  An extensive hazard identification of petroleum industries as part of a sound safety analysis is not only highly recommendable but often subject to official approval of construction by the national governmental authorities. Risk assessment and management techniques are used in industrial activities to diminish accident potential by the application of prevention or protection techniques to improve process safety. This project aims at introducing a preventive approach to process hazard identification and identifying, evaluating and control of Health, Safety and Environmental hazards in studied unit. For this purpose, Hazard and Operability Study (HAZOP) have been applied to an oil storage and process unit in Hamadan. The HAZOP is the most widely used of the various analysis techniques available, in part because this highly structured technique is easy to teach and well-suited for petroleum industry. 1180 hazards identified by completing the study. The results of research showed that 38.136% of identified hazard were unacceptable. The root cause of 31.35% was unsafe behaviors. Considering to catastrophic consequences of probabilistic accidents, the results emphasize on control of unacceptable hazards and recommends installing pressure switch and flow switch on the product receiving lines and conducting of regular and periodic HSE auditing plans.

  Considering safety measures in industrial and chemical facilities is a fundamental issue. Statistical figures and facts display the great impact of industrial accidents on humans’ life as well as economic and environmental damages. Industrial accidents are amounted to high percentages of accidents around the globe. In addition, some of these damages are irreversible. Therefore, discovering and preventing these damages and assessment of the risks which lead to these damages, requires specific strategies and guidelines in addition to risk analysis in industrial units. In this research paper, risk assessment and risk analysis of utility unit of Fifth Gas Refinery of South Pars Gas Complex has been studies. HAZOP Technique has been used for risk assessment of this Unit, which has been established to detect the procedural problems, so, the existing deviation has been assessed by HAZOP team. The result of the study showed the use of experts’ recommendations from HAZOP method for risk management and increasing safety and procedural measurements of the Unit. Based on compiled expertise, utility unit efficiency depends strongly on flow and compression for this unit, since the inflow stores in reservoirs initially and distributed in this unit with a proper pressure. Therefore, it is vital to regulate these parameters as far as possible and prevent their inadequate increase and decrease. The flow circulates in system with a normal procedural pressure rate and can prevent the probable damages such as lines break down due to high sensitivity against high tension and stopping pump and unit being out of service due to decrease of flow. the most important recommendations in this study include: installation of temperature and pressure alarms in unit. Therefore, based on the obtained results from this study, unit setup guidelines and policies have been reformed. Manuscript profile
