Three contract workers died Monday evening while cleaning an effluent treatment plant at Tata Electronics Private Limited in Krishnagiri district, India, local media and Xinhua report.
The incident occurred during routine maintenance of the plant’s wastewater treatment facility, a site where hazardous gases can accumulate if ventilation is inadequate.
Local outlets first reported the deaths in an evening bulletin on Monday, and Xinhua published the story on Tuesday, noting the asphyxiation caused by inhalation of a toxic gas.
ETV Bharat’s coverage adds that the workers had allegedly inhaled toxic gas inside a wastewater treatment tank at the same manufacturing facility, suggesting a possible failure of gas detection or safety protocols.
So far, the Tata Electronics corporation has not released an official statement, and authorities have not opened a formal investigation into the cause of the fatalities.
The incident has prompted calls from workers’ unions for stricter safety measures and improved monitoring of hazardous atmospheres in industrial plants across India.
