FIRE AND EXPLOSION CONSEQUENCE ANALYSIS ON LPG (LIQUEFIED PETROLEUM GAS) TANK IN PT SURYA ESA PERKASA TBK PALEMBANG

Abstract

Background: LPG plant has fires and explosions hazard which can occur due to a processing, storing, or distributing failure. PT Surya Esa Perkasa Tbk is one of LPG plant in Indonesia which has a high risk of fire and explosion due to leakage of the 150 tons capacity tank. Therefore, it is necessary to analyze the consequences of fire and explosion on the LPG tank in PT Surya Esa Perkasa Tbk Palembang. Method: This study was a descriptive research with quantitative approach. The consequence analysis will be made jet fire, fireball/BLEVE, flammable area/flash fire, and vapor cloud explosion (VCE) modeling by using ALOHA (Areal Location of Hazardous Atmosphere) software 5.4.4 version. The farthest threat zone will be analyzed to know the number of population at risk and analysis of emergency response plan (procedures, teams, facilities and infrastructure) which had been applied. Result: Jet fire modeling threat zone reached 150 meters, BLEVE modeling reached 1.3 kilometers, flammable area modeling reached 911 meters, and VCE modeling reached 398 meters. Population at risk was 81 workers. The application of emergency response plan (ERP) from procedure, team, and facilities aspects had been good but there were no ERP intended for surrounding communities. Conclusion: BLEVE modeling has the farthest consequences reaches 1.3 kilometers with 81 people as population at risk and ERP had been well implemented by PT Surya Esa Perkasa Tbk for workers but it still had no ERP for surrounding community. Keywords: working population at risk, emergency response plan.
