Precautions for using gas

1. After using gas, be sure to turn off the stove switch and gas pipe valve at the same time;

2. Frequently check whether the hose connections are fixed with clips and whether the hoses are aged or cracked;

3. If you find any odor, immediately open the doors and windows and call the gas company to report the leak;

4. Ventilation is required when using gas for a long time;

5. Please carefully read the gas safety promotion content on the back of the gas purchase invoice;

6. Be sure to use For gas appliances that comply with national standards, the use of infrared stoves is strictly prohibited.

Extended information:

In addition to kitchen gas leaks, bathrooms are also areas where gas poisoning incidents often occur, especially in winter. Most of these gas poisoning incidents occur in rental houses. Because the gas water heater is installed in the house and there is no ventilation device, when the weather is cold, the doors and windows are closed tightly, resulting in insufficient combustion of the gas, thus producing a large amount of carbon monoxide, leading to poisoning.

Experts recommend that you do not close the doors and windows when taking a bath with a gas water heater. Hypoxia is very harmful to people. Hypoxia in the brain will cause irreversible necrosis of brain cells, resulting in sequelae such as dementia and unresponsiveness. Serious Even poisoned to death.

3. Several practical common sense for safe use of gas

Seven principles of gas safety Important notes:

1. Pay attention to indoor ventilation when using gas

Winter is also the season when gas accidents occur frequently. The majority of residents use gas-fired heaters while closing doors and windows to keep warm. However, 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. Insufficient oxygen supply will lead to incomplete combustion, which will easily produce a large amount of carbon monoxide toxic gas, causing personnel poisoning.

2. Remember to close the "double valve" after using gas

When using gas, someone must supervise it. After each use of gas, be sure to close the gas stove and the valve in front of the stove. . During the home security inspection, it was found that after using up the gas, some residents often only turned off the switch of the gas stove, but did not turn off the valve in front of the stove (the gas meter riser valve). Once the hose becomes loose or falls off, it is easy to cause gas leakage, with disastrous consequences.

3. The hose needs to be replaced every two years

Users must replace the gas hose regularly when using gas. It should not exceed two years. If the hose is found to be aging, cracked or hardened, , Yellowing phenomenon should be replaced in time. The length of the gas hose should not exceed 2 meters, and there must be no interface (no tee). The hose must not be entangled or penetrate the wall. Especially in humid and dark kitchens, it is more important to check the hoses frequently to see if they are aged or cracked. Users are particularly reminded to purchase gas-specific hoses from regular manufacturers.

4. The pipe clamps at both ends of the hose must be tightened

One end of the gas hose is connected to the stove, and the other end is connected to the gas pipe. The connection between the two ends must be tightened with pipe clamps. Residents must always check whether the pipe clamps are firm and tighten them in time if they are loose or falling off to avoid accidents.

4. Tips on preventing gas

Avoid open flames, mobile phones, battery waves, etc. The best way to prevent gout is to install a pipe on the window and keep the stove on at night. To cover it, the flue switch must be turned on.

Gas poisoning in the home mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas, and natural gas poisoning. The former is more common in coal stoves for heating in winter, doors and windows are closed, and smoke exhaust is poor. The latter is more common in liquefied stoves. Leakage or gas pipe leakage, etc. When gas poisoning occurs, the patient initially feels headache, dizziness, nausea, vomiting, and weakness. When he realizes that he has been poisoned, he often struggles to get out of bed and open the door or window. However, generally only a few people can open the door, and most patients develop symptoms quickly. Convulsions, coma, and the skin of the cheeks, chest, and lips turn cherry red. If treatment is not received in time, respiratory depression may result in death.

Gas poisoning is usually divided into three types according to the concentration of carbon monoxide contained in the inhaled air and the length of poisoning time: (1) Mild: the poisoning time is short, and the carboxyhemoglobin in the blood is 10%--20 %. It manifests as early symptoms of poisoning, including headache, dizziness, palpitations, nausea, vomiting, limb weakness, and even brief fainting. Generally, the symptoms disappear quickly after inhaling fresh air and leaving no sequelae.

(2) Medium type: The poisoning time is slightly 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 membranes appear the cherry red color characteristic of gas poisoning.

If the rescue is timely, the person can wake up quickly and fully recover within a few days, usually without any sequelae. (3) Severe disease: found too late, inhaled too much gas, or inhaled high concentrations of carbon monoxide in a short period of time. The blood carboxyhemoglobin concentration is often above 50%. The patient appears in deep coma, various reflexes disappear, and is incontinent. , cold limbs, decreased blood pressure, shortness of breath, and death soon.

Generally, the longer the coma lasts, the more serious the prognosis is, often leaving sequelae such as dementia, reduced memory and understanding, and limb paralysis. If gas poisoning occurs in a family, the main measures are: (1) Open doors and windows immediately, move the patient to a well-ventilated place with fresh air, and keep warm.

