General knowledge about safe use of natural gas

1. Common sense of safe use of natural gas

Residents should pay attention to the following points in preventing gas accidents at home: (1) Cooking stoves and water heaters with good use quality and safety performance should be purchased, and fake and shoddy products are the source of accidents; (2) Qualified personnel should be invited to install gas facilities according to the specifications, otherwise it will leave hidden dangers of accidents; (3) It should be used correctly according to the requirements of the product manual, and the gas appliance should be maintained regularly (the water heater is eight to ten months), and it should be repaired in time if it is faulty; (4) When the cooker is used, someone should look after it, and attention should be paid to the ventilation of the use environment. After use, it should be "two closed and one opened", that is, the gas valve and the kitchen door should be closed and the kitchen window should be opened; (5) The gas facilities in the home should be checked frequently, and the aging rubber pipes should be replaced in time, and it is best to use stainless steel corrugated hoses; (6) Install and use the gas leakage alarm device, and invite an obligatory gas safety protector for the whole family.

how to deal with gas leakage? Check whether the switch and gas valve in gas appliance are closed in time; Open the indoor doors and windows to ventilate and let the gas out. If necessary, please call the service hotline of the gas company outdoors immediately; If you find yourself or others suffering from gas poisoning, go outside to breathe fresh air immediately, and if it is serious, you should be sent to the hospital for rescue; Do not turn on any gas appliances, turn on electrical switches (including lights and neighbor's doorbell), use telephones (including mobile phones) indoors, and do not use naked flame to test the source of air leakage.

why do you need to install a gas leak alarm cut-off device at home? Both artificial gas and liquefied petroleum gas have obvious and special odor, and natural gas has obvious odor after odorization. In case of leakage, ordinary people can smell it, but the elderly and children may not react quickly, which may delay the opportunity and cause vicious accidents such as poisoning, fire and explosion, resulting in serious consequences. The flue gas after gas combustion contains toxic carbon monoxide gas, which is colorless and tasteless. This invisible killer victimizes many innocent citizens every year.

GB16914 1997, the national standard "General Rules for Safety Technology of Gas Burning Appliances", stipulates that "the gas leakage alarm cut-off device should be installed in the installation place of gas burning appliances" is a scientific method to prevent gas accidents. Because of the high sensitivity of the gas leakage alarm and cut-off device, it will give an alarm to a small amount of harmful gas quickly, and the gas will be cut off immediately with the cut-off device, thus effectively avoiding all kinds of gas accidents.

The developed countries have become quite popular, so gas accidents rarely occur. Installing a gas leakage alarm cut-off device at home will invite a voluntary gas safety protector for the whole family. How to check the air leakage of gas facilities? When it is suspected that gas pipes and valves are leaking, the following steps can be taken: (1) Turn off all the gas appliances (such as stoves and water heaters), observe the last digit of the gas meter, and there should be no walking phenomenon after long-term careful observation.

(2) Brush the valves, pipes, joints, etc. with soapy water or high-foaming washing powder water. If there is bubbling, there will be air leakage points. (3) Close the air inlet valve in front of the gas meter and ask the maintenance personnel of the natural gas company to repair it.

(4) it is forbidden to use naked flame to check the leakage. Other safety matters When using natural gas, attention should be paid to exhaust and ventilation throughout the year; The gas pipeline shall be exposed, and shall not be buried in the wall or underground, and it is forbidden to cross the bedroom, bathroom and bathroom.

don't seal the gas meter in the cabinet, and keep good ventilation. Places equipped with gas facilities are strictly prohibited as bedrooms; Do not move or disassemble indoor and outdoor gas facilities without authorization.

please install the gas appliance and the flue for discharging waste gas in strict accordance with the instruction manual of gas appliance. And clean and maintain it every year to ensure smooth exhaust emission and safe combustion; Places where gas appliance is used should maintain good ventilation effect, so that the harmful flue gas after combustion can be discharged outdoors in time; Check indoor gas facilities frequently, and report for repair in time if any problems are found.

2. The best tips for gas safety are urgent in eight words

1. Basic characteristics of gas. Natural gas and liquefied gas are flammable and explosive, and the combustion exhaust gas contains toxic gases such as CO.

therefore, the public should pay special attention to the safety of use. Second, the correct installation and use of gas water heaters 1. You should buy a flue-type or forced-discharge water heater, and the water heater should be equipped with a flue to discharge the exhaust gas outdoors to ensure the personal safety of users; 2. The gas water heater should be installed in a well-ventilated room or corridor with few people staying. Living room, bedroom and other rooms cannot be installed. It is strictly forbidden to install the water heater in the bathroom. 3. The gas water heater has a large load and consumes a lot of oxygen. If it is used in a confined space for a long time, it may also cause the user to be in a non-toxic hypoxia coma, so the user should not use the gas water heater for a long time.

4. Ask a professional company to maintain the gas water heater regularly to eliminate potential safety hazards. 5. In-line gas water heater consumes indoor oxygen when burning, and directly discharges exhaust gas into the room after burning, which is very likely to cause gas poisoning.

therefore, the state prohibits the use of direct-row gas water heaters. 6, the use of gas water heaters, do not close the doors and windows, to maintain indoor air circulation, to avoid carbon monoxide poisoning 7, the service life of gas water heaters is generally 6 to 8 years, it is best to replace the water heaters that have exceeded the service life in time to ensure safe use.

Third, gas stoves have gradually become the most common cookware in people's homes. In winter, the time to open windows at home is reduced, so the safety of domestic gas stoves should be paid more attention.

In life, as long as we pay attention to some details when using gas stoves, we can avoid poisoning caused by natural gas leakage. 1, when using, should always pay attention to the color of the fire.

The orange flame indicates incomplete combustion of gas, in which case carbon monoxide will be released. The flame can be adjusted by adjusting the air door under the stove, and the blue flame shall prevail.

2. When cooking soup or boiling water, the container should not be too full, and no one can wait for it, so as to avoid the fire from being doused by spilled soup and water and causing air leakage. 3. The hose should be closely connected with the inlet joint of the gas appliance, and it is best to clamp it with a pipe clamp.

4. It is forbidden to use two kinds of fire sources at the same time in the same room. 5, the family had better prepare dry powder fire extinguishers to be prepared.

6. When stewing or cooking soup, some people like to turn the flame very small, which may easily lead to air leakage or incomplete combustion. Therefore, when the gas stove is in use, the fire should not be too small.

iv. treatment of gas leakage. 1. immediately cut off the gas source and close the valve of gas pipeline and gas appliance; 2, quickly open the doors and windows, let the air circulate, will leak gas out of the room; 3. Call outside for repair and evacuate personnel; 4, male * * * places found gas leakage, immediately call for repair and evacuation; 5. If you find a gas leak in your neighbor's house, you should knock on the door and notify you. Do not use various electrical facilities such as doorbell. 6. When the gas leaks, never turn on the power switch (such as turning on the light or turning off the light), use naked flames, and never use indoor telephones or mobile phones. In particular, it is absolutely forbidden to use the exhaust fan II electric fan to exhaust gas.

5. Precautions for users to use LPG safely. 1. Use it in a separate brick-and-tile kitchen, and properly place LPG equipment. 2, the cylinder must be placed upright, not allowed to lie down or upside down.

3. The cylinder must be kept away from heat sources, and placed in a well-ventilated place where it is easy to move, there is no inflammable substance around, and the distance between the stove and the bottle is 8 cm. It is not allowed to heat the cylinder in any form. ⅲ. Before installing the pressure reducing valve, check the sealing rubber band to ensure that there is no deformation or defect. When installing the pressure reducing valve, the handwheel should be aligned with the valve port, and it should be rotated counterclockwise and tightened. 4. The rubber hose, stove switch, pressure reducing valve and the connection part between handwheel and bottle valve are easy to leak. Please brush the inspection part with soapy water to check the leakage, and do not use fire to check the leakage.

5. It is not allowed to disassemble or refit the special equipment for liquefied petroleum gas without permission. If there is any problem, please refer it to the supplier. 6. When liquefied petroleum gas leaks, close the bottle valve in time, open the doors and windows, and conduct ventilation and evacuation.

In the leakage place, it is forbidden to open all kinds of flames (including cigarette butts), and it is forbidden to turn on and off all kinds of electrical equipment. 7. In case of fire, cut off the gas source (close the bottle valve) as soon as possible, avoid putting the bottle in, and report the fire alarm in time, telephone number: 119.

