The weather turns cold to prevent carbon monoxide poisoning

release time:2022-04-27|reading:

      Acute carbon monoxide poisoning is most common in winter heating season.

  In the severe cold season, many people or restaurants close doors and windows, resulting in poor indoor air circulation.

  Therefore, whether using coal (wood, gas) stoves for heating, cooking, or using gas water heaters for bathing, it is easy to produce a large amount of carbon monoxide, leading to poisoning.

天气转冷,预防一氧化碳中毒

  Exhaust gases from the engine or generator can also cause carbon monoxide poisoning.

  Carbon monoxide is a colorless, tasteless and non irritating asphyxiant gas.

  Coal, liquefied petroleum gas, natural gas, etc.

  When the combustion is incomplete, carbon monoxide will be produced.

  The oxygen inhaled through the human respiratory tract needs to be delivered to the whole body, but carbon monoxide can occupy the delivery space more than oxygen, so carbon monoxide inhalation will cause hypoxia and poisoning, which is highlighted by cerebral hypoxia symptoms, such as dizziness, headache, nausea, vomiting, fatigue, etc., which can cause coma and death in serious cases.

  How should we prevent and deal with

  What about acute carbon monoxide poisoning?

  The CDC management experts gave the following suggestions:

  1. Ensure good ventilation of firewood, charcoal fire, coal fire, gas heating and other environments.

  It is strictly prohibited to close doors and windows and ventilate regularly. If necessary, gas fans and gas alarms can be installed.

  When using the gas water heater, the bathroom and the room where the water heater is located should be kept ventilated, and the washing time should not be too long.

  2. The stove in the living room should be equipped with a chimney to strictly prevent the chimney from leaking and blocking. The exhaust gas should be unblocked. The outlet of the chimney should be away from the wind.

  3. Try to use firewood, charcoal, coal fire and gas stove in the environment and living room without air circulation, such as the ceiling, walls, doors and windows and underground pipes should not be connected.

  Some residents were poisoned by the gas from the roof of the boiler house to the roof of the bedroom during heating at home.

  4. Start up. If the car is on fire for a long time and does not start, open the window to prevent poisoning caused by exhaust backflow.

  Don't sleep in a car with the air conditioner on and the windows closed.

  Turn on the air conditioner when parking, and pay attention to the gaps in the windows.

  5. Emergency information processing of acute carbon monoxide poisoning.

  If a patient is conscious, he or she should be able to move to the ventilated window or door as soon as possible to breathe fresh ambient air. At the same time, he or she can ask for help from others, call 120 or go to the nearest hospital as soon as possible.

  If we find that the life of the patient has been affected and there is no sense of innovation, the rescuer should immediately transfer the patient to a place where he can breathe fresh air, open the doors and windows, and it is best to breathe oxygen; Keep the patient from lying flat and turn his head to one side to prevent vomit from being inhaled into the airway by mistake; Call 120 in time or send the patient to the hospital as soon as possible; keep warm.
