The natural gas at home suddenly alarmed, there is a strong smell of natural gas, what should I do

1. Close the valve: After the alarm of the power natural gas goes off, turn off the switch of the gas stove immediately. Open kitchen doors and windows, keep the room ventilated, and turn off the power.

Check that if there are volatile gases such as alcohol around the gas stove, take them away in time. If the problem is large, you can call the gas company and ask the relevant personnel to check and manage it. 2. Replace the alarm

After solving the alarm problem of the alarm, it is necessary to turn on the switch again to restore the normal ventilation of the gas stove, and then see if the alarm will alarm. If it is still in the alarm state, check whether there is any leakage of natural gas. If it is not a natural gas leak, it may be a malfunction of the alarm, and a new one can be replaced.

3. Open the window for ventilation: and contact the maintenance personnel Natural gas leakage will cause the gas content in the kitchen to rise, and the alarm will sound. There is a lot of flammable gas content in natural gas, a large amount of leakage, and there will be a risk of fire.

Be sure to open kitchen doors and windows to keep the kitchen ventilated inside. Then contact the management department of natural gas and find maintenance personnel to come to the door for maintenance and inspection.

Close the main valve for natural gas intake. Open doors and windows for adequate ventilation. Do not use the fire source, and do not open and close the electrical switch. At the same time, ask the gas company** to inspect your gas pipeline. Find the leaks and fix them.

This requires expertise. Do not dispose of it yourself. Otherwise, there will be danger, injury to people and property, and even public safety.

First open the window for ventilation, do not have an open flame in the house, then check the natural gas pipeline, play maintenance**, find a professional, if you find a breach yourself, first take the tape to glue, and wait for the maintenance personnel to wait during the waiting period, do not stay at home.

1. Gas leakage, at this time, do not turn on the light, or ignite, or even turn off the alarm, because the gas leaks to a certain concentration, as long as there is a little bit of static electricity or open flame, it will occur ** or fire and other hazards.

In this case, you can close the gas main valve as soon as possible, and then open the doors and windows for ventilation, only after the indoor high-concentration gas is excluded from the outside, the alarm sound will automatically stop, and the follow-up needs to find out the cause of the leakage, and eliminate the solution, this process has a certain danger, so it is best to contact the professionals of the gas company to solve it.

2. Combustion is the emission of too much exhaust gas, because the gas is not completely burned in the combustion process, accompanied by the production of exhaust gas, if the exhaust gas content increases, it will affect the alarm, resulting in a sudden alarm, at this time, the possibility of danger should be eliminated in accordance with the appeal treatment method.

Natural gas alarm, there should be two situations, the first is that there is indeed a gas leak, natural gas alarm, the second is the weather false alarm is the weather alarm device has a problem,

Summary. If the natural gas alarm has an alarm, it is very likely that there is a natural gas leak, and when the leakage concentration exceeds the minimum limit of the alarm, an alarm will appear. At this time, all the indoor doors and windows should be opened, and then run to a safe area, and contact the relevant maintenance personnel to deal with it.

The gas alarm will only alarm in the case of gas leakage, and the gas shut-off solenoid valve will automatically cut off the gas source after the gas alarm alarm, so as to achieve safe gas use.

Dear, hello shed trembling talk, your hole in this question by me to help you answer, is answering for you, please wait a while, don't be too anxious, I hope my chain touch answer can help you, solve your troubles, I wish you a happy life, good health.

Hello, the gas alarm will not alarm if the house is overheated.

If the natural gas alarm has an alarm, it is very likely that there is a natural gas leak, and when the leakage concentration exceeds the minimum limit of the alarm, an alarm will appear. At this time, all the indoor doors and windows should be opened, and then run to a safe area, and contact the relevant maintenance personnel to deal with it. The gas alarm will only alarm in the case of gas leakage, and the gas shut-off solenoid valve will automatically cut off the gas source after the gas alarm is discharged, so as to achieve safe gas use.

If there is no leakage of gas, but the smell in the air is heavier, such as more seasonings, or more chili peppers, the smell is stronger, and the natural gas alarm will be more sensitive.

The reason for the natural gas alarm is that a natural gas leak is detected, and the second is a false alarm caused by the aging of the alarm.

There are two reasons why a natural gas alarm can go off:1. If the natural gas report is faulty and the alarm is empty, and the false alarm caused by the failure of the internal sensor, it is recommended to contact the manufacturer for after-sales maintenance.

2. If the concentration of combustible gas in the space is still within the alarm range, the gas valve should be closed immediately and the window should be opened for ventilation.

