A tragic incident happened in Uttar Pradesh, when five children of a family sleeping in their house choked to death due to suffocation in Amroha district. Two others in critical condition were rushed to a hospital.What happened on Monday nightAccording to the police, they had burnt a coal brazier (angithi) inside the house which could have led to the accident. Prima facie the cause of death could be due to lack of oxygen because these people had burnt a coal brazier in their room,” an official said.This incident occurred on Monday night, when seven members of the family went to sleep and when they didnt open their door till Tuesday evening, the neighbours got suspicious. They then forcefully entered the home after breaking the door.How many died in this suffocation incidentThe house belonged to Raheezuddin whose three children and two children of his relatives had died in the accident. The condition of his wife and brother is said to be critical.Upon receiving the information, a heavy police force, including Superintendent of Police Kunwar Anupam Singh, and administrative officials reached the spot and started a probe into the matter.How burning angithi or coal brazier can lead to deathBurning angithi or coal brazier releases harmful gases like carbon dioxide and carbon monoxide. In a closed room with limited airflow, continuous discharge of these gases reduces oxygen levels and can cause suffocation. Prolonged exposure to diminished oxygen due to angithi burning in an enclosed space can prove fatal.
