1. In case of accidental gas leakage, do not start any electrical equipment, including turning on lights, exhaust fans, range hoods, televisions, radios, making phone calls, etc. , and open the doors and windows for ventilation in time, and report to the gas company in time.
2. gas appliance should choose qualified products from regular manufacturers, and should not bury hidden dangers of accidents just because it is cheap for a while. 3. When installing the gas water heater, you must ask a professional team for standardized installation. When using the water heater, we must keep the room well ventilated.
When using gas, someone must watch the stove. Check whether the gas valve is closed before going out and going to bed every day.
5. During interior decoration, gas facilities shall not be moved, gas meters and pipes shall not be installed in cabinets, and gas valves shall not be sealed. 6. The gas stove can't be placed directly under the gas meter, and it must be staggered more than 30 cm below the gas meter, so that the gas meter can't be heated and damp.
2. Gas safety knowledge
Matters needing attention in gas use
1. After using gas, be sure to turn off the stove switch and gas pipeline valve at the same time;
2. Always check whether the hose joint is fixed with clips and whether the hose is aging and cracked;
3. When the smell is found, open the doors and windows immediately and call the gas company to report the leakage in time;
4. Long-term use of gas must be ventilated;
5. Please read the gas safety propaganda content on the back of the gas purchase invoice carefully;
6. gas appliance meeting national standards must be used, and infrared cookers are strictly prohibited.
Extended data:
In addition to the kitchen gas leakage, the bathroom is also a frequent area of gas poisoning, especially in winter. Most of these gas poisoning incidents occurred in rental houses. Because the gas water heater is installed in the home and there is no ventilation device, when the weather is cold, the doors and windows are closed, which makes the gas burn insufficiently, resulting in a large amount of carbon monoxide and poisoning.
Experts advise not to close the doors and windows when taking a bath with a gas water heater. Hypoxia is very harmful to people. Brain hypoxia will lead to irreversible necrosis of brain cells, dementia, slow response and other sequelae, and even serious poisoning death.

3. 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.
4. Gas prevention tips
Avoid open flames, cell phones, battery waves, etc. The best way to prevent gout in windows is to install a pipe in the window, cover the stove at night and turn on the flue switch.
Gas poisoning at home mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas and natural gas poisoning. The former is more common in winter when coal stoves are used for heating, doors and windows are closed and smoke is not good, while the latter is more common in liquefied gas stoves or gas pipelines leaking. When gas poisoning occurs, patients will initially feel headache, dizziness, nausea, vomiting and weakness. When he realizes poisoning, he often struggles to get out of bed and open the door and open the window, but usually only a few people can open the door. Most patients have convulsions and coma quickly, and their cheeks, chest skin and lips are cherry red. If not treated in time, they will soon die of respiratory depression.
Gas poisoning is often divided into three types according to the concentration of carbon monoxide contained in inhaled air and the length of poisoning time: (1) light: the poisoning time is short, and the carboxyhemoglobin in blood is 10%-20%. It manifests as early symptoms of poisoning, such as headache, dizziness, palpitation, nausea, vomiting, limb weakness, and even fainting for a short time. Generally, the mind is still clear. Inhale fresh air, and after leaving the poisoned environment, the symptoms will soon disappear, generally leaving no sequelae.
(2) Medium-sized: the poisoning time is a little longer, and carboxyhemoglobin accounts for 30%-40% in the blood. On the basis of mild symptoms, collapse or coma may occur. The skin and mucous membrane show cherry red peculiar to gas poisoning.
If the rescue is timely, you can wake up quickly and fully recover within a few days. There are generally no sequelae. (3) Heavy-duty: it is found too late, too much gas is inhaled, or high concentration of carbon monoxide is inhaled in a short time, and the blood carboxyhemoglobin concentration is often above 50%. The patient is in a deep coma, with various reflexes disappearing, incontinence, cold limbs, decreased blood pressure, shortness of breath and imminent death.
Generally, the longer the coma, the more serious the prognosis, and the sequelae such as dementia, decreased memory and understanding, and limb paralysis often appear. In case of gas poisoning at home, the main measures are as follows: (1) Open the doors and windows immediately, move the patient to a place with good ventilation and fresh air, and keep warm.
Find out the causes of gas leakage and eliminate hidden dangers. (2) Loosen the button, keep the respiratory tract unobstructed, and remove the mouth and nose secretions. If respiratory arrest is found, mouth-to-mouth artificial respiration should be performed immediately, and the heart should be performed outside the body.
