The Pollution Control Department (PCD) is watching petrol stations, fuel tanks, and chemical or hazardous waste stores in flooded Bangkok and other disaster areas, because rising water can damage tanks or pumps and spread contamination. PCD asks operators to inspect sites, tanks and equipment closely during the flood. If you find damaged containers, leaks, oil sheens or chemical smells, report them promptly and keep people away from the area. Public pollution reports go to hotline 1650.
