The gas cylinder suddenly erupted and the fire was not extinguished for an hour, so why did the gas

Coal gas is a flammable and explosive gas, and at the same time it is also a toxic gas. Carbon monoxide and hydrogen in coal gas are very important for chemical raw materials. Excessive inhalation of these gases can cause people to coma and even cause death, so the relevant personnel in the gas plant often mix some unpleasant gases into the gas, the main purpose is to be able to find and take some defensive measures in time when the gas leaks.

The reason for the ** of the gas tank may be because the gas leakage temperature is very high and there is an open flame, according to the policeman Fang, the gas tank suddenly started to catch fire while cooking.

According to the report on **, on September 5, the police station in Weiping, Chun'an, Hangzhou, received a call for help from the name of the local village, saying that a family's gas tank was leaking and on fire. After receiving the alarm, the local authorities quickly rushed to the scene to deal with it. Later, on the way to the relevant personnel, the name of the village reported that the fire had been extinguished and there was no need to come again, but the relevant personnel decided to go to the scene to check in order to completely eliminate potential safety hazards.

When the relevant personnel rushed to the scene, they found that the gas cylinder of the caller was still spitting fire, and the policeman had planned to call ** again for helpBecause the house of the informant Fang is a very flammable civil structure house, and it is in the center of the village, surrounded by residential houses, and the fire that ignited is a gas canister, the situation is very dangerous.

At that time, the relevant personnel immediately evacuated the surrounding people and quickly moved the gas canisters to prevent the fire from spreading and endangering the surrounding people. When the personnel arrived at the scene, they had been burning for an hour, and after several attempts by the personnel concerned, the fire was unsuccessful, but the gas tank was already very hot at this time.

When we use fire in our daily life, we must standardize the use of fire, and have some relevant defense awareness, so as to minimize the occurrence of fire or reduce the threat to our life safety after the fire occurs. Fire is one of the most common and frequent disasters and has a great impact on the safety of our lives and property.

Because of the improper operation when cooking in the kitchen, the gas tank was constantly spewing fire.

The gas tank leak was extinguished at the beginning, but it re-ignited, and it was extinguished for more than an hour, and the firefighters quickly moved it to an open place for the safety of residents and houses.

Stress, pressure, and the environmental conditions in which you are exposed are all kinds of factors.

When a gas tank leaks and catches fire, don't panic and don't run away. The valve of the gas cylinder should be closed immediately, and the cylinder body should be cooled with cold water, and the gas cylinder should be covered with a rag, sack, bedding, etc. after immersion in water, so that the flame can be suffocated. If you find that the handwheel of the angle valve is not easy to close, or the pressure rises, and the gland is off and leaking, you should press and hold the handwheel of the angle valve with both hands, do not leave, let others tie it firmly with a rope, and then move the cylinder to a safe area and notify the gas company to deal with it.

If the angle valve is damaged and the gas source cannot be cut off, do not blindly extinguish the fire, you can quickly move the cylinder to a safe place outside, let it burn, and constantly pour water to cool down to prevent the cylinder from being heated. At this time, do not dump a burning gas canister on the ground. Because the gas cylinder is burned on the ground, regardless of whether the outlet is equipped with a pressure reducing valve or not, it generally does not occur**.

The gas in the horizontal cylinder will flow out through the mouth of the cylinder, rapidly expanding 250-300 times, and the high temperature will be generated during combustion, resulting in the gas cylinder ** hurting people. If you accidentally knock over the gas cylinder, you should put it up in time.

If a gas tank catches fire, it can be extinguished with a fire extinguisher such as dry powder and carbon dioxide. When extinguishing a fire with dry powder, if the dry powder is sprinkled on the root of the fire source, the fire will be extinguished immediately. But if you sprinkle it on the fire, it won't work.

The embers in the surroundings were not extinguished. It is not advisable to extinguish the flame of the ignition gas source to prevent the gas from spreading and diverting again.

What should I do if there is a gas fire? Don't be in a hurry anymore after reading it!

2.When the heating time of the gas tank is short, the valve of the gas tank should be closed immediately and the power supply should be cut off in time.

3.If the gas tank has been on fire for a long time or there is an open flame, remember not to close the valve or douse it with cold water! May cause **! In this case, evacuate to a safe place immediately.

If the gas tank has been on fire for a long time or there is an open flame, remember not to close the valve or douse it with cold water! May cause **!

Ask me if I use gas to turn on the switch, why is it still 0 or is there a gas leak.

