The Pollution Control Department reports fuel vapour (VOCs up to 626 ppm, LEL 2-18%) in storm drains on Chueang Phloeng Road, Khlong Toei. The fuel pipeline was shut from 8 Sep 2026 and repairs are estimated at about 5 days once the leak is found; supply through the pipe is suspended. Officials ask everyone to check LEL before entering confined spaces, avoid spark-causing work and smoking nearby. If your business is on or near this road, plan for possible fuel supply delays and keep staff away from drains and open trenches. Oil fingerprint testing is pending to identify the source.
