What detects gas leaks?

1.Use your nose to smell. Smell gas contains hydrogen sulfide, which smells like an unpleasant rotten egg smell. If there is no smell after closing the gas meter valve, it can be concluded that there is a natural gas leakage behind the gas meter valve (such as the gas meter, stove and water heater connection gas hoses between tables, interfaces, etc.).

2.See with your eyes. When the gas is not used at all (turn off the stove and water heater), check whether the last number in the red box of the gas meter moves. If it moves, it can be concluded that there is a natural gas leakage behind the gas meter valve (such as the gas meter, the stove and the water heater are connected to the gas meter hoses, interfaces, etc.).


First, add soap or washing powder to water to make a soap liquid, and apply it to the gas pipe, gas meter hose, cock switch and other places prone to air leakage. When the soap liquid encounters a leak, bubbles will appear in the leaked area. When you see If bubbles appear and continue to grow, it indicates that there is an air leak. Or use a special natural gas detector (such as Combustible Sensor) to check for leaks.

4.For parts that are difficult to apply with soap water and are out of sight, you can touch them with the back of your hands. Generally, you can feel the air leakage with the back of your hands.

After reading the above tips, you can go back and check whether there is a gas leakage problem in your home. If there is a gas leakage problem, you should solve it in time to avoid safety accidents.

How to prevent gas leaks?

At the same time, everyone must prevent gas leaks in daily life, so how to prevent it?

1.Ask professionally qualified personnel to install gas facilities according to specifications to prevent potential safety hazards. Don’t try to install it by yourself because it will leave you with big hidden dangers;

2.When using gas to boil water or cook, be sure to have someone look after you to prevent the soup from overflowing and extinguishing the fire, causing gas leakage;

3.Before going out and going to bed at night, turn off the gas valve in time, develop good gas usage habits, and prevent the gas from being left on and causing gas leakage;

Emergency measures for gas leaks

If a leak occurs, what emergency measures should users take?

1.Cut off the air source first. Immediately turn off the gas appliance switch, the valve in front of the stove, and the valve in front of the gas meter.

2.Do not start electrical appliances and avoid open flames. It is prohibited to touch any indoor electrical switch, because turning on and off any electrical appliance (such as lights, fans, exhaust fans, range hoods, air conditioners, switchboards, wired and wireless phones, doorbells, refrigerators, etc.) may produce tiny sparks, which may lead to explosions.

3.Open doors and windows to allow air to circulate so that gas can dissipate and reduce gas concentration.

4.Evacuate people. Evacuate your family quickly. Neighbor. No one is allowed to approach.

5.Call the police. If there is no gas leakage, such as outdoors, call the gas company’s customer service center.
