Is it safe to use gas tanks?

Question 1: Are household liquefied gas tanks generally safe? I'm always afraid of gas tanks, and I wonder what the safety risks are. 1. Change the pipe frequently, once every six months, so as not to age. 2. The thread must be aligned and tightened, don't screw it off. 3. Remember to use it every time. Turn off the main gate, and don't listen to that person who said to try it with a lighter, it's so dangerous

Question 2: Is it safe to use a gas tank? What are the dangers of a gas tank? "Gas tank" is a mobile pressure vessel made of steel, which has the risk of explosion. Its wall thickness is only about 2.5 mm (the factory-calibrated wall thickness of new cylinders), which is very thin. It is always under pressure from the internal medium and cannot be used normally. When the internal pressure (i.e. pressure) is 0.5 to 1.2 MPa (5 to 12 kgf/cm2), the entire cross section must bear a tensile force of about 1,000 kg.

The "gas tank" is filled for a long time. Damage caused by collision, exposure, and medium corrosion during transportation and use will produce fatigue cracks, pits, deformations, corrosion thinning and other defects. These defects are the direct cause of explosion accidents. You have seen "gas tanks" explode. Is it a scene?

When a "gas tank" explodes, it will cause two damage instantly. The first is a physical explosion when the tank ruptures. The liquid petroleum gas instantly expands 250 to 300 times and turns into a gaseous state, generating a shock wave, such as Landmine explosion. The petroleum gas that becomes gaseous mixes quickly with air. When the concentration in the air drops to 3-11%, a chemical explosion will occur if exposed to an open flame. The entire gas space will explode and burn, producing a huge shock wave, harming lives. , burning property, destroying buildings, and causing secondary disasters. If a person inhales this explosive gas, it will cause burns to the respiratory tract and lung tissue, which is extremely terrifying.

In order to protect people's lives, the State Council promulgated. The "Regulations on Safety Supervision of Special Equipment" lists liquefied petroleum gas cylinders as legally monitored equipment. "Gas tanks" are not permanent durable goods. Professional technicians have measured the safe use period of "gas tanks" through analysis of a large number of accident cases and scientific tests. There are only 15 years. During this period, regular inspections must be carried out every 4 years to detect existing defects. This is a safety guarantee for you and your family, and is also stipulated in the "Gas Cylinder Safety Technical Supervision Regulations"

The current selling price of LPG cylinders on the market is about 100 yuan, which is less than the price of a shirt. You must not be stingy and be reluctant to renew it. If it expires, it will be a disaster for your family. I remind you again, buy a "gas tank". "Go to a fixed store, not the free market, where there are many counterfeit and shoddy goods.

Don't sell your discarded cylinders as ordinary scrap metal, and don't dispose of them yourself, as this can easily lead to accidents , the cylinder must be sent to the local Quality and Technical Supervision Bureau or Boiler and Pressure Vessel Inspection Office for destructive treatment. Otherwise, it may fall into the hands of others and may be refurbished and then put into the market to harm others.

What do you think about " If you have any questions about the safety of "gas cylinders", please contact the Bureau of Quality and Technical Supervision, which is responsible for the supervision of gas cylinders.

"Expired service" is not actually "use period exceeds 15 years" as everyone understands, but It refers to a gas tank that must be inspected after a certain period of use (such as 3 years) but has not been inspected. The normal service life of a gas tank is generally 15 years, and it should be inspected every 3 years. Those that are never inspected or "extended service". Gas tanks are like time bombs. First of all, from the production of gas tanks, qualified gas tanks should be produced by regular manufacturers in accordance with my country's safety technical specifications and national standards, and have a dead weight of 16.517 kilograms. However, some manufacturers do not produce according to national standards and cut corners, which first leads to quality problems. Gas tanks must be subject to supervision and inspection one by one before leaving the factory. When leaving the factory, the manufacturing unit shall indicate the manufacturing unit's manufacturing license number and enterprise code mark as well as the gas tank factory serial number on an obvious location on the product. The gas tank valve manufacturing unit should ensure that the gas tank valve is used safely until at least the next inspection cycle of the gas tank. The service life of the gas tank is 15 years, and it should be inspected every three years. For safety reasons, be sure to go to a regulated filling point when buying a gas tank. In order to reduce the corrosion of the inner wall of the gas tank and extend the service life of the gas tank, be sure to go to a regular filling point to inflate.

