What safety knowledge is necessary when using natural gas?

Nowadays, most households do not use gas stoves, but use natural gas. Although natural gas is more convenient when used, it may also cause many safety hazards if it is not used properly. Therefore, it is very necessary to master some safety knowledge about natural gas.

When using the gas stove, it is necessary to keep the windows fully open for ventilation, so that the indoor and outdoor air can be circulated in time. The gas stove used must be a big brand, so that it is safe and secure, and there will be no gas leakage. <>

When people use gas, they must buy qualified products, and they must not be greedy for cheapness, because the quality of low-cost products is likely to be not up to standard. In this way, in the process of use, it is likely that there will be insufficient combustion, deflated, and leakage. Serious impact, people's physical and mental health, and when using gas, people must stay next to the gas stove throughout the whole process, and can not leave at will.

Otherwise, it may also occur that the ignition suddenly turns off and causes gas poisoning. <>

After cooking, be sure to turn off the gas stove in time. Especially if there are elderly people and children at home, if they are not at home for a long time, then it is also necessary to close the main valve of the gas in time. In addition, professional personnel should be required to come to the home and regularly check the gas pipeline to see if there is aging.

If there is aging, then it should be replaced in time to try to eliminate some unnecessary safety hazards. And in the process of using a gas stove, you should know that whether it is a gas stove or a water heater, the age should not exceed 8 years. <>

Once it is more than 8 years old, it should be replaced with a new one in time, which can also avoid hidden dangers. The location of gas installation is also particularly important, it is best to install it in the balcony, kitchen and other locations, and must not be installed in the bathroom, living room, bedroom, dining room, etc., otherwise it will cause a great impact. If there is an abnormality in the leakage, gas or use of gas, you should call the gas company in time for timely maintenance.

1.Take close care when using gas. In the process of using the stove, people should not stay away to prevent gas leakage caused by the boiling soup overflowing or the wind blowing out the stove.

2.After using the gas, the valve is turned off and the gas is cut off. After using gas, the stove switch and the valve in front of the stove should be closed to prevent gas leakage.

3.Check it up regularly. Always check the hose connection to see if it is fixed with clips and whether the hose is aged or cracked.

When using natural gas, be careful, do not light an open flame next to natural gas, open the valve first when using, and ignite it. Pay attention to adjust the size of the damper of the flame, the normal flame is blue, if it is not blue, it should be adjusted.

When using natural gas, it is necessary to maintain ventilation in the room, someone should check the gas appliances at all times to avoid fires, the gas facilities should be checked frequently and replaced in time, and the valves must be closed when there is no one at home.

Hazards: fire, poisoning.

Harmful factors: Here you want to ask about the harmful factors of occupational diseases? If so, the answer is that there are no harmful factors of occupational diseases.

Protective measures: aWhen operating: the direction of opening the valve: slowly open each valve from the air supply end of the pipeline to the air end, the speed can not be fast, and the pressure reducing valve, filter, etc. will be damaged. When the valve is closed, it goes in exactly the opposite direction.

b.Do not knock on pipes and valves.

c.Principle: high temperature, open flame.

d.Take fire and explosion-proof measures indoors, and do not pile up any combustible substances.
