Carbon monoxide (CO) is a colorless, tasteless, no stimulation, can't use facial perception of poisonous gas, can restrain the oxygen-carrying ability of blood. Carbon monoxide toxicity is mainly influence oxygen supply and utilization, the affinity of carbon monoxide and red blood cells is larger than the affinity of oxygen and red blood cells more than 300 times, hypoxia caused by the human body. When inhaled carbon monoxide, carbon monoxide into the lungs beat with red blood cells, the ability to make the loss of red blood cells carry oxygen, cause multiple organs of oxygen, result in tissue damage and even death. The average person can't self aware when accidental poisoning, often was found to have into a coma, a major injury and even death. So call it "invisible killer" of the family, and a little ?
The production of carbon monoxide, carbon monoxide is by fuel (such as gasoline, diesel oil, coal, charcoal, gas, liquefied petroleum gas, natural gas, etc.) produced by insufficient combustion. The principal causes of carbon monoxide in the home, natural gas, coal gas, liquefied petroleum gas, fuel oil, the incomplete combustion of coal; Water heater is installed improperly, exhaust gas reflux; Pipe and exhaust pipe blockage; Confined Spaces on the engine, heating, such as the garage open engine, closed doors and Windows the stove to keep warm in winter and so on.
Carbon monoxide alarm was induced by carbon monoxide sensor into electrical signals of carbon monoxide concentration in the air, the size of the electrical signals related to the concentration of carbon monoxide. Carbon monoxide alarm according to the use of sensors to classification, general component is a ? semiconductor
