Formaldehyde is toxic. Formalin. What is this substance? Symptoms and signs of poisoning

Formaldehyde (formalin) is a fairly toxic substance and, if ingested, causes serious poisoning. Previously, its use was limited to leather tanning, medicine and laboratory research, and the production of plastics, but now formalin can be found everywhere. Such a spread of a toxic substance could not but affect the increase in the statistics of poisoning.

Scope of formalin

Formaldehyde is a colorless toxic substance that has a sharp unpleasant odor and is highly soluble in water and alcohols. It is mainly used in the form of a 40% aqueous solution - formalin. Chemical properties substances cause its high danger to human life and health: ingestion of 2-6 tablespoons of the solution can be fatal.

Currently, the use of formaldehyde is limited to medicine and industry. The harmful solution is found in nail polish and keratin hair straighteners. A small amount of the substance (0.1-0.5%) is also acceptable in other cosmetics as an antiseptic and preservative, it can be contained in shampoos, mouthwashes, creams, antiseptic solutions and gels, deodorants.

Compositions with formaldehyde are used in everyday practice by doctors and students of medical universities, employees of laboratories for the manufacture of cosmetics, workers in factories for the manufacture of furniture and leather tanning. People may be systematically exposed to toxic fumes in Everyday life, but a single inhalation of a small amount of formalin will not lead to dangerous consequences.

Is it possible to independently determine the presence of formalin in everyday products, how does the product smell? Formaldehyde has a pungent odor, but it is almost impossible to accurately identify the substance at home: you need to use laboratory equipment, chemicals and have the appropriate knowledge.

What does formaldehyde smell like? It is difficult to draw an analogy with other aromas, the smell of formaldehyde is very specific. The main active substance of the antiseptic "Formidron", which is sold in pharmacies, is just formalin. You need to smell the product carefully, directing the vapor towards you with a movement of your hand.

Sources of intoxication and the permissible norm

Toxic substances are divided into several hazard classes, which are determined by the properties specific means. The properties of formalin make it possible to attribute it to the second hazard class, which is explosive and has a negative effect on humans when ingested.

There are many sources of formalin intoxication. The highest concentration of the substance is concentrated in furniture (poor-quality production), urban smog, tobacco smoke (including from electronic cigarettes), car exhaust, near open fireplaces and gas stoves. Formalin poisoning can occur from inhaling the smell of new carpets, certain cosmetics and household chemicals, adhesives, fertilizers, and drugs. The maximum concentration of formaldehyde in the air is reached under conditions of high humidity and temperature.

Maximum sanitary standards allowable concentration(MAC) of the substance is up to 0.2% in cosmetics and up to 0.1% in oral care products. The permissible percentage of formalin in pharmaceutical preparations is less than 0.5. Medicines containing more than 5% formaldehyde may also be used, but should not be applied to the face.

Laboratory studies have confirmed that the MPC complies with sanitary standards. An adverse dermatological reaction to shampoo and bath foam containing 0.1% formaldehyde occurred in just one out of 75,000 people taking part in the study.

The effect of formaldehyde on the body

The effect of formaldehyde on the human body is extremely negative - the substance causes severe intoxication, which is comparable to or hydrocyanic acid. The central nervous system, mucous membranes and respiratory organs are most affected.

Why is formaldehyde dangerous? Systematic exposure leads to severe poisoning and dangerous complications. Among the consequences of intoxication can be listed:

swelling of the larynx and lungs, which lead to difficulty breathing and even respiratory failure, which can be fatal;
hemorrhagic nephritis - an inflammatory process localized in the kidneys;
violation of the menstrual cycle and hormonal balance, which are a common cause of infertility in women;
anuria - a clinical symptom characterized by the absence of urine, in the most severe cases, the condition leads to coma.

In addition, the danger of formaldehyde is the fact that sensitivity to poison increases over time, which contributes to the development of complications with the systematic exposure to a toxic substance.

Symptoms and signs of poisoning

Formaldehyde poisoning is characterized by a number of symptoms, mainly from the side nervous system, to them are added symptoms of indigestion and irritation of the respiratory system. Signs of chronic formaldehyde poisoning are as follows:

cough and difficulty breathing. asthma attacks;
burning of the mucous membranes, as well as in the pharynx, stomach and along the esophagus;
diarrhea and vomiting with an admixture of blood, thirst;
pallor of the skin;
weakness and fatigue;
insomnia and cramps at night;
impaired coordination of movements;
irritability, frequent mood swings;
severe headaches;
intense weight loss.

