Mercury is a silvery-white liquid metal whose vapors are extremely poisonous. Until the 70s, its compounds were actively used in medicine. Due to its high toxicity, it has practically ceased to be used in the production of medicines.
Mercury is still used to make medical thermometers. The reservoir with mercury is placed in a hermetically sealed tube narrowed on one side. Upon contact with the skin, it begins to heat up, and the mercury expands and rises. When the temperature reaches its maximum, the substance freezes at a certain point.
A thermometer is a fairly fragile device, so it can easily break if handled incorrectly. In this case, it is necessary to carry out demercurization - to collect mercury with its further neutralization and elimination of contamination.
Broken thermometer with mercury droplets
What danger does mercury pose to humans?
Mercury is an unsafe metal that can actively evaporate at temperatures from +18ºС, and freeze only at -38ºС. Accordingly, if the thermometer bulb is damaged, there is a high probability that the vapors of this chemical element will spread throughout the house. The child will be the first to suffer. So what is the danger?
Experts have proven that mercury vapor, when ingested, settles in the lungs, brain, and stomach. They begin their negative effects three to four hours after contact. As a result, a person’s nervous system is disrupted, noises appear in the head, and dizziness occurs.

The gastrointestinal tract responds to poisoning with severe vomiting and general intoxication of the body. If mercury enters the respiratory system, pulmonary edema occurs and inflammation begins. The human body temperature rises to critical limits (40ºС).

First measures to eliminate household mercury pollution
The main condition for eliminating a hazardous metal spill indoors is considered to be efficiency. You cannot waste a minute after damaging the thermometer, preventing the harmful composition from spreading throughout the house.
- Be sure to remove all animals and children from the premises without wasting a minute.
- Ensure proper ventilation of the room by opening windows and doors so that there is a through flow of air.
- Quickly put on gloves and a respirator (a gauze bandage treated with soda solution will also work).
- To exclude possible contact with poison, you should put shoe covers or plastic bags on your feet, the latter will have to be firmly secured to the foot.
- We carefully inspect the room, after which we first collect all the glass fragments. Only then can you start cleaning.

If you fear for your health and do not want to do professional cleaning yourself, it is advisable to call the Ministry of Emergency Situations. They will perform demercurization, which involves cleaning the room from a liquid chemical element.
Rules for self-collection of mercury
Do not use a broom or vacuum cleaner to collect mercury droplets. This will give the metal an even greater opportunity to evaporate and create a high concentration of the chemical element in the air. Cleaning is performed as follows.
To get mercury out of the cracks, you can use a syringe, but then you need to place it along with all your things in a bag PHOTO: privet.club
Visual inspection
We carefully inspect the floor and surfaces that were in the zone of destruction of the mercury thermometer. If necessary, remove the baseboards and check the cracks if the floor is made of wood. If the balls end up on a rug, bedspread or other textile surfaces, they should be rolled up and placed in a sealed bag.
Before cleaning, you may even need to dismantle the floor covering PHOTO: pol-exp.com
Collection of mercury balls
Let's assume that the balls have rolled out on a smooth floor covering; under no circumstances should you press them or try to wipe them off. Take a sheet of clean white paper. Do not use pages from newspapers and magazines, as the metal is difficult to see on them. Carefully lift each ball and roll it into the middle of the sheet. We carefully collect everything, without crushing those already collected. Place the found particles into a jar of cold water and cover with a lid. Instead of a leaf, you can use adhesive tape and adhesive tape, which after collecting together with the balls we put into a container.
Adhesive tape should be used carefully, as the balls are very easy to crush PHOTO: vizhivanie.com
What does chemical treatment mean?
The use of chemicals is only justified if the balls have spread widely throughout the room, are not visible, or have been accidentally damaged. There are special kits and fillers for such purposes.

Disinfection kit options
Demercurization packages are capable of destroying the dangerous active substance mercury in any room. Only a few formulations are considered the most popular. According to experts, these products effectively cope with the problem of pollution.
- Demercurization kit DEMERKIT SKM-10 eliminates large amounts of released chemicals. Mainly intended for the rapid destruction of vapors formed in the air of a room up to 10 m².
- Demercurization kit DEMERKIT SKM-50 (laboratory) is an excellent composition that allows you to quickly get rid of toxic metal on your own. The kit includes a respirator and an indicator of mercury in the air.
- Demercurization kit DEMERKIT SKM-20 (household). Immediately after contact with mercury, the drug prevents vapor from spreading to other rooms. Designed for reusable use.
The composition must be stored only in tightly closed packaging PHOTO: econ-hg.ru
Before using any of the chemicals to combat mercury leakage, you must carefully study the instructions that come with the kit and may be written on the packaging.
What available tools are suitable?
The most effective folk remedy that is prepared to destroy traces of mercury evaporation indoors is potassium permanganate and chlorine. After all the mercury has already been collected, it is necessary to destroy its remains on the floor. To do this, dilute potassium permanganate in an amount on the tip of a knife in two liters of water. Then pour liquid bleach, moisten a rag with this solution and walk thoroughly along the floor in those places where the metal balls were collected.

