The risk of serious accident is increasing with the rise of the amount of chemical industry manufacturing. This accident can have immeasurable consequences. The aim of this thesis is to point out the consequences caused by leakage of dangerous substance of petrol from the biggest cistern in chemical company Synthos Kralupy a.s. and to suggest steps for emergency clearance. To fulfil the aim, examination of serious accident risks had to be carried out first. The method of Dow's Fire and Explosion Index was used for this examination which enabled evaluation of a real fire and explosion risk. Apart from these methods, another method called IAEA-TECDOC-727 was also used. Consequently, possible scenarios of dangerous substances leakage from storage cistern were created. These were simulated through software programmes ALOHA and TerEx. Acquired results were then well arranged in charts. During the research of this issue, a method of controlled interviews was used. These interviews with employees of firefighter emergency service were focused on emergency readiness of the chemical company Synthos Kralupy a.s. A cistern containing dangerous substance represents a crucial risk, even though the results showed that the accident of all petrol leakage from the cistern is very unlikely. However, this accident should not be neglected because a dangerous cloud reaching 565 m from the site of the accident would occurred. The dangerous cloud cause mortality of 70% within a distance of 2,000 m and a distance of 4,970 m to the 1 st degree burns. If all petrol leaked from the cistern, the consequences would be much bigger than just pollution. It would also include death toll, health problems and vast property damages. |
