CITU seeks inquiry into role of Tata Electronics in death of three workers due to asphyxiation
On November 9, 2026, three workers engaged in cleaning work inside the nano-filtration feed tank at Tata Marigold Company in Krishnagiri district died of asphyxiation
The CITU (Centre of Indian Trade Unions) has called for a comprehensive investigation into the deaths of three workers at Tata Electronics Marigold plant in Vanniyarpuram, Nagamangalam, due to asphyxiation inside a nano-filtration tank. The trade union is seeking to determine if Tata Electronics, as the principal employer, played a role in the incident and if the company adhered to the safety protocols mandated by the Occupation Safety, Health and Working Conditions Code, 2022.
The union questions whether the cleaning of the ETP qualified as a confined space, and if the necessary safety measures such as a gas detector, an oxygen meter, and proper safety gear were in place for such work. They also query if the trapped door for removing sludge was used instead of entering the tank.
The CITU's inquiries follow the registration of a negligence case against Arjunan, a contractor of Nalco Water, who had subcontracted the ETP to Perma Tech Private Limited. The police registered the case on Wednesday. Despite the families of the deceased receiving a compensation offer of ₹30 lakh each from Nalco Water, the CITU treasurer believes the amount is insufficient.
