The facts
Three contract workers died on 9 November while maintenance was being carried out at an effluent-treatment plant at Tata Electronics’ facility near Hosur, Tamil Nadu; the plant makes components for Apple iPhones. [2][3][4]
Krishnagiri district collector C Dinesh Kumar said the company was directed to submit a detailed report on the accident, identified lapses and corrective and preventive measures. Tamil Nadu safety and pollution-control officials were inspecting the site. [1][2][3]
The collector said the treatment plant would be allowed to resume only after authorities verified required safety measures and issued clearance; he said proper safeguards were not in place during the maintenance work. [1][2][3]
Police said preliminary inquiries suggested possible toxic-gas inhalation, but the cause of death would be established after postmortems. No final cause has been reported. [2][3]
Reuters reported no production impact at the time because the facility was closed for the Deepavali holiday; the broader Tata Electronics plant was not ordered shut. [1][4]
Still unconfirmed
- The final cause of death and the substance, if any, involved are not established; police said postmortems were needed.
- The results of the state safety inspection and any final findings on responsibility or corrective action are not yet known.
