Pertalite is an oil product identified as a flammable liquid that can ignite and cause flash fires or explosions. PT X, a company involved in oil distribution, employs maritime routes and tankers to transport this oil product. One of the tanker types used is the Self Propelled Oil Barge (SPOB). The high risk of fire and explosion hazards on tankers arises from the presence of extremely flammable liquids onboard. This research is a descriptive study that utilizes quantitative modeling, including company secondary data, literature reviews, and employee interviews. The data are then analyzed using the Areal Locations Of Hazardous Atmosphere (ALOHA) software based on worst-case scenarios. The aim of this study is to analyze the consequences of fire and explosion resulting from tank leaks, focusing on the thermal radiation coverage from pool fire scenarios and the overpressure threat zones or blast areas from vapor cloud explosion scenarios. The results of this study indicate that the range of consequences for pool fires reaches up to 95 meters, while vapor cloud explosions can extend up to 558 meters. Therefore, it is crucial for the company to consider the consequences of fire and explosion, maintain the existing fire safety and emergency response systems, and raise awareness among employees, the local community, and the dockyard about the potential risks of fire and explosion.
