Winter Invisible Killer - Carbon Monoxide

First, why should we guard against carbon monoxide poisoning in winter?

In the cold winter, everyone needs heating. If the coal is heated, the indoor concentration of carbon monoxide is high and it is very easy to cause carbon monoxide poisoning. After carbon monoxide enters the human body, 85% binds to human hemoglobin of red blood cells to form carbon monoxide-hemoglobin, which mainly causes tissue hypoxia, disordered organ metabolism, and even necrosis. Therefore, we must guard against carbon monoxide poisoning in winter.

Carbon monoxide poisoning is divided into occupational and non-professional. The carbon monoxide poisoning mentioned here refers to non-professional, that is, carbon monoxide poisoning in everyday life.

Second, the common cause of carbon monoxide poisoning in daily life

1 , use coal fire heating or soil heating.

2. Improper use of gas tanks and gas water heaters.

3 , Ladle lid is not strict, the flue is blocked, and the adjacent flue smoke crosses.

4 , the chimney installation is not reasonable, the mouth is facing the tuyere.

III. Carbon Monoxide Poisoning and Meteorological Conditions

Weather conditions such as low temperatures, snowfall, and high winds make it difficult for everyone to close doors and windows and cause air to circulate.

Low atmospheric pressure, indoor accumulated gas cannot be discharged in time.

Fourth, the main performance of carbon monoxide poisoning

1 , headache

2 , dizziness

3 , flustered

4 , facial flushing

5 , general body force

6 , blurred

7. Obscure vision

8 , feeling slow

9 , breathing difficulties

10 , coma

Fifth, how to save carbon monoxide poisoning?

1. When using coal stove heating or liquefied petroleum gas water heaters to take a bath, if you feel dizziness and chest tightness, open doors and windows as soon as possible.

2. If you feel that your body is unable to stand, you must climb up and crawl, open doors and windows quickly, and call for help.

3. If you find poisoning, use a wet towel to cover your mouth and nose, and turn off the gas. No open fire can occur. Do not switch appliances.

4. Raise the poisoned person quickly to the ventilated place, loosen the collar and keep the air unblocked.

5 , severe cases to artificial respiration or cardiac compression, and call 120 emergency.

Six, carbon monoxide weather index (in four levels)

Level 1 : More conducive to carbon monoxide diffusion

Level 2 : Call it benefit carbon monoxide diffusion

Level 3 : Not conducive to carbon monoxide diffusion

Level 4 : Extremely bad for carbon monoxide diffusion
