To prevent gas accidents in residents' homes, we should pay attention to the following points: (1) buy stoves and water heaters with good quality and safety, and fake and shoddy products are the source of accidents; (2) Please ask qualified personnel 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 (water heater once every eight to ten months) should be maintained regularly, and it should be repaired in time if there is any fault; (4) When the cooker is used, someone should take care of it and pay attention to the ventilation of the use environment. After use, it should be "two closed and one opened", that is, close the gas valve and kitchen door and open the kitchen window; (5) The gas facilities in the home should be inspected frequently, and the aging rubber pipes should be replaced in time. It is best to use stainless steel corrugated hoses; (6) Installation and use of gas leakage alarm devices, and provision of compulsory gas safety protectors for the whole family.
How to deal with gas leakage? Check whether the switches and gas valves 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 outdoor gas company 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 appliance, do not turn on electrical switches (including lights and neighbors' doorbell), do not use telephones (including mobile phones) indoors, and do not use naked flame to test the air leakage source.
Why do you want to install a gas leak alarm cut-off device at home? Both artificial gas and liquefied petroleum gas have obvious special smells, and the smell of natural gas is obvious after odorization. Once a leak occurs, most people can smell it, but the elderly and children may not respond 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 hurts many innocent citizens every year.
The national standard "General Technical Rules for Safety of Gas Burning Appliances" (GB169141997) stipulates that "gas leakage alarm and cut-off devices 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 cut-off device, it can quickly alarm a small amount of harmful gas and cut off the gas immediately through the cut-off device, effectively avoiding all kinds of gas accidents.
Developed countries have become quite popular, so gas accidents rarely occur. Installing a gas leak alarm cut-off device at home will invite a voluntary gas safety protector for the whole family. How to check the gas leakage of gas facilities? When gas pipes and valves are suspected to be leaking, the following steps can be taken: (1) Turn off all gas appliance (such as cookers and water heaters), observe the last digit of the gas meter, and there should be no movement after long-term careful observation.
(2) Brush valves, pipes, joints, etc. Use soapy water or high foam washing powder water. If there is a bubble, there will be a leak. (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 open flame to leak. When using natural gas for other safety matters, pay attention 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 cupboard, keep good ventilation. Places with gas facilities are strictly prohibited as bedrooms; Do not move or dismantle indoor and outdoor gas facilities without authorization.
Please install gas appliance and exhaust flue in strict accordance with gas appliance's instructions. And clean and maintain it every year to ensure smooth exhaust emission and safe combustion; The place where gas appliance is used should maintain good ventilation effect, so that the harmful smoke after combustion can be discharged outdoors in time; Check indoor gas facilities frequently, and report for repair in time when problems are found.
2. Gas safety tips are best in eight words.
First, the basic characteristics of natural gas and liquefied gas are flammable and explosive, and the combustion waste 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 heater 1, should buy flue or forced exhaust water heater, water heater should be installed with flue, so as to discharge waste gas outdoors and ensure the personal safety of users; 2. Gas water heaters should be installed in rooms or corridors with good ventilation and few people. Living room, bedroom and other rooms cannot be installed. It is forbidden to install a water heater in the bathroom. 3. The gas water heater has heavy load and large oxygen consumption. If it is used in a confined space for a long time, it may also cause the user to be in a non-toxic and oxygen-deficient coma, so the user should not use the gas water heater for a long time.
4. Regularly ask a professional company to maintain the gas water heater 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 in-line gas water heaters. 6. Use gas water heaters, don't close doors and windows, keep indoor air circulation, and avoid carbon monoxide poisoning. 7. The service life of gas water heaters is generally 6 to 8 years. It is best to replace water heaters that have exceeded their 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 for opening windows at home is reduced, and the safety of domestic gas stoves should be paid more attention to.
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, always pay attention to the color of fire when using.
An orange flame indicates incomplete combustion of gas, in which case carbon monoxide will be released. The flame can be adjusted by adjusting the lower air door of 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 should wait, so as to avoid the fire being doused by the spilled soup and causing air leakage. 3. The hose should be closely connected with the air inlet joint of gas appliance, and it is best to clamp it with a pipe clamp.
4, in the same room, it is forbidden to use two kinds of open flame at the same time. 5. It is best for families to prepare dry powder fire extinguishers for emergencies.
