[automatically translated] Storage tanks of petrochemical plants are a serious threat to the preservation of the environment, because of the disastrous consequences resulting from their collapse, as highlighted by the recent catastrophic events. Therefore, ENEA and GLIS have undertaken intensive research and information to raise awareness on these important dangers. Among the most frequent causes of collapse are cited seismic actions are particularly relevant in areas close to active faults, as is that of Priolo Gargallo, in the province of Siracusa, once the seat of destructive earthquakes. Damage is often magnified by Fires following the earthquakes. Therefore, in recent years they have made numerous interventions aimed at increasing the safety of these facilities from the seismic actions. Among these seismic isolation it is one of the most effective techniques to ensure adequate safety margins. This note refers on procedures performed in Priolo Gargallo (SR), where they have been adopted isolation Devices of the friction pendulum, it can also withstand heat that could develop in the event of fires, some notions on the premise ' seismic isolation and in particular the operation of the friction pendulum.
