Steam Boiler Hazard Identification Using Analytical Network Process (Case Study: Farabi Hospital)

Steam boiler is a common primary utility that creates steam by applying heat energy to water in a close system and poses different threats. The present study aimed to identify health, safety, and environmental hazards by implementing Hazard Identification (HAZID) method and Analytical Network Process (ANP). Therefore, the identified hazards were categorized and scored by HAZID method and then, prioritized using ANP. A total number of 58 hazards were identified in 4 categories; of which, 6 hazards were weighted by the super decisions software. According to the results, job stress and cooling system wastewater were recognized as the most and the least important hazards, respectively.
