Statistic Review of Parameters of Fire Rescue Service's Interventions in Traffic Accidents in South Bohemia
PETRŮV, Josef
Fire Rescue Service is territorialized in each region, which means that Fire Rescue Service is present in each region of the Czech Republic as an individual accounting entity. Each accounting entity is obliged to prepare own budget estimate for next year which serves for covering costs related to interventions. Therefore it is beneficial to have an overview about the number of interventions expected in following year. The prediction of the expected interventions should be based utmost on real data from the the last period. Fire Rescue Service units' interventions in traffic accidents are covered from the state budget as well as other performances. The thesis is concerning the statistic survey related to Fire Rescue Service's interventions in traffic accidents. Specified goals of the thesis: G1) The survey of the development in time of the number of traffic accidents associated with South Bohemia Fire Rescue Service's interventions in traffic accidents within one month as the unit of time during the last 5 years. It is considered as the survey of the first of selected parameters concerning Fire Rescue Service's interventions in traffic accidents in the South Bohemia region. G2) The survey of the development in time of costs associated with South Bohemia Fire Rescue Service's interventions in traffic accidents within one month as the unit of time during the last 5 years. It is considered as the survey of the second of selected parameters related to Fire Rescue Service's interventions in traffic accidents in the South Bohemia region. G3) The comparison of the number of interventions and costs, the investigation of the apportionment of the number of interventions and costs in terms of a proper theoretical apportionment. It is considered as the survey concerning the dependence of selected parameters of Fire Rescue Service's interventions in traffic accidents in the South Bohemia region. With regard to a relativelly high number of primary data (entries from about 8 000 traffic accidents in the time period between 7/2010 and 6/2015 in the South Bohemia region, where was always present at least one unit of the South Bohemia Fire Rescue Service), mathematical statistic tools were needed to create a survey of selected parameters of the data file. Determining intervals for individual statistic features is to some extent carried out "by feeling". With regard to it, there was done the sensitivity analysis within which was investigated the influence of minor changes in the number of intervals on apportionment of percent occurrences of monitored statistical features (intervals were determined "by feeling" and based on recommendation from technical literature). For investigation of statistical features were used description statistics and also methods of statistical induction. The information used from technical literature and the interpretation of partial results and conclusions concerning individual sections of the thesis are provided in the section Discussion. The thesis demonstrated that the empirical apportionment of the number of traffic accidents and costs on South Bohemia Fire Rescue Service's interventions in traffic accidents can be considered as standard. Therefore it is correct to use theoretical findings associated with standard apportionment to work with those data. Also the thesis demonstrated that the number of traffic accidents and costs associated with South Bohemia Fire Rescue Service's interventions not only does not decrease but on the contrary increases. It was demonstrated that there is present very high positive correlation between numbers of the traffic accidents and the costs related to South Bohemia Fire Rescue Service's interventions in single months of the monitored time period. This brings us to a conclusion that the increase of costs related to interventions is caused mainly by the increase of the number of traffic accidents where the units of Fire Rescue Service intervene.

A comparison of the radiometers which are used by the Fire Rescue Service of the Czech Republic
PETRŮV, Josef
Fire Rescue Service is the basic component of an integrated rescue system, with high working demands placed on their activity. The number of activities firefighter units perform is extensive; especially great attention is paid to interventions with eventual incidence of ionizing radiation. Ionizing radiation is not possible to detect by human senses, but is possible to detect with special instruments. Identification of ionizing radiation is not simple; it requires certain amount of time, professional knowledge, and facilities. To prevent irradiation of people who are present at an intervention place and also people who intervene, the units of Fire Rescue Service of the Czech Republic are equipped with the portable ionizing radiation detectors according to Conception of Chemical Service. These are namely DC-3E-98, DC-3H-08 and Ultra- Radiac (U-RAD 115). The instruments are constructed to detect radiation. The goal of the thesis is to compare instruments in terms of the accuracy and speed of measurement and to assess suitability of use of the instruments by fire protection units of the Czech Republic, economic comparison and the practicability of the instruments. DC-3E-98 is hand contamination detector used for surface contamination and dose rate meter that dates with its design back to 1970s of the series DC-3 used for operative radiological survey. It was developed and manufactured in today's nonexistent plant Zavod mechanizace a automatizace Ostrov nad Ohri. This device has been used until recent days after had been modified at the end of 1990s and because of needs to follow Act on Metrology. It is consisting of two parts, separate instrument and removable probe. Both parts create easily demountable unit allowing carrying out measuring by only one hand. Its great advantage is fast response and large-area probe with Geiger-Müller tube used as a detector. DC-3H-08 is the latest type coming out of type series DC-3 and was developed by the innovation of previous type DC-3E-98. This device was developed by the company VF a.s. Cerna Hora using financial sources coming from European Union for the Fire Rescue Service of the Czech Republic. It is the instrument with satisfactorily large display and robust construction suitable for measuring outdoors. It is consisting of two independent parts - indicator and basic units. When mounted together, the device works as complex, when separated, each unit can work independently and the communication between them is wireless using Bluetooth. The device is possible operate using four buttons at the indicator unit. It is possible to use the device for measuring kerma dose in the air, areal dose equivalent dosage, surface activity, accumulated dose and for checking people's contamination. The disadvantage of the device is its heavy weight and impossibility of controlling audio output, operating time (only 4 hours), and its high purchase price when compared to others. Ultra-Radiac (U-RAD115) is hand detector determined for indication of gama radiation sources, measuring dose rates, scheduling the time for people who intervene, setting-out safety zone for gama radiation and for direct data reading of accumulated dose. The device is company Canbera Dover Inc.' product. It is device of smaller size; its operation is actually easy and intuitive with the help of six buttons. It is suitable to be used outdoors because of its robustness. This device is recently sufficient for basic units HZS CR and when Canberra Packard finishes prototype stage of beta probe of this device for our market, it can fully replace device DC-3E that is recently serving out.
