The paper deals with the protection of the population and the environment in crisis management and emergency planning. It includes a proposal for an auxiliary tool for crisis managers and commanders to increase the safety of the population and the environment in the evaluated area. The proposal was developed thanks to a detailed analysis of the border area in selected regions of Slovakia, where extraordinary events may occur during the cross-border transport of hazardous substances. The actual outputs are maps of area-border crossings, including the places of transport of hazardous substances specifying a range of possible adverse effects on the endangered area. The modelling process was based on real conditions in the given area. Various scenarios of the possible occurrence of the release of hazardous substances were developed. The scenarios were applied in the ALOHA CAMEO software. Using the software output, it was possible to draw the most probable emergency scenarios with a cross-border effect. Cross-border impacts are crucial challenges in dealing with an emergency, as there is a need to ensure cooperation and coordination of emergency services in two different countries. The outputs proposed by the authors are a tool suitable not only for taking preventive measures but also as an aid in repressive activities. It is, therefore, suitable both for reducing the probability of the occurrence of given emergencies and minimizing its consequences.

Categorization of enterprises by size provides a fundamental understanding of the composition of the business environment. Small, medium-sized, and large enterprises play a significant role in the national economy through the execution of specific business activities. In their pursuit of enhancing the efficiency of individual business processes and mitigating the risks associated with these activities, enterprises may implement various ISO standards, including quality management, environmental management, occupational health and safety (OSH), or corporate social responsibility (CSR) systems. The sources published to date do not clearly explain the mutual relationship that arises when implementing multiple ISO standards that prioritize different activities within a single enterprise. This gap is particularly evident in the context of small enterprises, which often do not have the obligation or capacity to implement ISO standards. This study addresses this research gap by identifying the relationship between implemented ISO standards, priority activities in the risk management process, and the person responsible for these activities. The objective of this article is to examine the relationship of dependency between specific ISO standards and the priority activity in risk management. Furthermore, the study seeks to determine whether the degree of implementation of ISO standards influences the selection of the person responsible for risk management. Additionally, it examines whether dependence exists between the priority activity in risk management and the specific person responsible for risk management. The authors provide statistical hypothesis testing based on data from a nationwide survey conducted across all enterprise size categories. The results obtained from this study confirm the presence of a dependency between the degree of ISO standards implementation and the priority activity in risk management across all enterprise size categories. However, a statistically significant dependency between the degree of implementation of ISO standards and the person responsible for risk management was not confirmed in large companies. The dependency between the selection of the person responsible for risk management and the priority activity in risk management was confirmed only in small enterprises.
