When using natural gas, should we first turn off the gas or the fire?  A lot of people are doing it wrong 

Natural gas is a colorless and odorless energy source, so in the process of use, if there is a natural gas leak, they can not be detected, this is a disadvantage of using natural gas. 

So the correct use of natural gas is very important, today, to say, the use of natural gas is to turn off the gas and then turn off the fire?  Or do you want to turn off the heat first and then the gas? 

In our daily life, many people think that we should turn off the gas first and then turn off the fire later. 

Because after the use of natural gas, there will still be residual natural gas in the gas pipe. If the fire is turned off first, the natural gas will not be used up, which will be more wasteful, and will volatilize into the air, which will also cause harm to our bodies. 

In fact, this approach is wrong, there are a lot of potential dangers. 

The right way should be to turn off the fire first, then turn off the gas! 

Gas cooker in the use of the process, you can adjust the size of the flame through the button, and the gas pipeline above the valve is to control natural gas, if not on the fire to close the valve first, the flame will drill into the pipeline, so that it will cause safety accidents. 

So don't waste the gas and do the wrong operation. 

And if you cook at home, you will generally use a gas stove many times. If you always operate in this way, the valve of the gas pipeline will be damaged, which will increase the risk of gas leakage. 

When you use natural gas at ordinary times, the correct approach should be to turn off the fire first, and then turn off the gas.
