How much do you know about natural gas?

The coverage rate of pipeline natural gas is getting higher and higher.

It is very convenient to get natural gas into your home.

But hidden dangers should not be ignored.

Natural gas properties

The main component of natural gas is methane.

Colorless, odorless, non-toxic, and non-corrosive.

Methane is harmless to the human body.

But it has a suffocating effect.

Methane (CHâ‚„).

When gas companies supply gas, they add the odorant tetrahydrothiophene to make it easier for users to detect.

As long as there is a small amount of natural gas leaking.

People will smell a special odor.

When its concentration in the air reaches 10%.

It can cause suffocation and death.

When the content of natural gas (methane) in the air reaches 5-15%.

It will explode when it encounters a fire source.

During the combustion process of natural gas,

carbon monoxide (CO) and carbon dioxide (CO2) will be produced.

Carbon monoxide (CO) gas is extremely harmful to the human body. Its binding force with hemoglobin in the human body is greater than that with oxygen, which will cause hypoxia in human tissues, resulting in suffocation. In severe cases, it will cause internal bleeding, edema, and necrosis.

Due to the characteristics of carbon monoxide, it is difficult for people to perceive its existence. When symptoms such as dizziness and nausea occur after poisoning, even if you realize that it is carbon monoxide poisoning, you often have lost the ability to control your actions and cannot open windows for ventilation or call for help. If you are not discovered at this time, there is a high possibility of death.

Carbon dioxide (CO2) is an odorless and sour colorless gas, which is a product of natural gas combustion. Carbon dioxide has an anesthetic effect and can irritate the skin and mucous membranes.

The content of carbon dioxide in fresh air is 0.04%, which is harmless to the human body. When the combustion exhaust gas fills the room without compensating fresh air, the indoor carbon dioxide increases and the oxygen content decreases relatively, which can cause suffocation.

The density of natural gas is lighter than that of air. Even if it leaks accidentally, it will quickly evaporate in the air and is not easy to accumulate. Although the probability of causing various gas accidents is relatively small, for safety reasons, a vent should be left in the kitchen all year round.

Selection and installation of gas stoves and hoses

The installation of gas stoves and connecting hoses must be carried out under the guidance of professionals, or ask the technicians of the gas company to install them. Do not operate privately. After installation, be sure to use professional instruments or soapy water to apply to each joint and valve to check for leaks. Only after ensuring that there are no leaks can they be used.

When purchasing gas stoves and hoses, be sure to choose standardized manufacturers and brands. Do not be greedy for cheapness and cause disasters. Climate policies are reshaping global natural gas consumption.

Precautions for natural gas during use

1
When using gas, do not leave without permission. Ventilation should be maintained to prevent poisoning by carbon monoxide and carbon dioxide produced by natural gas combustion; it meter installation site also needs to be ventilated and cannot be closed.

2

Please do not heat overfilled cookers on the gas stove to prevent water from overflowing and extinguishing the flame, causing gas leakage.

3
If the gas supply is suddenly interrupted, the valve should be closed until the normal gas supply notification is received before continuing to use it.

4

Regularly check whether the gas pipeline is leaking. If a leak is found, turn off the main valve in time and contact the gas company staff to deal with it. Do not deal with it privately.

5

The switch of a stove that has been used for a long time may not be closed tightly, which will cause gas leakage. The switch needs to be replaced in time.

6

When not using it, close the main valve and branch valves, and open the kitchen doors and windows to keep ventilation.

7

Install and use a gas leak alarm device to ensure home safety.

8

Regularly contact the natural gas company to check for leaks and check for safety hazards.
