Abstract
The main object of this paper is to evaluate safety barriers intervening against overpressure
implemented on a crude oil heater using layers of protection analysis approach suggested in IEC 61508
(International Electrotechnical Commission) Standard for the determination of safety requirements are
illustrated. Accident scenarios are pre-identified using Hazard an Operability approach, Fault tree approach is
required for an effective risk assessment process. In order to better appreciate accident scenarios, P
(Process Hazard Analysis Software Tool) is utilized to simulate them.
