Detection and Laboratory Assessment of Releases of Hazardous Chemical Substances into the Environment Requiring Fire Brigade Chemical Lab Call-out
Holánová, Iveta ; Hradil, Jaroslav (referee) ; Mika, Otakar Jiří (advisor)
The diploma thesis is focused on a detection and a laboratory control of hazardous substances’ leak into the environment. These hazardous substances are classified. Further, it aims to chemical laboratories of the fire-brigade of the Czech Republic, as well as which place they hold in the fire-brigade system, and it indicates their main duties. This diploma thesis contains a review of some essential types of devices and mediums, which are in terms of the fire-brigade of the Czech Republic usable to practice the detection, determination and assessment of the hazardous substances in various figures of the environment in terrain, i.e. filling of duties of the chemical survey. The output of this diploma thesis is simulation of leaks of the toluene diisocyanate using ALOHA software, TerEx software and Rozex Alarm software. Further on, the proposal of another methodical sheet focused on leak actions of the concrete hazardous industrial substance – toluene diisocyanate. This methodical sheet could therefore broaden pro tempore elaborated sheets for chlorine and ammonia.

Plan of Measures for Implementation in the Event of an Emergency Situation in a Research Institute Building
Mlejnková, Petra ; Svoboda,, Bohuslav (referee) ; Hradil, Jaroslav (advisor)
This work deals with the elaboration of an action plan in the case of emergency (e.g., fire, explosion, leakage of hazardous chemicals, etc.) in the manufacturing Company VUES Brno. The Action plan, which is designed on the initiative of the Department of Civil Defence - District Brno – north, will become a part of the response plan within this district. The thesis applies particular requisites of the emergency plan in terms of the district Brno - north. The main requisites include the warning responsible authorities, the residents informing, the guidelines for sheltering and evacuation of residents, and the organization of a medical support. The action plan (Particulars requisites) is accompanied by corresponding legislation. The danger zone was determined by the model release of hazardous substances used in threatening object using software ALOHA and TerEx. These programs evaluate the possible consequences of the accident according to physical and chemical properties of the substances based on the conservative projections. Results correspond to the worst possible consequences of the situation. In the case of manufacturing Company VUES Brno the highest risk was evaluated as a fire of flammable liquids. The danger zone was set at 100m in the surroundings. Particular steps for population protection are therefore planned for the distance 100 m from the object. The work also contains the graphical part of the map marked with the radius threat map of evacuation routes and map roadblocks. In order to improve the awareness of potential emergency for the population living nearby, a leaflet containing necessary information in the case of emergency was designed.

Population Protection against Impacts from Major Chemical Accidents
Popelová, Barbora ; Hradil, Jaroslav (referee) ; Mika, Otakar Jiří (advisor)
Population Protection againts Impacts from Major Chemical Accident in recent years is an important area to address. This thesis focuses on the current situation and preventive security measures in protecting the population against the effects of serious chemical accidents. Specifically, it focuses on the Czech Republic and toxic industrial chemicals, explosive and flammable. A detailed analysis of the current situation in the Czech Republic with risk areas relating to chemical industry and hazardous chemicals was worked out. An analysis of the current status of population protection from the effects of serious chemical accidents is prepared. On the basis of the analysis measures are suggested to improve the current situation in accordance with legislation. The work was carried out research on their own knowledge of the population in this in pre-selected location.

Basic Aspects of Population Protection against Consequences of Chemical Terrorism in the Czech Republic
Drápal, Stanislav ; Hradil, Jaroslav (referee) ; Mika, Otakar Jiří (advisor)
The theme of my bachelor work is The basic aspect of population protection against conseqences of chemical terrorism in the Czech Republic. In my bachelor work, I drew from home and foreign sources over the past ten years. The opening part of my work deals of basic concepts relating to terrorism and its branches. It states some case studies of terrorist attacks against civil inhabitants with the aid of chemical agents. The middle part engages in a characteristic and dividing of particular chemical warfare agents and dangerous toxic chemical agents. There are stated lawful norms and measures used in the Czech Republic. Also processes of medical sectors Emergency Rescue System in provision of pre-hospital urgent care in cases of mass impairment of health. In closing I analyse preparedness of inhabitants in the Czech Republic to possibility of a chemical terrorist attack and I suggest a handbook „The danger of a chemical attack“ to civil inhabitants.

Protection of Population against Consequences of the Chemical Accidents
Veverková, Ivana ; Hradil, Jaroslav (referee) ; Mika, Otakar Jiří (advisor)
This thesis aims to protect populations in chemical accidents. The introductory chapters present basic concepts related issues, basic terms on hazardous chemicals and their markings. You can also find here case studies of chemical accidents from the past compared to he present. It is important to note the consequences of accidents that can affect all sorts of situations. Regarding the issue of protection of the population, there is an overview of suitable means to prevent these dangerous substances, which continues to guide how to behave in case of an accident. This guide should be beneficial to anyone who is in the emergency planning zone and is therefore more vulnerable. At the end of this thesis we can find the state of readiness assessment and proposals to improve the situation.
