventive measures. These measures serve to prevent or at least reduce the risk of accidents and thus the escape of dangerous substances. To implement prevention, effective measures, and mitigation of the consequences of a chemical accident, it is necessary to know or at least correctly estimate the course and subsequent impact of the accident. Modeling programs are one of the most modern and effective tools used to illustrate the effects of accidents. These include two special software programs, the ALOHA program, and the TerEx program. The article describes the basic theoretical aspects related to the dispersion of gaseous toxic substances in the Earth&apos;s atmosphere and the extent of their harmful effects. It also compares the resulting models of both programs when entering the same input data - type and amount of hazardous substance, ambient temperature, wind speed, degree of turbidity, weather stability class, type of terrain surface. Verification of the theoretical results would be possible experimentally, provided that a design of a field test is carried out, which would take place under the same meteorological conditions as were performed when entering the model data by the mentioned programs. This would confirm the legitimacy of using special software to estimate the impact of the negative effects of chemical accidents.