6. When stewing or cooking soup, some people like to adjust the flame very small, which may easily lead to air leakage or incomplete combustion. Therefore, when the gas stove is used, the fire should not be too small.
Four. Treatment of gas leakage 1. Immediately cut off the gas source and close the gas pipeline and the valve of gas appliance; 2, quickly open the doors and windows, let the air circulate, will leak gas out of the room; 3. Call outside for maintenance and evacuate personnel; 4, male * * * places found gas leakage, immediately call for emergency repair and evacuation; If you find a gas leak in your neighbor's house, knock on the door to inform you. Don't use all kinds of 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), do not use naked flame, and do not use the indoor telephone or mobile phone. In particular, it is absolutely forbidden to use the second generation electric fan of exhaust fan to exhaust exhaust exhaust gas.

Instructions for users of natural gas In order to ensure the smooth installation of natural gas and the safe use of natural gas by users, our company puts forward the following requirements for users in view of the common mistakes made by some users in using natural gas: 1. Users must widely publicize the "User Instructions" to users in their own units or areas, so that all users can understand this "User Instructions" and follow it.
2. Without the permission of the supplier, the gas pipeline shall not be added, dismantled or modified, and the gas supply facilities shall not be changed or damaged. If the gas supply facilities are damaged, or the pressure test must be re-tested because of the removal of the gas pipeline, the relevant construction costs must be borne by the user.
3. The gas metering device shall not be replaced or changed without authorization, and the gas pipeline and gas meter shall not be wrapped during decoration. Otherwise, normal gas supply can only be carried out after removing all obstacles that hinder safe gas supply. Four, according to state regulations, users who use natural gas are not allowed to use the second fire source in the same space.
The user's gas place must be spacious and well ventilated. If the conditions are not up to standard, the conditions for safe gas use shall be created according to the requirements of suppliers. Otherwise, the supplier will stop gas supply until the safety conditions are met. 5. Users who stop using gas or change the use of gas or expand the scope of gas use shall apply to the supplier for relevant procedures, and the supplier will be held accountable according to relevant laws and regulations.
Publicity Sheet for Safe Use of Natural Gas Natural gas has been accepted by the general public because of its advantages of convenience, cleanliness, economy, energy saving and environmental protection, and the number of users is increasing day by day. However, many users lack the knowledge of safe use of natural gas and the experience of emergency treatment in case of accidents. In order to reduce and avoid the occurrence of user safety accidents, the nature and safe use of natural gas are publicized to the public in the form of questions and answers. Please follow this operation strictly.
1. What are the components and properties of natural gas? A: Composition: The main component is methane (more than 95%), and a small amount of hydrogen sulfide and water vapor. Properties: colorless and transparent, lighter than air, flammable and explosive, etc.
It is particularly important to note that natural gas belongs to Class A flammable and explosive gas, with an explosion limit of 5.3%- 1.5% and a minimum ignition energy of 0.28 mJ. 2. Does natural gas smell? What is that smell? Why? Answer: Natural gas itself is colorless and odorless, but in order to prevent leakage and facilitate users to smell it, odorizing agent is specially added in the process of natural gas transmission and distribution.
3. What gas will be produced by natural gas combustion? Under what conditions? How to use it safely? A: Under the condition of air circulation, methane burns to produce carbon dioxide and water. Although a small amount of sulfur dioxide is produced, the combustion of hydrogen sulfide produces sulfur dioxide and water, which will not cause any harm to human body. In a closed space without air circulation, methane combustion will produce carbon monoxide due to lack of oxygen, which will cause death.
Proper use, when using gas appliance, the place where it is located must keep air circulation. (1 m3 natural gas (purity calculated by 100%) needs about 2.0 m3 oxygen and about 10 m3 air to burn completely. 4. What about natural gas leakage? Answer: In case of natural gas leakage, all indoor valves should be closed, doors and windows should be opened, indoor air circulation should be maintained, and the gas company should be reported immediately (Tel:).
Don't use any gas appliance at this time, don't switch the power supply, and don't bring any Mars to prevent objects from colliding and sparking. 5. What if there is natural gas poisoning? Answer: For mild patients (runny nose, tears, dizziness, brain swelling, etc.). ), just move the patient outdoors to breathe fresh air and recover in a short time.