In people who regularly come into contact with formaldehyde, the symptoms are supplemented by allergic skin reactions, dermatitis, eczema, and brittle nails. The drug has a negative effect on reproductive function: women may experience menstrual disorders, men - lack of sexual desire.

The action of formaldehyde in high concentrations can cause toxic shock and coma. Even one tablespoon of the solution, deliberately or accidentally taken orally, in some cases is fatal.

Emergency care and further treatment

In case of acute poisoning, a person should be taken to fresh air, inhaled with a solution of water and ammonia, which eliminates excess formalin. Mucous membranes and skin must be washed large quantity water. The skin is additionally washed with a 5% solution of ammonia. In the eyes (if the substance got on the face), drip a few drops of the following composition: add 8 drops of adrenaline and a couple of drops of novocaine (0.5% solution) to 10 ml of the prepared solution.

How to neutralize formaldehyde? If the substance is ingested, rinse the stomach with an antidote orally. Formaldehyde antidote (antidote) - a solution of ammonium chloride or carbonate (3%).

Therapy of formaldehyde poisoning is determined by the symptoms, the route of entry of the toxic substance into the body and the characteristics of the clinical picture. The victim may be shown drugs that normalize cardiovascular activity, respiratory stimulants and sedatives.

Prevention of formaldehyde poisoning

It is impossible to completely protect yourself from formaldehyde, because. substance (in small doses) surrounds a person literally everywhere.

Regular airing of the premises, carrying out wet cleaning, maintaining the optimum temperature and humidity in the housing will help reduce the negative impact of the drug. You can start plants that neutralize toxic substances (including formaldehyde) in the air: ivy, ficus, fern, dracaena or chamedorea.

Recently, our plastic grille has received attention - the one that covers the air duct for the breather from the street. “Does it emit formaldehyde and is it dangerous?” the user asked. So we knew it was time to talk about it. So, formaldehyde in questions and answers (they also wrote about the grate).

What is formaldehyde and why is it needed?

The most natural state of formaldehyde is a gas. But it is easily soluble in liquids, and this property is readily used in industry. For example, an aqueous solution of formaldehyde is necessary for the production of materials from compressed wood: plywood, chipboard and fibreboard (chipboard and fiberboard), MDF. You can often hear that new furniture smells of formaldehyde. In fact, she smells not only of them. Any new table or chair is a whole bunch of substances and smells. However, formaldehyde really takes the lion's share there. In general, if you want to get some idea of what formaldehyde smells like in furniture, go to any specialty store.

Formaldehyde is also used in the production of plastics and resins, paints, textiles, leather products, detergents and shampoos. Formaldehyde is a strong preservative, which is why it is used in food and cosmetic products (very often in nail polishes).

Where does formaldehyde come from?

For industrial needs, it is obtained from methane and methanol.

But formaldehyde is also found in the atmosphere. There it appears as a result of photochemical reactions and processes of transformation of organic compounds (methane, methyl alcohol, etc.). A huge amount of formaldehyde is released into the atmosphere due to human activities. Road transport, chemical plants, waste incinerators, woodworking factories are all sources of formaldehyde in outdoor air. Tobacco smoke and other combustion products are “rich” in formaldehyde.

Is there formaldehyde in my apartment?

You can only answer for sure after chemical analysis air in a particular room. However, with a high degree of probability it can be assumed that the level of formaldehyde in many apartments is higher than desired.

Where does formaldehyde come from in the apartment? First, it penetrates with the air from outside. Secondly, it appears indoors from various objects that make it stand out.

Many finishing materials: PVC windows and ceilings, some types of wallpaper, floor coverings, skirting boards. All of these can emit formaldehyde for a long period of time.
Furniture made of plywood, chipboard, fiberboard, MDF emits formaldehyde for some time, from several days to several months, depending on the quality of the material from which it is made.
Everyday items: furniture, toys, appliances, stationery, dishes, etc.

Is formaldehyde dangerous?

Definitely yes. In Russia, it belongs to the second (out of five) hazard class - highly hazardous substances. The harm of formaldehyde to health has long been proven. The World Health Organization has included it in the list of substances that can cause health problems.

