How does carbon monoxide poison people?
The mechanism of carbon monoxide poisoning is that the synthesis of carbon monoxide and hemoglobin is 300 times higher than that of oxygen and hemoglobin, so carbon monoxide can easily combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its oxygen-carrying ability and function and causes tissue suffocation. It is toxic to tissues and cells all over the body, especially the cerebral cortex. Once you realize the occurrence of carbon monoxide poisoning, it is often too late. Because the cerebral cortex, which controls human movement, is paralyzed first, people can't carry out purposeful autonomous movement. You can handle it easily. Therefore, patients with carbon monoxide poisoning often cannot save themselves effectively.
What causes carbon monoxide poisoning?
Most of them are because the coal stove has no chimney or the chimney is not blocked, or the wind blows into the chimney, which makes the gas enter the room reversely, or because there is no ventilation equipment in the room. The smelting workshop is poorly ventilated, and the exhaust gas from internal combustion engine and gunpowder explosion contains a lot of carbon monoxide. Industrial steelmaking, ironmaking, coking, chemical synthesis, ammonia, formaldehyde, etc. Contact with oxygen. In the course of life, burning coal indoors for heating or taking a bath with a gas heater may cause carbon monoxide poisoning.
How to prevent carbon monoxide poisoning?
Indoor coal fires should be widely publicized to explain possible symptoms of gas poisoning and common sense of first aid. Do not use water heaters such as direct-row water heaters and flue water heaters that are prohibited from production and sales by the state. There is no water heater that is out of service. It's best to ask professionals to install heaters, and you can't install, disassemble or refit gas appliance yourself. Don't close the bathroom doors and windows when taking a bath in winter, and don't take a long shower. When driving, the engine must not idle for a long time. Don't turn on the air conditioner for too long when the car is parked. Even when driving, always open the window to let the air inside and outside the car convection. If you feel uncomfortable, stop and have a rest.
