A smelting furnace exploded Sunday at a Chinese-owned nickel plant in Palu on Indonesia’s Sulawesi island, killing at least 13 workers and injuring dozens of others, police and a company official said.
It was the latest in a series of deadly incidents at nickel smelting plants in Indonesia that are part of China’s ambitious transnational development program known as the Belt and Road Initiative.
Nickel is a key component in global battery production for electric vehicles.
At least four Chinese and nine Indonesian workers died when the furnace exploded while they were repairing it, said Central Sulawesi police Chief Agus Nugroho.
The blast was so powerful that it demolished the furnace and damaged parts of the side walls of the building, said Nugroho, adding that about 46 workers were injured, including four Chinese nationals, some in critical condition.
Authorities are working to determine whether negligence by the company led to the deaths, Nugroho said.
Cause of explosion under investigation
The accident occurred at PT Indonesia Tsingshan Stainless Steel, a subsidiary of PT Indonesia Morowali Industrial Park, known as PT IMIP, in the Bahodopi neighbourhood of Morowali regency.
“We sincerely apologize for this incident and we are working closely with authorities to investigate what caused the accident,” said company spokesperson Deddy Kurniawan.
Rescuers extinguished the fire and evacuated workers after a nearly four-hour operation, he said.
A preliminary investigation showed there were explosive liquids at the bottom of the furnace that triggered a fire and then a subsequent explosion in nearby oxygen cylinders.
It was the third deadly incident this year at the plants in Central Sulawesi province, which has the largest nickel reserves in Indonesia:
Two dump truck operators were killed when they were engulfed by a wall of black sludge-like material following the collapse of a nickel waste disposal site in April.
In January, two workers, including a Chinese national, were killed in riots that involved workers and security guards at an Indonesia-China joint venture in North Morowali regency.
Last year, a loader truck ran over and killed a Chinese worker while he was repairing a road in PT IMIP’s mining area. An Indonesian man burned to death when a furnace in the company’s factory exploded.
Nearly 50 per cent of PT IMIP’s shares are owned by a Chinese holding company, and the rest are owned by two Indonesian companies. It began smelter operations in 2013 and is now the largest nickel-based industrial area in Indonesia.
In March, three Chinese workers filed a complaint to Indonesia’s National Commission on Human Rights, alleging their health is deteriorating due to dust and smoke exposure while working seven days a week without a break at PT IMIP. They added that workers there don’t have adequate safety equipment.
Data collected by the Mining Advocacy Network, an Indonesian watchdog, showed that at least 22 workers from China and Indonesia have died in nickel smelting plants in Central Sulawesi province since 2019, including two Chinese nationals who took their own lives.