(3) Acupuncture treatment should be carried out immediately, and the acupoints are Taiyang, Lieque, Renzhong, Shaoshang, Xuan Shi, Hegu, Yongquan and Zusanli. Patients with mild or moderate poisoning can gradually wake up after acupuncture.
(4) Give oxygen immediately, and if possible, immediately transfer to the hospital hyperbaric oxygen chamber for hyperbaric oxygen treatment, especially for patients with moderate and severe gas poisoning, which can not only awaken patients, but also reduce sequelae. (5) Immediately inject 50 ml of 50% glucose solution intravenously, and add vitamin C 500- 1000 mg.
Light and moderate patients can use it for 2 days, 1-2 times a day, which can not only replenish energy, but also dehydrate. Early application can prevent or alleviate brain edema. (6) Coma patients should be treated as coma patients.
(7) Treatment after gas poisoning is corrected: ① Insist on taking a deep breath, chest-expanding exercise and Tai Ji Chuan for about 30 minutes in the park or balcony every morning, and light and medium-sized poisoners should do morning exercises for 7- 14 days continuously; Patients with severe poisoning can do morning exercises for 3-6 months according to sequelae, and do five-bird play, patch shirts, eight-segment brocade and so on. ② Continue to take gemcitabine 1-2 tablets daily for 7- 14 days, or take vitamin C 0. 1-0.2g three times a day, or take vitamin B 1, B6, vitamin B complex, etc.
(3) Check the gas usage to prevent poisoning again; A. Check whether there is air leakage, whether the installation is reasonable, whether the gas stove is trouble-free and whether the use method is correct; B. Whether the heating mode in winter is correct, whether the gas pipeline is unblocked and whether the indoor ventilation is good; Try not to use a coal stove for heating. If there is, you must abide by the rules of coal stove heating, and don't be careless; D the water heater should be built in a room separate from the bath, and the connecting pipes between the gas and the water heater should be checked regularly; E. If you feel the smell of gas after entering the room, you should quickly open the doors and windows and check whether there is gas leakage or coal stove in the room. Do not ignite; F. Wipe the cooker frequently to ensure that it will not cause human pollution. After using the gas switch, wash your hands with soap and rinse with tap water. Install an exhaust fan or range hood in the kitchen; G. Be sure to use special rubber hoses for gas, not nylon, vinyl pipes or worn pipes, and check the pipeline access once every six months.

6. What are the common sense of home appliance gas safety?
Install a gas leak alarm, because ordinary natural gas is colorless and tasteless, unlike gas. If the gas leaks, it will be difficult for everyone to detect it.
1. Everyone should use the alarm to monitor whether there is any leakage of natural gas at home, so as to avoid disasters.
2. Natural gas equipment is not allowed in the bedroom. When installing gas equipment, the room should also be ventilated.
3. The gas pipeline should not be concealed, otherwise it is not conducive to maintenance. When the natural gas is used up, not only the furnace or heating switch should be turned off, but also the main valve of natural gas should be turned off to avoid gas leakage.
4. Flammable articles should not be piled up near natural gas, and related open flames are also prohibited.
Before going out to sleep, you should also check whether the gas valve is closed tightly. You can open some windows to keep good air circulation. If you are going out for a long time, it is also recommended to leave a set of home keys for relatives or trustworthy people. In the event of fire and other related problems, it is also convenient for firefighters to enter the room as soon as possible to put out the fire.
It is also necessary to regularly check some key parts such as rubber pipes and valve ports. For example, you can use soapy water to see if there is a leak (like the inner tube of some bicycles in the past). If we find some safety hazards in time, such as aging rubber pipes and tight valves.
7. If the natural gas equipment fails, it shall not be disassembled or repaired without permission. At this time, you can call the gas company to repair the fault, or you can ask some professionals to come to the door for repair.
7. Common sense of safe use of natural gas
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.
8. What are the common safety knowledge of gas stoves?
Safety knowledge of gas cookers first, make sure that the gas source used at home is the same as the gas source you buy, otherwise it will not be used.
Second, in order to ensure the safe use of the cooker, we must buy quality-guaranteed pressure reducing valves and gas pipes produced by regular manufacturers. Third, users who use pipeline gas and natural gas must buy products produced by large domestic professional manufacturers to ensure their safety performance and thermal efficiency in good condition.
Fourth, when the cooker is burning vigorously, everyone should adjust the damper under the cooker, which can adjust the mixing ratio of air and gas. Don't panic once the cooker leaks. At this time, you can't turn on the range hood, let alone light the cooker. Instead, you should open the doors and windows to ventilate and let the gas dissipate automatically.