Severe cases (numbness of limbs, vomiting, coma, unconsciousness, foaming at the mouth, etc.). ) should be sent to the hospital for emergency treatment, be sure to explain to the doctor that it is natural gas poisoning. 6. What if the natural gas catches fire? Answer: If possible, close all valves and report to the gas company and "1 19" as soon as possible.
Don't panic, explain that the fire was caused by natural gas, and explain the detailed location and contact number of the fire. 7. What are the requirements for using gas? Answer: No one is required to stay when using. If the gas stops during use (mostly due to facility failure), you should close the valve of gas appliance and call the gas company. Never make a phone call without closing the valve.
8. What should the natural gas company pay attention to when notifying to stop gas? Answer: The valve should be closed when the gas is stopped. Do not open the valve until ventilation is restored. If there is no gas when the gas supply is resumed, you should contact the natural gas company by telephone.
9. What should the market pay attention to when purchasing gas stoves, wall-hung boilers, water heaters and other products? Answer: The purchase of gas stoves, wall-hung boilers, water heaters and other commodities must be produced by manufacturers with production licenses, product certificates, safety instructions and obvious warning signs. The gas appliances used must be tested by the testing center designated by the local gas administrative department; After being registered by the safety supervision department designated by the local administrative department, it can be sold and used.
Prevent fake and shoddy products from endangering the safety of citizens' lives and property. 1 1. After installation, how do users manage indoor and outdoor gas supply facilities? How to apply for ventilation? Answer: After installation, all valves are closed and must not be opened! If you need gas, please ask the natural gas company to ventilate and debug you, and explain how to use natural gas facilities, gas appliance and related matters needing attention correctly. Please sign the safety disclosure form when you are familiar with the explanation.
12. Can a second fire source be used near gas appliance? No second fire source is allowed near gas appliance. Such as electric furnace, liquefied petroleum gas furnace, coal furnace, etc. , so as not to cause a fire accident.
13. Why can't people live in places with natural gas facilities? What should I pay attention to? In kitchens and places equipped with natural gas pipelines, gas meters, stoves and other equipment, sundries, inflammable and explosive articles and open flames are not allowed to be piled up. It is forbidden to live as a bedroom.
Because, once natural gas pipelines, gas meters, stoves and other equipment are damaged and leaked, it is easy to cause fire or poisoning and other dangers. 14. How to check air leakage? Users should always pay attention to check whether natural gas pipelines and equipment are leaking. When checking, soapy water can be applied to places where air leakage may occur, such as the joints of pipes, instruments, stove switches, etc. If there is air leakage, bubbles will be blown up there.
It is forbidden to check the leakage with open flame. Natural gas companies regularly strengthen public inspections, and full-time inspectors equipped by the company enter users' homes.
7. Some practical common sense of safe gas use?
Seven preventive measures for gas safety:
First, pay attention to indoor ventilation when using gas.
Entering winter is also the season with frequent gas accidents. Residents should use gas while closing doors and windows for heating, but they must pay attention to ventilation to avoid accidents. If the indoor ventilation is poor, the oxygen content in the air will gradually decrease when the gas is burned, and insufficient oxygen supply will lead to incomplete combustion, which will easily produce a large amount of toxic carbon monoxide gas and cause personnel poisoning.
Second, remember to close the "double valve" after using gas.
When using gas, someone must take care of it, and the gas stove and the valve in front of the stove must be turned off every time the gas is used up. It is found in the household security inspection that some residents often only turn off the switch of the gas stove after using up the gas, but not the valve in front of the stove (the riser valve of the gas meter). Once the hose is loose and falls off, it will easily lead to gas leakage, and the consequences will be unimaginable.
Third, the hose needs to be replaced every two years.
Users should change the gas hose regularly when using gas, and the longest time should not exceed two years. If the hose is found to be aging, cracked, hard and yellow, it should be replaced in time. The length of gas transmission hose shall not exceed 2m, and there shall be no interface (no tee). Hoses must not be wound or penetrated through walls. Especially in the damp and dark kitchen.
Always check whether the rubber hose is aging and cracked, and especially remind users to buy gas-specific rubber hoses from regular manufacturers.
Four, the pipe clamps at both ends of the hose must be tightened.
One end of the gas hose is connected to the cooker, and the other end is connected to the gas pipeline. The joints at these two ends should be tightened with pipe clamps. Residents must always check whether the pipe clamp is firm, and tighten it in time if it is loose or falls off, so as to avoid accidents.
