Why can t you use water to extinguish the oil pan fire?

We have just finished talking about the truth that water can extinguish fires, and now we say that when the oil pan is on fire, it cannot be extinguished with water.

Oil is an organic substance, one of its chemical properties is flammable, and it is important to note that the density of oil is less than that of water. If the oil catches fire and splash it with water, <>

When water is poured into the pot, because the oil is relatively light, it will float on top of the water, still in contact with the oxygen in the air, and burn violently. Moreover, after watering, the oil will be dispersed into a larger area, increasing the contact surface between the oil and the air, which in turn will make the combustion more intense. Therefore, water not only does not extinguish oil fires, but also has a counterproductive effect.

In addition, a high-temperature oil pan with a temperature of well over 100 degrees Celsius will instantly heat up the water, causing the hot water to splash out, and the oil fire will also splash elsewhere, which can easily cause the fire to spread and people**. Therefore, when the oil pan catches fire, it should never be doused with water. The correct way to extinguish a fire in an oil pan is:

Pour the cold dish into the pot and the fire will automatically extinguish; Or quickly cover the pot with a lid so that the burning oil fire does not touch the air and extinguishes.

Firefighters poured cooking oil into the pot and lit it to heat it, and after more than ten minutes, a large amount of smoke began to come out of the oil pan and burn. After the firefighters turned off the fire, the oil in the pot was still burning, and then the firefighters slowly poured the cooking oil along the edge of the pot, and a magical scene occurred: the flames that had been burning violently began to gradually extinguish.

The result of the experiment was that "adding fuel to the fire" would extinguish the fire, but it should be poured slowly along the edge of the oil pan. How does this work?

Covering the high-temperature oil with low-temperature oil can quickly reduce the temperature in the oil pan, and when the oil temperature drops below the ignition point, the fire will be extinguished, which is the principle of oil extinguishing fire. Hu Yingtao, instructor of the Weiwu Road Squadron of the Fire Brigade of the Development Zone, explained that this method is effective, but it takes a long time.

As the saying goes, "fire and water are incompatible". Once the oil pot is **, the first reaction of many citizens is to extinguish the fire with water. So, what will happen if you pour water into the oil pan of **?

When the firefighters poured a bowl of water into the burning oil pot, the flames exploded quickly, and the flames generated were more than two meters high, and the reporter could feel a heat wave from a distance of four meters, and the fire kept burning until the oil burned out.

Therefore, when the oil pot is **, you must not use water to extinguish the fire, because the oil is lighter than water, and floating on the water surface can not produce the effect of isolating the air, and splashing water will cause oil splashes, which is easier to expand the fire area.

When we stir-fry in our daily life, if we forget to turn off the heat, there may be a situation where the pot is on fire. After the fire situation occurs again, we must not panic, but deal with it calmly; The correct way to do this is to cover the pot first, then use a damp rag to extinguish the remaining embers, and finally close the gas valve.

During the whole process, do not use water to directly extinguish the fire, and the reason why you can't use water to extinguish the fire is because of the following two reasons:

1. Water will make the oil splash out and make the fire bigger.

If we use water to extinguish the fire after the oil pan catches fire, the oil will quickly splash on the stovetop, and the whole cooktop will become a sea of fire. And in this process, if the oil splashes on our body, it will burn our **, which is a great threat to our personal safety.

Under the action of water, the gas will also be extinguished, and there will be gas leakage, if not detected in time, it will bring us greater safety hazards. So after the oil pan catches fire, try not to use water to extinguish the fire, which is a dangerous behavior.

Second, the use of water will damage the kitchenware.

After the oil pan is on fire, if we use water to extinguish it, it will also let the water enter the stove while extinguishing the fire; It is very likely that we will not be able to catch fire because of this, which will affect our cooking. If this happens, it can only be dealt with with by warranty after-sales.

Of course, the use of water will also make a mess in the house, which may make the dry food damp, and make the whole house full of grease, which will increase the workload for your later cleaning.

Therefore, dousing the oil pan with water is really not a good solution!

Based on the above two aspects, after the oil pan is on fire, we must deal with it calmly, cover the oil pan with a lid as soon as possible, and wait until the domestic air is exhausted, and the fire will naturally be extinguished. During the whole process, the use of water to extinguish the fire is the most taboo, because the water may add fuel to the fire, causing many inconveniences and dangers to oneself.

