Is freon from the refrigerator harmful? Electromagnetic field - impact on human health Are foods from the refrigerator harmful?

From a household point of view, a refrigerator is a very useful unit that adds a lot of comfort to our lives. However, British scientists have recognized it as one of the dirtiest kitchen items.

Initially, scientists set themselves the task of identifying the most contaminated kitchen appliances. During the experiment, they discovered that the most dangerous in terms of contamination with bacteria is the refrigerator, or more precisely, the drawer in it where vegetables are usually stored.

Information about the study was published in the Daily Mail. Bacteriological specialists counted about eight thousand pathogenic microorganisms per square centimeter in the vegetable compartment of the refrigerator - and this is a very high threshold of infection that poses a danger to human health. The standard level of contamination, generally accepted in European countries, can be no more than 10 bacteria per square centimeter.

According to microbiologists, among the detected microorganisms there were both salmonella and E. coli, as well as others, including rare bacteria.

Taking into account the information received, experts made conclusions that they readily share with Daily Mail readers:

• do not fill all the free spaces in the refrigerator to capacity - many pathogens (for example, listeria) love cramped and secluded places that are rarely ventilated;
• Before placing vegetables in the refrigerator, rinse them under running water to remove most of the bacteria;
• the box or tray for plant products must be thoroughly washed using detergents at least once a month;
• periodically inspect vegetables and fruits, throw away rotten specimens;
• do not put unripe vegetables in the refrigerator: first they must “reach” - for example, on a windowsill at room temperature;
• Do not store potatoes, garlic, onions, bananas in the refrigerator - in the cold they quickly deteriorate and contaminate other foods with bacteria;
• do not place vegetables or fruits and herbs on the same shelf: such a combination leads to increased release of ethylene, a gaseous substance that causes early rotting of fresh food;
• Promptly dispose of vegetables on which strange spots, “ulcers”, plaques have appeared, or if they have begun to emit a suspicious odor - after removing such specimens, thoroughly wash the refrigerator or at least the compartment where such vegetables were stored.

Of course, if you have a refrigerator of the latest generation, with precise electronics that allow you to create optimal conditions for food preservation, then many points of the recommendations can be missed. However, even high-end refrigerators should be washed and ventilated regularly - this simple rule will prevent a large number of different diseases that threaten us.

Many refrigerator breakdowns are accompanied by depressurization of the cooling circuit. Corrosion of the evaporator, violation of the integrity of the locking connections, breakdown of the evaporator with a knife, if you tried to knock off the ice in the freezer while defrosting the refrigerator - all this leads to failure of the unit and leakage of freon. And besides the question “what to do with the refrigerator”, the second one is no less reasonable - “is freon dangerous”? Could it be poisonous? Will the household be poisoned, especially if we have a standard 6-meter kitchen? We also have a gas stove - won’t it “explode”?

Let’s answer right away: in modern refrigerators, refrigerants of the brands R600a, R134a, R12 and R22 circulate. In those volumes that are available in household refrigerators, Freon leakage cannot cause harm to health or lead to an explosion or fire hazard.

In the table below we will consider in detail the main properties of freons in terms of their potential danger to humans and the environment (including the effect on the ozone layer).

As you can see from the table, even freons that are potentially dangerous to humans at room temperature and in the volumes that are available in household refrigerators cannot cause harm to humans. However, ventilating the room in the event of a freon leak will not hurt - for your own peace of mind.

How to determine what kind of freon is in your refrigerator?

If you are worried that your refrigerator was filled with some other refrigerant (which you think is very harmful and dangerous), we recommend that you find out the brand of freon the refrigerator uses. On the compressor of each refrigerator there is a special tag (sticker) indicating the refrigerant used. In addition, the type of freon is indicated in the technical data sheet of the unit.

With 99% confidence, we can say that your unit operates on one of the refrigerants described above (R600a, R134a, R12 or R22), which are not toxic and do not pose any danger to humans.

