Many gas poisoning accidents have occurred since the beginning of winter
Be wary of "invisible killers" to keep warm and beware of carbon monoxide poisoning
As winter has come, many accidents of carbon monoxide poisoning have occurred in our city.
On January 5, Wuhan Emergency Management Bureau reminded the general public: Winter is the season of high incidence of carbon monoxide poisoning, and attention should be paid to ventilation when using air and heating.
Enhance safety awareness and beware of carbon monoxide poisoning.
Hospital: admitted multiple patients with carbon monoxide poisoning
Since the beginning of winter, the weather has been cold, and the number of patients suffering from carbon monoxide poisoning due to roasting fires and using gas water heaters for bathing has also increased rapidly. Many hospitals in Wuhan have admitted patients with carbon monoxide poisoning.
Chenchen (pseudonym), who is almost 4 years old, lives in Gedian. His parents go to work. He and his grandfather live at home.
On the evening of December 20, 2020, Grandpa felt cold, so he burned a charcoal brazier in the bedroom and brought Chenchen to the fire to keep warm.
In order to ensure the temperature in the house, Grandpa closed the doors and windows.
Unexpectedly, the confined space allowed carbon monoxide to accumulate, and the grandparents soon lost consciousness.
At 9 o'clock in the evening, a neighbor came to deliver something. After knocking on the door, he pushed open the open door and immediately smelled a strong smell of charcoal. I saw that my grandfather and grandson were unconscious in the bedroom.
The grandfather and grandson were rushed to Hubei Province Maternal and Child Health Hospital.
Mr. Li opened a small restaurant in Houhu. After closing on January 3, he deliberately left his staff to invite them to have hot pot. Unexpectedly, everyone at the table was "put down"-carbon monoxide poisoning went into the hospital.
During the New Year's Day, a family of 3 in Shikou Food City turned on the gas stove to marinate the beef all night. Because the weather was too cold, they closed the doors and windows tightly. When the mother got up at 3 in the morning to work, they found something was wrong. 120 was sent to the emergency department of Hankou Hospital where he was diagnosed with carbon monoxide poisoning.
After emergency rescue and hyperbaric oxygen treatment, the danger has been turned into peace.
The Tianyou Hospital affiliated to Wuhan University of Science and Technology (Tongji Tianyou Hospital) admitted 9 patients with carbon monoxide poisoning overnight.
On the evening of November 28, 2020, Tianyou Hospital admitted 9 carbon monoxide poisoning patients overnight. 7 workers cooked hot pot, grilled fire, and then took turns taking a bath in the dormitory. Because of the cold weather, they closed the doors and windows for warmth and used them for bathing. The flue of the gas water heater did not stick out of the window, which would cause collective gas poisoning.
Coincidentally, that day, the emergency department of the hospital also saw a father and son with carbon monoxide poisoning.
Expert: Preventive measures should be taken to burn charcoal for heating
According to Xiao Min, director of the Critical Care Medicine Department of Tianyou Hospital, Wuhan University of Science and Technology, as the weather turns colder, more and more patients are suffering from carbon monoxide poisoning.
In winter, people close the doors and windows indoors. At this time, use coal stoves and kangs for heating, and the stove has no chimney or chimney blockage, leaks, blows, and uses gas water heaters to shower in poorly ventilated bathrooms. Carbon monoxide poisoning may occur.
Xu Hui, director of the Department of Pediatric Intensive Care Medicine of Hubei Maternal and Child Health Hospital, said that carbon monoxide poisoning is the inadequate combustion of carbon-containing substances without adequate ventilation, which produces a large amount of carbon monoxide. After carbon monoxide is inhaled by the human body, it has more energy than oxygen when combined with blood. The strong binding force leads to hypoxia in the human body, and it also appears as a cherry red lips, which is difficult to be found.
Experts reminded that the recent continuous low temperature, families who use charcoal for heating need to pay special attention to the occurrence of carbon monoxide poisoning.
To prevent the occurrence of gas poisoning, relevant preventive measures must be taken.

poisoned by carbon monoxide
Carbon monoxide is a common colorless, odorless, tasteless, and non-irritating harmful gas, known as the "invisible killer".
Carbon monoxide poisoning, commonly known as gas poisoning.
Poorly ventilated environments such as homes or production sites, gas produced by coal stoves, leaks from liquefied gas pipelines, industrial production gas or carbon monoxide inhalation in mines can all cause poisoning.
In daily life, the lack of preventive measures when using fire, heating, and bathing at home is the main cause of carbon monoxide poisoning.
Factors prone to poisoning
1. Use coal stoves, charcoal fires, earthen kangs, fire walls and other heating methods in poorly ventilated environments.
2. Improper use, improper installation or unqualified quality of gas and gas water heaters at home.
3. Gas leakage from the gas stove or gas pipe in the home.
4. Improper use, installation or maintenance of heating stoves, gas and gas equipment and ventilation devices in collective canteens, restaurants, hotels and other catering and accommodation service units.
5. Use small oil and steam generators in small closed garages or basements.
6. Vehicle exhaust emissions, long-term air-conditioned vehicles, etc.
Carbon monoxide poisoning symptoms
1. Mild poisoning: symptoms such as headache, dizziness, palpitation, nausea, vomiting, palpitations and weakness of the limbs will appear.
2. Moderate poisoning: chest tightness, shortness of breath, dyspnea, hallucinations, blurred vision, flushing, sweating, irritability, and coma gradually.
3. Severe poisoning: coma, respiratory depression, pulmonary edema, arrhythmia or heart failure appear quickly, and the patient may present a state of decortical syndrome.
How to prevent poisoning
1. For households who use coal for heating, chimneys should be installed in the indoor stoves, the chimney structure should be tight, and the exhaust gas should be good; coal stoves without chimneys should be placed outdoors at night.
Pay special attention to weather with high humidity and low air pressure, and indoor doors and windows should not be closed tightly.
2. When using gas, it is necessary to prevent pipeline aging, outgassing, and gas leakage, and prevent the flame from being extinguished during cooking, causing gas overflow.
3. Do not use obsolete water heaters, such as direct-discharge water heaters, flue water heaters, and overdue service water heaters; you must ask professionals to install water heaters, and do not install, dismantle, or modify gas appliances by yourself.
Do not close the bathroom doors and windows tightly in winter, and do not take too long.
4. Don't eat charcoal hot pot or light charcoal brazier in a closed room.
5. When driving, do not let the engine idling for a long time; when the car is stopped, do not use the air conditioner for too long; even when driving, you should always open the windows to allow the air inside and outside the car to produce convection. If you feel unwell, stop and rest immediately; When driving or riding in an air-conditioned car, if you feel dizzy, heavy, or weak in limbs, you should open the window to breathe fresh air in time; do not sleep in a car with the doors and windows closed and the air-conditioning turned on; for long-distance driving, open the internal cycle and open regularly The windows are ventilated.
Stare at five places
1. Kitchen: Do not use unqualified or overdue gas tanks and gas stoves, and check their safety regularly; do not modify gas pipes without authorization; it is best to ask professionals for the installation of gas appliances; it is best to open windows for ventilation or smoke when using Engine and exhaust fan; gas alarm can be installed if possible.
2. Living room: When using coal stoves, charcoal fires and other heating equipment indoors, the coal must be burned out, do not cover the stove with a stuffy cover, and pay attention to ventilation.
When heating with a kang stove or fire wall, always check whether the flue and chimney are blocked.
Also check the kang seams and fire wall seams, and wipe them if there is any leakage.
When using briquettes for heating, be sure to set a fire outside the house and wait for the fire to start before moving into the house.
3. Bedroom: Do not put heating equipment such as coal stoves and charcoal fires directly in the bedroom. If conditions permit, it is best to move the stove outside at night before going to bed (but pay attention to fire prevention); always open doors and windows for ventilation and keep indoor air fresh.
4. Bathroom: When buying gas and gas water heaters, you need to choose a water heater produced by a regular manufacturer with qualified quality. It must be installed by professionals and can be used after passing the test; gas water heaters and exhaust vents must not be installed in a closed bathroom. It should be installed in an outdoor ventilated place; when using gas and gas water heaters, maintain good ventilation. You can turn on the exhaust fan or open the window appropriately. Do not take too long to take a bath. Regularly check the pressure relief valve and hose of the gas and gas water heater. Carry out maintenance, and replace it in time if damage, rust, air leakage, etc. are found.
5. Charcoal hot pot: Try not to use coal, charcoal or solid alcohol for shabu-shabu or barbecue indoors. Instead, use an induction cooker; if you need to use charcoal, it is best to place it in a ventilated hall or keep doors and windows open for ventilation.
Common sense of first aid poisoning
1. After smelling the gas, do not turn on the light, touch the doorbell, or light the open flame to prevent explosion.
Ambulance personnel must ensure safety (cover their mouth and nose with a wet towel) and turn off the gas.
2. After entering the scene, immediately open the doors and windows, and quickly move the poisoned person to a safe and well-ventilated place. The principle is to save people first.
3. Transfer the poisoned person to a ventilated place, dial 120 emergency number and 119 fire number, indicating that it is gas poisoning.
120 will give priority to sending poisoned patients to hospitals with hyperbaric oxygen conditions for treatment.
4. Keep the head of the poisoned person to one side to ensure the airway is unobstructed, prevent the vomit from suffocating the airway, untie the collar and belt, raise the lower limbs of the poisoned person, ensure that blood is given priority to the heart and brain, and reduce the activity of the poisoned person. At the same time provide warm measures.
5. Judging the symptoms of poisoned patients. For those with mild coma, you can pinch the middle point to promote awakening.
In severe coma, if there is cardiac or respiratory arrest, immediately perform CPR, do not give up easily.
special reminder
It is not only the burning of coal, charcoal, and gas that carbon monoxide is produced. Incomplete combustion of carbon-containing substances can produce carbon monoxide, triggering safety incidents.
