Natural hazards pose an increasing threat to society, necessitating the development of effective early warning systems (EWSs). This paper explores their critical role in mitigating the impacts of natural hazards. Its primary objective is to define and categorise the components of EWSs, summarise the components of existing systems, and propose a framework for a comprehensive early warning system. This paper includes a thorough review of the available scientific literature on early warning systems, natural hazards, and their underlying causes. It identifies both primary and secondary causes of selected natural hazards, along with their manifestations. Particular emphasis is placed on the significance of sensors and modern technologies for real-time data collection and processing. Based on this analysis, a framework is proposed that integrates various data sources, technologies, and components to enhance preparedness. The findings highlight the necessity of a holistic approach to early warning systems, one that accounts for different types of disasters and the specific needs of at-risk populations. The proposed framework may serve as a foundation for further development and the implementation of more effective early warning systems.

The risk assessment of the area, with emphasis on the transport infrastructure, is dealt with in this paper. Disruption of some elements of transport infrastructure can lead to major negative impacts on the functioning of society, economies or...

This paper focuses on the testing and evaluation of special anti-chemical protective suits. The testing and evaluation focused on the subjective aspect of the protective suits, which is best perceived by their wearers; however, the subjective aspect only accounts for a certain proportion of the overall evaluation. For this reason, the proposed objective evaluation criteria are also presented in the thesis. Four types of anti-chemical protective suits were selected for testing. In this way, it was possible to compare their design specificities. An older type of civil protection suit and three modern types were selected for evaluation. Multi-criteria decision making and the expert method were used to develop the criteria. Mathematical relationships were used to evaluate the test results. A methodological procedure was developed to integrate the established subjective criteria in order to test. The results of the testing confirmed the construction and design advances of the protective suits over the older type of civil protection suit. At the same time, they pointed out possible shortcomings in the work and execution of the movements of the individual selected protective suits. By evaluating the data obtained, the most suitable protective suit was selected that best met the subjective criteria. However, these results need to be supplemented by an assessment of the objective criteria in the final evaluation. This paper also presents the characteristics of the selected protective suits in terms of technical parameters and objective criteria. The results of the study can further serve as a complementary way of evaluating the quality of protective suits. It is the subjective evaluation that is essential in a comprehensive assessment of the quality of protective suits, as the user himself often perceives the quality of the product differently from the manufacturer.

The research presented in paper has focused on design of the transportation evacuation during a special flood caused by an accident at a water structure using GIS-enabled network analysis. Freely available population and address point data were used to calculate the number of residents at risk. Three scenarios of time required for each evacuation activity were determined using the PERT method, and the time required for evacuation was determined using a Gantt chart. The approach proposed in the paper is suitable for obtaining relatively quick results that can be taken into account when preparing for crisis events. The results of the case study proved that the evacuation can be carried out in the necessary time, but revealed possible shortcomings of the proposed approach. These shortcomings are discussed along with possible alternative solutions and other factors influencing the evacuation planning process.
