کاربرد روشهای WilliamFine , PHA در مدیریت ریسک مخاطرات زیست محیطی و برآورد هزینه های کنترلی در مجتمع فولاد کویر

Abstract Introduction: In the absence of proper control, environmental hazards and risks from industries, can be irreparable damages to the environment. Hence, this study with the aim of environmental risks identification and assessment (such as emissions to air, discharges of pollutants into water, the discharge of pollutants in soil, consumption energy, etc) and estimation of control costs by (william fine) and (PHA) method in the Kavir steel Complex. Methods: environmental hazards that identified by field observations, categoried on the Preliminary Hazard List (PHL) on unit, human activities and performance of the machines in the production hall of Kavir Steel; then was done  risk assessment by William Fine method for calculation of (RAC1). After providing reform strategy for critical risks , (RAC2) calculated. In this study was used software (SPSS) version 19 for statistical calculations. Results: According to this study, the number of 356 environmental risk, in the form of 9-risk groups, identified. before the offered intervention strategies, the number of acceptable risks 89, the lowest practictable (ALARP) 204 and 63 was unacceptable risks. prospecting after the offered intervention strategies, changed the number of acceptable risks 183 and the lowest practicable (ALARP) 173. Conclusion: The results show that the comprehensive identification and assessment of environmental risks in the rolling steel industry, presenting technical flaws and imperfections and errors of destructive environmental staff to the issue of environmental and making necessary to auditing environmental, and changing attitude of personnel, sensitivization of rolling steel industry personnel to maintain and improve the health of the environment.