The degree of danger of each particular item depends on:

Degrees of emission (emission) of formaldehyde from this item.
The better the furniture or toy, the less formaldehyde they emit into the apartment. Size, by the way, also matters. Let's say a plastic handle emits less formaldehyde than a chair made from exactly the same material, simply because it's small.
time of exposure to the substance.
Half an hour of playing with a plastic doll will not harm a child's health. And ten years surrounded by vinyl wallpaper, plastic cabinets, unsafe adhesive-backed carpets and chipboard furniture? Here, unfortunately, one can only speculate, because to measure the real harm to health outside laboratory conditions difficult. However, the assumptions will be far from optimistic. Obviously, the less formaldehyde a person inhales, the better (even if the rate of formaldehyde in the apartment is not exceeded).

In 2014, the MACs for formaldehyde in the air were revised upwards. This indicates a deterioration environmental situation, and that low concentrations are difficult to achieve in residential areas with many laminated wood and plastic products.

Formaldehyde in the air is harmful primarily to the mucous membranes and skin. It causes irritation, itching, rash. Other common signs of formaldehyde poisoning from furniture and other items are lethargy, frequent sleep disturbances. Regular inflammation of the eyes and skin manifestations are also possible.

Formaldehyde is listed as a carcinogen, so constant contact with this substance dramatically increases the likelihood of cancer.

Children are more sensitive to environment, therefore, the effect of formaldehyde on the child's body is more noticeable. In general, the symptoms of formaldehyde poisoning from furniture or toys are basically the same as in adults. Of course, formaldehyde concentrations in quality items are minimal, however, as mentioned above, when it comes to many years of continuous exposure, even minimal concentrations cause serious concern.

Some studies have linked asthma in children to formaldehyde exposure.

How to measure the level of formaldehyde in the apartment?

It will not be possible to measure formaldehyde in an apartment using home methods. This requires an appropriate device (gas analyzer) and a specially trained person. If there is a need to check the apartment for formaldehyde in the air (for example, if the strong smell of formaldehyde from furniture raises doubts about its quality), then it is most reliable to contact Rospotrebnadzor, or more precisely, the Center for Hygiene and Epidemiology of your city or region. Or you can use the services.

How to test furniture for formaldehyde?

More precisely, how to find out how much formaldehyde is in furniture before buying?

There are rules for labeling furniture according to the content of this gas in its composition. Furniture marked E-(0) is the safest, the risk of formaldehyde emission is minimal even at high temperatures. Marking E-(1) indicates the content of 11 mg of formaldehyde for every 100 g of weight (i.e. the content of the substance in the furniture is about 0.011%). The E-(2) mark is placed on furniture where for every 100 g of weight there is more than 35 mg of formaldehyde (0.035%). This is how you can determine formaldehyde in furniture.

In addition to marking, you should pay attention to how the furniture is processed: “naked” chipboard material at the ends is highly undesirable. Edges and edges must be sealed.

Unfortunately, almost no furniture seller will most likely be able to provide you with a certificate and research results confirming the formaldehyde class. Therefore, when choosing furniture, you should pay special attention to the smell. A sharp chemical smell from furniture samples presented in the store, which have already stood there for some time, should alert you and make you think.

How much formaldehyde is eroded from furniture?

Intensive ventilation can significantly reduce the amount of fumes from furniture in the first few months. However, formaldehyde can erode over several years.

How to get rid of formaldehyde in the apartment?

Or how, at least, to reduce its content to safe limits?

Buying formaldehyde-free furniture is expensive and hard to find. But you can remove the smell of formaldehyde from furniture and reduce its concentration in the air.

Formaldehyde Forms clear, colorless solutions with a pungent odor; trioxane and paraformaldehyde are white crystalline masses. Miscible with water and alcohols. A by-product of many industrial reactions. Impurities - methanol, formic acid, water, various polymers.

As a food additive, formaldehyde is always used in the form of hexamethylenetetramine, but it can be found in many cleaning products and disinfectants, as well as in smoke, and with them get into the food product.

In the Russian Federation, formaldehyde is allowed as an antimicrobial agent and defoamer in the processing of sugar beet and in the production of yeast, the maximum residual amount is 0.05 mg/kg.

Another source of formaldehyde is MDF panels, paintwork materials, etc.

Most of the wooden furniture sold is made from wood-based materials using urea-formaldehyde resins. They are especially noticeable where fiberboard and chipboard are used.

Furniture made from plywood and solid wood, or entirely from solid wood, can also be a significant source of formaldehyde. AT this case it becomes oxidized finishing (paint and varnish, etc.) materials containing urea-formaldehydes, especially during the first six months after application.

