Item type: Item , Mapping the hazards of transport of dangerous substances by rail(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Žitníková, Iva; Pužová, Pavlína; Bernatík, AlešThe aim of the following contribution is the mapping of hazards of transport of dangerous substances on a chosen railway stretch in the Moravian-Silesian Region. The mapping will be used for the preparation of a new module “Railway” for the prototype software system FLOREON+. The mapping focuses on railway critical points, such as level crossings, underpasses, bridges, where an increased risk of accidents exists. The contribution also deals with the issue of the most common causes of more or less severe railway accidents leading to injury and/or loss of human life and property damage.Item type: Item , Proposal for unifying the safety and security terminology at the Faculty of Safety Engineering of the VŠB - Technical University of Ostrava(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Řehák, David; Giertlová, ZuzanaThe proposal for unifying the topical safety and security terminology at the Faculty of Safety Engineering of the VŠB - Technical University of Ostrava is presented in the paper. The paper deals with the descriptions of key terms from the area of safety/ security engineering, which reflect all the specialized areas emerging from the priority specializations of this faculty and makes their comprehension and interconnection easier.Item type: Item , Protection of the national critical infrastructure(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Hadáček, Libor; Ščurek, Radomír; Cígler, JaroslavSeveral critical infrastructures have been identifi ed in the Czech Republic that when disturbed or destroyed, they would impact on the performance of the state’s functions. Failure of any such infrastructure could cause a failure of critical infrastructure in another Member State or Member States. Considering this international proportion, an integrated approach of the whole EU has been chosen to identify weaknesses, vulnerable points and gaps in protective measures. The goal of every EU member state is to protect entities and elements of critical infrastructure, prevent their disruption or their destruction, and minimize the impacts of possible failures of such infrastructures on the national and regional levels (Explanatory Memorandum, 2000).Item type: Item , Crisis management terminological synonyms(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Dvořák, Jiří; Dawson, MichaelLinguistic risks must not affect negatively the quality of risk communication. It is advisable to know synonyms of the terms belonging to crisis management lexicon together with the differences in their denotations. Seemingly synonymous terms have to be further interpreted and classifi ed according to their occurrences and combinations. The analysis of terminological synonyms may result in the need to reassign a lexical entry, which is given inappropriate prominence in the current dictionaries and terminological glossaries.Item type: Item , Basics of evaluation of thermal radiation effects on humans in industrial fires(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Dlabka, Jakub; Baudišová, Barbora; Řeháček, JakubThe issues in evaluating the effects of industrial fires on humans are very complex. One of the major factors posing a danger to humans in a fire is heat flux. There are multiple ways to evaluate these effects and each has its own specifics and drawbacks. The aim of this contribution is to analyze the basic parameters for various types of industrial fires, radiative heat transfer characteristics and the way the heat flux transferred by radiation affects human organism. Further discussed are basic means (models) to describe relationship of heat flux and its effects on exposed individuals.Item type: Item , A new approach to fire safety system in the process of atmospheric rectification of oil(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Cvetanović, Sveta; Popović, Danilo; Mihajlović, Emina; Pešić, DušicaThis paper presents the methods of detection and diagnosis of failures, that is, detecting the existence and causes of failure that can be applied in systems that operate in real time. The proposed system allows automatic and semi-automatic security management, and provides general average or minimizes the consequences of disasters. In addition, it defines the conditions, i.e. the intervals of parameter values, under which causes of failure are created. Based on these parameters, optimal design of protection is possible and it enables the efficient management of the system. Suggested fi re safety system in the process of atmospheric rectification of oil offers the possibility to choose an optimal diagnostic algorithm and its practical and economic usage. A new approach should be applied in order to reduce fire hazards in the process of atmospheric rectification of oil. Fire safety system should be inseparable from the technological process, and vise versa. The procedure recommended for fault detection and diagnosis consists of two phases. The first phase involves the assessment of the process state, while the second involves the identification of the values of processing parameters and their correlation with the process model parameters.Item type: Item , The risk of arsenic contamination in Czech urban soils(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Zimová, Magdalena; Wittlingerová, Zdeňka; Melicherčík, Jan; Závodská, Anita; Cidlinová, Anna; Němcová, Vladimíra; Danihelka, PavelArsenic (As) contamination was investigated in urban soil agglomerates in the Czech Republic. The aim of studying surface urban soil layers was to assess the degree of health risk resulting from the exposure to toxic substances through unintended consumption of soil and soil dust. Given that the greatest risk of increased exposure is for the population of preschool-aged children, the project focused on kindergarten playgrounds. Measurements were carried out in a total of 413 kindergartens in 38 towns between 2002 and 2007. Selected metals and polycyclic aromatic hydrocarbons were monitored in the surface soil layer samples of the playgrounds. This study presents the