Assessment and Management of Health and Safety Risks in the Transportation of Hazardous Materials Using TRRI and Modeling with PHAST and Pathfinder in Tehran (Case Study: Gasoline Transportation)

Abstract

Background and Objective: The transportation of dangerous materials can lead to catastrophic accidents in metropolises. Assessment of the risk of transporting such materials and determination of the consequences can prevent possible accidents and consequences. Materials and Methods: In this regard, the TRRI method was used to estimate the quantitative risk index. Assessment and analysis of determinantal damages resulting from accidents of sudden discharge of such hazardous materials were performed by PHAST software. Furthermore, Pathfinder software was used to simulate individual reactions, and manage conditions and their distance from the accident zone. Results: Assessing the risk of transportation of jet fuel was estimated to be 144 using the TRRI method. Analysis of the consequences indicated that the sudden discharge of fuel in the first six months of the year, the consequence of the explosion of a jet fuel tanker up to a radius of 120 meters cause irreparable damage to the surrounding buildings. The findings of this simulation showed that the pool fire scenario of the people who are exposed to 12.5 kW/m2 radiation in the first and second half of the year in the sudden discharge scenario prevents the person from first or second-degree burns. Conclusion: Considering the significant road transport of hazardous materials and the high severity of the consequences of possible accidents in the intracity transportation of jet fuel, designing a time of safe transportation of materials along with determining safer routes can reduce the risk of such incidents.