Harm

The harm of formaldehyde

When exposed to formaldehyde, a person develops inflammation of the mucous membranes of the eyes and respiratory organs, and skin allergies are possible.

Several studies have indicated that menstrual irregularities may be related to exposure to formaldehyde at work or at home.

Formaldehyde emission

Although formaldehyde is used in a variety of consumer products, small amounts of free formaldehyde emitted are sufficient to significantly pollute indoor air. Only kitchen or bathroom furniture has the potential to raise formaldehyde levels in a living space to 0.10 ppm or more, especially when new.

Almost all wood furniture sets, including solid wood, can emit significant amounts of free formaldehyde in the living areas of homes. Typical materials used in the manufacture of furniture, in the production of which formaldehyde resins are used, are chipboard, MDF (fibreboard) and plywood. MDF is the most potent source of formaldehyde found in residential applications. It is often used in furniture as a base material covered with plywood. For wood products, these resins are used as internal adhesives.

Formaldehyde is released most intensively in a warm room with high humidity. The process of excretion of poison is exacerbated by poor ventilation.

Emission (release) of most of the unreacted formaldehyde usually occurs, depending on the product, within about 6 months. Once the bulk of the volatile formaldehyde has been released, indoor levels may be only a fraction of when products were new. Usually a reduction of 50 percent or more.

Although a significant reduction is expected, the problem of formaldehyde emission does not disappear, which means harm from formaldehyde will still remain. Significant continuous release of formaldehyde can occur as the polymer resin undergoes hydrolytic degradation. Because of this, the emission of free formaldehyde from products with formaldehyde resins can continue for an indefinite period. Therefore, in proportion to the increase in the amount of time for which it will be allocated formaldehyde, increases and its harm for human health.

Formaldehyde in the air

Indoor formaldehyde emission levels depend not only on the power and number of sources, but also on the environmental conditions inside and outside. Among them, the internal temperature and relative humidity of the air are especially significant.

Typically, in the range of 18-30 degrees Celsius, every 5 degrees rise in temperature roughly doubles the amount of formaldehyde in the air. Accordingly, a decrease of 5 degrees will cause a 50% decrease in level.

Less significant, but, however, an important effect has humidity. With an increase in relative humidity from 30 to 70%, approximately a 40% increase in formaldehyde levels can be expected.

The low relative humidity during winter in many homes in the north is one of the main reasons for the significantly lower levels of formaldehyde recorded in homes during the winter.

Formaldehyde concentration

Formaldehyde concentrations can decrease rapidly over time. The reduction time or decay rate will depend on the characteristics of the starting materials, their quantity relative to the air volume of the building, and environmental factors such as ventilation, temperature and relative humidity.

The more powerful the source and the longer it is operated, the slower the formaldehyde concentration will decrease over time. The higher the temperature, relative humidity and ventilation rate, the more the formaldehyde concentration will decrease over time. The initial rapid decline is followed by a prolonged and much slower decline. The release of formaldehyde from raw materials will never stop completely.

Benefit

Application of formaldehyde

Formaldehyde has a fast and strong microbicidal effect and is therefore a good remedy disinfection. It denatures and solidifies the protein, and only reversible addition products are formed, so the antimicrobial effect is partially restored.

What is formalin? What does formalin smell like?

Formalin is an aqueous solution of formaldehyde. Under the influence of formalin, proteins coagulate, that is, their decomposition is prevented. It is thanks to this property that it is used to preserve the necessary anatomical preparations, as well as in embalming. The morgue smells exactly like him.

Formalin smells like death. At least for me. This is the smell of the morgue, the smell of the dead and their preparations. It is with formalin that the dead are treated in order to slow down the processes of decay for some time. Formalin and its preparations process instruments in operating rooms, apparatuses, tables, etc. Formalin kills all living things. Formalin causes protein clotting. As it was correctly said above, now it is used to process stale meat and fish, and then, in order to bring down the smell of formalin, they are treated with a solution of vinegar. The meat after formalin has a whitish tint.

Formalin is used for dressing leather, in paper production.

Shoes are treated with formalin to destroy unpleasant odors and fungi.

Formalin has an irritant effect on the upper respiratory tract, and those who often deal with it suffer from chronic diseases of the nasopharynx, a violation of the bacterial flora of the intestines and genital tract.

Formalin is a combined preparation, it consists of methyl alcohol, formaldehyde and water (8x40x50%).

