Bangkok authorities are urgently addressing an oil leak from a drainage pipe on Rama 3 following complaints from residents. Governor Chatchat stressed that any abnormal signs should be reported immediately via the Traffy Fondue app to ensure prompt action is taken.
On 8 Sep 2026, it was reported that on the evening of 7 Sep, Governor Chatchat Sitthiphan, accompanied by Deputy Governor Pornprom Na S. Wikitset, officials from Khlong Toei and Yan Nawa district offices, the Drainage Department, the Pollution Control Department, and rescue teams, conducted an urgent inspection beneath the elevated Rama 3 Road bridge at the boundary of Khlong Toei and Yan Nawa districts after residents reported a strong oil smell emanating from the drainage pipe.
Officials deployed oil absorbent booms to block the spread of oil within the drainage system, applied environmentally friendly oil-removing agents to dissipate the volatile odors, and conducted random air quality checks measuring volatile organic compounds (VOCs) to monitor and ensure the safety of nearby residents.
Bangkok authorities and related agencies will continuously monitor the situation, conduct investigations, and implement solutions to prevent adverse impacts on residents and the local environment.
Recommendations and guidelines for residents in the nearby area include:
Fire hazard precautions include: Strictly avoid lighting fires, smoking, or any activities that may produce sparks near drainage openings.
Advice for vulnerable groups: Respiratory patients, young children, and the elderly are advised to wear carbon masks to filter odors and chemicals initially. If symptoms such as dizziness, nausea, or difficulty breathing occur, they should move to a well-ventilated area immediately and seek medical attention.
Residents of Khlong Toei, Yan Nawa, or nearby areas who observe additional oil stains or detect unusual strong oil odors can report incidents at the Bangkok hotline 1555 or through the Traffy Fondue app, available 24 hours a day.
