Quantitative Risk Assessment in Process Plant

Abstract

This paper outlines quantitative assessment of a critical event in the sub-section of a process plant where in a key ingredient required for the manufacture of propellants is produced. This sub-section is identified as possessing a fire hazard by qualitative HAZAN techniques. Fault tree and safety. tree analyses have been used to identify basic equipment and the operational failures which could lead to top event occurrence and to calculate its probability. Consequence analysis of one of the probable scenarios has lead to an estimation of risk in terms of fatality and injury . These results form basic inputs for risk management decisions.
