Six workers at a dyeing and printing mill in India were killed and more than 20 were taken to hospital on Thursday after inhaling toxic gas caused by an illegal dump of waste chemicals, officials said.
India toxic gas leak kills 6 after illegal chemical dump
The disaster took place in the industrial city of Surat in Gujarat state at about 4 a.m. The workers were in the mill when some chemicals were dumped nearby, police and a fire officer said.
"Chemicals were being illegally discharged from a tanker into a rivulet close to the mill, which possibly reacted with another chemical in the water and created toxic gas," the chief fire officer of Surat Municipal Corporation, Basant Pareek, told Reuters.
"The workers inhaled the gas and started feeling suffocation. When we reached the scene, the workers were found collapsed on the road in their attempt to escape."
Six workers died while 23 people were hospitalized, seven in critical condition and on ventilators, Pareek said.
Senior police official Sharad Singhal said officers were investigating but had yet to make any arrests.
"This was not an accidental gas leakage. Hazardous chemicals were being discharged when the incident took place," he said.
India suffered the world's worst industrial disaster in 1984 when methyl isocyanate gas leaked from a pesticide factory owned by American Union Carbide Corporation in the city of Bhopal, killing more than 5,000 people.