How to deal with the natural gas alarm alarm:

1. Please open the doors and windows immediately, turn off the hazardous gas source, and do not turn on or off any electrical switches.

2. Immediately report to the gas management department that the hunger is over, and the professionals will check and deal with it.

3. After being processed by professionals, the alarm should be ventilated.

If you use natural gas at home, you may smell a smell similar to bad eggs or rotten cabbage in your kitchen, and once you smell it, you will realize that there is a natural gas leak. But the main component of pure natural gas is methane, which has no odor. So why does the user smell a foul smell?

It turns out that the natural gas has been treated before entering the house, and in order to make the natural gas leak easy for people to discover, the personnel will add mercaptan with an unpleasant smell to the natural gas, so that they will notice something strange when they smell it. Scientists say that this ability allows humans to survive in dangerous environments, and that these volatile sulfides can help us not only distinguish between good and bad food, but also how much oxygen is in the atmosphere.

Why do humans have a special sense of the smell of sulfide? Neurobiologists from the University of Albany in the United States conducted a study on this topic and published the results in the American Chemical Society. In our olfactory sensory cells, there are specialized olfactory receptors that detect the gas molecules around us.

Once the olfactory receptor senses a particular gas molecule, it transmits the information to the brain, so that the sensation of the gas is formed in consciousness.

Among them, the researchers found that a receptor called "OR2T11" is particularly sensitive to mercaptans, which may be why humans are able to smell sulfides. In addition to this, researchers have also discovered that our nasal mucus contains copper and silver. The presence of these two metallic elements is traceable, but it plays a large role in the enhancement of the sense of smell.

Without the presence of copper and silver, the ability of the OR2T11 receptor to sense gas molecules would be diminished.

Because metals tend to react with sulfides more easily, for example, if you boil an egg in a silver container, you will soon notice that the silver container turns black. Our sense of smell depends on the presence of metal elements to detect such unpleasant smells.

This is actually the taste of hydrogen sulfide added to natural gas, not the taste of natural gas itself, because methane is natural gas, itself has no taste, therefore, once the leakage of natural gas occurs, and because he has no taste, it is not easy to be noticed by others, and it is more likely to cause accidents, and hydrogen sulfide is added to natural gas, this gas will not have any interference with methane, and secondly, the gas has a pungent taste. It can be an effective warning that there is a danger of gas leakage.

In fact, this smell is not from the natural gas itself, but is added later, so that people can smell it when the natural gas leaks, find it in time, and prevent a greater disaster.

Specially added. Natural gas itself is colorless and odorless, so for safety, it adds odor to play a preventive role.

Natural gas is also known as biogas. It is fermented by some crops such as bellflower grass roots. Naturally, it will have some stinky smell. But if the smell is strong, then be careful, it may be a gas leak.

Natural gas is normally colorless and odorless.

Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.).

Natural gas is contained in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcanic gas and biogenerated gas, and a small amount also comes from coal seams. It is a high-quality fuel and chemical feedstock.

The main use of natural gas is as fuel, which can make carbon black, chemicals and liquefied petroleum gas, and propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low-molecular-weight hydrocarbons and non-hydrocarbon gases.

It is mainly composed of methane (85%) and small amounts of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). Also known as "biogas". It is mainly used as a fuel, and is also used as a raw material for the manufacture of chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oil, methanol, nitric acid, syngas and vinyl chloride.

Natural gas is compressed into a liquid for storage and transportation. Coal miners, nitric acid makers, power plant workers, organic chemical synthesizers, gas users, petroleum refiners, etc. may come into contact with this product. It mainly enters the human body through the respiratory tract.

It is a simple asphyxiating gas. When the concentration is high, it causes hypoxia due to the displacement of air, resulting in shortness of breath and loss of consciousness; In severe cases, suffocation can occur due to hypoxia. High-pressure natural gas can cause frostbite.

Incomplete combustion can produce carbon monoxide.

Is the smell pungent when natural gas burns? See if your gas appliance burns sufficiently, natural gas is odorless, and generally odorized (tetrahydrothiophene, etc.) so that the user can smell it in the event of a gas leak. If it is only the smell of combustion, the main consideration is whether the combustion is sufficient, and whether the air intake is sufficient during combustion.

Is it piped natural gas at home?

If so, then it is normal, because an odorous gas is added to the pipeline natural gas as an alarm, so that it can be smelled when it leaks.

If there is a little bit of it that doesn't burn when it burns in the house, then you can smell it.

Explain the air leak.

Inspect gas pipelines.
