Abstract :
Risk assessment and management techniques are used in industrial activities to reduce accidents by
applying preventive and protective methods. In this article a preventive approach called Hazard and
Operability Study (HAZOP) was used. The application of HAZOP, a process hazard identification and
control method, has been demonstrated in the fatty acid unit of Golnar Oil Company, northwest of Tehran
Province. The results of the study identifies 58 types of hazard of which 45.6% were unacceptable, 27.1%
were unsafe, 18.6% were acceptable but needed reconsideration, 8.7% were acceptable with no need for
any corrective action. To prevent any catastrophic consequences, we recommend: (1) installing pressure
switch and flow switch on the product-receiving lines, and (2) conducting regular and periodic HSE audit.
