In recent years in the process industries much attention has been paid to the quantitative risk analysis (QRA). This study describes a QRA evaluating the risk from the operation of an LPG installation. Both individual and societal risks to the installation personnel, customers, and neighbors/passerbys are evaluated. The study showed that the largest effect is caused by a jet fire and flash fires. Unacceptable individual risk is being imposed on personnel, consumers, and third parties. Societal risks are also unacceptable in comparison with the Installation's acceptable risk criteria. Risk reductive measures proposed for the Installation include the application of smaller pipes and fewer flanges in Compressor room, the use of smaller vessels in Storage units and the use of Emergency shutdown valve.
