Turn off the gas or the fire first after using the gas stove

The practice of turning off the gas stove first is correct, first turn off the gas stove, and the fire source will be extinguished, so as to avoid the potential safety hazards such as fire and ** of suction, because after the use of gas, there will still be some gas residue in the gas pipe, if the gas tank is turned off first, the pressure outside the pipe is greater than the pressure inside, and the resulting backfire is very dangerous. Turning off the fire first will only cause some gas waste and will not be too dangerous.

In addition to cleaning the surface of the stove with a wet cloth after each cooking, the outer ring tooth cover, nozzle, stove head and other positions should be cleaned every month or so to avoid dirt blockage.

Regular cleaning can ensure the service life of the gas stove.

Close the tank first and then turn off the fire, so that the gas left in the pipe will also be burned out.

Close the main valve on the tank first.

Turn off the switch on the stove after the residual gas is burned.

The gas stove is a kind of stove, which is mainly located in the gap between the stove and the upper cover to supplement the lack of air during combustion, so as to promote combustion and reduce the generation of carbon monoxide and nitrogen oxides.

The air intake mode of gas stove is divided into upper air inlet, lower air inlet, full air intake, etc., which can be divided into multiple types according to different classification standards.

When the gas is not in use, the gas stove should be turned off before the gas tank valve is closed. If the gas tank valve is closed first and then the gas stove is turned off, it is easy to cause gas backgasp, which will cause potential safety hazards. Many users will habitually close the gas tank valve and then turn off the gas stove after using up the gas, thinking that there is still gas in the gas pipeline, and the gas can be used up and then turned off to save gas.

In fact, this not only does not save gas, but also easily buries potential safety hazards.

Because the gas is filled into the gas tank by compression, it will suck the gas in the gas tank when the gas tank is closed first, and the gas stove is still in a burning state, so it is easy to suck the flame down along the gas tank, so be sure to close the valve of the gas stove first.

Precautions for the use of gas stoves:

1. After the gas stove is used, the main valve of the gas source and the knob on the table must be turned off immediately, otherwise there may be gas leakage, which will cause life danger.

2. Whether cooking or boiling water, people should not leave, otherwise the time is too long, the water will overflow, and the fire will be extinguished.

3. If there is a smell of gas in the house, do not bring it into Mars, or smoke, otherwise it is likely to cause a disaster.

4. If you smell a gas smell in the house, but the gas stove has been turned off, you should find a gas company to check the problem.

5. If you find a gas leak in the house, remember not to test it with fire, use soapy water, wipe it on the pipe, if the air leaks, it will inevitably bubble, wrap it with a damp cloth or cotton cloth, which can temporarily block the gas leakage in a large area.

The gas tank should be turned off first, and then the stove should be turned off, and there is no gas in the leather tube from the tank to the stove when not in use.

The correct order to answer is to turn off the gas cylinder first, and then wait for the fire on the stove to go out automatically before turning off the stove, which is safe. Because there will be a section of hose connection between the liquefied gas stove and the liquefied gas tank, if the stove switch is turned off first, there will be some gas left in the hose, once the leakage occurs, the gas will be dispersed into the air, which is very dangerous, and if it encounters an open flame, the consequences are even more unimaginable.

If you turn off the gas tank first and then turn off the stove after using the gas, there will be no residual gas in the hose, which will be relatively safe, of course, if it is only temporarily turned off, and then you have to continue to use it, it doesn't matter if you turn off the stove first and then close the tank.

Dear, there are many aspects to pay attention to when using gas at home, such as the service life of gas cylinders is generally 15 years, if you exceed this time, remember to replace them in time, many people look at the surface of the gas tank There is no problem, they are reluctant to change, but in fact, the interior may have been corroded. In addition, do not disassemble the gas tank without permission, and do not collide and knock, which is very dangerous.

Ask if the gas tank will return to fire if it is turned off first.

1. When using gas, the gas source is usually turned off first to prevent tempering;

2. However, if the gas stove has functions such as flame-out protection, and the gas with low pressure is used, such as natural gas, which is usually 2000pa, it does not matter if there is no priority, and usually no user will close the gas source valve. However, for safety reasons, other gases should be switched off first, especially if the pressure is high and relative to a closed gas source.

