Volkswacht Bodensee - 13 dead, 38 injured in explosion at nickel plant in Indonesia

The island of Sulawesi is a hub for the mineral-rich country's production of nickel, a base metal used for electric vehicle batteries and stainless steel, and Beijing's growing investment has stoked unrest over working conditions at its facilities.

The accident occurred around 5:30 am (2130 GMT Saturday) at a plant owned by PT Indonesia Tsingshan Stainless Steel (ITSS) in the Morowali Industrial Park in Central Sulawesi province, a spokesperson for the complex said in a statement.

"(The death toll) increased by one person, from 12 to 13," he told AFP, also revising the number of injured down one to 38.

He identified the dead as eight Indonesians and five Chinese workers.

An initial investigation showed the explosion happened during repair work on a furnace when a flammable liquid ignited and the subsequent blast caused nearby oxygen tanks to explode as well, the official said.

The fire was extinguished Sunday morning, according to the statement.

Tsingshan Holding Group, the world's biggest nickel producer and China's biggest stainless steelmaker, holds a majority stake in ITSS.

ITSS is a tenant in the industrial park, which is also majority owned by Tsingshan along with local partner Bintang Delapan.

The firm that runs the industrial park said it was "deeply saddened by this disaster, particularly for the families affected".

It said the remains of several identified victims had been flown home.

Footage shared with AFP showed plumes of smoke emerging from the facility with emergency services at the scene and workers looking on.

A photo shared with AFP showed the bodies of the victims lined up on top of orange body bags in a room in one of the clinics at the industrial complex.

"Their faces were burnt, their clothes were all burnt," a worker at the industrial complex told AFP on condition of anonymity.

Acting Morowali district head Rachmansyah Ismail told broadcaster Kompas TV that as of Sunday afternoon 25 of the injured -- 15 Indonesians and 10 foreign nationals -- had been immediately rushed to hospital after the blast.

Seventeen were seriously injured while eight suffered moderate injuries, he said.

In January, two workers including a Chinese national were killed at a nickel smelting plant in the same industrial park after a riot broke out during a protest over safety conditions and pay.

Deadly fires are not uncommon in Indonesia, a sprawling country of more than 250 million people where safety regulations are often flouted.

In June a fire at the same plant left one dead and six others injured, in another incident that has stoked concern over safety at facilities funded and operated by Chinese companies.

The facility where the riot and fire took place is operated by PT Gunbuster Nickel Industry (GNI), a local unit of China's Jiangsu Delong Nickel Industry.
