Why do you sometimes get poisoned by using gas in a closed room?

In some coal-producing areas, the family economic conditions are relatively backward people may still use coal to bake fire, the biggest advantage of using coal to bake fire is economical, it is not convenient to use coal for heating at home, and it may also make the home very dirty, the biggest hidden danger of using coal to bake fire is gas poisoning.

If the doors and windows of the home are not opened in time, and the ventilation is not in time, it may cause gas poisoning in the family, especially in some elderly homes, because the elderly do not know how to use the baking and warming table, and the elderly do not have a strong sense of self-prevention, they may be afraid of the cold when sleeping and close the doors and windows, which is likely to lead to gas poisoning.

Gas poisoning is also called carbon monoxide poisoning.

If the person is mildly poisoned, the person may be drowsy, at this time the person's consciousness is blurred, and there is still a little consciousness before entering the sleep state, but it will soon enter the sleep state.

This is also the death rate from gas poisoning.

The reason for the high is that when people have not realized that they have been poisoned, they are already drowsy, even after realizing that they have been poisoned, the consciousness is not awake, and few people realize that they have been poisoned by gas, and then open the doors and windows to ventilate, the average person is mildly poisoned, and then slowly turn into moderate poisoning, and then enter severe poisoning.

So what are the signs that precede gas poisoning? 1. Mild poisoning:The symptoms that people present with mild gas poisoning are nausea and palpitations.

There is also weakness of the limbs, the general consciousness is still awake, there may be a brief fainting, if it is mild poisoning, it is still easier to deal with, because at this time only need to put the poisoned patient into the vent, let the gas poisoned patient breathe fresh air can let the patient relieve in time, moderate poisoning people generally do not leave any sequelae.

2. Moderate poisoning:People with moderate gas poisoning are relatively mild, because as long as the patients with moderate poisoning are in time, they generally do not leave any sequelae, and patients with moderate poisoning should be sent to the hospital in time. Patients with moderate poisoning may sweat and be unable to walk steadily.

3. Severe poisoning:The symptoms of severe gas poisoning are loss of consciousness, severe coma, incontinence, and death soon, even if it does not lead to death, it may leave very serious sequelae, such as high paraplegia.

Dementia. Gas poisoning is light and heavy. Generally, prevention is the priority, if the home is to use coal to roast the fire, you must pay attention to ventilation, otherwise it may cause adverse consequences.

Because when coal is burned, there will be a chemical reaction, sometimes with the carbon dioxide produced by oxygen combustion, there is no harm to the human body, but once carbon monoxide is produced, the room is closed and the gas cannot get out, then people will be poisoned.

Because if you bake a fire in a closed room, it is easy to burn and produce carbon monoxide because of insufficient oxygen, and carbon monoxide will poison people and die slowly.

The main reason is that if the gas is not burned sufficiently, then carbon monoxide will be produced, and carbon monoxide poisoning will occur in a confined space.

Because the gas contains a toxic gas, that is, carbon monoxide, it can be inhaled into the respiratory system after the doors and windows are closed.

Ways to burn a stove in winter to prevent gas poisoning:

1. When using a coal stove for heating in winter, the coal stove should first be equipped with a chimney, and check whether the coal stove and the chimney are leaking, whether the flue is blocked, whether it is unobstructed, and determine the direction of smoke exhaust according to the local wind direction to prevent pouring wind. When sleeping, take the stove out of the house or install a smoke extraction device. When sleeping, a person's ability to react to the external environment is almost zero.

At this time, if the soot from the stove is discharged, it is likely to cause poisoning. So either take the stove out of the house, or install smoke extraction equipment, carefully seal the fire, and clean the chimney regularly.

2. As the saying goes, "it is better to be cold and quiet, not smoky", sleep at night, do not block the damper of the fire, set up vents in the house, and pay attention to the circulation of indoor air. You must not use a brazier to burn charcoal or coking coal directly at home for heating, and you must not put the brazier in the bedroom when you sleep.

3. Be cautious when using charcoal. Wood and charcoal are often used in charcoal fires, but in rural areas, they are often served in pots or stoves, and such combustion will directly emit carbon monoxide and other carbon monoxide in the house. If the house is relatively closed, it will cause dizziness over time.

Especially when sleeping, don't use open charcoal fires for warmth. The coal stove that has just been lit is most likely to produce carbon monoxide, so the window should be opened in time for ventilation, and the fire should be sealed after the furnace fire is strong, and the fire must not be sealed with wet coal. After sealing the fire, the ash that has not been burned should be cleaned up in time.

4. The airtightness of the house should not be too good. It is best not to have a good airtightness of the house, and the newly renovated houses in the countryside should leave a certain amount of breathable space to facilitate air flow.

5. It is better not to use the stove in the house as a bedroom. In some homes, the stove may be separate from the bedroom, and although the room with the stove is relatively warm, in order to prevent accidents, you can cover a few more quilts and not sleep in the room where the stove is placed.

6. Choose the best coal for heating. The worst of coal is actually very important, some quality coal, not only smelly, but also not fully burned and accompanied by a great smell of soot, which will bring potential harm to themselves in a closed room.

Select qualified stoves, use coal stoves must be equipped with chimneys and make them complete, and install the air hopper correctly. The part of the chimney that extends out of the window should be covered with a windproof cap. Coal stoves and chimneys must be sealed.

