Loboichenko V. Engineering and technical methods of prevention of man-made emergencies at low-tonnage production facilities by identification of aqueous solutions

The paper solves an important scientific and practical problem in the field of civil protection, namely, engineering methods to prevent emergencies of man-made nature at low-capacity production facilities by identifying chemicals in soils and groundwater were developed. They are designed to prevent man-made emergencies and reduce the number of consequences of these emergencies of the first and second priority levels and prevent the escalation of these situations to the local (object) level of the spread of danger Mathematical models for detecting negative factors of accumulation of chemicals in the soils of low-tonnage production facilities and the ingress of chemicals into groundwater near low-tonnage production facilities have been developed. The results of checking the reliability of the developed mathematical models and the proposed engineering methods are presented. The development and schemes of two original laboratory installations for verification of the developed mathematical models and engineering methods are described. The results of all field experimental studies coincide with the results of simulations, fit into confidence intervals calculated with a probability of 95% by Student's criterion, which confirms the reliability of the developed mathematical models, as well as the reliability of engineering methods of preventing man-made emergencies. Examples of application of mathematical models and engineering methods on separate objects of low-tonnage production were studied which are offered to use in all divisions of the SES of Ukraine of local and regional levels of subordination in the interests of prevention of emergencies of technogenic character and optimization of prevention of their occurrence on places are considered.