results of the soil As contamination and evaluates the health risks faced by children through exposure to these soils. Based on the results of the soil analysis and on the use of residential exposure scenarios for preschool-aged children, the oral and dermal exposures to As in children within the 1 to 6 year age group were estimated. At all monitored sites the risk was found to be higher than 1x10-6. When the overall risk of cumulative exposure to As during childhood and adulthood was evaluated, the risk of 1x10-6 was exceeded in about 99 % of the cases and the risk of 1x10-5 was exceeded in about 54 % of the cases.Item type: Item , Efficiency evaluation of protection systems using software simulation(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Vaculík, JurajArticle describes the most common methods for evaluation of physical protection systems. It analyzes various software simulations and describes how mathematical model can be used for evaluation and designing of physical protection systems and how it can provide a basis for software simulation that could upgrade possibilities and extend the scope of previous software. Author is focusing on the selection of the best approaches from the evaluation of physical protection systems designed for nuclear facilities and how these approaches can be used in evaluation of physical protection systems designed for the protection of property, persons and tangible assets.Item type: Item , Screening of platinum group metals from automobile catalysts in soils of Ostrava City(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Sikorová, Lucie; Šucmanová, Marcela; Danihelka, PavelAutomobile catalysts are sources of platinum group metals (PGM) emissions into the environment. Since their introduction, the increase of PGM concentrations in different environmental matrices has been observed. This, together with the information about toxicity of Pt, Pd and Rh, raises concerns about possible health risks. To obtain input data on potential exposure to PGM, soil sampling methodology was developed and screening of PGM in soils was provided in the city of Ostrava at locations with different traffic load, including sites with potential exposure of children. The screening indicates that in immediate proximity to high traffic, increased Pt, Pd and Rh concentrations are observed.Item type: Item , The use of modified clay materials for the sorption of various industrial pollutants(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Polzin, Hartmut; Pavlovský, Jiří; Herecová, Lenka; Míček, Dalibor; Mucha, Martin; Doležalová Weissmannová, Helena; Študentová, Soňa; Vasková, IvetaThe Authors dealt with the use of modified clay materials for the removal of dangerous industrial pollutants. Three modification methods (namely modification by Keggin’s polycation, modification by means of humic substances and pillarization at 450 °C) were applied for the creation of modified materials. Clay materials modified by humic substances were used for the sorption of Cr(VI) from aqueous medium in the form of dichromates. Other ways of modification and their combinations were used for the preparation of the sorbents of dangerous gaseous pollutants (toluene, xylene). It was discovered that some modified clay materials sorb the gaseous pollutants twice as much as common sorbent (activated carbon).Item type: Item , Calculation of fire resistance of reinforced concrete column by the zone method(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Milošević, Lidija; Pešić, DušicaThis paper describes the calculation of the fire resistance of reinforced concrete column that is exposed to fire from two sides. Calculation of the temperatures has been made depending on whether the heat flow within the reinforced concrete column is one-dimensional or two-dimensional. The temperature of concrete and the temperature of reinforcement are calculated by the Hertz's method. The values of concrete strength and reinforcement, as well as the width of the damage zone of concrete during a certain period of exposure to fire have been calculated. Resistance to the effects of fire on reinforced concrete column has been calculated by the zone method. The time of the resistance of column to the effects of fire has been determined according to the moment capacity of reinforced concrete column.Item type: Item , The application of Bayes' theorem for the need of fire technical expertises(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Dvořák, OttoThe article describes literary knowledge briefly and presents an example of the application of a statistical, probability approach to the estimations of the uncertainties of the results of the qualitative GC/MS chemical analyses of the samples of the fire debris from the seat of fire for the content of accelerants.Item type: Item , Assessment of the risks of level crossings in the Moravian-Silesian Region and proposed safety measures(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Žitníková, Iva; Schwarz, Michal; Bernatík, AlešItem type: Item , The analysis of combustion gas by method of FTIR(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Věžníková, Hana; Dubový, RomanItem type: Item , Population vulnerability evaluation against long-term floods impacts(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Šenovský, PavelItem type: Item , Application of risk analysis in the physical protection of public universities(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Ščurek, Radomír; Konečný, MartinItem type: Item , Issues resulting from the use of the crisis management terminology in the Czech legal framework(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Smetana, Marek; Zdráhal, KarelItem type: Item , Assessment of the response of prefabricated house to the explosion of gas-air mixture(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Mynarz, Miroslav; Skopal, AdamItem type: Item , Computer modelling of human situation and behaviour in fire(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Kučera, Petr; Antonín, MiroslavItem type: Item , Strength verification of accessing and rescue ladder stile(Vysoká škola báňská - Technická univerzita Ostrava, 2011) Jánošík, Ladislav; Mynarz, Miroslav
