New Delhi/Krishnagiri, Three workers died in an incident at a utility facility operated by Nalco Water at a Tata Electronics factory in Hosur, Tamil Nadu, which makes components for Apple iPhones.

The deaths occurred when three contract workers suffocated while cleaning a wastewater treatment tank at the facility, police said on Tuesday.
The deceased Kaveri of Hosur, B Akmal and M Sarathi Kumar , both hailing from Dharmapuri district were exposed to lethal poisonous fumes and severe oxygen depletion while desilting an effluent treatment plant storage tank on Monday evening.
Akmal initially peered into the tank to inspect it, only to collapse immediately from gas exposure.
Attempting a rescue, Kaveri directed Sarathi Kumar to check on their fallen colleague, but he fainted upon entry. Kaveri then rushed inside the enclosure himself, succumbing to the toxic atmosphere moments later.
A fourth crew member who observed the tragedy unfold alerted nearby staff.
Rescuers pulled all three individuals from the tank and rushed them to a private hospital in Hosur, where doctors declared them dead on arrival.
The remains were subsequently transferred to the Government Medical College Hospital in Krishnagiri for post-mortem examinations.
