INDRAMAYU, KOMPAS.com - A powerful explosion occurred at one of the tanks of Indonesia's Balongan oil refinery owned by the state oil firm Pertamina in Indramayu regency, West Java on Monday, March 29.
Pertamina Subholding Refining and Petrochemical Corporate Secretary Ifky Sukarya said the fire was suspected to have been caused by lightning that occurred in the early hours of Monday.
"The tank at the RU VI Balongan refinery caught fire at 00:45 am. It occurred during heavy rain and lightning, then the T-301G tank caught fire," Ifky said in an interview with Kompas TV, Monday.
On the other hand, West Java Police chief Inspector General Ahmad Dofiri revealed that the fire was due to a suspected leakage or refinery seepage.
However, the Forensic Laboratory Center (Puslabfor) of the National Police Headquarters officials are still investigating the cause of the explosion.
"[Puslabfor] has been deployed to the scene and will start an investigation after the fire has subsided. Later there are steps to identify the source of the fire," said Dofiri Monday.
Currently, he added, the fire at Pertamina RU VI Balongan refinery has been slightly dimming.
Indramayu Regent Nina Agustina said all parties have stepped in to evacuate residents, including the Health Service and the Fire Service in Indramayu. More than 1,000 residents were displaced to three temporary evacuation shelters, namely the Indramayu Regent's Hall, the Islamic Center, and the Bumi Patra Indramayu Housing Sports Hall.
"They must have panicked as no one expected this fire incident. Approximately 1,000 people from Balongan, Majakerta, and Sukahurip were displaced at the three shelters," said Nina Agustina.