8. Check frequently, observe carefully and handle problems in time. To ensure safety, please close the cylinder angle valve before going to bed and when going out.

9. It is forbidden to discharge the residual liquid (gas) in the steel cylinder without permission. Sixth, other safe gas use instructions 1. Educate children not to play with the switch of natural gas cookers.

2. Before using gas, you should carefully read the instructions for users of natural gas and master the common sense of maintenance, repair and safety of gas facilities. 3. The hose connecting the cooker should naturally droop under the kitchen surface and keep a distance of 1 cm to avoid being burnt by fire and causing accidents.

always check whether the hose is loose, falling off, cracked or deteriorated. Hose aging should be replaced in time.

4. Users should observe the following regulations: (1) Don't use natural gas pipeline as wire grounding wire. (2) It is forbidden to sleep in kitchens and rooms with natural gas facilities; (3) It is forbidden to buy and pull the hoses at random; The hose shall not exceed 1.5m; (4) Don't pile flammable materials around natural gas cookers, gas meters and water heaters.

(5) It is forbidden to dismantle, install, move or change natural gas pipeline equipment without permission, and it is forbidden to tamper with natural gas meters; (6) Indoor natural gas pipelines and gas meters cannot be wrapped in indoor decoration materials to avoid pipeline corrosion, damage and leakage. 5. After using the gas or not using the gas for a long time (such as going out to visit relatives and travel, etc.), pay attention to turn off the switch of the natural gas stove or water heater to prevent people from going out; At the same time, close the valve in front of the meter to ensure safety.

Basic knowledge of natural gas safety 3. Basic knowledge of natural gas safety? It refers to the high-quality combustible gas generated and transferred by animals and plants under different geological conditions through biological, chemical and geological changes, stored at a certain pressure and buried in strata with different depths.

? Natural gas is a mixture of combustible and nonflammable gases. It is mainly composed of low molecular saturated hydrocarbons and contains a small amount of non-hydrocarbon gases.

in hydrocarbon gas, methane accounts for the vast majority, with little ethane, propane, butane and pentane, and little alkane above heptane. In addition, a small amount of non-hydrocarbon gases generally include carbon dioxide, carbon monoxide, nitrogen, hydrogen, hydrogen sulfide and water vapor, and a small amount of inert gases such as helium and argon.

the calorific value is 39.6MJ/M3, that is, 85 kcal/m3. ? Pure natural gas is mainly composed of methane, which is lighter than air, has a boiling point of -162℃ and is not easy to liquefy.

the explosion limit of natural gas is 5%-15% (volume% in air), and it is relatively easy to explode. ? Natural gas is a clean, high-quality civil and industrial green energy, as well as a raw material for chemical products. At the same time, it is also used as automobile fuel and combined power generation system.

Heat pumps (cooling and heating) and fuel cells have very attractive prospects, and developed countries are competing to develop and apply them. 4 Basic knowledge of natural gas safety Natural gas quality standard (according to the current national standard SY/T514) H2S-2mg/m3 CO2-3. (volume%) high calorific value-﹥31.4mj/m35 Basic knowledge of natural gas safety Gas field gas: combustible gas produced by gas wells, also known as pure natural gas.

the main component is methane, accounting for about 98%. Calorific value

4. Safety knowledge and safety precautions for correct use of natural gas

1. Buy cookers and water heaters with good use quality and safety performance. Fake and shoddy products are the source of accidents;

2. Please ask qualified professionals to install gas facilities according to the specifications. Do not install or change the lines by yourself. Never cover heavy objects on indoor and outdoor gas pipelines.

3. Use it correctly according to the requirements of the product manual. The gas appliance should be maintained regularly (the water heater is from August to October), and it should be repaired in time if there is any fault;

4. When the cooker is in use, someone must look after it, pay attention to the ventilation of the use environment, and achieve "two closed and one opened", that is, close the gas valve and the kitchen door and open the kitchen window; Be sure to turn off the main switch of the air valve when there is no one at home.

5. The gas facilities in the home should be inspected frequently, and the aging and cracked rubber hose should be replaced regularly, and both ends should be fixed to prevent the rubber hose from accidentally falling off and causing accidents. At present, a metal gas connecting pipe with a service life of fifteen years is gradually replacing the previous rubber hose.

6. install and use the gas leakage alarm device, and give an alarm in time in case of leakage to ensure home safety.
