The urgent and follow-up precautions in case release of ammonia - back analysis of past cases
CHOCOVÁ, Lenka
For this final paper, I chose a rather serious topic that is very topical in our society. Hazardous chemical substance ? ammonia ? is used very widely at present. Ammonia is used as a coolant in various plants. I have compiled a list of all plants in South Bohemia that work with ammonia, including ice rinks. I characterized the properties of ammonia, what damage it causes to the human organism and the environment. I noted a list of accidents during which there have been ammonia leakages of ammonia and I analyzed one accident using a software programme called TerEx. I chose the building of the ice rink in České Budějovice for my research. The objective was to determine the amount of ammonia and to simulate, using the TerEx software programme, an accident with a potential ammonia leakage from the ice rink. I also listed all the activities of the individual components of the Integrated Rescue System, which would help during such an accident, as well as urgent and follow-up measures that would be used. Having assessed the results I came to the conclusion that ammonia leakage from the ice rink would have serious impacts on the residents of České Budějovice. Finally I explained what the terms of evacuation and individual protection mean for the people lining around the ice rink.

Leaks of dangerous chemical substances in the territory of the town Pilsen
KUČEROVÁ, Andrea
The topic of my thesis is: "Leaks of dangerous chemical substances in the territory of the town Pilsen". I have been dealing with this very hot issue, because there are more and more chemical substances around us. We can find a lot of companies producing, using and having these substances in stock, so we cannot rule out smaller or larger leaks. They usually have negative impacts on human health and life, animals, environment or the leak can cause high material damage. It is necessary to take new measures to decrease results of leak of dangerous chemical substances. In the theoretical part of my work I described some dangerous chemical substances, rules for behaviour and arrangments during the leaks of dangerous chemical substances. In the practical part I evaluated statistic records about leaks of dangerous chemical substances and I valuated talks with experts of public administration in the area of Pilsen town. I carried out my own modulation of ammonia leak in the programme ,,TerEx? and by that I gained an area of public danger where I performed an investigation among people. In my work there was verified a hypothesis whether the people living round the object with dangerous chemical substances have some knowledge about the individual protection. I came to conclusion that this hypothesi can be confirmated due to out comes of my questionary research ? our inhabitants are endowed with the needy useful knowledge (as I have been persuaded by). In my work I found out and important piece of knowledge that there had been only one leak of dangerous chemical substance some ammonia leak from the Pilsner ´´PRAZDROJ a.s.´´. It was an acceptional situation and it did not have any serious effect on people and environment. I would like to recommend only one thing ? to increase public awareness about possible danger in the place of domicile. It is necessary to say that people are only exceptionally interested in these safety questions. This work can be used within the public administration in the field of emergency management and accidental planning for (preparation of) inhabitants´ protection. It can also be used as some study material.