The mouths of the chimneys erected indoors for ventilation must be wrapped with double plastic tape or black cloth tape to close them.

The vent of the coal furnace should be directly facing the direction of the door, and the vent should be properly left when the fire is sealed at night, and all the ventilation places must not be sealed, and the amount of coal burned for sealing the fire should also be moderate.

Pay attention to heating in winter

When cooking on a coal stove during the day, open the windows to allow air to circulate. It is best to use high-quality coal and honeycomb coal. Low-quality coal produces large amounts of carbon monoxide during combustion.

Before going to bed, you should carefully check whether the lid of the coal stove is tightly covered and whether the damper is closed. Do not use coal, charcoal, firewood, coke and other combustible materials for heating indoors without a chimney.

Keep the room well ventilated, and install a ventilation fan in your home as a precaution. When possible, it is advisable to install a carbon monoxide alarm.

During the treatment process, it must be noted that the rescuer must do a good job of self-protection, and if it is too late, he can cover his mouth and nose with a wet towel before rushing into the room for rescue. When the poisoned person has a heartbeat but breathing stops, rescue breaths are given continuously, and as much as possible, until the arrival of medical personnel.

Charcoal heating, if the doors and windows are closed, when the indoor oxygen is insufficient, the charcoal fire will still continue to burn, but at this time, incomplete combustion produces a large amount of carbon monoxide. When carbon monoxide is inhaled into the body, red blood cells lose the ability to transport oxygen, causing hypoxia in body tissues and producing various poisoning symptoms.

To prevent carbon monoxide poisoning, make sure that the coal or charcoal used for heating is burned out or douse the charcoal fire with water before going to bed every night. When baking the fire, the environment should be kept ventilated, the brazier should not be covered, and a chimney should be installed on the stove. Gas appliances should not be placed in inhabited rooms or poorly ventilated places, and when bathing with gas water heaters, they should also be ventilated, and the bathing time should not be too long.

A car with an air conditioner on can also produce carbon monoxide, so you can't sleep in a car with doors and windows closed.

In the unlikely event of charcoal stove poisoning, the following first aid methods should be used immediately:

1.In homes where charcoal stoves are used, windows must be opened for ventilation to ensure air circulation.

2.In case of carbon monoxide poisoning, leave the scene of the poisoning temporarily, breathe fresh air, and call for help.

3.If a person is found to be poisoned, the window should be opened immediately, the patient should be lifted away from the scene, and the clothes should be unbuttoned to keep the airway clear and warm.

4.If vomiting occurs, the patient's head should be tilted to one side, and the secretions in the mouth and nose should be cleared in time.

5.Pinch the poisoned person's middle point, Zusanli, Neiguan and other acupoints with his hands, inhale oxygen in time, and if there is suffocation, immediately perform artificial respiration and chest compression.

6.Promptly sent to the hospital for treatment.

Because coal releases carbon dioxide during the combustion process, people can be poisoned if they inhale it.

Carbon monoxide poisoning. Hypoxia.

can cause poisoning.

According to news reports:

On the morning of January 28, 2019, four men in Suzhou, escorted by friends, went to the emergency room of Suzhou Science and Technology City Hospital. Due to the cold weather, the four of them had brought charcoal basins into the share house to warm themselves the night before after burning firewood outdoors.

From 11 o'clock in the evening to 3 o'clock in the morning, it was a full 4 hours. However, when they got up at 7 o'clock in the morning, four people invariably had symptoms such as headache and vomiting, and several people felt that the situation was not good, so they immediately went to the hospital for treatment.

Charcoal is fine to burn when there is enough oxygen, but if it is closed and lacks oxygen, carbon monoxide poisoning will be generated, so do not keep the doors and windows closed when burning charcoal, and it is best to ventilate the air every once in a while.

If the house is not well ventilated, it will cause carbon monoxide poisoning, and the main component of gas is carbon monoxide, so both are carbon monoxide poisoning.

How can you be poisoned by gas with charcoal, only when the gas leaks?

If the room is not ventilated and the combustion is not complete, it will definitely be poisoned by carbon monoxide, and the poisoned person will be pink all over the body.

Gas doesn't, but it can poison carbon monoxide.

Because the toxic carbon monoxide gas is released after the coal is burned, the carbon monoxide concentration will become higher when the room is closed, and then it will be absorbed by the body, causing poisoning.

When coal is burned, it releases carbon monoxide gas, and carbon monoxide can poison people, so it is necessary to keep the air clear and not to do it in a closed room.

Carbon dioxide is released when coal is burned in a closed room, and when the amount of carbon dioxide in the air is too high, it can cause carbon dioxide poisoning.

If you burn the stove for heating, you should pay attention to ventilation to prevent flue blockage and air leakage, and when you use a briquette stove or honeycomb coal stove for heating, you must light it outside the house before moving it to the house, and move it outside the house before going to bed at night. When sleeping at night, it is best not to press the fire, if you want to press the fire, the coal should not be pressed too much, to prevent the flue from being blocked and poisoned.

When choosing fuel, it is necessary to choose high-quality coal, which not only burns sufficiently, but also reduces carbon monoxide emissions and ensures personal safety.