Water diluted with bleach does a good job. To do this, you will need a bucket of water (8-10 liters) and half a liter of liquid chlorine (white will do). Dip a cloth into the mixture and thoroughly wipe the infected areas. Ventilate the room and wash the floor as usual.
On a note! Before the procedure, to avoid chemical poisoning and also to protect the skin of your hands from drying out, be sure to wear a protective bandage on your face and rubber gloves on your hands.

Processing after
If the main work is completed and all the mercury is collected, this does not mean that you can relax:
- The cleaned carpet is treated with a manganese solution. It eliminates the volatile properties of vapors and slows down their action. If the coating is light, replace potassium permanganate with soda.
- Any bleaching agent is also suitable for treatment. Bleach is mixed with water in a ratio of one to five. Surfaces are treated with a damp sponge and left for half an hour. Then wash with plenty of water. The next day the procedure must be repeated.
- The room is regularly ventilated after the incident. If possible, it is better not to close the window at all for some period of time.
- The carpet needs to be beaten out in the fresh air - the sooner the better. During work, the respiratory system must be protected. It is advisable to go to non-residential premises.
- If mercury gets on clothes, it is disposed of without any regret (even if we are talking about the most favorite T-shirt).
- It is important to protect yourself as much as possible. After eliminating the incident, wash thoroughly in the shower, rinse your mouth and take a couple of tablets of activated carbon (sorbent). Now you need to drink more liquid (plain water or milk).
Important! A very popular question is how long does evaporation take. A ball of mercury with a diameter of 3 millimeters will take 3 years to completely disappear.

Consequence of demercurization: how to avoid poisoning
To avoid any health problems after treating a poisoned room, it is necessary to rinse the mucous membranes with a weak solution of potassium permanganate. You can also use regular Miramistin as an antiseptic. It is sold in any pharmacy.

It is also recommended to take a shower with antibacterial soap and wash your hair thoroughly. Remember to take the packages containing the hazardous substance outside to prevent re-exposure.
Disposal
As with other hazardous wastes, mercury thermometers cannot simply be thrown in the trash, taken to the forest, or buried in the yard. The substance they contain is extremely harmful to humans and nature - it is assigned hazard class I-II.
You need to find out where the demercurization center is located in your city and take the jar with the remains of the thermometer there. The easiest way to get this information is by calling rescuers 112.
Please note that there are government and commercial organizations that accept mercury devices for disposal. In the first case, you do not need to pay, but there may be only one such center in a large city. There are more private companies, and they are located in different areas, but for their services you will have to pay up to 2 thousand rubles (including travel for demercurization and disposal of hazardous waste). Remember that the legal entity must have the appropriate license.
Some management companies and homeowners associations enter into agreements with organizations that have the right to dispose of hazardous waste. Ask if such a service is available in your home.
Don't just throw it away, but recycle it
After collecting the mercury in a sealed container, it is not enough to throw it in the trash. The container may be damaged, after which the metal will erode out and cause many problems to other people. To prevent this from happening, you need to contact the Ministry of Emergency Situations, explaining the situation. Rescuers will definitely give the necessary recommendations.
Special eco-boxes can be used as a receiver. But they can only be used if the mercury balls are placed in a small container PHOTO: 56nv.ru
In almost every locality there are collection points for waste containing mercury. Go there and give away all things that came into contact with harmful metal.

Features of mercury collection on different surfaces
There are several ways to clean up mercury at home. The chemical can be spilled on any surface, therefore, if everything is clear with cleaning the floor, then we will look at the actions in the event that toxic balls get on furniture, carpet or metal panels, in this section.
Even the smallest balls must be collected PHOTO: topnews.ck.ua
Upholstered furniture and carpet (carpet)
If mercury particles get on upholstered furniture, you can use a syringe or a syringe with a thick spout. The metal must be sucked in so that the balls are not crushed, but smoothly move inward. They collect poison from the carpet in the same way. Then clean the infected area with a solution of potassium permanganate, and then re-treat it with any cleaning composition.
On a note! When using manganese, you risk damaging the furniture. If you overdo it with the concentration of the substance, it is possible to paint the upholstery a different color.
The poisoned part of the carpet can be cut out, of course, if this does not affect its appearance PHOTO: ru.wikihow.com
Carpet with long pile is more difficult to clean, therefore, carefully roll it from one side to the other so as not to lose the balls. We take it outside. We lay down the film and, after hanging the carpet, carefully knock out the toxic elements. We dispose of this chemical substance together with the package.