Ecological water service accidents in Tábor region during 1995 - 2005
URBAN, Jan
Ecological water service accidents in Tabor region during 1995 - 2005 In developed, densely populated area the requirements for water are increasing, as for the element that is necessary for life on Earth and for the production processes in human society. To ensure this needs covering became a limit factor of development of all economic spheres during the last years. That´s why the water management is getting into a front of public interest. The requirements naturally increase also in others economic spheres and all life fields. Filling of these requirements is connected with many actions, that influence the water purity. Beside the consequent water pollution or water quality inducement , we can talk also about the water-service accidents. Usually we speak about the emergent situations, that have the negative influence on a water useful qualities and cause biological, sanitary, visual and other defects. Redevelopment of these accidents are very laboured and expensive. That´s why the goal of all actions spheres is to precede the pollution of surface and underground waters in time. Subject of this work was the examination of water-service accidents in Tabor region in period of 1995 {--} 2005. The base of the examinated samples was a try to analyze the emergent situation causes, evaluation of solution mechanism of water-service accidents and evaluation of their incidences. By using the current knowledges the conclusions were deduced not only for the prevential sphere, but also for action-redevelopment and financial part of final stabilization. From the database 1995 {--}2005 were found, that on the Tábor region there were a 142 emergent accidents examinated {--} pollution, surface or undeground water threats, or technical problems in given region. Most of the problems were identified in agriculture and water-service fields (24% each), other accidents in food industry ( 13%), transport (16%) . Very serious emergent situations appeared on the pipeline, that goes throug the region. Among the unheathy substances the accidens were caused mainly by the oil products (in 52 cases),fertilizers and other substances used in agriculture caused the accidents in 41 cases. Mainly the human factor appears while accident rise {--} in half of examinated cases. From the results was also deducted, that in 18 cases the accidents appeared in water sources protective zone, 4 events happened in Protective zone of natural water accumulation Třeboňsko. 21 accidents caused the fish or other water animals kill. From the given balance-sheet and knowledges the following conclusions for prevential sphere were made: constructions, equipments or actions, that can influence the water situation are made with the agreement of water right authorities, Their contruction {--} technical implementation mostly doesn´t collide with valid regulations and standarts. In prevential sphere is necessary to keep the legal regulations, related mainly to the periodic checks and revisions of objects build for stocking and manipulation with unhealthy substances, also the prosecution of control systems and using the instruments usefull also for the water-service. Not only for the prevential sphere, but also for the check and redevelopment activities theirselves would be suitable to exert the simple analytic components. The negative part during the accident solution is the feedback and laboratory results absence. More workshops and work stations should have their own contra-accident instruments. Wrecking plans should be much more easier, current range should be include into a operating regulations. In the interest of fish and othe water animals protection the cooperation with specialised workplaces and veterinary authorities should be extended. Legal share of competence for the sphere of undergroung water little bit complicate the wrecking situations solution possibilities .

Consequences of deliberate chlorine leakage from Spolchemie plc, Usti nad Labem, and Spolana plc, Neratovice
KADLEC, Zdeněk
Most of the current population cannot imagine their contemporary lifestyle without chemical products. This requires the chemical industry, which in some areas of our country is well developed. Spolana and Spolchemie are large chemical companies, which store huge amounts of chlorine. The aim of this study was to evaluate the simulation of leakage of chlorine from Spolana and Spolchemie using TerEx software and see if the two businesses can be important sources of risk for the population in terms of leakage of chlorine. Results of this study imply much larger consequences that would be caused by potential leakage of chlorine through intentional misuse. This possibility should be of interest to not only integrated emergency services and members of crisis management teams, but also the citizens themselves. Preparing for such an event and knowledge of things in terms of prevention is very important.

Treating extraordinary situations connected with the leakage of dangerous harmful substances applied in the Brewery Eggenberg, a. s.
FUČÍK, Jaromír
The thesis treats the situation connected with the possible leakage of ammonia, applied in the Eggenberg a. s. brewery as cooling medium. It deals with the so-called worst variant of the accident {--} leakage of the maximum possible amount of the substance. The introduction is devoted to the legislation concerning the dangerous chemical substance, prevention of serious accidents, components of the integrated rescue system and the fire prevention. The thesis contains the characteristics and the description of ammonia as dangerous substance, with focus on its toxicity and it analyses the results of a possible leakage. For the simulation of a possible accident, the software instrument TerEx was applied. The calculations acquired after entering the input data into the program served for determination of the zone where the detrimental concentration of ammonia would reach in case of a leakage. In comparison with the original calculations performed in the last years applying the ROZEX programme, the zone with a harmful concentration would be substantially extended. The results of the thesis should be taken into consideration in the emergency plan of the region and in the emergency plan of the Eggenberg a. s., Brewery, however, also the procedure of the intervention of the integrated rescue system components shall be specified. Moreover the way of performing the inspections in the section of the fire protection in subjects applying, processing or storing dangerous chemical substances and preparations is drafted. The thesis tries to draw the attention to the fact that also a relatively small amount of a dangerous chemical substance may cause a considerably significant accident.

