How to turn off domestic natural gas is the safest

1, it is best to install an air leakage alarm, which is mainly composed of key components such as harmful gas probe and electromagnetic cut-off valve. When the indoor harmful gas reaches a dangerous concentration, it will automatically cut off the gas supply valve, which is intrinsically safe, especially in the case of poor indoor ventilation in winter.

2. Connect the gas valve and stove with reliable special gas hose and clamp.

3. It's best to find out the usage norms and requirements of "three first, three later, eight no two tight and one pass" for domestic natural gas, and use it in strict accordance with the requirements.

4. If you are a frequent gas user, remember to check the closed state of the main valve after using gas every day. Remember.

Civil gas is three before three, eight is not allowed, two is tight.

(a) after the first three:

1, ignite first and then open the gas;

2. Kill first or leave later;

3. Check before you rest.

No:

1, can't ignite without a stove;

2, naked flammable materials in the room are not allowed to ignite;

3. No one is in charge, no ignition is allowed;

4, pipes, valves, furnace gas leakage are not allowed to ignite;

5, gas pipeline trunk valve switch at will;

6. Don't light a fire while sleeping;

(3) two close links:
