A man who suffered severe burn injuries in a fire sparked by a gas leakage in Siddhirganj upazila in Narayanganj district six days ago, died early Saturday.

Six others injured in that fire remain in critical condition at National Institute of Burn and Plastic Surgery.

The deceased was identified as Hannan, 40, a native of Shariatpur`s Zajira upazila and had been living with his family at Siddhirganj. He was a rickshaw driver by profession.

He succumbed to his wounds around 1 AM on Saturday, confirmed Shawon Bin Rahman, resident surgeon at emergency department of National Institute of Burn and Plastic Surgery.

He had been admitted to the high dependency unit (HDU) with burns on 45 percent his body, he said.

“Hannan passed away. His two daughters, Samia and Jannat, are now out of immediate danger, according to doctors. However, his wife Lucky and son Sabbir remain in critical condition,” said Anwar Hossain, Hannan`s brother-in-law.

Earlier, the fire broke out around 2:30 AM on Mar 3 in a tin-roofed house owned by Ibrahim Khalil in the Paschim Dhankunda area. Eight people from two families suffered severe burn injuries in the incident.

The injured include Hannan`s his wife and garment worker Nurjahan Akhter Lucky, 30, their daughters Jannat, 3, and Samia, 9, son Sabbir, 16. The other victims are garment worker Sohag, 23, his wife Rupali, 20, and their one-and-a-half-year-old daughter Sumaiya. They were all rushed to the burn institute in the wake of the incident.

According to doctors, Sabbir had burns on 27 percent of his body, Lucky on 22 percent, Samia on 7 percent, Jannat on 3 percent, Rupali on 34 percent, Sumaiya on 44 percent, and Shohag on 40 percent.

Dr Nasir Uddin from the institute said that six of the victims had suffered airway burns, putting them in critical condition. They were receiving treatment in the HDU.

Abdullah Al Arefin, deputy assistant director of Narayanganj Fire Service and Civil Defence, said that a gas line ran beneath the two-room tin-roofed house. A leakage likely caused gas to accumulate inside and a spark ignited the trapped gas, causing an explosion that triggered the fire.

“Everyone was asleep when the fire broke out. They were burnt before they even had a chance to escape,” said fire service official.