When cooking, sometimes the oil pan will accidentally catch fire, and at this time, some people's first reaction is to pour water into the oil pan. Doing so will not extinguish the fire, but will make the fire burn more and more. What is the reason for this?

Since oil and water are not miscible, when you pour water, it will cause hot oil to splash everywhere, which may hurt yourself and the people next to you. And the oil is lighter than water, the water not only can not cover the oil, but will sink to the bottom of the oil layer, can not play the role of isolating the air, the water supports the oil, so that the contact area between the oil and the air increases, the fire will burn more vigorously, so can not be extinguished with water.

So, what should you do after the oil pan catches fire? First of all, turn off the fire source and quickly cover the pan with a lid or a damp rag to isolate the burning flame from the air, and the fire will be extinguished due to lack of oxygen. In addition, you can also put chopped vegetables into the pan to cool the pan and eventually extinguish the fire.

It is common knowledge that water can extinguish fires. Because combustion must meet two conditions, the first is to have enough oxygen; The second is to reach the combustion temperature ——— ignition point. When fighting fires, try to destroy these two conditions.

When extinguishing a fire with water, water can lower the temperature of the burning object, not because the temperature of the water itself is low, but because the water is sprayed on the fire and immediately turns into water vapor. When water turns into water vapor, it takes away a lot of heat, which reduces the temperature of the burning object; In addition, when water turns into water vapor, it is enveloped in the combustion body, isolating the air and cutting off the oxygen supply, so the water can extinguish the fire. If you douse water on oil when it catches fire, it would be a big mistake.

This will make the fire even bigger, like "adding fuel to the fire". Why can't oil fires be extinguished with water? It turns out that oil is lighter than water, and when water is sprayed on the oil, the water cannot cover the oil, but all sinks to the bottom of the oil layer, so it cannot isolate the oxygen of the **; In addition, the water sinks below the oil, where the temperature is lower, and the possibility of the water turning into vapor is very small, which does not help to isolate the oxygen.

In addition, the water is flowing, and it will float around with the burning oil, expanding the scope of combustion, increasing the contact area between the fire and the air, and the fire will burn more and more. Therefore, when the oil catches fire, do not use water to extinguish it. So when the oil catches fire, what is the method to deal with?

If you accidentally catch fire while stir-frying, what is the way to deal with it? Put the lid on the pot to isolate the oil from the air, and the fire will be quickly extinguished. If the gasoline drum catches fire, use a foam fire extinguisher.

As soon as the foam fire extinguisher is turned upside down, a large amount of foam is sprayed from inside, the foam contains a large amount of carbon dioxide gas, carbon dioxide will not spontaneously combust, nor does it support combustion, and it is heavier than air.

Hello, this is mainly because water added to the oil can cause the oil to splash everywhere and may eventually cause a more serious fire.

If you encounter similar problems in the future, you can follow the following ideas to solve them:

1. Finding problems: often living in the world, always in these kinds of contradictions, when some contradictions are projected into consciousness, the individual only finds that he is a problem, and asks to find a way to solve it. This is the stage where the problem is discovered.

From the perspective of the stage of problem solving, this is the first stage and the premise of solving the problem.

2. Analyze the problem: In order to solve the problems found, it is necessary to clarify the nature of the problems, that is, to figure out what contradictions there are, which contradictions, and what is the relationship between them, so as to clarify what results the problems to be solved, the conditions that must be met, the relationships between them and what conditions have been met, so as to find out the important contradictions and key contradictions.

3. Put forward hypotheses: on the basis of analyzing the problem, put forward hypotheses to solve the problem, that is, the solution that can be adopted, including what principles and specific ways and methods to take, but all of these are often not simple and ready-made, and there are various possibilities. However, putting forward hypotheses is the key stage of problem solving, and correct assumptions lead to the smooth solution of the problem, while incorrect and inappropriate assumptions lead to detours or lead the solution of the problem astray.

4. Verify the hypothesis: The hypothesis only proposes n possible solutions, and there is no guarantee that the problem will be solved, so the last step in problem solving is to test the hypothesis. In either case, if the test does not produce the expected result, a new hypothesis must be proposed and tested again until the correct result is obtained, and the problem is not solved.

