1.In the early winter, every family would use a stove. When the coal in the stove burned violently in the air, it was generally not easy to produce carbon monoxide due to contact with oxygen.
Because carbon monoxide is carbon monoxide produced by carbon and carbon dioxide. Carbon burns completely in the air because it contacts more with oxygen and less with carbon dioxide, so it is difficult to produce carbon monoxide. However, in the closed environment of the furnace, it is easy to contact carbon dioxide and produce carbon monoxide. This is what we often call gas poisoning.
2.In hot summer, we feel sleepy when driving. Sometimes we park our car on the side of the road to have a rest for safety. This is right, but it may be more dangerous than driving when you are sleepy, that is, turn off the windows and turn on the air conditioner. The reason why it is dangerous is that the engine idles when the car is parked in place and the air conditioner is turned on. At this time, due to insufficient combustion, a large amount of carbon monoxide will be generated. In addition, without opening the window, the air in the car can only convection through the air conditioner, and the carbon monoxide generated by the engine enters the car, resulting in danger.
This is the news that often reports the death of poisoning by turning on the air conditioner in the car in the summer news conference
3.In addition to the above two kinds of carbon monoxide, carbon monoxide will be inhaled unconsciously when indoors. For example, the kitchen will produce carbon monoxide. When cooking, carbon monoxide will also be produced due to incomplete combustion of fuel.
This is carbon monoxide poisoning in the kitchen.
4.There is also a frequent problem to be said, that is, inhalation of second-hand smoke.
Smoking will produce carbon monoxide, xylene, benzaldehyde and other complex components, in which the content of carbon monoxide accounts for about 20%, but regular inhalation will also have a fatal risk.
5.Usually, there are some natural coal production in industry. Incomplete combustion of coal will produce carbon monoxide. The worse the oxygen supply conditions, the higher the carbon monoxide content. Carbon monoxide is also emitted during the processing and coking of gas and water gas.
