CO Gas：
The mechanism of carbon monoxide poisoning is that the affinity between carbon monoxide and red Du protein of Bai blood is 200-300 times higher than that of oxygen and hemoglobin. Therefore, carbon monoxide is easy to combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose the ability and function of oxygen carrying and cause tissue asphyxia. It has toxic effects on the tissues and cells of the whole body, especially on the cerebral cortex. The key to prevent carbon monoxide poisoning is to keep ventilation. For those who use coal for heating, chimneys should be installed in the fire stoves in their rooms. The chimney structure should be tight and the smoke and exhaust should be good. Coal stoves without chimneys should be placed outdoors at night. Air humidity, low pressure weather should pay special attention to indoor doors and windows do not close too tight