8. Safety knowledge and safety matters that should be paid attention to when using natural gas correctly.
1. Buy high-quality and safe cookers and water heaters. Fake and shoddy products are the source of the accident; 2. Please ask qualified professionals to install gas facilities according to the specifications. Do not install or change the wiring yourself. Do not cover heavy objects on indoor and outdoor gas pipelines. 3. Use it correctly according to the requirements of the product manual. Gas appliance should be maintained regularly (the water heater is 65438+ 10 in August-June), and it should be repaired in time if there is any fault; 4. When the cooker is used, someone must take care of it, pay attention to the ventilation of the use environment, and achieve "two closes and one opens", 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 no one is at home.
5. The gas facilities in the home should be checked frequently, and the aging and cracked hoses should be replaced regularly, and both ends should be fixed to prevent accidents caused by accidental shedding of hoses. At present, the metal gas connecting pipe with a service life of fifteen years is gradually replacing the previous rubber hose.
6. Install and use gas leakage alarm device, and give an alarm in time in case of leakage to ensure home safety.
9. Common sense of safe use of natural gas
How to use gas safely? People usually refer to combustible gases such as natural gas, liquefied petroleum gas and coal gas as gases.
Gas brings a lot of convenience to people's lives, but if it is used improperly, it will also cause disaster. Pay attention to the following points when using gas: 1. Read the operating instructions of gas appliances carefully and operate and use them in strict accordance with the requirements of the instructions.
2. When using a manually ignited gas stove, we should adhere to the principle of "fire equals gas", that is, put the fire source close to the cooker first, and then open the gas valve. 3. Always keep gas appliance in good condition, and repair it in time if it leaks; If there is air leakage during use, the main valve should be closed immediately and the air source should be cut off.
4. When gas appliance is in working condition, people can't leave for a long time, so as to avoid the fire being blown out by the wind or doused by the overflowing water in the pot, resulting in a large amount of gas leakage and fire. 5. Use gas appliances (such as gas stoves and gas water heaters). ), should fully ensure indoor ventilation, keep enough oxygen to prevent gas poisoning.
10. Gas safety knowledge
Please read the instructions carefully before using gas appliance and operate correctly as required.
2, the use of gas equipment room must be kept well ventilated. 3. Regularly check whether the indoor gas pipeline leaks. The inspection method is to brush the pipe joint with soapy water. If bubbles appear, or observe whether the red mantissa of the gas meter rotates. If the red mantissa changes, it proves that there is air leakage. You need to call Zhongtian customer service at 7545687 for maintenance.
4. Check whether the pipe clamp is installed on the connecting hose of the cooker. If aging wear is found, replace it immediately. 5. When finding air leakage, don't switch on the power switches such as exhaust fan and range hood, don't make phone calls or answer the phone at the scene, immediately open the doors and windows for ventilation, call 7545687 for repair after leaving the scene in time, and wait for the maintenance personnel to come to the door for treatment.
6. When using the gas stove, remember to "keep people away from the fire" to prevent the fire from being extinguished by spilled soup or wind, resulting in air leakage. 7. If the gas water heater and cooker fail, it is necessary to ask professionals to repair them immediately.
8. It is forbidden to install gas water heaters in toilets. 9. Do not use other fire sources in the room where gas equipment is installed.
10, if you go out for a long time, remember to close the valve in front of the watch. 1 1. Do not place inflammable and explosive articles around the gas stove.
12. Rooms with gas facilities and pipelines are forbidden to live in. 13. Don't use the gas water heater for a long time at a time (15 minutes).
14, educate children not to tamper with the switch of burning appliances and not to light the stove to prevent accidents. 15. When using gas appliance, don't do anything else until the combustion is normal. After use, please check whether the switch of the cooker and the valve in front of the cooker are closed.
16. Units and individuals using pipeline gas facilities shall not dismantle, modify, relocate or install gas facilities and appliances without authorization. If it is necessary to install, dismantle, modify and relocate the gas pipeline, it must be carried out by professional construction personnel of China Natural Gas Company. Otherwise, due to potential violations, natural gas will not be transported. Users can call 7545687 or go to Tianyuan District Business Office to handle business. 17. When decorating a house, users should not turn off gas facilities in a confined space. If gas facilities must be hidden, they must ensure that the hidden facilities have a certain ventilation hole area.
