Risk analysis for installations containing large amounts of flammable substances is important to ensure safety and to meet legal requirements. This article deals with a QRA (quantitative risk assessment) of a typical LPG (liquefied petroleum gas) storage installation that is common in many refineries. An incident in the isobutene tank may cause a 'domino effect' due to its location. QRA allows one to identify and rank incidents that contribute to total risk. A methodology based on the risk concept that considers the dependence between hazard potential and associated safeguards is an effective way to assess plant safety. The proposed methodology allows a calculation of individual and social risk curves.
