How to judge whether the gas leaks?

01

Smell -smell with nose

Generally, the gas supply of the civilian use of gas (ethylene glycol) is treated with gas, so that the gas has a smell of odor -like eggs, so that it is easy to discover leaks. So once you notice similar odors in your home, it may be gas leakage.

02

See -look at the gas meter

In the case of no gas at all, check whether the number in the end red frame of the air meter is moving. For example, if you walk around, you can judge that there will be leaks after the gas meter valve (such as the rubber pipe, interface and other places between the stove and the water heater connecting the air meter).

03

Pick -spray soapy water

The soap or washing powder is adjusted into soap with water, and is applied in order of gas pipes, gas meter gum pipes, rotor switches and other places to leak air to check whether the gas leaks. In the case of gas leak, the soap liquid will be blown out of the foam. When the foam is generated and the number of continuous increase, it indicates that the part has a air leakage. It may not be observed for the extremely small leakage point, and the results of the professional detection tool should be subject to the results.

What should I do if I find gas leakage?

Ventilate immediately

Close the valve and report to the relevant departments in order to find out the cause; timely repair the leaky office to avoid malignant accidents. It should be noted that it is not in a hurry to open the exhaust fan for ventilation, and the exhaust fan is also powered on. Open the window to ventilate immediately.

Don't turn on any electrical appliances

Various electrical switches, plugs, and sockets will produce sparks. The combustible gas leaked indoor leaks will cause explosion after reaching a certain concentration. Therefore, the power should be cut off at the outdoor power gate.

Don't wear and take off your clothes indoors

Putting on and undressing can generate static electricity, especially blended and nylon fabrics, static electricity will also detonate a certain concentration of combustible gas in the air.

Do not use telephones, mobile phones

The inside of the phone and mobile phone may cause a small spark, which can also cause explosion. You should call it after the scene.

What should I do if I find someone gas poisoning?

Once someone is found to be gas poisoning, you should immediately open all the doors and windows of the room, turn off the gas weapon switch, leave the room to breathe out of fresh air or oxygen; the severe person should quickly get out of the poisoning environment with the help Call 120 first aid, breathing heartbeat stop should be performed on the spot and pressed outside the heart. The conditions are allowed to go to hospitals with high -pressure oxygen compartment for rescue treatment.

Pay attention to this when using gas

The family is equipped with liquefied gas cylinders, stoves, pressure reducing valves, gas hoses, etc., and must purchase products that comply with relevant state regulations.

When using gas, someone should take care of it to prevent the soup from spilling the flame or blowing the flame by the wind, causing the gas leak and accidents.

The gas cooker connects the glue tube regularly to check and replace. In winter, the glue pipe is prone to hardening, aging, and cracking. If there is no tube card fixation, it is easy to fall off and cause air leakage. At the same time, the length of the tube should not exceed 2 meters. It is recommended that users use more safer and reliable metal ripples.

When using the liquefied gas cylinder, it should be noted that the cylinder should be used upright and avoids violent shaking. It cannot be exposed to the sun, and items cannot be placed on the cylinder.

If the gas is used for a long time, it is easy to make the indoor oxygen insufficient, and the user should open the doors and windows to ventilate in time. After the use of liquefied gas, the stove switch and liquefied air valve should be turned off in time.

It is necessary to regularly check the rubber pipes and joints of the connection cooker, and it should be replaced immediately when it is found that the aging of the rubber tube should be replaced immediately; the gas appliance that exceeds the period of use should be updated in time.