Gas tanks are close to fire and heat sources such as stoves and heaters, and gas expansion and explosion are easy to occur. Therefore, the distance between the gas tank and the stove should be kept at least one meter, and the parts on the gas tank should be checked frequently to prevent gas leakage.

Question 3: How to use gas safely? 1. What should you pay attention to before using gas?

When using gas, you must pay attention to whether there is a smell, confirm that there is no gas leakage before turning on the gas, and pay attention to good ventilation.

2. What should you pay attention to when using gas cylinders?

1. Please pay attention to the inspection period for cylinders and attach inspection qualification standards.

2. Please keep the cylinder upright and avoid violent vibrations.

3. Place it in a well-ventilated place away from sunlight.

4. Do not use the cylinder upside down.

5. Do not place objects on the cylinder to avoid ignition.

3. How to check whether the gas pipeline is leaking?

When you suspect there is a leak in the gas pipe (pipeline) in your home, do not use a match or lighter to test for leaks. Instead, use soap bubbles to check for leaks.

4. Where is the safest place to install a gas water heater?

It should be installed outdoors in a well-ventilated area to avoid accidents of carbon monoxide poisoning.

5. What is the phenomenon of red flames in gas fireworks? What's the danger? How should this be handled?

The gas flame is normally light blue. If it is found to be red, it means incomplete combustion. There is a risk of carbon monoxide poisoning, so you should immediately ask a gas professional to check and adjust the stove.

6. How do you know about the gas leak?

1. Smell - Domestic gas is mixed with odorants, and there will be a self-odor when it leaks.

2. Vision - Gas leakage will cause mist-like white smoke to form in the air.

3. Hearing - there will be a "hissing" sound.

4. Touch - your hand will feel cool when it is close to the leakage hole.

7. How to deal with gas leakage? Valve 1. Turn off the gas switch immediately.

2. Never turn on or off any electrical switch.

3. Gently open all doors and windows and quickly escape outdoors.

4. Call the alarm.

8. Will gas kill people?

1. Gas itself is not toxic, but it has anesthesia and suffocation properties, which reduces biological reaction capabilities.

2. When gas is used improperly, a large amount of carbon monoxide will be produced. Carbon monoxide can easily combine with heme in the blood, causing anoxic state (carbon monoxide poisoning, leading to death).

9. What should you do if the gas air is insufficient and carbon monoxide poisoning occurs?

1. Turn off the gas switch.

2. Open doors and windows for ventilation.

3. Provide the injured with fresh air.

4. Untie the restraints and clear the respiratory tract.

5. Perform artificial respiration or cardiopulmonary and abdominal compression as needed.

6. Do not turn on or off any power switch until the gas smell has dissipated to avoid sparks and fires.

11. What are the symptoms of carbon monoxide poisoning?

1. Headache, dizziness, nausea and vomiting. 2. There will be a strong sense of collapse, accelerated breathing and pulse, confusion of consciousness, and the inability to move the body on its own. 3. Flushed face, loss of consciousness, respiratory arrest, convulsions, leading to cardiac arrest and death.

12. What should I do if the gas pipeline is accidentally cut due to sewage pipeline construction?

If the gas pipeline is accidentally cut due to sewage pipeline construction, citizens are asked to immediately turn off the fire source at home. If the pipeline catches fire, do not put out the fire rashly. Draw a warning line and call the police as soon as possible. Nearby residents or passers-by should avoid smoking, starting cars, motorcycles, and various power switches to avoid explosions or burning. Personnel should stay as far away from the scene as possible. Before handling personnel arrive at the scene, citizens are asked to surround the scene with ropes. , and write slogans such as gas leakage to remind passing people and vehicles.

Question 4: How to use gas cylinders safely? 1. Gas cylinders should be used upright and are strictly prohibited from being turned upside down.

2. Users are not allowed to handle or dump the remaining liquid in the bottle without authorization. Although these residual liquids are difficult to vaporize, they will burn immediately if exposed to an open flame.

3. Prevent the pressure reducing valve from leaking. Users should always check whether the sealing rubber ring on the pressure reducing valve is aging or falling off. Once the rubber ring is aging and falling off, it should be replaced immediately, otherwise gas leakage accidents will occur. When it is found that the valve body itself is leaking, it should be sent for repair or replacement immediately.