You can turn off the fire temporarily, as long as you turn off the gas stove switch, if you don't use the fire, it is recommended to turn off the gas.

When turning off the gas stove, you should turn off the gas first and then turn off the fire, so that there is no residual gas in your pipes. It does not pose a hidden danger.

For household gas stoves, passing and turning off the gas is carried out at the same time. FYI.

Turn off the gas stove first and then turn off the valve. Closing the valve first may cause the fire source on the gas stove to enter the gas pipe with the gas, which will not only damage the gas pipeline and valve, but may even cause safety accidents such as **. Therefore, when using the gas stove, you must develop the habit of turning off the fire first and then closing the valve to avoid accidents.

Precautions: 1. The gas pipeline and gas pipeline switch valve should be tested from time to time to prevent gas leakage.

2. Develop a good habit of using it in daily life, turn off the fire first and then close the valve.

3. There is an open flame when cooking, and people should not leave for too long to prevent doing other things and forgetting that the vegetables are still burning in the pot.

4. If you are using a gas tank at home, and find that the flame becomes smaller when cooking, do not shake and move the tank body easily.

5. The kitchen should be ventilated by opening windows frequently.

Turn off the gas first, and when the gas is turned off, the fire will naturally be extinguished. Usually, when we use gas, if we turn off the fire first, it is easy to forget to turn off the gas, and there will be potential safety hazards if the gas is not turned off. If you accidentally leak gas, it is easy to happen** and pose a threat to life, so we must develop a good habit of turning off the gas first and then turning off the fire, so that it is much safer to use gas.

It's easy to use gas incorrectly, so you should usually do the following:

1. Regularly inspect the gas pipeline for leaks or signs of aging.

If the gas pipeline leaks, then it is easy to encounter fire**; The aging of the gas pipe, which is broken by a mouse bite, can also cause **. If this kind of gas ** had happened at night, the casualties would have been terrible. In particular, if you run a restaurant or snack bar, the gas usage rate is very high, so it is important to ensure that the gas pipes do not leak, otherwise not only your own store will suffer, but also the store next to it will not be spared.

2. When turning off the gas, wipe your hands clean first, don't get wet.

This is also to ensure the safety of themselves and their families, and many families still use gas to cook. Then when using it, you should pay attention to these details, and your hands must be dried before you can turn off the gas. Otherwise, the water droplets in the gas tank will have potential safety hazards, and if it is ** one day, it will be too late to run.

3. The gas tank should be separated from the cooking position by a certain distance, and it cannot be placed directly next to it, which is too dangerous.

Nowadays, many snack bars have very small stores, and sometimes they just put four or five gas canisters next to them. The stir-fry fire here is so big, and the gas tank is so close, I generally don't dare to stay in this kind of shop for a long time, for fear of not paying attention, and it doesn't meet the safety standards of opening a restaurant. When we are at home, we also have to keep the gas tank farther away to be safe.

When using gas, be sure to do the above so that the risk can be minimized. When cooking a meal, turn off the gas first and then turn off the heat, not only for yourself, but also for other members of the family to develop this habit in order to ensure the safety of the family.

As a housewife, the individual still has a very right to speak, of course, the gas stove must be turned off first, and then the gas, only in this way can the safety hazards be reduced.

The gas stove should be turned off first, because if the fire is turned off first, some gas will remain in the pipeline, and it is very dangerous if it leaks.

It is best to turn off the gas stove first and then turn off the gas, because this is the step we usually usually do, which will be more convenient, if you turn off the gas first, it is actually relatively cumbersome.

When we use the gas stove in our house, we always turn off the gas before turning off the fire, because when the gas is turned off, the fire will be extinguished, so it is also convenient to check whether the gas is closed tightly to avoid hidden dangers.

According to the regulations of the gas company, it will be safer to turn off the gas first and then turn off the fire, so you should pay more attention when using it.

I think it depends on each habit, if it were me, I would choose to turn off the heat first, and then turn off the gas, how do you do it? There is no fixed statement.
