What happens when a thermometer breaks?

It's not that serious, there's no harm in disposing of the mercury in time, it's important not to let the little ones come into contact with it, it's fun to roll around on the ground. Let's show you the characteristics of mercury:

Mercury (HG), also known as mercury, has the lowest melting point among all metals, and is the only metal that is liquid and flows easily at room temperature. Specific gravity, specific gravity of vapor. Mercury evaporates easily into the air and causes harm because:

1. It has evaporated at 0, and the higher the temperature, the faster and more evaporation; The evaporation rate increases about twice for every 10 increases, and the evaporation is more as the air moves. 2. Mercury is insoluble in water and can evaporate into the air through the water seal layer on the surface. 3. The viscosity is small and the fluidity is large, and it is easy to break into small mercury beads, which are pervasively stored in the gaps of the workbench and the ground, which are difficult to remove, and increase the surface area and evaporate a lot, forming a secondary pollution source.

4. The surface of the ground, workbench, wall and ceiling are adsorbed with mercury vapor, and sometimes, the mercury operation workshop is moved for other purposes, and there is still a problem of mercury hazards. Contamination from workers' clothing and clothing can be brought to the home and cause harm.

The most serious consequences are:

1. This thermometer of yours cannot be used anymore.

2. If you have one less or no thermometer at home, if you still want to use it, you must buy another one, if you don't buy it, you may make a mistake or even cause unpredictable consequences.

3. If you don't dispose of glass shards, they can enter your body or someone else's body at the wrong time and cause unforeseen consequences.

It's okay, you can't still access the Internet now, hehe.

The thermometer is broken and can cause poisoning if not treated in time.

Because the body temperature table is liquid mercury, which is mercury, it can volatilize into mercury vapor at room temperature, and this mercury vapor is very toxic after inhalation. Therefore, if the thermometer is broken, it needs to be treated as soon as possible, otherwise if the mercury beads fall on the ground, they will be dispersed, not collected and cleaned up in time, volatilized into the air, and entered the nervous system through the human respiratory tract.

If you accidentally touch it, Dan Za Song can also be absorbed into the human body through **, damaging the brain, damaging the central nervous system, and even causing deformities in offspring and so on. Because the maximum allowable concentration of mercury in the air is, in general, the human body can be poisoned in an environment with mercury concentrations.

The principle of a thermometer

The working substance of the thermometer is mercury. Its glass bubble volume is much larger than that of the thin tube above. Due to the influence of body temperature, the mercury in the bubble produces slight changes, and the expansion of the mercury volume causes a significant change in the length of the mercury column in the tube.

The temperature of the human body varies between 35 and 42, so the scale of the thermometer is 35 to 42, and the range of each degree is divided into 10 parts, so the thermometer can be accurate to 1 10 degrees.

When reading, take it out of the armpit or mouth, at which point the temperature of the glass bubble beneath it will decrease. In order for his readings to still be representative of body temperature, a special design had to be made, which was a very thin tube between the glass bubble and the straight glass tube, the neck.

If the thermometer breaks, immediate measures should be taken to clean and dispose of it. Here are some ways to cope:

1. Safety measures: If the mercury water in the thermometer is broken, it should be immediately left from the rupture site and away from the scene to avoid health hazards caused by inhalation of mercury vapor.

2. Ventilation: Open doors and windows and keep them well ventilated so that mercury vapor can be emitted.

3. Stop the spread of pollution: wipe the broken place of the thermometer with a damp cloth to avoid further diffusion of mercury vapor. Do not vacuum the cracked thermometer to avoid spreading mercury vapor into the air.

4. Packaging: Put the thermometer fragments and the wet cloth used to wipe them into a closed container to avoid contact with mercury vapor from the outside world as much as possible.

5. Disposal: Submit the packaged thermometer fragments to the local environmental protection department or relevant departments for disposal. Do not throw thermometer fragments and wet cloths used to wipe them into the trash or discharge them into water sources to avoid polluting the environment.

In short, if the thermometer breaks, immediate measures should be taken to clean and dispose of it to protect human health and environmental safety.

There is no other way but to throw it hard to return to zero.

Mercury thermometer is a kind of expansion thermometer, the freezing point of mercury is -39, the boiling point is, the measurement temperature range is -39 °C - 357 °C, it can only be used as a local supervision instrument. It is not only simple and intuitive to measure temperature, but also avoids errors with external remote thermometers.

When using a thermometer, you must first see its range (measuring range) and then its minimum graduation value, which is the value represented by each small square. The temperature of the object to be measured should be measured by selecting an appropriate thermometer.

The vacuole of the thermometer should be in full contact with the measured object, and the glass bubble should not touch the side wall or bottom of the measured object; When reading, the thermometer should not move away from the object being measured, and the eyes should be at the level of the liquid level inside the thermometer.

