All nuclear power plants in Slovakia can effectively prevent emergencies caused by technical or human error. Before commissioning, they must demonstrate to the Nuclear Supervisory Authority that the plant can respond to even extremely unlikely events. The design of the plant has safety systems that will prevent damage to nuclear fuel and the release of radioactive substances so as not to endanger human health and the environment. The maximum design accident for a WWER-440 reactor is a rupture of the main circulati...

Radioactive radiation is the common part of our lives due to natural sources producing the radioactive radiation. The radiation coming from the nuclear power plants is very law comparing to natural or common sources unless some accident happens. The paper deals with two well-known major nuclear power plant incidents and one local silent accident which took place in Czechoslovakia. Three Miles Island as an accident with no direct fatalities is introduced from the medical consequences point of view. Some longterm re...

The paper deals with the causes of numerous local floods and flash floods in forest areas and neighbouring location. Forest wood mining forest roads and approach paths are proven to be the main cause of forest drainage and loss of its accumulation function. Forest roads intended for logging cause drainage of large areas, easy runoff of rainwater as well as subsequent drying of the soil, weakening of trees and devastation of the forest. Two successful projects for the recultivating of forest roads have been present...

Flash flood is a very dangerous type of flood that can happen with little or no warning. The flash floods becoming more frequent in the territory of the Slovak Republic, typically for last decades in Central Europe. The number of responses of regional Fire & Rescue Corps connected to the flash floods is very high nowadays. Extreme weather fluctuations due to climate change are threatening drinking water sources as well as new types of natural threats. Severe storms and tornadoes are expected to occur more frequent...

The paper deals with the possibility of software tools to control the environmental crime. The original software tool was developed to control the criminality on social networks. The main idea is to focus on the criminality related to the environmental crime. The paper describes the system of the software control, its application and usability. Also other known software tools are mentioned in order to compare the advantages and disadvantages of their use. The previous approaches to create the software tools able t...

The paper deals with quantitative methods of risk management applied to a crisis event of criminal origin. Two quantitative risk assessment methods are introduced. The event tree analysis and the RM/RA CRAMM method are applied from the perspective of crisis management in the phase of criminal crisis prevention. The advantages and disadvantages of the quantitative methods compared to qualitative methods are discussed. The quality of input data is accented to get reliable results that can be seriously taken into acc...

Reduced air supply, significant temperature rise, dense smoke, are the characteristic factors of fires taking place in the interior of buildings. The interior fires often cause dangerous phenomena such as flashover and rollover, and in some cases massive explosions of accumulated emissions of combustion called backdraft. These phenomena and the course of fire temperatures in the areas are the subject of many studies in order to understand them as well as possible. The main goal of the paper is therefore to enrich ...

The paper deals with the actual flood risk assessment in Slovak Republic. The recent history of massive floods within the territory of Slovak Republic and their character is described as well as the latest flood and changing character of the flood causes. It is usually a natural disaster that occurs due to sudden or unexpected changes in the meteorological situation. A brief description of the crisis management bodies with focus on the major responsibilities of the Fire & Rescue Corps within the current Act on Flo...

The paper deals with the quantitative risk assessment approach to the use of the universal quantitative method RM/RA CRAMM. The method is applied to criminality cases related to arson and other cases of environmental insensitivity influenced by social background. The arson statistics recorded in Slovakia are usually hidden behind other reasons of the fire cause. The hypothesis is that there is a certain impact of the social environment on criminality, including arson behaviour. The quantitative method needs quanti...

The aim of the work is to point up on the relation among Arson criminality and social network groups. The impact of the internet social networks on arson crime is discussed in the paper. The impact of the top social networks incl. facebook or twitter is generally very high on the society. The arson criminality is partly hidden in the fire statistics especially in Slovak republic were the fire cases investigated with unknown fire source usually point up on the unknown perpetrator. Fire related crimes are often disc...

The risk analysis as a part of risk assessment by RM/RA CRAMM method is a critical step in order to calculate final risk values for all the subjects assessed. Step-by-step risk analysis includes major natural and industrial hazards such as flood, land-slide, forest fire and chemical leakage. Both, the air-pollution and respiration ways irritation are part of the risk assessed. The risk assessment scoreboards are used repeatedly for each type of hazard source. The method takes into account a previous risk identific...

The chemical hazard for Pezinok District is analysed. Risk identification of the objects with high amounts of chemicals includes both industrial and the common civil objects and facilities. The highest possible number of people under the risk in case of chemical leakage as a result of terrorist attack is taken into account as well as the health consequences according the certain concentration of the chemical matter. The air pollution period and environmental impact on the fauna and flora, including soil contaminat...

RM/RA CRAMM method is a multispectral method for risk management including risk assessment process. It is used mainly for environmental, technology and social threats including major natural emergency events e.g. floods, forest fires, whirlwinds, earthquakes, landslides etc. The paper explains the logic of the method and its application though the Risk Assessment Scoreboard with quantitative inputs and outputs calculated by a simple logic function.

The combination of wood-PVC was used for the first time at an outdoor fire test on a reduced scale. From a scientific point of view, there is a strong the need to repeat similar fire test with a combination of materials that occur in the interior of buildings. It opens the opportunity to confront theory with the results of similar tests carried out. The combination of traditional and modern materials in interiors of buildings occur very often. Both wooden and or wood-plastic composite materials are mainly used to ...

Leaking oil, diesel, gasoline and other dangerous substances transported in large amount mostly on roads and railways affect the soil, rivers and underground fresh water. The fast reaction is necessary in order to stop leaking and to protect the surrounding environment. There are usually no special sorbents at the place of accident, therefore improvised sorbent should be used. Some of natural sorbents are surprisingly effective. Improvised sorbents were experimentally deeply tested in order to find out their chemi...
