I 4 methods to prevent gas leakage

Family gas safety is the top priority for family safety. An gas leakage encounters an open fire, and an explosion is very likely to occur, which will pose a great threat to life and property. Families must use the following “smell, watch, smear, test” 4 methods to prevent gas leakage：

1. Smell

Gas for family is stinked before entering the residents’ homes, so that the gas has a smell similar to stinky eggs, which makes it easy to find leaks. Once you notice a similar odor in your home, it may be a gas leak, which must be checked in time.

2. Watch

In the case of complete exhaust, check whether the numbers in the last red box of the gas table are moving. If it moves, you can be judged to have a leak behind the gas table valve (such as the glue between the gas table, stove and water heater connecting the gas table, interface and other places).

3. Smear

Use soap or laundry powder to make soap liquid, and smear it in sequence to places prone to leakage, such as gas pipes, gas gauge tubes, and tape switches. If soap liquid leaks, it will be blown out of foam by the leaked gas. However, it may not be possible to observe very small leaks, and the test results of professional testing tools shall prevail.

4. Test

Using professional gas detectors (such as household gas detector) to detect gas leaks, you must purchase qualified products from regular channels.

It should be emphasized here that the gas detector is an important safety instrument for detecting gas leaks and an essential safety device for gas use sites. When the gas leaks, the gas detector detects that the concentration of the flammable gas reaches the explosion or the critical point of poisoning, the gas detector will send an alarm signal to remind personnel to take safety measures.

Gas detector can detect various gas concentrations, often used in chemical plants, oil refineries, gas stations, steel mills, households, and other places where gas leaks may occur. The family must install a gas detector (independent gas alarm or a networked gas detector which can work with the alarm system) to make gas safety.

II Gas leakage treatment methods

1. Turn off the main gas valve immediately at home

Once you smell a pungent odor at home and suspect a natural gas leak, you must immediately turn off the main gas valve for natural gas at home to prevent further natural gas leaks. If you are cooking at this time, be sure to turn off the open flame on the stove immediately. If you are taking a shower, the water heater should be turned off to avoid causing a fire. For bottled liquefied gas, it is necessary to turn off the cylinder valve immediately.

2. Quickly open doors and windows for ventilation

Opening doors and windows for ventilation can help dissipate the accumulated gas in the home as soon as possible, reducing the indoor gas concentration.

3. Avoid ignition sources

After suspecting a gas leak, do not turn on or off household appliances such as lights and range hoods, and do not wear or take off chemical fiber clothing or use lighters. These actions may generate static electricity or sparks. The explosion limit of natural gas is 5% -15%, while the explosion limit of liquefied gas is 1.5% -9.5%. Once the explosion limit is reached, it will cause explosion or deflagration when encountering an open flame, which is extremely destructive.

4. Quickly evacuate and call for help

After completing the above steps, personnel should quickly evacuate, transfer to a safe place, and promptly call the gas company’s alarm number for professional personnel to handle.

If you smell a noticeable odor of rotten eggs at home, it indicates that the natural gas leak has accumulated a certain concentration. Please strictly follow the following requirements at this time:

• Immediately turn off the gas valve
• Immediately open doors and windows for ventilation
• Do not open fire
• Do not turn on the lights
• Do not switch on or off any electrical appliances
• Do not answer or make phone calls
• Quickly evacuate to an outdoor safety zone and report to the police

In response to gas leaks, a gas detector should be installed at home. Once a gas leak occurs, the gas detector will be issued in a short period of time. The linkage solenoid valve (or robotic arm), exhaust fan, etc. will be used to cut off the gas source in a timely manner, ventilate and take measures to ensure personal safety.

III 11 tips for daily gas safety use

1. Ensure the safety of gas facilities

The gas pipelines installed in our houses have been strictly constructed and tested, and individuals cannot change the pipelines at will. When renovating a house, if it needs to be renovated, it can only be carried out with the consent of the gas company.

At the same time, the functions of the kitchen should be reasonably laid out. At the position where the pipeline passes, the pipeline cannot be squeezed, hung, corroded or worn, nor can there be heat sources and circuits passing by, and a safe distance must be maintained. A hose connected to a fixed pipeline and gas-fired appliances must have a hoop fix at both ends, and the length cannot exceed 2 meters, the length cannot be increased at will, and the maximum number of years of use is 2 years.

Because of the existence of gas pipelines, the kitchen cannot be transformed into a room for people to live in. This is not only unsafe, but also illegal. We also see gas pipelines that are usually painted yellow outdoors, also to prevent impact or wear.