4. Check whether the hose is aged, cracked or damaged to prevent air leakage. The hose should be a special hose for liquefied gas, and the two ends connecting the pressure reducing valve and the stove should be locked with stainless steel clamps.

5. Stoves must be used safely. Stoves should be placed away from flammable materials and at a certain distance from gas bottles; stoves, pressure reducing valves, hoses and other accessories should be kept clean. Develop a good habit of not leaving the stove when it is in use, and turning off the switches (including the main switch of the gas cylinder) when the stove is not in use. Once you find that the stove is leaking, you should ask professional maintenance personnel to repair it.

Question 5: Are gas tanks safe to use? What are the dangers of gas tanks? Although gas tanks are convenient and quick to use, they are also dangerous. It is recommended to use gas tanks correctly to avoid fire hazards.

1. If it is not moved or encounters high temperature, it will not explode. It doesn't have to be fire, as long as it is high temperature, when the pressure inside the bottle exceeds the strength of the cylinder, it will explode.

2. More powerful than grenades. According to relevant information, the explosion power of a liquefied gas cylinder is equivalent to 5 times that of TNT explosives. For example, if the 12 kilogram steel cylinder we use daily explodes, the damage caused is equivalent to the consequences of the explosion of 60 kilograms of explosives. Moreover, once a fire occurs after liquefied gas leaks, the burning speed is as high as tens of meters per second, making it very difficult to put out the fire.

Generally speaking, there is no danger if there is no air leakage or high temperature.

There are certain dangers in using gas. Generally, the gas will not leak when the valve is closed (unless the point is too low). Also, do not use the old one that has lost its teeth. It is recommended to replace it with another one. Reuse the new valve; to daily check whether there is air leakage after closing the valve, you can close the valve and see if it can still ignite. If not, it will be fine. If you really can't let it go, why don't you spend money to buy a gas detector and put it in that house? If there is gas, it will be safe. Cooking with gas still saves money, as long as you always pay attention, it will be fine.

Question 6: Are gas tanks safe to use? What are the dangers of gas tanks? My friend, I suggest you use an induction cooker, because the price of gas has increased significantly now, and electricity is more economical. In addition, using an induction cooker is much safer than using gas from any angle. The only disadvantage is that you are afraid of power outages. As for gas, if your space is not large and there is no ventilation, it is indeed easy to be poisoned by gas, but the chance is not high.

Question 7: Are gas tanks safe to use? What are the dangers of gas tanks? There are certain dangers in using gas. Generally, the valve on

will not leak gas if it is closed (unless the point is too low). Also, don’t use old ones that have lost their teeth

It is recommended to replace the valve with a new one before use; to check whether there is air leakage after closing the valve on a daily basis, you can close the valve and see if it can still light the fire. If not, it will be fine. If you really don't let it go, it would be safe to spend money to get a gas detector and put it in that house. If there is gas, it will call the police. Cooking with gas still saves money, as long as you always pay attention, it will be fine.

Question 8: Where is Bamian City in Liaoning? Bamian City is in Changtu County, Tieling City, Liaoning Province. "Changtu" is the transliteration of the first two characters of the Mongolian "Changtu Erke", which means "green prairie". It is located in the northernmost part of Liaoning Province, on the southern edge of the Songliao Plain, and borders Siping City, Jilin Province in the north. In the west, it faces the Inner Mongolia Horqin Zuoyihou Banner across the river

Question 9: Are gas tanks safe to use? What are the dangers of gas tanks? There are definitely dangers in using gas tanks, but don’t worry too much:

1. Once an accidental gas leak occurs, do not turn on any electrical equipment, including turning on lights, exhaust fans, range hoods, televisions, radios, making phone calls, etc. Open doors and windows for ventilation in a timely manner, and report to the gas company promptly.

2. Gas appliances must be qualified products from regular manufacturers, and they must not be greedy for temporary gains and create hidden dangers of accidents.

3. When installing a gas water heater, you must ask a professional team to perform the installation in a standardized manner. When using the water heater, you must maintain good indoor ventilation.

4. When using gas, someone must be in front of the stove to supervise it. Check whether the gas valve is closed before going out and before going to bed every day.

5. During interior decoration, gas facilities must not be moved, gas meters, gas pipes, etc. must not be installed in cupboards, and gas valves must not be sealed.

6. The gas stove cannot be placed directly below the gas meter. It must be staggered by more than 30 cm directly below the gas meter to prevent the gas meter from being exposed to heat or moisture.
