The Assam Oil India explosion death toll has risen to three. Two more workers injured in the blast and fire at Oil India Limited's Intermediate Tank Farm in Tengakhat, in Assam's Dibrugarh district, died in hospital on Saturday, November 7, a day after the explosion ripped through the facility during maintenance work. Tapas Jyoti Gogoi, 40, who had suffered around 70 per cent burns, died at around 3 am on Saturday, and Rupam Gohain, a resident of Chabua, died at around 11 am after being shifted to a hospital in Guwahati. The first fatality, Raju Dutta, 45, died on Friday, the day of the explosion. Nine workers were present at the site when the blast happened, and seven of them were injured.

Assam Oil India Explosion: What Happened at Tengakhat

The explosion happened at around 9.05 am on Friday, November 6, while maintenance work was under way at the Intermediate Tank Farm, known as the ITF, at Tengakhat. A massive fire broke out immediately after the blast, and photographs from the site showed workers running from a huge fireball as thick black smoke rose over the facility. Preliminary reports suggested the explosion took place in the crude oil storage section while a valve was being operated, though Oil India has not yet confirmed the exact cause.

Nine workers were present at the site when the accident occurred. Seven of them sustained injuries, while two escaped unhurt. The injured were first taken to Assam Medical College and Hospital in Dibrugarh, and later shifted to a private healthcare facility. The workers were employed by Spectron Engineering Private Limited, a Mumbai-based company engaged by Oil India for maintenance work at the facility.

Who Were the Three Workers Who Died?

Raju Dutta, 45, was the first to die. He was killed on Friday, reportedly thrown by the force of the explosion. Tapas Jyoti Gogoi, 40, a resident of Milan Nagar in Dibrugarh, died at around 3 am on Saturday at a private hospital in Dibrugarh. He had suffered around 70 per cent burns, and the cause of death was recorded as cardiorespiratory failure. Gogoi had worked at the facility for around 13 years and is survived by his parents, his wife and his daughter. Rupam Gohain, a resident of Chabua in Dibrugarh district, died at around 11 am on Saturday at a private hospital in Guwahati, where he had been shifted for advanced treatment. Some reports spell his name as Rupam Gogoi.

Injured Workers Still in Critical Condition

Three to four injured workers were still receiving advanced medical treatment on Saturday afternoon, with one or two of them in critical condition, according to the latest reports. The injured may be shifted outside Assam for specialised treatment if doctors recommend it. Union Minister Sarbananda Sonowal called Oil India's Chairman and Managing Director to take stock of the explosion and fire, and urged the best possible medical care for the injured. Kamal Phukan, area manager of Spectron Engineering Services, said the company would provide compensation to the affected workers.

What Caused the Assam Oil India Explosion?

The exact cause of the explosion and fire, as well as the extent of damage to the oil storage facility, remains unclear. Oil India's statement said only that the fire broke out during maintenance work at the Intermediate Tank Farm. The incident has raised questions over safety protocols and emergency preparedness at Oil India installations. Local organisations, including the All Assam Tai Ahom Students' Union, have questioned the company's safety preparedness and alleged negligence, though the cause has not yet been established.

What Happens Next After the Tengakhat Fire

The immediate focus is on the medical care of the injured workers, with the possibility of shifting them outside Assam for specialised treatment if doctors advise it. Beyond that, the incident is expected to face scrutiny over what went wrong during routine maintenance work, and whether safety procedures were followed. Oil India has not yet announced the findings of any internal inquiry, and has not commented on the allegations raised by local organisations. Updates on the injured workers and the cause of the explosion are expected as the investigation progresses.