The question did not catch fire.

I mean, I turned on the gas switch, and the needle was still at 0, whether it was leaking.

This kind of is more dangerous, you still call the person who sells liquefied gas to come and fix it.

Question: There is no gas canister, and the gas stove smells of gas.

We're in the mountains.

Check it out for yourself, it's dangerous and you can't be careless.

It's possible that the pipes are broken.

Cover with a damp quilt, hit 119, and run as far as possible. Of course, it's best not to let it catch fire, prevent it in advance, and eliminate hidden dangers. It's better than trying to figure out how to put out a fire!

Wrap it in a damp quilt and throw it out.

1 First cut off the air supply. If the flame at the valve port is large and cannot be closed immediately, you can use a dry powder fire extinguisher to spray at the root of the flame, or use a wet towel or rag to beat the root of the flame violently to extinguish the fire, and then close the valve.

2 After closing the gas tank valve, immediately move the gas tank to an open and unoccupied area. If you are unable to move the gas canister, cover your mouth and nose with a wet towel immediately, open doors and windows, and quickly leave the scene to take shelter in a place with fresh air.

3 If the fire is under control, call the designated gas company's customer service center** in a place where there is no gas leakage (e.g. outside).

4 If the fire is uncontrollable, leave the scene quickly after evacuating people and call the fire alarm **119 where there is no gas leakage.

Life skills, family prevention awareness!

The cylinder is generally not**, there will be a string of fire at the interface, cover it with a wet towel and other items and close the cylinder switch knob. If it cannot be closed, it needs to be moved to a safe area for alarm processing, and the overfire caused by cylinder leakage is also dangerous, and a protective area needs to be set up.

Someone else has already said what should be said. Supplement 1: When living on the first floor, when the gas tank is on fire for the first time, immediately go outside and pour cold water on the bottle without a fire extinguisher Do not pour it on the fire source to avoid gas poisoning, and then cover the fire source with a wet sheet and tighten the valve.

The purpose of watering is not to heat up the bottle**. When living on a high floor: Pick up a bottle and go into the bathroom, the method is the same as above to extinguish the fire, remember:

Pay attention to flammable materials when lifting cans. This method is summarized by fire training and experiments. If the oil pot is on fire, do not extinguish the fire with water and a lid or cloth, unless your lid is well sealed and the fire can be extinguished.

Turn off the air source first?? Are you trying to blow up a bunch of people?

1. When the gas tank leaks and catches fire, do not panic, close the valve of the gas cylinder immediately without igniting the nearby combustibles, cool the cylinder body with cold water, and cover the gas cylinder with wet towels and wet bedding to suffocate the flames.

2. If the liquefied gas leaks due to the damage and failure of the angle valve, the leakage should be wrapped with a wet towel first, and then the gas cylinder should be transferred to the outdoors to vent the residual gas, and remember to eliminate all fire sources.

3. It is best to always have a dry powder fire extinguisher at home, and when using it to extinguish the fire, you must cut off the fire source from the mouth of the gas cylinder, close the corner valve of the socks at the same time as the fire is extinguished, and remove the surrounding items that may cause combustion to prevent major accidents.

It should be noted that when the cylinder is standing and burning, it generally does not occur** and can be quickly extinguished. If the cylinder is poured on the ground or the pressure reducing valve is burning towards the ground, the personnel should not blindly approach, because the liquid in the horizontal cylinder will flow out through the mouth of the cylinder, rapidly expanding 250-300 times, and the high temperature will be generated during combustion, resulting in the gas cylinder ** injury. Of course, the most important point is to call the police in time.

Summary. Gas Tank Leakage Gas Tank Fire After being extinguished by water, it will not be **, because the gas tank is ignited by fire** because the gas expands in the tank due to combustion, and if there is no open flame to ignite the inside of the gas tank, it will not happen**.

Gas Tank Leakage: Will the gas tank catch fire and be extinguished by water?

Gas Tank Leakage Gas Tank Fire After being extinguished by water, it will not be **, because the gas tank is ignited by fire** because the gas expands in the tank due to combustion, and if there is no open flame to ignite the inside of the gas tank, it will not happen**.

In some cases, it is the best choice to let the gas tank continue to burn, because there is a high probability that the flame combustion will cause the valve to be damaged and malfunction, and the leaked gas cannot be converted into flames, and will accumulate in a small space, and there is a possibility of explosion or deflagration to a certain extent. In the figure, the gas tank with fire can be carried out, which is a rational choice made after the gas tank has been fully cooled in advance to ensure that it will not happen, as long as the cooling is sufficient, the relative risk is not particularly large.

