Natural gas is a gaseous fossil fuel composed mainly of methane. It is mainly found in oil and gas fields, and also in small quantities from coal seams.
When non-fossil organic matter decays anaerobically, it produces a methane-rich gas called biogas. Biogas includes swamps between forests and meadows, landfills, sewers, and manure, which are produced by the anaerobic decomposition of bacteria. Biogas also includes gases (eg
Fart), gastrointestinal gas most commonly comes from domestic animals such as cattle and sheep.
So please rest assured, natural gas is harmless, leakage is not the same as gas leakage, it will not be dangerous, Answer added No, besides, can they stop work if you stop it, don't worry, there will be no problems, natural gas is much more 'cute' than gas, you have heard of gas**,,, have you heard of hydrogen**, have you heard of natural gas**, and it is impossible to dig the pipeline, because the pipeline is empty and not inflated in the construction state.

As long as the valve is not opened, it is safe, since it is a natural gas terminal, there should be relevant departments to check; It is feasible only if the inspection is qualified;

What are you afraid of, people are not afraid to work there, you are afraid.

Moving speed. To be safe! The answer adds: It is recommended that you still move well! In case he has any enemies, by the way! Oh.

Sub-high pressure B (the distance between the natural gas valve and the house is 5 meters, and the safety distance meets the requirements of the national standard GB 50028-2020 table, and the auspicious shed.
If it is sub-high pressure a (it does not meet the requirements. Be cautious of defeat.

The minimum vertical safety distance between an overhead gas pipeline and a power cable is, Cwise.
The overhead power line with a voltage of less than 3kv is meters, and the overhead power line with a voltage of 3 10kv is a meter.
Overhead power lines with a voltage of 35-66kV are meters, see the GB 50028-2020 table for details.

Hello dear! According to GB 50187-2012, the pressure of the gas pipeline is less than or equal to the minimum safety distance, the pressure of the gas pipeline is less than or equal to the minimum safety distance, the pressure of the gas pipeline is less than or equal to the minimum safety distance, the pressure of the gas pipeline is less than or equal to the minimum safety distance, the pressure of the gas pipeline is less than or equal to the minimum safety distance.
Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry: >>>More
Hello, if you have a handle-style valve, rotate the valve handle to 90 degrees in the counterclockwise direction, parallel to the pipe, it means that the gas has been turned on. >>>More
1. The natural gas valve is open for "smooth" pipeline, and "horizontal" is closed. The following is a diagram of the opening valve. >>>More
For safety reasons, the natural gas valve can be closed every day. >>>More
It is best to close the valve of natural gas after each use. Because the hose is generally used when the natural gas in the kitchen is connected, the hose itself is relatively short in terms of service life, if the natural gas valve is not turned off frequently, it will cause the corrosion and aging of the hose, so that the phenomenon of air leakage may occur after a long time. Once there is a gas leak, it may cause poisoning, and it may even cause ** phenomenon. >>>More
