The aim of the diploma thesis is to assess contamination by chemical substances of selected operating premises at the FRS stations of the Pardubice Region. Elevated contamination by dangerous dangerous chemical substances of the mentioned premises can be results of many factors, from technical to organisational ones, and as a final consequence of this, it may influence firefighters´ health negatively. The theoretical part of the thesis presents basic information about the organisation, duties and securing the operability of chemical and technical services material equipment. Furthermore, knowledge of possible risks of contamination of material equipment and about inspections of the chemicals in operating environment are presented. In the survey part, air contamination of 13 selected areas is assessed during everyday operations and once in an intentionally contaminated area. As the measuring procedure in all the selected areas, air sampling through adsorption tube with Tenax sorbent was used. Specifying the chemical substances in the samples is implemented by the means of a thermodesorption equipment and a gas chromatograph with a mass spectrometer. Furthermore, sampling in sample bags with following analysis by the means of infrared spectroscopy is implemented in contaminated areas. There are 42 air sampling in Tenax adsorption tubes and 2 air sampling in sample bags implemented altogether. Numbers of volatile organic substances is identified in the surveyed areas, most of them benzene and toluene. From identified inorganic gases hydrogen sulfide is discovered in one case, which concentration exceeded strongly the hygienic standards set by the Czech legislation. The identified results not only can influence securing the operability of material equipment but also contribute to a general reduction of firefighters´ exposure to dangerous chemical substances.