No, don't worry! Thank you.

Summary. This is tempering and should be done by closing the valve on the stove first. After closing the big valve first, there is still gas in the pipe, which burns into the pipe and causes backfire**, so the common sense of fire protection says:

Try cleaning the lower blowhole.

This is tempering and should be done by closing the valve on the stove first. After closing the big valve first, there is still gas in the pipe, which will burn into the pipe to cause backfire**, so the common sense of fire protection says: once a fire occurs, do not close the valve on the liquefied gas tank first, you can close it small, and then close it after extinguishing the fire. FYI.

Summary. When the "overweight" cylinder is affected by factors such as high temperature exposure to the sun, baking, and sudden changes in the temperature difference between indoor and outdoor, it is very likely that the bottle body will occur.

After the user changes the gas tank, because the pressure regulator is not tightened or the sealing ring is aging, the connection leaks and ignites the connection. Fearing a fire, users often break the air duct and drag the cylinder outside the house to burn. At this moment, if the cylinder is lying down, so that the gas outlet burns towards the ground, the cylinder is partially heated by the flame of backburning, causing the pressure regulator to fail, and it will occur.

If the cylinder is used for a long time, lack of maintenance and repair, there will be rust, perforation, cracks, resulting in the loss of compressive strength, and a little high temperature, extrusion or collision is prone to occur. In addition, some users use hot water to pour, fire to bake cylinders and other methods to promote liquefied gas fire, which is also very dangerous!

What is the case with a gas canister**.

Hello, I have seen your question and am sorting out the answer, please wait a while

When the "overweight" cylinder is affected by factors such as high temperature exposure to the sun, baking, and sudden changes in the temperature difference between indoor and outdoor, it is very likely that the bottle body will occur. 2.After the user changes the gas tank, because the pressure regulator is not tightened or the sealing ring is aging, the connection leaks and ignites the connection.

Fearing a fire, users often break the air duct and drag the cylinder outside the house to burn. At this moment, if the cylinder is lying down, so that the gas outlet burns towards the ground, the cylinder is partially heated by the flame of backburning, causing the pressure regulator to fail, and it will occur. 3.

If the cylinder is used for a long time, lack of maintenance and repair, there will be rust, perforation, cracks, resulting in the loss of compressive strength, and a little high temperature, extrusion or collision is prone to occur. In addition, some users use hot water to pour, fire to bake cylinders and other methods to promote liquefied gas fire, which is also very dangerous!

If the liquefied gas cylinder catches fire, different disposal measures should be taken according to the on-site situation. In general, there are two situations:

1. In the case that the valve of the liquefied gas cylinder is intact, the first choice is to close the valve, and the fire will be extinguished when the valve is closed. The situation of "extinguishing the fire first, then closing the valve, otherwise it will backfire and lead to **" circulating on the Internet will not happen when the liquefied gas cylinder catches fire. Only when the gas pipeline is on fire, if the valve is closed quickly, the pressure in the pipeline will drop rapidly, and the pressure outside the pipeline is greater than the pressure inside, and the fire will be pressed into the pipeline to cause backfire.

When dealing with a gas pipeline fire, firefighters will first slowly close the pipeline valve to a minimum, and then close the valve to extinguish the fire after the flame is reduced to a minimum. This is done to prevent flashbacking. The body and mouth of the liquefied gas cylinder are small, the pressure is relatively small, and there will be no pressure difference, and the pressure inside the liquefied gas cylinder is greater than that of the outside.

2. If the valve of the liquefied gas cylinder on fire is damaged, you can not extinguish the fire, first carry the liquefied gas cylinder to an open area and stand up, then cool the bottle body with water, and wait for the liquefied gas to burn completely; If the burning liquefied gas cylinder cannot be transferred in the resident's home, the fire can be extinguished first, and then the bottle mouth can be blocked with a wet rag and other items, and sent to a professional liquefied gas station for disposal. The fire department reminds that if the liquefied gas cylinder is burned horizontally, the cylinder is easy to be heated by the flame, and after reaching a certain temperature, the liquefied gas in the cylinder is heated and expanded, and the cylinder body is prone to physical **.

Therefore, after the liquefied gas cylinder catches fire, in the case of unpredictable and incapable disposal, it is necessary to call 119 to call the police as soon as possible, wait for the firefighters to arrive at the scene to deal with it, and do not let the burning cylinder fall to the ground.
