Nearby residents breathed a sigh of relief after a gas leak at a factory owned by Indorama Ventures Plc in Nahon Pathom on Thursday morning was quickly contained.
The leak of two toxic chemicals -- diphenyl oxide and biphenyl used as heat transfer fluid -- was brought under control within 10 minutes. But the smell from the leak was reported as far as 20km away from the factory and the government ordered a number of schools and universities to close due to safety concerns.