Find the cause of gas leakage and eliminate hidden dangers. (2) Loosen clothes buttons, keep the respiratory tract open, and remove secretions from the mouth and nose. If respiratory arrest is found, mouth-to-mouth artificial respiration should be performed immediately, and extracorporeal cardiac arrest should be performed.

(3) Immediately perform acupuncture treatment, selecting acupoints such as Taiyang, Lieque, Renzhong, Shaoshang, Shixuan, Hegu, Yongquan, Zusanli, etc. Those with mild or moderate poisoning can gradually wake up after acupuncture.

(4) Give oxygen immediately. If possible, you should immediately transfer to the hospital’s hyperbaric oxygen chamber for hyperbaric oxygen therapy. This is especially suitable for patients with moderate and severe gas poisoning. It can not only revive the patient, but also reduce the sequelae. . (5) Immediately intravenously inject 50 ml of 50% glucose solution and add 500-1000 mg of vitamin C.

Mild and medium-sized patients can use it for 2 days, 1-2 times a day. It not only can replenish energy, but also has the effect of dehydration. Early application can prevent or reduce cerebral edema. (6) Comatose patients should be treated as comatose patients.

(7) Treatment after gas poisoning is corrected: ① Insist on going to the park or doing deep breathing exercises, chest expansion exercises, and Tai Chi on the balcony in the morning for about 30 minutes a day. People with mild or medium poisoning should do morning exercises for 7- -14 days; patients with severe poisoning can continue morning exercises for 3 to 6 months according to the sequelae, such as Wu Qin Xi, Tiebushi Gong, Baduanjin, etc. ②Continue to take 1-2 pills of Jinvita every day for 7-14 days, or 0.1-0.2 grams of vitamin C 3 times a day. You can also take appropriate amounts of vitamins B1, B6, vitamin B complex, etc.

③ Check the gas usage to prevent re-poisoning; a. Check whether there is any gas leakage, whether the installation is reasonable, whether the gas stove is faulty, whether the usage method is correct, etc.; b. whether the heating method in winter is correct, Check whether the gas pipeline is smooth and indoor ventilation is good; c. Try not to use coal stoves for heating. If you use coal stoves, you must abide by the coal stove heating rules and do not be careless; d. The water heater should be built in a separate room from the bath, and the gas and water heater should be checked frequently The connecting pipelines are intact; 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 a coal stove in the room. Do not light a fire; f. Wipe the stove frequently to ensure that the stove does not cause human body pollution. After using the gas switch, wash hands with soap and water. Install an exhaust fan or range hood in the kitchen; g. Be sure to use special rubber hoses for gas. Do not use nylon, vinyl or worn-out pipes. Check the pipeline access every six months.

It manifests as early symptoms of poisoning, including headache, dizziness, palpitations, nausea, vomiting, limb weakness, and even brief fainting. Generally, the symptoms disappear quickly after inhaling fresh air and leaving the poisoning environment. There are generally no sequelae. (2) Medium type: The poisoning time is slightly longer, and carboxyhemoglobin accounts for 30% to 40% in the blood. On the basis of mild symptoms, collapse or coma may occur.

The skin and mucous membranes show the cherry red color unique to gas poisoning. If rescued in time, people can wake up quickly and fully recover within a few days, usually without any sequelae.

(3) Severe: The patient is discovered too late, inhales too much gas, or inhales high concentrations of carbon monoxide in a short period of time. The blood carboxyhemoglobin concentration is often above 50%, and the patient appears in deep coma. This reflex disappears, urinary and fecal incontinence, cold limbs, blood pressure drops, shortness of breath, and death will occur quickly. Generally, the longer the coma lasts, the more serious the prognosis is, often leaving sequelae such as dementia, reduced memory and understanding, and limb paralysis.

6. What are the common sense about gas safety in household appliances?

Install a gas leak alarm, because general natural gas is colorless and odorless, unlike coal gas. Once a natural gas leak occurs, it will be difficult for everyone to detect it.

1. Everyone should use alarms to monitor whether there is a leak of natural gas at home, so as to avoid disasters.

2. Natural gas equipment cannot be placed in the bedroom. When installing gas equipment, the room should also be ventilated.

3. Gas pipelines cannot be hidden, otherwise it will be difficult to maintain. After using the natural gas, you should not only turn off the stove or heating switch, but also close the main valve of the natural gas to avoid gas leakage.

4. Inflammable items cannot be piled near natural gas, and related open flames are also prohibited.

5. Before going out or going to bed, you should also check whether the gas valve is closed tightly. You can open some windows to maintain good air circulation. If you are going out for a long time, it is also recommended to leave a set of home keys with relatives or trustworthy people. Once a fire or other related problems occur, it will also be convenient for firefighters to enter the house as soon as possible to put out the fire.

60 also needs to regularly conduct some simple inspections on some key locations such as rubber pipes and valve openings. For example, you can use soapy water to see if there are air leaks (like some previous repairs). (like bicycle inner tubes), if discovered in time, there may be some safety hazards such as aging rubber tubes and loose valves.

