Firefighters in Bangkok are conducting a continuous 24-hour surveillance of an oil leak affecting drainage systems along Chuea Phloeng Road and under the Rama 3 elevated bridge. The incident prompted a response from the Khlong Toei Fire and Rescue Station, who are monitoring the contaminated area. Authorities are preparing to excavate the ground to access and thoroughly inspect an underground oil pipeline thought to be the source of the leak. The goal is to identify any potential defects or damage that may have caused the contamination. This operation aims to mitigate further environmental impact and prevent escalation of the situation in Bangkok. The leak is currently contained under observation while the inspection process is prepared.