Formalin is a mixture of formaldehyde, water and methyl alcohol. Most of all in formalin formaldehyde, one of the derivatives of formic acid. Therefore, we can say that formalin smells of formic acid and alcohol. A killer combination in every sense. After all, formalin is used to embalm and prevent cadaveric decomposition in morgues for a reason - it destroys proteins, but does not allow them to decompose. Therefore, for many of us, the smell of formalin is associated with death, as already mentioned. And many do not tolerate this smell at all. However, it should not be tolerated - formalin is toxic and can cause serious poisoning.

Consider me a masochist, but I like its smell, when I made cold porcelain I used it. Reminds me of an apple scent.

Formalin is an aqueous solution of formaldehyde stabilized with methanol. Prevents the decomposition of proteins, is used in medicine for embalming and as an antiseptic. It is used for conservation and storage of anatomical and zoological preparations, as well as in the mortuary. It has a very strong, unbearable smell.

Formalin has a very nasty and pungent odor. It has a bactericidal effect and a good tanning effect. Formalin is an aqueous 4% formaldehyde solution. In stores, meat is often treated with it so that it does not deteriorate.

Formalin does indeed have a very strong unpleasant, pungent odor, however, when the source is removed, the odor quickly disappears. Formalin serves to preserve tissues (organics, meat, fish, bone), is used to store organic samples in medicine and biology. This is really an aqueous solution of formaldehyde, which has an antibacterial effect.

Synonyms: formalin, formaldehyde, methanal, methyl aldehyde, methylene oxide, paraform.

Formaldehyde is a colorless, highly toxic and flammable gas, slightly heavier than air. It has a pungent, highly irritating odor. Its vapors are flammable and explosive.

It is used most often in the form of an aqueous solution stabilized with methanol (formalin).

Formaldehyde is well absorbed by the lungs, gastrointestinal tract, and, to a lesser extent, the skin. People who are sensitive to formaldehyde may experience headaches and minor eye and respiratory irritation even at very low concentrations.

Formalin (HCHO) is an aqueous solution of formaldehyde. The most commonly used composition includes 40 percent formaldehyde, 8 percent methanol and 52 percent water. The smell of formalin is quite nasty, but quickly disappears. Used to better preserve organic tissues.

Formalin is an aqueous solution of formaldehyde, it is called aqueous because it consists of 52 percent water, the remaining 48 are divided into 8 percent alcohol and 40 percent formaldehyde, they use it in the mortuary, so this is the smell of death.

Sometimes, in houses of a very old, well, very old type, there is such a misfortune - a mouse crawls into a gap between the floorboards and there, under the floor, in a place inaccessible for cleaning, it dies. The mouse corpse begins to decompose. The smell of decaying mouse flesh wafts throughout the house. Now imagine (imagine! imagine!) that this mouse died in an untidy toilet like a toilet. Represented? I ask you, did you imagine this? If yes, then you know what formalin smells like.

What is formalin? This is a 35-40% solution of formaldehyde in water. If you want to know what formaldehyde is, ask a separate question.

Formalin is a 40% formaldehyde solution containing 8% methyl alcohol. It is used for disinfection, deodorization. How dangerous is formalin, is it harmful to humans? This compound inhibits the development of bacteria and inhibits the processes of decay. Formaldehyde is used industrially to produce phenol-formaldehyde resins used to glue sawdust and make plywood from it. Methanol is the cause of blindness from surrogate alcohol poisoning (see). This article will tell about the properties of formalin, the impact on a person.

formalin properties

Methanal or formaldehyde is chemical compound from the class of aldehydes. Widely used in medicine, industry, cosmetics. What is formalin used for? It has a cauterizing effect and precipitates proteins, which allows it to be used as an antiseptic.

It is used as a deodorant in the composition of Teymurovaya paste, Formidron - products used for sweating and unpleasant smell of sweat.

Note! It is believed that the use of formalin to suppress perspiration leads to blockage of the lymphatic system and the development of cancer.

For medical purposes, it serves as an antiseptic for disinfection and disinfection of various items. Causes folding of proteins of microorganisms and kills them. It is used in otorhinolaryngology for washing the tonsils, paranasal sinuses with sinusitis. However, in the arsenal of medicine there are safer antiseptics.

In the manufacture of vaccines, formalin in formaldehyde kills viruses so that only its antigenic determinants remain to develop immunity to it.

