Thailand's Pollution Control Department is investigating an ongoing oil spill in the Khlong Toei area (Fuel Road) that has detected volatile organic compounds (VOCs) at 626 ppm and flammability levels (LEL) at 2–18% in drainage pipes. Authorities have halted oil pipeline operations, opened excavation sites to locate the leak source using DCVG technology, and are conducting Oil Fingerprint analysis to trace the origin. Small oil traces were found at 2.5 meters depth; repairs are expected to take approximately 5 days. Public safety measures include mask recommendations and fire-risk activity avoidance.
