A gas leak occurred at the Steel Authority of India's (SAIL) Bhilai Steel Plant in Durg district of Chhattisgarh, killing at least six people and injuring more than 30 persons on Thursday.

According to reports, poisonous carbon monoxide gas leaked through the pipes when some repair work was being carried out in a blast furnace at around 6.30 p.m. on Thursday.

At least six employees of the plant including two Deputy General Managers were killed in the incident. More than 30 people, including Central Industrial Security Force (CISF) personnel, workers and officials of the public sector plant, were injured. Eleven of them are said to be in critical condition and have been admitted in the ICU of Jawaharlal Nehru Hospital, Bhilai, while the other injured persons are also undergoing medical treatment.

A statement issued by SAIL said, "We are deeply pained to learn that six employees have lost their lives."

"As per preliminary information, the main header of Pump House No 2 which supplies water to the Gas Cleaning Plants (GCP) of blast furnaces suddenly ruptured at around 6.10 PM.This resulted in sudden loss in water pressure to the GCPs and the blast furnace gas from the scrubbers entered the water pipeline affecting the people attending the breakdown in the pump house and in the nearby area," the statement said.

"Plant Management is providing all possible care and support and efforts are on for an early liquidation from the breakdown."

Chhattisgarh chief minister Raman Singh expressed grief over the incident. "My heart goes down for families of deceased @ BSP Bhilai.In touch with Union Ministers & local administration for relief & rescue operations (sic)," he tweeted.
