Abstract

The thesis presents the technological structure of natural gas filling stations and explain the function of the major elements as the compressor, tank, gas drying unit a dispensing equipment. Then it describe some physical and chemical properties of the compressed fuel, which is characterized as highly flammable and explosive substance. Followed by a list of some risks of technology devices which try to explain the hazards of filling stations, notably is possible of misuse with the external perpetrator. This observation is verified by evaluating of the document, which applies to the safety of public filling stations for natural gas. This document does not deal with the technical security against sabotage. In own part of the thesis the author describe to a fictitious filling station, which thanks of the location and the disposition could be there a possibility of terrorist attack. There are also analyzed the security risks of a possible penetration to the reservoir of compressed media. On the base of this options are presented the technical security against sabotage acts, which are divided according by the areas of protected filling station on the mechanical and electrical security systems. At the end of this thesis is recommend the possibility of extending closed circuit television which are installed on the fictitious filling station.