2. Don’t ignore the installation process

Gas stoves are not available for buying themselves. For example, the gas stove usually needs to be tested for the first time it is bought. The flames are not as large as possible, otherwise they will damage the accessories of the stove, reduce the service life, and even cause accidents. It is best not to commission at will, but it can be debugged by professionals from the gas company, or by professional installers of the gas stove.

3. Choose safe gas appliances

There are many varieties of gas appliances in the market. In addition to the function and appearance, users must also take into account safety when choosing products. High-quality gas stoves will pay more attention to safety in design and materials, and at the same time there will be more protection in installation and after sale. But for non-professionals, users who only buy it once a few years, it is enough to choose products from regular manufacturers and large brands. Although it will be more expensive than those small brands, after all, a penny is paid. The maximum service life of gas gear is 8 years, which must be replaced in time. The products that are used every day are closely related to the safety of our lives and property. This account must be calculated clearly.

4. Pay attention to indoor ventilation when using gas

The room for gas-fired appliances should be kept ventilated outdoors, including gas-fired water heaters and gas stoves. Because when used, if the burning is insufficient, a certain concentration of carbon monoxide (carbon monoxide emissions is standard in the country, and products of unqualified quality will exceed the standard, so qualified gas appliances) must be used. In the room where gas appliances are installed, the windows should not be closed too tightly. When using anti-poisoning, leakage is usually prevented to reach the gas explosion concentration.

When using gas, you must pay attention to ventilation to avoid accidents. If indoor ventilation is poor, the oxygen content in the air will gradually decrease when the gas is burned. Insufficient oxygen supply will cause incomplete combustion, which will easily produce a large amount of carbon monoxide toxic gas and cause poisoning.

5. After the gas is used, remember to close “double valve”

When using gas, someone must take care of it. Every time the gas is used up, the gas stove and the front valve of the stove must be closed. It was found in the household security check that some residents often only closed the gas stove switch after using the gas, but did not close the front valve (gas meter standing valve). Once the glue tube is loose and off, it is easy to cause gas leakage. The consequences are unimaginable.

6. The tape needs to be replaced every two years

Users must regularly replace the gas rubber tube when using gas, and it cannot exceed two years. If the hose is found to be aging, tortoise, hardened, and yellow, it should be replaced in time. The length of the gas glue tube should not exceed 2 meters, and there must be no interface (and no three links). The rubber tube must not be entangled or worn. Especially wet and dark kitchens

Often check whether the glue tube is aging and turtle fractures, especially reminding users to purchase gas-specific rubber tubes for regular manufacturers.

7. Both ends of the hose must be tightened

The gum tube ends with the stove and the gas pipeline at the other end. The connection between the two ends must be tightened. Residents must constantly check whether the hoop is firm, and if there is loosening or falling off, they must be tightened in time to avoid accidents.

8. Use gas stove with flame protection device

It was found in the household security check that some residents are still using stoves without fire protection devices. According to statistics, accidents caused by accidental extinguishing of gas stoves account for more than 30% of indoor gas accidents. And if you use a gas stove equipped with a flame protection device, when the fire is blown out by the wind or by spilled soup, the flame protection device can automatically cut off the gas, effectively prevent accidents, and protect the lives and property of residents. It is recommended that users who do not have a stove protection device still be used. For the safety of you and your family, please replace the natural gas stove with a flame protection device as soon as possible.

9. Do not put flammable and explosive items around the gas

Do not place flammable and explosive items around the gas, such as pesticides, air fresheners, etc., these things have a high temperature, or they will cause an explosion to catch fire when they encounter a fire, and other combustible items should also be kept away from the stove. When using it normally, don’t stay away from the stove for a long time and avoid burning the pot.

10. There is a time limit for the use of gas facilities to be replaced regularly

Natural gas stoves and water heaters have an eight-year service life. There are hidden safety hazards beyond the age limit. Residents are requested to regularly replace the overdue gas equipment to ensure safety and no hidden dangers. In particular, the direct exhaust gas hot water heater has been clearly stipulated to be banned.

11. Regular inspection and maintenance at regular time

Although the staff of the gas company will check the account regularly, they also have to check the connection of the hose frequently to see if there are loose, damaged aging, and pipeline deformation. I also often hear about gas leaks. If anomalies are found, the service hotline of the gas company should be called in time for maintenance. At the same time, a gas detector must be installed at home, which can monitor the gas safety in real time, and some have automatic cut-off functions to protect the gas safety of family life and property.
