According to the Ministry’s data, 122 people in Uzbekistan lost their lives to carbon monoxide poisoning in 2022, with 84 reported incidents. In 2023, 46 cases were recorded, and 32 have already been reported this year. The surge in such cases as winter nears highlights the pressing need for awareness and preventive action.
Hikmatullayev explained the science behind CO poisoning, a phenomenon often occurring due to inadequate ventilation and faulty heating systems. He noted that CO can rapidly fill enclosed spaces, replacing oxygen and making breathing difficult. Once inhaled, CO binds with hemoglobin in the blood, preventing oxygen from reaching vital organs. Even a short exposure can cause a person to lose consciousness or, in severe cases, lead to death.
"We live because of oxygen, and if the brain lacks oxygen for just a few minutes, fatal consequences are inevitable," he said. “A single cubic meter of burning gas can consume the oxygen in ten cubic meters of air. As oxygen depletes, it is replaced by CO, causing a dangerous buildup in enclosed spaces.”
The deputy head emphasized the role of modern, airtight home designs in contributing to CO risks. In older construction, a small gap under doors allowed fresh air to enter, maintaining airflow and preventing CO from accumulating indoors. However, modern homes often use tightly sealed doors and windows, which, if not properly ventilated, can trap CO.
“Our heating systems require airflow from outside,” Hikmatullayev stressed. “Without it, CO accumulates, and ventilation alone is insufficient. This can lead to CO buildup, increasing the risk of poisoning.”
Describing the symptoms of CO poisoning, Hikmatullayev noted that affected individuals may feel weakness, dizziness, and eventually lose consciousness as the poison gradually takes effect. Because CO has no color, odor, or taste, its accumulation is difficult to detect, making it a "silent killer."
With colder days approaching, Hikmatullayev urged citizens to prepare heating systems in advance. Many cases, he explained, arise from neglecting chimney and ventilation cleaning, as well as improper use of stoves.
He recommended calling emergency services at 104 or 1050 for guidance before lighting stoves and utilizing volunteer fire safety services to ensure chimneys are clean and functioning.
As Uzbekistan braces for winter, authorities are actively encouraging citizens to take preventive measures to avoid further tragedies. By understanding the risks and ensuring proper ventilation, they hope to mitigate the risks associated with carbon monoxide exposure.
