Combustion of fossil fuels is one of three ways to  produce electric power (steam; electrochemical; hydroelectric).  Several environmental exposures, as hazardous waste, air  pollution, flammable and combustible fluids are related to power  facilities. Fuel storage areas are particularly vulnerable sub-systems of power and industrial plants determining  relevant  industrial risk. Recent catastrophic seismic events occurred in last  years increased attention about risk related to seismic hazard.  Due to recent Italian rules (follow up of European Community  guidelines) oil storage systems have been classified as risk or  relevant risk facilities. National industrial risk classification data  analysis pointed out that many exposures are located in seismic  areas that are, in addition, very populated. In the present paper  some issues related to probabilistic approach to vulnerability  assessment of atmospheric steel tank for oil storage are discussed.  Procedures for risk assessment starting from concise  vulnerability formulation and seismic hazard quantitative  parameters are analyzed. Review of experimental and field data  is reported and research needs are finally summarised.
