Gas poisoning usually refers to carbon monoxide poisoning. When burning carbon-containing substances on a daily basis, it should be prevented by maintaining ventilation, setting up safety equipment and other measures. Carbon monoxide poisoning is usually caused by inhalation of the products of incomplete combustion of carbon-containing substances through the respiratory tract. Therefore, maintaining air convection and installing necessary safety equipment, such as chimneys and hoppers, can better prevent carbon monoxide poisoning. Carbon monoxide poisoning is mainly due to the fact that carbon monoxide easily combines with hemoglobin to form carboxyhemoglobin, causing hemoglobin to lose its ability to carry oxygen, resulting in tissue asphyxia. Therefore, you need to be aware of the need for prevention in your daily life. If you find yourself suffering from carbon monoxide poisoning, such as headache, dizziness, fatigue, difficulty in breathing, blurred consciousness, etc., you need to stay away from the poisoned environment immediately, and if the situation is not relieved, you should call the emergency number and seek medical treatment.