Because water is denser than oil, if it is extinguished with water, the water will sink underneath the oil. Then the oil will be on the surface of the water and will not be able to extinguish the fire.

Basically, when the oil pan continues to heat, it will burn at about 400 degrees, and many people will panic when they see the fire, and their intuitive reaction is to use water to extinguish the fire, but they forget that the oil will be more dangerous when it touches the water! So, how to deal with it when the oil pan is **? In fact, as long as you keep these three steps in mind, you can successfully extinguish the first step:

Calm down, turn off the fire oil pot** quickly calm down, and turn off the heat, so as not to continue to heat the pot and keep burning. Step 2: Wet the rag and cover it directly on the pot to block the circulation of the flame and the outside air. If the fire is not large, you can also directly cover the pot to let the flame stop naturally.

The most important thing to cover the lid is to remove the lid slowly. Turn off the gas and wait for the temperature in the pot to drop before lifting the lid. It is dangerous to cover the pot from the top down, and from the top down, the fire will spray out from the side of the pot lid, and it is easy to burn your hands.

The correct way is to slowly close the lid from the side. Step 3: Wait for the fire to go out naturally, don't try to move the pot Moving the pot may cause unnecessary danger, and when the fire is smoldered, the crisis can be resolved.

In addition, if you have enough vegetables at hand, throw them away and use the temperature difference between the vegetables and the burning oil to cause the temperature of the burning oil in the pot to drop quickly (a large amount of vegetables is required).

After the oil pan catches fire, if the fire is extinguished with water, the water will explode when it encounters the hot oil, and the boiling oil and water will scatter and disintegrate, causing a larger area of fire, and even people who are close to it will be affected by this.

The reason is that water is heavier than oil, so it does not play a role in extinguishing fires, and if you want to extinguish the fire in the oil pan, then you must isolate the air and cover the pot. In this way, the effect of extinguishing the fire can be achieved. Therefore, when we put out the fire, we should choose the appropriate way to extinguish the fire.

The density of water is greater than that of oil, and when you pour water into a pot, the water will sink to the bottom of the oil layer, where the temperature is lower, and the possibility of water turning into vapor is very small, and it cannot completely isolate oxygen; In addition, the flowing water will carry the burning oil everywhere, expanding the scope of combustion, increasing the contact area between the fire and the air, and the fire will burn more and more.

Because the water falls into the hot oil pan, it will oil the water, and the splash of oil will hurt the person who put out the fire.

What is the easiest way to extinguish a fire in an oil pan 1Don't be in a hurry when the oil pan catches fire, cut off the fire source first. 2.

Be especially careful not to try to extinguish it with cold water, as this will only increase the fire. 3.You can use the lid of the pot to cover the oil pot and use the principle of air isolation to achieve the purpose of extinguishing the fire.

4.If the lid of the pot cannot be tightly lid to achieve the effect of isolating the air, you can also put a large number of vegetables to achieve the purpose of extinguishing the fire.

You can't use water to extinguish oil fires because oil is lighter than water, and water sinks underneath the oil, so it can't isolate oxygen**.

Alcohol, gasoline, edible oil, oil-based paint, banana water, etc. are all organic solvents or contain organic solvents, and once burned, they cannot be doused with water. Because the specific gravity of these solvents is less than that of water, after watering, the water cannot cover them, but quickly "runs" underneath them, and does not play the role of isolating oxygen. Watering also increases the contact area between the organic solvent and the air, making the fire burn more vigorously. At high temperatures, water boils rapidly, vaporizes, and even splashes burning organic solvents around.

The specific gravity of water is greater than the weight of oil, and a dry powder fire extinguisher should be used when the oil catches fire. If a household oil pot catches fire, you can use the lid to isolate it from the air to extinguish the fire.

1. The specific gravity of oil is smaller than that of water and floats on it. Extinguishing oil fires with water makes it easier for the fire source to spread with the flow of water.

2. As soon as the water touches the high-temperature oil that has been burned, it will cause the ignition source to spread with the splashing of water. Therefore, only yellow sand or other fire-fighting materials that can extinguish oil fires can be used to extinguish oil fires.

The principle of extinguishing a fire with water is two points, one is to isolate oxygen, and the other is to evaporate water on the surface of combustibles to cool down.