In the textile industry, formaldehyde is used to improve the properties of fabrics. It is used in leather tanning. In agriculture, it is used to disinfect the premises of livestock farms, as well as to treat plant seeds. Formaldehyde is a raw material for the production of resins, adhesives, and synthetic rubbers.

What does formalin smell like? It has a strong chemical smell. People working in cosmetic factories, the production of phenol-formaldehyde resins, develop a dullness of smell. The smell of formalin is similar to the smell of medicines and antiseptics in a hospital.

formalin toxicity

As a part of formalin two toxic substances therefore the second class of danger is assigned. The most harmful formaldehyde is a highly toxic chemical compound, classified as a second hazard class. It has mutagenic, carcinogenic, embryotoxic properties. This is a highly hazardous reagent.

Methyl alcohol has the third moderate hazard class, it exhibits a neurotoxic effect. In small doses, it can cause damage to the optic and auditory nerves and, as a result, to deafness. Formaldehyde and methyl alcohol also cause liver damage - toxic hepatitis. At the same time, jaundice develops, a cytolytic syndrome with an increase in aminotransferase enzymes.

What happens if you drink formalin? This mixture has a cauterizing effect, so erosive and ulcerative lesions of the oral cavity, esophagus and gastrointestinal tract are possible. When a mixture of formaldehyde and methanol is absorbed into the blood, hemolysis of blood cells occurs. Formalin poisoning leads to toxic damage to liver cells and their necrosis. Kidneys also suffer from intoxication, failure may develop up to a critical state and coma.

Why is formalin dangerous for humans? In factories, factories, medical institutions where formalin is used, people inhale vapors, components penetrate through the respiratory system into the body. The defeat of the respiratory tract and lungs can cause edema, cough, development of erosive processes. Constant inhalation of vapors contributes to the fibrosis of the lung tissue, and in the future, metaplasia of the epithelium is possible with the growth of altered cells - oncological diseases and cancer.

People working with this chemical develop pneumosclerosis, respiratory failure, and liver disease. Formaldehyde exhibits a carcinogenic property and causes mutations in the cells of the body, as a result of which, in the long term, the development of oncological diseases is possible.

For formalin poisoning, the symptoms are as follows:

Headache (see).
Weakness, loss of consciousness.
Nausea, vomiting.
Pulmonary edema, shortness of breath, cough.
Irritation of the skin and mucous membranes when exposed to formalin.

How to neutralize formalin?

To neutralize clothing, it is necessary to wash it with the addition of ammonia. If formalin vapors are found in a residential or industrial premises, adequate ventilation must be ensured. Using a hood gives a good result. To purify the air, plants with thick leaves such as aloe or Kalanchoe, Benjamin's ficus are used.

If there is furniture in the room, in the manufacture of which phenol-formaldehyde resins were used, constant ventilation is necessary until the concentration drops to the maximum allowable. However, it is better to replace such furniture with safe, without chipboard, where phenol-formaldehyde resins are used as an adhesive.

Neutralization of formalin when it enters the digestive tract is the business of medical personnel. Gastric lavage is unacceptable and dangerous. It is performed only in a hospital setting. To absorb a harmful substance, enterosorbents are used - Polyphepan, Polysorb, Activated Carbon,.

In a hospital, to neutralize the toxic effects of formalin on the body, antidotes to methyl alcohol are administered - ethyl alcohol. The stomach is washed through a nasogastric tube with a 150 ml Janet syringe, adding ammonia to the water.

With pulmonary edema, oxygenation is performed with ethyl alcohol vapor, which suppresses the formation of foam in the alveolar effusion. Antifoamsilane, a silicone polymer, is also used as a defoamer. When the bronchi are affected, alkaline inhalations are used using ammonia.

To heal the stomach, mucous is used, the drug Solcoseryl, raw egg white. For detoxification, the administration of crystalloid solutions is used, followed by forced diuresis with the help of diuretics. This allows you to activate the excretion of formaldehyde and methyl alcohol through the kidneys. Can be used and peritoneal dialysis, hemodialysis through filters - semi-impermeable membranes.

Prevention

In order to avoid getting formalin into the respiratory tract, it is necessary to use special respirators with a carbon filter. Furniture with chipboard contains formaldehyde, so it is advisable to buy cabinets and sofas, bedside tables without plywood.

In no case should formalin be taken orally. Keep away from children. Formalin is harmful to humans. Therefore, at enterprises using it, it is necessary to follow safety rules: workers must wear respirators to protect against inhalation of its vapors.
