The method used for this paper is descriptive method with secondary data about the storage tank. This paper use qualitative risk assessment result that fire risks for WT16 the storage tank is high. Then based on the calculation of the ALOHA software in getting the results of the thermal radiation in tank number 3 have 71 meters with 10 Kw/m2 intensity of radiation, 97 meters with 5 Kw/m2 intensity of radiation, 147 meter with Kw/m2 intensity of radiation and for tank number 2 have 68 meters with 10 Kw/m2 intensity of radiation, 94 meters with 5 Kw/m2 intensity of radiation, 142 meters with 2 Kw/m2 intensity of radiation. Then, a safe distance by calculating using the acceptable separation distance calculator results obtained within safe for humans 179, 16 meters and 35.38 meters for buildings for tank number 3 and for the tank number 2 the safe distance is at 128, 60 meters for humans and 24, 48 feet for the building.
