The final work describes the application of preventive fire protection measures used to protect storage tanks in the petroleum industry and firefighting tactics in the case of fire. Oil is one of the most important energy resources and consequently, there is a big demand for it. Therefore, many oil depots were built for the storage and further transport of oil and oil products. This final work generally deals with fire and fire extinguishing, with special reference to the combustion of flammable liquids and extinguishing agents. It also discusses the significant role of stable fire protection systems, especially drencher systems which are used in oil terminals. Further on, it describes the type of storage tanks used for oil and petroleum products storage, as well as various versions of the fire protection stable systems. The accident analysis and statistics of the accidents that have occurred in the past have identified imperfections and failures which can be helpful in the future. As an example of oil derivatives depot, this final paper describes reception and forwarding terminal of Janaf Žitnjak.
