Introduction: One of the requirements of the environmental risk assessment of hot rolling industry is the evaluation of the performance of equipment and devices in the industry and identifying subsequent environmental risks.

Methods: This was a quasi-experimental study. After classification of the equipments in the production hall of hot rolling at the Kavir Steel Complex, some operations were conducted to identify the environmental risks according to the ISO 14001 approaches (such as pollutant emissions to air and water, energy consumption, equipment depreciation, etc.), using "What happens If?" technique. Then, a team of experts conducted the initial risk assessment using William Fine method; they also proposed the corrective strategies and calculated RAC₂. Data were analyzed using SPSS version 19.

Results: 280 environmental risks related to the proper functioning and defective equipment were identified, which the largest number of risks was related to the production machinery (29.2%), and mechanical equipment (24.2%), respectively. The most category of identified environmental risk (21%) was related to the creation and distribution of waste and the risk of pollutant emissions into the air (18.5%), and the lowest percent (2.5%) was related to the risk of corrosion and depreciation of equipment.

Conclusion: The establishment of environmental management in rolling industry will play an important role in controlling emissions arising from the industry to the environment, if it relys on the continuous equipment monitoring in the framework of the maintenance and repairing plan in order to prevent technical defects affecting the environment.
