Risk Assessment of Ilam Gas Refinery Based on William Fine Method in 2012

Introduction: Industrial growth, development programs and infrastructure projects, in spite of numerous advantages and benefits, have been considered as the source of many hazards, risks and failures. Risk assessment is the organized and systematic methods to identify hazards and risk estimation of decisions ranking, in order to reduce the risk to an acceptable extent. The aim of this study was the risk assessment of Ilam gas refinery using William fine procedure. Materials and Methods: Executive group, including managers of the gas refinery departments and agencies, was formed in order to identify the risks. The risks of units using the form HSE-FO-001 (0) -90 were identified and the risk assessment was recorded. This technique is based on the calculation and assessment of risks with a severity of the outcome, occurrence probability and exposure. Results: 289 risks were found in this study, of which 5 risks (1.73%) had a level of urgency (urgent need for corrective actions), 40 (13.84%) had abnormal levels (need of immediate attention) and 244 (84.43%) had a normal risk level (should be deleted). Conclusion: According to information obtained from the risk assessment tables, the major risks that threaten employees of Ilam gas refinery including the risks associated with working at height, inhalation of gas containing H2S and exposure to excessive noise. Therefore, engineering measures must be conducted to reduce the level of risk in the refinery units.
