Three Workers Die at Apple’s iPhone Parts Factory in India — the Latest Blow to Its Troubled Supply Chain

Three contract workers have died at a factory in southern India that makes parts for Apple iPhones, after inhaling toxic gas while cleaning a wastewater tank. The deaths are the latest in a long run of accidents, fires, protests and pollution scares at Apple’s supplier plants in India — the country Apple is counting on to reduce its dependence on China.

The three men were carrying out maintenance work inside a nano-filtration feed tank at the Tata Electronics plant near Hosur, in Tamil Nadu’s Krishnagiri district, on Monday evening, 9 November 2026. They collapsed inside the tank and were rushed to a private hospital in Hosur, where doctors declared them dead on arrival.

Police have identified the three workers as Sarathi Kumar, 28, Akmal Babu Bhai, 28, and Kaveri, 30. All three were contract workers employed through NALCO, a contractor that operates the plant’s effluent treatment plant, and all three came from villages in the Dharmapuri district of Tamil Nadu.

Apple, Tata Electronics and the Tamil Nadu state government have all launched investigations into the deaths. Police have registered a case, and the exact cause of death will be confirmed after post-mortem examinations at the Government Medical College Hospital in Krishnagiri.

What happened at the Hosur plant

The incident happened at around 5.10 pm on Monday at Tata Electronics’ Marie Gold factory near the village of Udanapalli, close to Hosur. The three workers had entered the tank to clean out accumulated sludge and silt from the plant’s effluent treatment system — the part of the factory that treats wastewater before it is discharged.

According to police, the men were exposed to poisonous gas and a lack of oxygen inside the tank. They suffocated and fell unconscious. Fellow workers pulled them out and an ambulance took them to a private hospital in Hosur, but it was too late.

Krishnagiri District Collector C. Dinesh Kumar visited the site and confirmed that the workers had died of suffocation while removing sludge from the tank. He said a full investigation had been ordered and safety standards at the plant were being reviewed.

Tamil Nadu’s Industries Minister, Virudhai Magal Keerthana, condoled the deaths and assured that the matter would be investigated.

Tata Electronics has not yet issued a public statement on the accident. Apple is set to investigate the incident, sources told Reuters. Tata and Apple both declined to comment when contacted by Reuters, as did Nalco Water, the US-headquartered Ecolab unit that operates the treatment plant.

No impact on iPhone production — this time

There has been no impact on production at the factory, because the plant was closed for the Hindu festival of Deepavali this week, industry sources said. The timing may have prevented a worse outcome: had the plant been running at full capacity, more workers could have been in the area.

But the incident raises fresh questions about safety at a site that has already had a difficult year — and about the conditions faced by the contract workers who keep India’s iPhone factories running.

The three men who died were not directly employed by Tata Electronics. They worked for a contractor, a common arrangement in Indian factories. Contract workers often do the most dangerous maintenance and cleaning jobs, and they are frequently the ones hurt when something goes wrong.

Why this factory matters to Apple

The Hosur plant is a key part of Apple’s big bet on India. Since 2017, Apple has steadily moved more iPhone production to India as it tries to reduce its reliance on China, where most iPhones have traditionally been made.

Today, two companies dominate iPhone manufacturing in India: Tata Electronics, which accounts for roughly 40 per cent of iPhone assembly in the country, and Foxconn, the Taiwanese giant, which makes up most of the rest.

Tata’s role has grown fast. The Indian conglomerate bought Wistron’s India business in 2023 and has become Apple’s most important Indian partner. The Hosur complex makes iPhone components and assembles phones, and it sits at the centre of Apple’s plan to make India its second great manufacturing base.

That plan has been hit by one problem after another.

A pattern of trouble at Apple’s Indian suppliers

The deaths at Hosur are the latest in a series of incidents at Apple supplier factories in India, stretching back years. Reuters set out the record in a factbox published on Tuesday:

• June–July 2026: A ransomware group posted more than 200,000 files stolen from a Tata Electronics iPhone assembly plant — also in Hosur — on the dark web. The stolen material included sensitive supplier information and photos of Apple’s then-unreleased iPhone 18 Pro. Tata has since restricted internal access to sensitive systems and hired a global consultant to carry out a forensic audit.
• June 2026: Tamil Nadu’s pollution control board warned Tata’s Hosur iPhone parts plant of a forced shutdown over alleged wastewater contamination of wells in nearby farmland. Tata said independent analysis showed it complied with regulatory norms, and later said the board had confirmed it had addressed all queries and dropped further action.
• January 2025: India’s National Human Rights Commission faulted labour officials for failing to adequately investigate employment discrimination at Foxconn’s iPhone plant. The probe later cleared Foxconn of any wrongdoing.
• November 2024: Foxconn ordered its Indian hiring agents to remove age, gender and marital criteria from job advertisements, after a Reuters investigation found the company systematically excluded married women from assembly jobs at its southern India plant.
• September 2024: A fire at Tata’s Hosur plant, in an area used to store chemicals, halted iPhone component production for several days.
• September 2023: Pegatron temporarily stopped iPhone assembly at its Chennai facility after a fire at the factory.
• February 2023: Foxlink, which makes iPhone chargers, suspended production at its assembly facility in Chittoor, Andhra Pradesh, after a fire caused part of the building to collapse.
• December 2021: Operations at a Foxconn plant near Chennai were halted for more than three weeks after 250 workers fell sick, sparking protests. Apple later found the facilities did not meet its required standards.
• December 2020: Workers at a Wistron plant in Karnataka destroyed property during protests over non-payment of wages, forcing the Taiwanese contract manufacturer to shut the plant for three months. Wistron sold its India business to the Tata Group in 2023.

The list shows that the problems are not limited to one company or one kind of failure. Fires, a ransomware attack, pollution complaints, labour disputes and now three deaths have all hit the same supply chain within a few years.

What happens next

Three separate investigations are now under way — by Apple, by Tata Electronics and by the Tamil Nadu state government. Police in Krishnagiri district have registered a case, and the post-mortem reports will establish the exact cause of death.

The state government will also be under pressure to answer a wider question: how did three workers end up inside a tank full of toxic gas without enough protection? The cleaning operation is reportedly carried out once every two months on a rotational basis, which means the risks were known and the job was routine — exactly the kind of task where safety procedures matter most.

For Apple, the incident is a test of the promises it makes about its supply chain. The company publishes a supplier code of conduct and says it audits its partners on worker safety. When workers die at a supplier’s plant, those promises come under scrutiny — especially when the supplier has already had a fire, a pollution warning and a major data theft in the past two years.

For India, the stakes are high too. The country has pitched itself to the world’s biggest technology companies as a safe, reliable alternative to China. Every accident at an iPhone factory weakens that pitch, and every death makes it harder to argue that the rush to build new factories is being matched by investment in worker safety.

Why it matters

The iPhone is one of the most profitable products ever made, and the people who assemble it often work in difficult and sometimes dangerous conditions. The three workers who died at Hosur were contract staff doing maintenance work — the kind of job that rarely makes headlines, until something goes wrong.

Their deaths are a reminder that behind every smartphone is a chain of factories, contractors and workers, and that the cost of a failure in that chain is measured in lives, not just in delayed shipments.

Frequently asked questions

The Tata Electronics plant near Hosur makes components for Apple iPhones and assembles iPhones. Tata accounts for roughly 40 per cent of iPhone assembly in India, with Foxconn making up most of the rest.

Will this affect iPhone production?

No impact on production has been reported, because the plant was closed for the Deepavali festival this week.

Who is investigating the deaths?

Apple, Tata Electronics and the Tamil Nadu state government are all investigating. Police have registered a case, and post-mortem examinations are under way.

Has this factory had problems before?

Yes. The same Hosur complex suffered a fire in September 2024, a pollution warning in June 2026, and a ransomware attack in June–July 2026 in which more than 200,000 files were stolen.

Conclusion

Three workers went into a wastewater tank at an iPhone parts factory on Monday evening and never came out. Their deaths are being investigated by Apple, Tata and the Tamil Nadu government, and the post-mortem results will say exactly what killed them.

But the wider picture is already clear. Apple’s supply chain in India — the great hope of its plan to move beyond China — has been hit by fires, protests, pollution scares, a ransomware attack and now a fatal accident. Each incident on its own can be explained away. Together, they raise a harder question: is the rush to build iPhones in India being matched by the safety standards the workers who build them deserve?

For the families of Sarathi Kumar, Akmal Babu Bhai and Kaveri, that question is no longer abstract. It is the reason three men did not come home on Monday night.
