Raebareli NTPC power plant Over 50 people are said to be injured in the boiler pipe explosion
Congress vice president Rahul Gandhi said he was disturbed by the incident and urged the authorities to provide all help to the injured.
The 1,550 megawatt (MW) plant supplies electricity to nine states, according to the company's website, and employs 870 people.
The explosion reportedly took place in a boiler of the 500MW thermal power plant. The blast spewed hot ash over the plant workers. He said injured are also admitted at local PSC, district hospital and private hospitals in Raebareli.
Unofficial reports pegged the number of the injured at 150.
The Sub-Divisional Magistrate Unchahar confirmed the death of four labourers. In a statement, NTPC said around 10 people sustained serious injuries. The man said he was unable to understand what had happened and found himself on a hospital bed with his body scalded all over, when he regained consciousness. By night, the plant was blanketed in heavy security.
"It's believed that accumulation of ash inside pipe and furnace of the boiler exploded due to pressure at the power plant", a senior official at Raebareli told Xinhua. "All available ambulances have been pressed into action", the Uttar Pradesh Police said in a tweet.
The anger among the residents of villages near the plant was palpable.
Gandhi represents the Raebareli parliamentary constituency in the Lok Sabha. This appears to be a very unusual incident because NTPC has a high record of safety.
Labour union leader Ram Dev Singh alleged that safety measures were overlooked and the management was apathetic towards the plight of workers.
Chief Minister Adityanath, who is away in Mauritius on a three-day official visit, has ordered that necessary steps be taken for rescue and relief.
The state government will also give Rs 50,000 for critically injured while Rs 25,000 for those who have suffered light injured.
The scene outside the NTPC plant and at the hospitals was chaotic.