7. If there is a malfunction in the natural gas equipment, you must not dismantle or repair it privately. At this time, you can call the gas company to report the malfunction, or you can ask Some professionals came to your home to repair it.

7. Common sense about the safe use of natural gas

Residents should pay attention to the following points to prevent gas accidents at home: (1) Stoves and water heaters with good quality and safety performance should be purchased and used, and fake and shoddy products should be avoided. It is the source of accidents; (2) Qualified personnel should be asked to install gas facilities according to specifications, otherwise there will be hidden dangers of accidents; (3) They should be used correctly according to the requirements of the product instructions, and the burning appliances should be regularly maintained (water heaters should be maintained for eight to ten years) months), any malfunction should be repaired in time; (4) Someone should look after the stove when using it, and pay attention to the ventilation of the environment where it is used. After use, do "two turns off and one on", that is, close the gas valve and kitchen door, and open it. Kitchen windows; (5) The gas facilities at home should be checked frequently, and aging rubber pipes should be replaced in a timely manner. It is best to use stainless steel corrugated hoses; (6) Install and use a gas leak alarm device, and hire a voluntary gas safety protector for the whole family.

How to deal with gas leaks? Check in time whether the switches and gas valves of gas appliances are closed properly; open indoor doors and windows for ventilation to allow gas to escape. If necessary, please go outside immediately and call the gas company's service hotline; if you find yourself or others poisoned by gas, go outside immediately to breathe fresh air, or send to the hospital for emergency treatment in serious cases; do not turn on any gas appliances or turn on electrical switches (including lights, neighbor doorbells), use telephones indoors (including cell phones), never use an open flame and use an open flame to test for the source of the leak.

Why should you install a gas leak alarm and cut-off device in your home? Artificial gas and liquefied petroleum gas both have obvious and special odors. Natural gas also has obvious odors after being odorized. If there is a leak, most people can smell it, but the elderly and children may not respond quickly, which may delay the opportunity. It can lead to poisoning, fire, explosion and other vicious accidents, resulting in serious consequences of family destruction and death. The smoke after burning gas contains the poisonous gas of carbon monoxide, which is colorless and odorless. This invisible killer harms many innocent citizens every year.

The national standard "General Safety Technical Principles for Gas Burning Appliances" GB16914 1997 stipulates that "gas leakage alarm and cut-off devices should be installed in the installation space of burning appliances", which is a scientific method to prevent gas accidents. Due to the high sensitivity of the gas leakage alarm and cut-off device, it will quickly alarm for trace amounts of harmful gases. Those with cut-off devices will immediately cut off the gas, thus effectively avoiding various gas accidents.

It is quite popular in developed countries, so gas accidents rarely occur. Installing a gas leak alarm and cut-off device in your home will create a voluntary gas safety protector for the whole family. How to check for air leaks in gas facilities? When you suspect air leakage in air pipes, valves, etc., you can handle it as follows: (1) Turn off all burning appliances (such as stoves, water heaters, etc.) and observe the last digit of the gas meter. After careful observation for a long time, there should be no leakage. walking phenomenon.

(2) Use soapy water or high-foaming detergent to brush valves, pipes, joints, etc. If there is bubbling, there is a leak. (3) Close the air inlet valve in front of the gas meter and ask maintenance personnel from the natural gas company to repair it.

(4) It is strictly forbidden to use open flames to check for leaks. Other safety matters When using natural gas, attention should be paid to exhaust ventilation all year round; gas pipelines should be installed in the open and must not be buried in walls or underground. They are strictly prohibited from passing through bedrooms, toilets, and bathrooms.

Do not seal the gas meter in the cabinet and maintain good ventilation. Places equipped with gas facilities are strictly prohibited from being used as bedrooms; do not move, disassemble or assemble indoor or outdoor gas facilities without authorization.

Please install the gas appliance and the flue for exhaust gas in strict accordance with the instructions of the gas appliance. And clean and maintain it every year to ensure smooth exhaust gas emissions and safe combustion; good ventilation should be maintained in places where gas appliances are used, so that harmful smoke after combustion can be discharged outdoors in time; indoor gas facilities should be checked frequently, and if any problems are found, Report repairs promptly.

8. What are the safety common sense of gas stoves

Safety common sense of gas stoves 1. First of all, when purchasing, be sure to ensure the gas source used at home and the stove you purchase. The required air sources are consistent, otherwise they cannot be used.

2. To ensure the safe use of the stove, be sure to purchase quality-assured pressure reducing valves and air pipes produced by regular manufacturers. 3. Users who use pipeline gas and natural gas must purchase products produced by large domestic professional manufacturers, which can ensure that their safety performance and thermal efficiency are in a better state.

4. When the stove is burning brightly, everyone should adjust the damper under the stove, which can adjust the mixing ratio of air and gas. 5. Once gas leakage occurs in the stove, do not panic. At this time, you cannot turn on the range hood, let alone light the stove. Instead, open the doors and windows for ventilation to allow the gas to dissipate automatically.