After the mercury thermometer is broken, sulfur powder is sprinkled on the place where the liquid mercury flows, which can be chemically turned into mercury sulfide. Mercury sulfide will not affect health through inhalation, and liquid mercury will not volatilize into the air in large quantities and cause harm to the human body. Also pay attention to indoor ventilation.

Experts warn that if a child's hand is broken and comes into contact with mercury, he should be taken to the hospital immediately. Also, if mercury falls on the floor, don't wait for it to evaporate, and you can't vacuum it, it's better to collect it with an ordinary small shovel.

Experts believe that mercury thermometers are very dangerous, far beyond what people think. For example, if people put it in their mouth to measure their temperature, if the thermometer is broken, there is a high risk that mercury will flow into the mouth or even be swallowed.

In order to expel the mercury as soon as possible, the patient should not eat at this time, and should eat more crude fiber vegetables as soon as possible; If the mercury temperature plan is broken, it is likely to cause infection and cause inflammation; If mercury enters the human bloodstream, it can cause mercury poisoning.

Correct treatment: The spilled mercury must be collected immediately with a dropper, brush, and covered with water (preferably glycerin), and then sprinkled with sulfur powder on the contaminated area, and cleaned only after there is no liquid (generally about a week).

Generally speaking, it doesn't matter, it is toxic for mercury to enter the human body in an ionic state, and the thermometer is a simple substance that cannot be digested and absorbed even if eaten, it is not toxic, and it does not matter if it is a small amount, it can be sucked clean with a syringe, however, this mercury has no effect on health.

The amount of mercury in the mercury thermometer is very small, and the leakage of the thermometer after it is broken will not cause any damage to the human body, as long as it is not ingested by mistake or touches the wound site of the human body; At home, if it is sprinkled on the floor tiles and other dense floors, you can find some viscous soil, or even some flour, make the soil or flour into a dry paste, stick the mercury off, and then wipe it with paper, etc., and then wipe it with a damp cloth;

If it is sprinkled on the soil ground, then simply dig up the soil of the place, let the sprinkled mercury "seep" under the surface of the soil, and then pat the soil flat and compact. When it comes to environmental pollution, although this is not a "proper" way to deal with it, after all, you accidentally broke the thermometer, and the amount is very small, and it is impossible to "break the thermometer every day", so this treatment is still the easiest and will not cause harm to the environment and people's health.

The clothes are stained with mercury shavings, which are easy to remove: take the clothes outside the house, brush them with a brush, and pat them a few times, it really doesn't work, and you can solve it by slapping them on a stool.

Just put some water and rinse. The reasons are as follows:

1. The amount of mercury in the thermometer is very small, and once it falls into the water, it will sink to the bottom, and there is no possibility of volatilization.

2. After being in the toilet, it will be carried to a certain place by a large amount of water, and the end will be similar to a grain of sand.

3. Even if it is in the sewage treatment plant, there will be a sedimentation tank in the factory, and the mercury will sink to the bottom and mix in the sludge. The sludge, which contains a large amount of heavy metals, is finally disposed of.

Proper use of mercury thermometers:

1. The general mercury thermometer is a Mitsubishi structure, with a degree on one side and a scale on the other.

2. The degree is from 35 degrees to 42 degrees, and the scale is divided into 14 large grids, and each large grid represents five small grids.

3. After bringing the thermometer, hold the tail of the thermometer with your hand and turn the thermometer to the middle of the degree and scale.

4. Gently turn it repeatedly, and you will see a silver line (mercury). Look a little more and you'll see.

5. Hold the tail of the thermometer, gently shake the thermometer to make the scale of the thermometer below 35 degrees, and then put it under the armpit (silver place) for 10-15 minutes and take it out.

6. Look at the silver line along the gap between the scale and the degree, and the current temperature is in the degree.

The following is how to deal with the broken thermometer:

1. Cover the broken place of the thermometer with sand, pay attention to cover carefully;

After a few minutes, carefully clean the sand, do not miss it, and be careful not to touch the mercury;

3. Dispose of the sand and do not litter it at will;

4. Go to the hospital or a regular pharmacy and buy a new thermometer.

The following five steps should be done when the thermometer is broken:1. If the child is present, take the child away as soon as possible to avoid causing the child's physical discomfort or even poisoning.

2. Open the windows and keep the room ventilated.

3. If there is sulfur at home, you can sprinkle some sulfur powder on the broken thermometer and the surrounding area, and mercury and sulfur can undergo a chemical reaction to produce mercury sulfide that is insoluble in water, thereby greatly reducing the harm of mercury volatilization to the human body.

4. Wear rubber gloves, try not to let ** come into contact with mercury, and it is best to wear a mask again to avoid inhaling too much mercury vapor and causing poisoning.

5. Use bleach liquid (1%) to rinse the ground.
