Oil and gas industries are categorized as high risk activities. Fire and explosion incident in LPG storage tanks illustrates the high safety risks of LPG storage tanks at oil and gas processing facilities. PT XYZ is an oil and gas company that has LPG storage tanks, which also has a potential of fire and explosion incident, therefore it is necessary to study the possible impact of fire and explosion incident. This research was conducted to analyze safe distance, and modeling the size of fire and explosion of LPG storage tanks at PT XYZ, and determine the appropriate control measure to reduce the impact of the incident, using ALOHA (Areal Location of Hazardous Atmospheres) Software simulation. The result of this study can also be an input for the Company to ensure the level of safety and reliability of their installation.
There were 3 (three) steps in this research, such as: identification of fire and explosion incident scenario in the LPG storage tanks, the range of fire and explosion modeling of the LPG storage tanks, and the safe distance analysis of LPG storage tanks to other facilities in the vicinity.
The results of the research showed that explosion and fire of the tank caused the spread of heat radiation to the farthest distance 188 meters from the location of the leak. The worst impact for residents of the settlement is the potential to cause second-degree burns with a thermal radiation level of> 5.0 kW / m2 within 60 seconds. The LPG tank explosion and fire distance models are: a distance of 0- 1.3 km high risk; 1.3-2.8 moderate risk; and> = 2.8 km low risk.