Signs of a freon leak

How can you tell if freon is leaking from your refrigerator? There are a number of signs that indicate a refrigerant leak from the refrigerator:

• If you were churning ice in the freezer, the tip stuck into the wall and you heard a hissing sound.- we are talking about a leak.
• Insufficient cooling, while the compressor runs constantly and does not turn off. If freon leaks, the refrigerator cannot reach the set temperature, and the unit tries to “compensate” for the lack of cold by constant operation. If the refrigerator has two compressors, one of the chambers will cool poorly, if it has a single compressor, both will cool.
• The motor doesn't turn on at all. After the freon has evaporated, the compressor does not “start” and the refrigerator stops working altogether.
• Fault signals. Modern refrigerators report when the temperature is above the set value. This may be a flashing hazard indicator or an audible signal.
• Visual cues. If there is a leak in the evaporator, there will be a large build-up of snow and ice on it (which indicates a malfunction). If traces of corrosion are visible around the perimeter of the freezer door, there is most likely a leak in the freezer perimeter heating circuit. In both cases, the refrigerator does not freeze or does not freeze well enough.

Most freons have increased fluidity, due to which they can evaporate even through the smallest microholes. That is why it is sometimes extremely difficult to determine the location of the leak. RemBytTech specialists use leak detectors for this - professional equipment that, based on the concentration of freon in the air, helps to find the location of the breakdown. It is impossible to do this yourself without the proper knowledge and special tools. That is why, in the event of a freon leak, we strongly recommend contacting professionals.

Everyone in their home has a useful household appliance called a refrigerator, which stores our food for a long time. Alas, like any device, it can break down, but in this article we will talk about the leak of “refrigerant”, the gas with which both chambers of the refrigerator are cooled, and we will figure out whether the freon in the refrigerator is dangerous or not, and we will consider its harmfulness to humans .

As mentioned above, refrigerator breakdowns may be accompanied by its depressurization and gas leakage from the chamber. Therefore, do not try to clear ice from the walls of the unit with sharp objects, as this may end badly for you. This is where the question arises among people: “Is freon from the refrigerator dangerous?”

Today, various brands of freon are used in refrigerator systems; below we will consider each of them separately:

1. Brand R 600 a or "isobutane" – perhaps the most common type of refrigerant, widely used in the cooling system of refrigerators. It is a mixture of natural gases, due to which it does not destroy the ozone layer of the atmosphere. However, it has a fairly high degree of explosion hazard upon contact with air. At high concentrations indoors, the mixture may ignite. As for the danger to humans, it can only cause harm in high concentrations - at the lower threshold of explosive danger, which is 31 grams of the substance per cubic meter of air. By standards, the most ordinary kitchen is 15 cubic meters, so to create such an environment you need 400 grams of this substance, but this will require a completely sealed room in which it cannot evaporate anywhere. There is no more than 150 grams of isobutane in the refrigerator itself.
2. Brand R 134 a or "tetrafluoroethane" - also an equally common type of freon, like the refrigerant described above. It is the first product developed without the use of Chlorine. It is a gas, absolutely colorless. It differs from its predecessor in that it is not toxic or explosive. Completely safe for humans in any environment and at any temperature.
3. Brand R 12 or "difluorodichloromethane" - mainly found in older refrigerators, so you won’t find it in modern units. It is a colorless substance in the form of a gas, but has a slight ether-like odor and is not explosive. It is harmful to the environment and can destroy the atmospheric ozone layer. As for whether freon from a refrigerator of this brand is harmful, then everything is as follows - with a high concentration of the substance in industrial premises (the volume in the air is about 30%) it leads to human suffocation. However, there is not enough of it in the refrigerator to create such an environment. If you heat it to a temperature of 330 degrees Celsius, it will begin to release toxic gases.
4. Brand R 22 or "difluorochloromethane" – exactly the same as the above type freon in the refrigerator, used in older refrigerator models, you won't find one like this today. It is a gaseous substance, completely colorless, non-flammable and non-explosive. Has a faint smell of chlorine. The substance can easily destroy the ozone layer, but its potential is tens of times less than that of the previous one. Capable of decomposing into harmful elements upon contact with flame. For humans, it becomes toxic only when it is heated to 250 degrees, when it begins to decompose into individual elements.

Despite the fact that freons in some cases are harmless or not at all dangerous to human life, it is best not to take risks and not come into contact with refrigerant substances.

