Background and Objective: Diesel storage tanks play a crucial role in hospitals and are constantly at risk of chemical release, explosion, and fire. The purpose of this study was to examine the consequences of a diesel tank leak in one of the Iran’s specialized hospitals.
Materials and methods: This study utilized an applied research approach with scenario modeling using PHAST software version 8.4. A discharge rate of 1000 L/min was employed for the fixed-duration release scenario. The necessary information for the software, including tank and meteorological data, was collected. The mortality rate and danger radius were calculated and analyzed for two tank volumes of 23600 and 12000 m3 in conditions of Sabzevar region in winter and 1.5 F of the software.
Results: According to the tank type and substance release into the environment, the software showed a pool fire. The most hazardous scenario was determined to be leakage from the 23600 m3 tank in Sabzevar's weather conditions (26 0C, wind speed 15 m/s in winter). The maximum and minimum radiation heat from the fire were calculated at 44.7 and 94.2 meters, respectively. The mortality rates for exposure levels of 37.5 kw/m2, 12.5 kw/m2, and 4 kw/m2 were found to be 98.7%, 6.5%, and approximately zero, respectively.
Conclusion: Fire safety in hospitals is a critical issue that requires a thorough examination of the factors that can lead to ignition and explosion.
