Selection of the risk sources and their assessment in the explosives operations
Hajný, Vít ; Tabas, Marek (referee) ; Kotek, Luboš (advisor)
The Master´s thesis concerns with the choice of sources of risks and their evaluation with storage of explosives. It is divided into four parts. The first two parts are research ones and they deal with accesses to the choice of sources of risks with storage of explosives and statutory requirements for explosives, their storage, manipulation and transport and then with the buildings, which the explosives are stored in. In the next part the accesses to selection and evaluation of sources of risks in real storage units are chosen and compared. In the final part there is the chosen methodology used in case studies.

Wood defects as the primary causes of the accident
Lavický, Miloš
This paper describes two specific cases of accidents for which the analysis, carried out in the expert opinion, showed that wood defects are the probable primary causes of structural collapses. The first case is a collapsing wooden work platform used as a scaffold for the construction of a masonry elevator shaft. The second case is a failure of the mounting support structure of the composite ceiling structure of the ceramic-concrete beams with spatial reinforcement and MIAKO ceramic blocks.

Point Pleasant bridge collapse - casual analysis of the accident
Jagoš, Jiří ; Němec, Karel (referee) ; Válka, Libor (advisor)
The bachelor thesis is focused on the analysis of the causes of the accident of the Silver Bridge, which occurred in 1967, forty years since the introduction of the bridge to the traffic. In the work are discussed in detail all possible causes of the collapse of the bridge on the basis information and facts mentioned both directly in the inquiry reports of committees, as well as in documents and literary sources, dealing with material analysis of the structural nodes of the wrecked bridge. The work carried out critical analysis of the available and relevant information about the crash. The bachelor thesis outlines also the possible causes of the fall and collapse of the bridge from structural point of view and from terms of the material.

Estimation of the potential consequences of the release toxic substances
Hajný, Vít ; Kotek, Luboš (referee) ; Tabas, Marek (advisor)
This bachelor thesis is concerned about the estimation of possible impact during the toxic material escape and it is devided into three parts. The first of them contains description of the significant accidents connected with this escape in the Czech republic and in the world. It includes also description of CEI (chemical exposure index), which determine the estimation and there is described the ALOHA (Areal locations of hazardous atmosphere), program whereby we can compare results. The second part is performed an identification and choice of typical accidents. In the last, practical section, are made estimates of potential consequences and their comparison.

The role of material sciences in solving the problems technical accidents
Tonkovič, Miroslav ; Řičánková, Veronika (referee) ; Klakurková, Lenka (advisor)
Material sciences plays an irreplaceable role in explanation of various technical accidents. The proposed work focuses on examples of sever chosen technical accidents in which the knowledge of materials science was crucial in use and help to solve them. Description of an incident is stated to particular cases as well as results of these investigations, taking in mind the given topis of proposed work. The accidents are always described with necessary theoretical basis connected to each particular issue. Its knowledge was undoubtedly essential in solving the accident. The end of the work is a summary of the most frequent causes of technical accidents.

Safety Management System for Transport of Materials and Dangerous Substances
Pirner, Adam ; Huzlík, Jiří (referee) ; Adamec, Vladimír (advisor)
My bachelor thesis is dealing with the dangerous substances transportation system. I used domestic as well as foreign literature sources over the past fifteen years. A part of presented sources were elaborated with help of the Study and Scientific Library Hradec Kralove according to the theme and key words. My thesis focuses on fundamental phrases connected with dangerous substances as well as the present valid legislation regulating the issue of dangerous substances transportation. Identification of dangerous substances and their qualities evaluation follows. This is essential both for common usage and for successful intervention in case of emergency and possible leak. The second half of my thesis is mostly dealing with dangerous substances transportation systems, means of transportation that conduct this activity and fire protection squads intervention during such emergency situations. Finally, there is presented own insight onto the given issue.

CHEMICALS MANAGEMENT IN THE COMPANY PRIMAGRA,a.s.
GAIGEROVÁ, Petra
Abstract The protection of the population against the consequences of major accidents in recent years has been a very important issue to deal with. As well as hazardous chemicals which we encounter in our everyday life, intentionally or unintentionally. Therefore I have chosen the theme, which deals with the effects of hazardous chemicals and the possibility of accidents caused by hazardous substances. Another motivation for the selection of the topic of this work is that I have been working as head of the laboratory in a chemical plant for several years and proper handling of chemical substances has become an everyday necessity, as well as improving prevention of our company. Most of the people associate industrial accident with the Ukrainian Chernobyl nuclear plant disaster or a chemical plant in Seveso, Italy. The releases of hazardous substances into the environment are frighteningly common in the Czech Republic as well. The main aim of this work is to determine possible impacts of the effects of individual hazardous substances on the Primagra Company, a.s. Considering this aim, the main research question has been raised: Which hazardous substances in the Primagra Company, a.s. can cause accidents? Based on this issue, further practical parts of the next target can be defined: simulation of the accident in the Primagra Company, a.s., threats to the object and possible accidents. The thesis is divided into two parts: the first theoretical part is followed by the introduction of the Primagra Company, a.s., by the sort of stored substances and modeling that is important for finding possible impacts on the accident. The introductory section summarizes the basic information concerning major accidents, legislation and examples of accidents that are associated with the release of hazardous substances in the past. Regarding the topic of the work, the thesis describes features of hazardous chemicals, labeling and packaging of the chemical substances and preparations, documentation of hazardous chemicals and important physical properties associated with the management of hazardous substances. The significance of the second part is the implementation of the simulation, also known as modelling of a chemical accident associated with hazardous chemicals. Primagra Company, a.s. became a selected plant where several hazardous substances were treated at once. For the purpose of modelling, methanol was used as a substance. TerEx was used as a simulation software tool. By using this program two emergency situations were modelled. The type of model Bleve was used, which is suitable for the hitting of the tank by fire and subsequent destruction. The bulk of the tank contents then escapes into the cloud of gas and vapor of the liquid, which is rapidly mixed with the air. Subsequent fire has risen sharply due to turbulence and mixing with air. The result is a rising ball of fire - ie. Fire Ball. It is possible to conclude from the modeled results and outputs that a dangerous cloud reaching 145 m from the site of an accident would occure. It could cause mortality of 10% within the distance of 145 m. There would be a risk of burns 1 degree within a distance of 375 m. Recommended evacuation distance by reaching 375 m. By the analysis, it was found, that in the case of an accident in the company Primagra, a.s. employees, the population in the surroundings, the environment, property of the company may be affected. The company would suffer a loss in a business field, such as loss of customer interest, direct material and production decrease. More serious impacts that would implicate in human lives would not occur, however. This work may either be used in the company Primagra Company, a.s. as a protection against accidents or as a study material.
