Quantitative fire and explosion risk assessment of fuel tanker truck: Preliminary case study at fuel terminal x jakarta

Abstract

The distributions of fuel using tanker truck have been increasing in terms of complex risks related to the potential of fire and explosion. Various studies and case reports have proven that the level of accidents or fire and explosions of fuel tanker trucks is rising. The objective of this study is to calculate personal and societal risk levels. Preliminary case study was conducted in filling shed of the Fuel Terminal X Jakarta. Data on locations, materials, meteorology hazard identification, activities and process, case reports, and installation were collected from measurements, observations, or interviews processes, as well as provided by the company and from existing literatures. Individual Risk per Annum (IRPA) for individual risk and Potential Loss of Life (PLL) for societal risk were calculated from frequency analysis using Event Tree Analysis (ETA). Furthermore, the consequences were analyzed using Areal Location of Hazardous Atmosphere (ALOHA® 5.4.4) software of fire and explosion based on a worst-case scenario modeling. The individual risk per year for office workers, field workers, society and road users were 4.16E-09; 6.99E-09; 1.73E-08 and 6.59E-13, respectively. The societal risk was 1.49×10−5 per year. Compared to the UK HSE Risk Criteria, the findings showed that the individual and societal risks of each category were still acceptable and tolerable.