Protection of populatin in the immediate environment of icestadiums.
HAVLIS, Václav
Ice rinks have become important sport facilities in towns and cities. They are mostly situated in densely populated centres. The ice is made and kept by refrigeration plant placed in the stadium engine room. Refrigerating medium is mostly ammonia which is toxic, irrritating and harmful to the environment. Considering this fact, eventual breakdown of the refrigerating system poses a risk for people in the surroundings. The work is particularly aimed at preparing an instruction manual for integrated emmergency system and state authorities to upgrade their theoretical and practical knowledge and to be used as a supportive material when dealing with refrigerating system breakdown and consequent ammonia release. A technique used in the Bachelor´s work was a model breakdown demonstration of the ice rink in Jindřichův Hradec. Then all the data obtained were evaluated by the TerEx programme and finally relevant steps and measures were suggested. The findings revealed the fact that the attention is mostly paid to response recommendations in the breakdown centre while the surroundings are not involved sufficiently. The manual application together with upgrading material equipment may significantly reduce the negative effect of the breakdown on the ice rink surroundings and, especially, on civilians.

Measures to ensure population protection in the emergency planning zone Tomegas Ltd. storage of propane - butane Branice
FOŠUM, Daniel
The aim of this thesis is to propose measures to implement the emergency planning and emergency clearance operations, to prevent or reduce the immediate risk of accidents, according to documents provided by the IRS components, the community, administrative bodies and the storage operator. Another objective is to propose measures ensuring protection of the population in the emergency planning zone, in order to satisfy in the best possible way the following hypothesis: "Measures to implement the emergency planning and emergency clearance operations and measures to ensure population protection are an integral part of the external emergency plan, ready to resolve possible accident cases endangering lives, health, significant property values or the environment." To meet the objectives and verify the hypothesis, I used my own experience in the field of emergency planning and my personal knowledge of the site so that I could create a proposal of appropriate measures, designed to reduce an immediate menace, and mitigate the impacts of a possible major accident. To complete the goal I chose ``The storage of propane - butane bottles and bottling plant Branice at Milevsko", the local juristic person with the name TOMEGAS Ltd. By the South Bohemian regional authority, these operations were classified as category B under Act No. 59/2006 Coll., on the prevention of major accidents caused by selected hazardous substances or chemical preparations, and also an emergency planning zone with a radius of 1 km was established. Those objectives are proposed in accordance with all legal standards and regulations. I believe that the findings of my work will be applicable in building and updating an external emergency plan for given operations. The hypothesis is undoubtedly confirmed by the existence of international treaties and the EU legislation focused on the protection of people living in the neighborhood of buildings where dangerous substances and preparations are handled, as well as by the number of accidents happening worldwide. In the section ``Discussion{\crqq} several issues are analyzed, the major of which seems to be the financial aspect that may result in difficulties with the early establishment of proposed preventive measures.

Action of the integrated rescue system´s unit and activity of the crisis crew of the Trebon city with extended competency by the accident of the tank transported hydrofluoric acid.
ŘIMNÁČ, Jiří
Road transport of dangerous substances represents a risk of emergency situations in which the transported substances can get out of control. The transport of dangerous chemicals has always been actual problem. It has been regulated by international directives, which determine the rules for handling of dangerous chemicals. Emergency situations related to a cleanup of dangerous chemical spill require an action of the Integrated Emergency System. This joint action is regulated by legislation and special regulations. This thesis is aimed to the legislation concerning the transport of chemical substances. It provides information on the vehicle designation used for transport of dangerous chemicals, and the identification and features of these compounds. The thesis also characterizes current situation in the district of the town Třeboň. It also describes the Integrated Emergency System, its structure and activities in case of emergency event caused by dangerous chemicals. As an example, the thesis explains procedures for individual bodies of the Integrated Emergency System during the joint action after an accident of the vehicle transporting hydrofluoric acid.