Removing mercury from the table
The table, as a rule, also has a smooth surface. Therefore, cleaning will be similar to what was done on the floor.
- Prepare a jar of cold water.
- Take a soft brush and a paper adhesive plaster.
- Sweep the balls onto the adhesive strip.
- Dip the tape with the stuck mercury balls into cold water and cover with a lid.
Be sure to look at the cabinets and shelves that can be equipped with the table. If any of the boxes were open during the incident, then the likelihood that harmful substances got there is quite high.

What can't you do?
Unfortunately, not everyone is aware of the correct actions during demercurization (that is what this process is correctly called), so very serious mistakes are often made. If mercury gets on surfaces, it is prohibited:
- use a vacuum cleaner. This method is not suitable, since the air heated by the vacuum cleaner causes the metal to evaporate more actively, and also contributes to the dispersion of fine particles of mercury throughout the room. In addition, in the future, removing mercury residues from the bag or cyclone container of the vacuum cleaner will be extremely difficult;
- Dispose of the remaining thermometer as household waste or use a garbage disposal for these purposes. Mercury belongs to the class of highly hazardous substances, therefore its disposal as solid waste is unacceptable and leads to pollution of city landfills;
- throw the mercury thermometer or the contents of a broken flask into the toilet or flush it down the drain. In this case, hazardous substances penetrate into wastewater, polluting the environment, or accumulate in a septic tank;
- take a broken thermometer and its contents with bare hands, play with mercury, or allow children or pets to come into contact with the substance;
- use a broom or brush to collect. Bristles can break large balls into smaller ones, thereby complicating their elimination. Well, if there are cracks, holes or unevenness in the floor, the elimination process may become completely impossible or extremely difficult.
What is prohibited to do if the room is contaminated with mercury

Improper handling of a toxic substance often entails the most negative consequences. Therefore, it is not recommended to do the following:
- take a chemical element with bare hands;
- use a brush, vacuum cleaner and other rough cleaning products;
- pour boiling water or steam over the poisoned area;
- wash contaminated items in the washing machine;
- reuse items that have been in contact with toxic metal;
- throw mercury into the trash or drain.

To prevent mercury from becoming a source of poisoning for your family members, you must take precautions. The main thing is to completely eliminate contact with the chemical element of all residents of the apartment or house.
Dear readers, if you have any questions about the material in today’s publication, be sure to ask them in the comments. Have you ever broken thermometers? What did you do in such a situation?
What is a mercury thermometer?
Why in the modern world do they still use such a dangerous thing and keep it at home, because there are infrared and electronic devices that are completely safe? The thing is that mercury thermometers have a number of advantages compared to all innovative technologies.
Advantages of a mercury thermometer:
- The medical device is the most accurate. Its indicators are considered to be the closest to those of the reference gas thermometer.
- A wide range of ambient temperatures at which the thermometer correctly measures body temperature. This is possible due to the special properties of liquid metal: it freezes at very low temperatures and melts at very high temperatures.
Important! Even in extreme conditions, measuring body temperature with a mercury thermometer is not difficult.
- Due to the fact that the device can be easily disinfected by immersing it completely in a special solution, it is often used in medical and healthcare institutions.
- The cost of the device is low and accessible to everyone, which is especially important for many today.
- Simplicity and ease of use are also undeniable advantages.

Unfortunately, the mercury device also has disadvantages, one of which negates all its advantages and makes the thermometer an undesirable item in a home medicine cabinet.
Disadvantages of a mercury thermometer:
- To measure body temperature accurately, you should spend 5 to 10 minutes on this process, which is not very convenient.
- The glass cone is very thin and can easily break upon mechanical contact with a hard surface. At the same time, mercury, which spreads over considerable distances, quickly turns into toxic and poisonous vapor. The consequences of such an accident (and there is no other way to describe what happened) can even lead to death.
By the way, many have already switched to using less accurate, but safer thermometers and have completely abandoned mercury thermometers. But if you are not one of these people, then you should definitely have information on how to remove mercury from a broken thermometer at home.