How to find out what freon is circulating in your refrigerator

Finding out exactly what kind of freon you have in your refrigerator and its brand of refrigerant in your refrigerator is quite easy; to do this, you need to look at the compressor housing and find a special tag that will indicate the brand of freon used, or any other substance. If you do not want to move the refrigerator or there is no way to get to the back wall, then you can find out the type of refrigerant in the technical documentation.

There are many leakage factors, some of them are caused by humans, while others are due to manufacturing defects or careless transportation of the device, or the refrigerator is simply outliving its lifespan. They are as follows:

• When you were removing ice from the freezer, you accidentally pierced the wall with a sharp object, after which you heard a hissing sound from this hole - here we are talking about a direct leak of freon.
• The compressor is running, but will not turn off, and insufficient cooling of the unit’s chambers has been noticed - when freon leaks from the system, the refrigerator will not be able to maintain the set temperature, and it tries to compensate for this by continuous operation. If your refrigerator is two-chamber and has two compressors installed, then you can notice a decrease in temperature only in one of the chambers, and if there is only one compressor, then this will affect both chambers.
• The refrigerator “motor” does not want to start - If all the refrigerant has evaporated from the system, the compressor will not start.
• The control panel indicates a malfunction - Modern refrigerator models are equipped with information panels that indicate a malfunction in the system by flashing certain indicators. Typically, the meaning of these indicators is described in the device's operating instructions.
• You can also detect a leak visually - In this case, a small build-up of ice will form on the evaporator.

Most brands of freon have increased fluidity, so that at the slightest depressurization, the refrigerant can easily evaporate. It is often very difficult to determine the place where the passage of the substance occurs, since the gas is colorless, and due to the operation of the compressor, you may not hear hissing. In these cases, there is little you can do on your own; only specialists with special equipment will come to your aid.

Conclusion

For a refrigerator, freon is the most important element, without which it will not be able to function normally, therefore, as soon as you suspect its leak from the system, contact specialists as soon as possible.

We hope that we have answered your question: is freon in the refrigerator dangerous or not? As the manufacturers themselves indicate, it is harmless until it enters a certain habitat, where it begins to decompose into toxic substances. It’s better not to take risks, and if there is a leak, avoid inhaling the vapors of this substance.

Fridge. All family members know it and everyone, opening the door, hopes to find something for themselves there. At 12 o'clock at night, dad wants to see a piece of meat in it, mom wants a lot of fruits and yoghurts, although it happens that she wants the same thing as dad, and the children hope to get soda, sweets and the coveted ice cream from it. Of course, with regard to food safety, this is the main assistant and protector, but it turns out that it also carries with it a hidden threat…

The companies that produce these household appliances have strict requirements for the operation of the refrigerator and its placement in the apartment. So, for example, it is strictly forbidden to install them in bedrooms or children's rooms. He belongs in the kitchen. But even here it will be completely safe and here’s why.

The refrigerator has a fairly powerful electromagnetic field, the effect of which on the human body can hardly be called positive;
- refrigerant (freon), circulating in sealed tubes, and thus cooling the products inside the chamber is dangerous not only for the ozone layer of the Earth, but also for members of your family;
- microorganisms that multiply in the refrigerator if cleanliness and order are not maintained inside the device;
- who would have thought, but the magnets with which we are all accustomed to decorating our assistants pose a potential danger to a certain circle of people!

I would like to note that some time ago, manufacturing companies all over the world had to abandon classic freons, which, as it turned out, are capable of leaking even through sealed systems, causing harm to the ozone layer. They were replaced by “safe” refrigerants. This process was labor-intensive and cost a lot of investment.

The magnets on our refrigerator doors are also dangerous., especially if these are powerful magnets made of iron, neodymium and boron. Their dark color “gives them away”. The electromagnetic field they emit is tens of times greater than ferrite or iron ones, which are, in principle, safe for humans.

A particular danger, which is an integral part of dark or black magnets, is for people with weak hearts and those who have a pacemaker implanted. A malfunction of such a device due to an innocent magnetized memo from a resting place can be fatal.

But in my opinion, a refrigerator is a large “cabinet” of fresh food, the benefits of which far outweigh its harm. You just need to choose it correctly, giving preference to manufacturers who care about the safety of their consumers. I am sure that in this case a number of problems, such as evaporating toxic refrigerant, can be avoided in advance. Wishing you all the right shopping choices!
