As winter approaches, gas poisoning incidents pose a serious threat to people’s lives and property. Therefore, people must pay attention to preventing gas poisoning in winter.
First, we must eliminate the following misunderstandings in our hearts to prevent being careless in these aspects and causing gas poisoning.
1． Only burning coal can cause poisoning. All carbon-containing fuels, such as gasoline, kerosene, charcoal, etc., can produce a large amount of carbon monoxide when they cannot burn due to lack of oxygen, so they can also cause gas poisoning.
2. The absence of soot indoors will not cause poisoning. Gas is a colorless, odorless gas. The absence of soot in the room does not mean there is no gas. Gas poisoning occurs unconsciously.
3. Seal the fire with wet coals or put a basin of water in it will not cause gas poisoning. In fact, carbon monoxide is extremely difficult to dissolve in water; moreover, water and coal will react chemically at high temperatures to form a mixed gas called water gas, which contains a large amount of carbon monoxide and has a high specific gravity. It is more likely to persist indoors, increasing the risk of poisoning.
4. Roasting date cores and orange peels on the stove can detoxify coal. Roasting these aromatic substances on a coal stove can only increase the fragrance in the room, but cannot absorb gas and prevent poisoning.
5. Installing a chimney will prevent gas poisoning. In fact, gas poisoning can also occur when strong winds blow smoke, the chimney is blocked by soot or other things, and the gas cannot be discharged or the gas is discharged in a small amount and most of it spreads indoors.
6. Installing a wind bucket will not cause gas poisoning. Many people use old air ducts, or the air ducts are too small or the installation height is not high enough. Due to poor exhaustion of gas, poisoning can also occur.
7． Gaps in doors and windows will not cause gas poisoning. The specific gravity of air is 1 and the specific gravity of gas is 0.967. Outdoor air is heavier than gas. If the gaps between doors and windows are at a low level, it will be difficult for gas to escape. Therefore, gas poisoning may also occur if there are gaps in doors and windows.
8. Burning liquefied petroleum gas will not cause gas poisoning. Liquefied petroleum gas is heavier than air. If the gas leaks from the stove, it will easily accumulate in low places, and gas poisoning will occur if it is inhaled into the body.
9. Filling with vinegar and pickled cabbage soup can save poisoned patients. For gas poisoning patients, especially those who are in a coma, forcing vinegar or pickled cabbage soup into their mouths can easily choke into the lungs and block alveolar gas exchange, leading to aggravation of the condition or even death.
10． Gas poisoning patients will be fine after being rescued. Gas poisoning causes great damage to human lungs, heart, brain and other organs. If the rescued patients are not treated carefully, they are likely to have sequelae.
Second, ventilation protection must be done. Be sure to put out the fire before going to bed.
Third, when using pipeline gas, prevent pipeline aging, gas leakage, and gas leakage. When cooking, prevent the flame from being extinguished and causing gas to escape.
Winter is a period of high incidence of carbon monoxide poisoning incidents. Carbon monoxide poisoning incidents occur almost every winter and spring, seriously threatening people's health.
1. How to identify carbon monoxide poisoning
Carbon monoxide is a colorless, odorless gas. Carbon monoxide in daily life mainly comes from the use of gas stoves, stoves, coal-fired heaters, fuel-fired engines, etc.; wood charcoal such as stoves and braziers are used for heating in prefabricated houses and temporary housing, which is more likely to produce carbon monoxide. The symptoms of carbon monoxide poisoning are related to the concentration of carbon monoxide in the air, the length of exposure, and your health. Early symptoms include: severe headache, dizziness, palpitation, facial flushing, cherry-red lips, general weakness, nausea, vomiting, drowsiness, confusion, blurred vision, insensible feelings, hallucinations and other symptoms. If the symptoms of poisoning can be identified at this stage and the patient can be removed from the poisoning environment, he can recover quickly. If you continue to be in a toxic environment, the condition will progress further. Poisoned persons will have symptoms such as difficulty breathing, loss of consciousness, coma, and slow pupillary light reflex and corneal reflex. If the condition worsens further, severe poisoning will occur: deep coma, loss of pupillary light reflex and corneal reflex, inability to respond to calls, and inability to move when pushed. This stage is often accompanied by serious complications such as cerebral edema, pulmonary edema, and shock, and the mortality rate is extremely high.
Carbon monoxide mainly affects blood function, reducing its ability to transport oxygen. It also affects cell function, making them unable to utilize the oxygen delivered. Due to lack of oxygen, it can cause harm to the brain and heart, and even lead to death. Even if patients with severe poisoning are rescued, they will be left with permanent brain damage symptoms.
2. Carbon monoxide poisoning has the following symptoms:
Mild or moderate poisoning: fatigue, fatigue and drowsiness, headache, dizziness, confusion, nausea, vomiting, chest pain, etc., with rapid heartbeat at the beginning.
Severe poisoning: lowered body temperature, confusion, slowed or even irregular heartbeat, lowered blood pressure, irregular breathing or even respiratory arrest, leading to death. Patients diagnosed with carbon monoxide poisoning should take the following measures:
After entering the room, you should quickly open all doors and windows, turn off the gas switch, etc. Move the patient from the poisoning site to a place with fresh air, and loosen his collar and belt to facilitate his breathing. For unconscious patients, the head can be turned to one side to prevent vomitus from being accidentally inhaled into the lungs and causing suffocation. If the patient is not breathing, perform mouth-to-mouth artificial respiration immediately and call“１２０”Emergency center, send the patient to the hospital for rescue as soon as possible.
3. There is a risk of carbon monoxide poisoning under the following circumstances:
(1)． Using gas stoves, stoves, coal-fired heaters, or burning objects in rooms without windows and other ventilation ducts, especially in closed board houses and temporary housing, can easily cause carbon monoxide to accumulate and lead to poisoning.
(2)． The use of improperly installed gas water heaters can also easily cause carbon monoxide to accumulate indoors, leading to poisoning.
4. How to prevent carbon monoxide poisoning
To prevent carbon monoxide poisoning in winter, you should do the following:
(1) In family life, the coal must be burned out, do not cover it, and a chimney must be installed on the coal stove. Especially in cloudy days or rainy and snowy weather in winter, coal combustion is incomplete, and the outdoor air pressure is low, which makes it difficult for indoor carbon monoxide to be discharged. It is strictly prohibited to use charcoal braziers, stoves and other heating appliances in board houses and temporary resettlement houses for heating; therefore, precautions must be taken at home to avoid accidents.
(2) When using a natural gas water heater, do not close the room, maintain good ventilation, and do not bathe for too long. When using a stove or burning items, be sure to open windows for ventilation, and it is best to turn on the exhaust device at the same time. When using a gas water heater, you must find a professional installer to install it. It is strictly prohibited to install the water heater in the shower room. Check gas pipelines and gas equipment frequently. If there is any leakage, stop using it immediately and contact the gas company for repairs immediately. Stove equipment must be supervised when in use.
(3) When using pipeline gas, prevent pipeline aging, gas leakage, and gas leakage. When cooking, prevent the flame from being extinguished and causing gas to escape. In winter, avoid going to entertainment venues as much as possible, especially those who like to entertain themselves in karaoke boxes. They should also pay attention to avoid carbon monoxide poisoning. Although most karaoke boxes have ventilation equipment, the space in such places is relatively airtight; especially in winter, air conditioning or heating is usually turned on in the boxes and the doors are closed. If there are many people smoking in a small space, it is easy to produce carbon monoxide, which poses a risk of poisoning. Therefore, attention should be paid to maintaining ventilation in the box.
