What to do if the thermometer falls to the ground and breaks

The thermometer falls to the ground, gently scoop it up and pour it out.

A thermometer is a maximum thermometer that records the highest temperature ever measured by the thermometer.

After use, the thermometer should be"Back to the table", that is, take the upper part of the thermometer and throw it down forcefully, so that the mercury that has risen into the tube can return to the glass bubble. Other thermometers should never be shaken, which is a major difference between thermometers and other liquid thermometers.

Thermometer is also called"Medical thermometers"。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 a slight change, and the expansion of the mercury volume makes the length of the mercury column in the tube change significantly.

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

The lower part of the thermometer near the vacuole neck is a very narrow curved neck, when measuring the body temperature, the mercury in the vacuole, the heated volume expands, the mercury can rise from the neck part to a certain position in the tube, when the thermal equilibrium with the body temperature is reached, the mercury column is constant.

When the thermometer leaves the human body, the outside temperature is low, and the mercury shrinks in volume when it is cold, and it is disconnected in the narrow curved neck, so that the part of the mercury that has risen into the tube cannot be returned, and the height of the mercury column when it is in contact with the human body is still maintained.

1. Mercury is the chemical element mercury, which is located in the 6th period and group IIB in the periodic table, and is the only metal that exists in a liquid state at room temperature and pressure. Its chemical properties are stable, insoluble in acids and alkalis. Because of its wide range of temperature changes in the liquid state (freezing point is -39, boiling point is), and the expansion coefficient is relatively large, the change is obvious, so it is often used for temperature measurement.

2. However, mercury and mercury vapor are highly toxic, if accidentally broken, necessary measures should be taken in time to ensure that the mercury is completely eliminated. The first thing to do is to maintain good ventilation of the leak area, reduce the concentration of mercury vapor, and reduce the danger. Because it is still the same sentence, it is a hooligan to talk about harm without metering, and a small amount of mercury contact will not cause damage to the human body.

3. Secondly, the mercury should be collected as soon as possible. The most correct way is to sprinkle sulfur powder on mercury. However, the average household rarely has sulfur powder, so we can use pieces of paper or a thin object with a smooth surface to gather the mercury together and then put it in a plastic bag for disposal.

Mercury scattered in items such as blankets can be treated with adhesive tape. During the treatment process, care should be taken not to break up the mercury into smaller particles, which will complete greater pollution.

4. In daily life, if you accidentally break the thermometer, don't worry too much, don't panic too much, you can collect the mercury ball that fell on the ground, and then use a small bottle to fill it.

5. However, this interval can not be too long, too long time on the ground mercury it volatilizes into the air, so that it can no longer be collected, you can also open the window source nucleus to wear gloves, to avoid their hands, watch metal contact with mercury, if there is some fine mercury, you can choose to use ferric chloride solution, bleach solution or sulfur powder cleaning, in order to reduce the toxicity of mercury.

6. In short, if the thermometer is broken and broken, it should be cleaned as soon as possible to prevent poisoning. At the same time, you can also choose to use an electronic thermometer to talk about the split key, which is safer and more resistant to falling.

After the mercury thermometer is broken, if it is not treated in time, it may cause poisoning. The mercury thermometer is called a mercury thermometer because the liquid column in it that shows the degree is mercury, which is mercury, which is the only metal that is liquid at room temperature. The chemical properties of mercury are relatively stable, and it is liquid at room temperature, but it will still evaporate, and the mercury vapor and mercury compounds formed after mercury evaporation are highly toxic.

The mercury thermometer does not contain much mercury, about 1 gram, but when all this gram of mercury is evaporated, it can be a mercury concentration of 22 milligrams per cubic meter in a room of about 15 square meters. A person who stays in an environment with a mercury concentration of 1-3 millimeters per cubic meter for two hours can be poisoned. If the broken thermometer is not treated in time, after evaporation in the room, the concentration is so high, and if it is not treated for a long time, people will be chronically poisoned, and people will be chronically poisoned, and there will be kidney damage, digestive system, immune system and nervous system and other problems, and the harm to the human body is relatively large.

After the mercury in the mercury thermometer evaporates, it is more harmful to the human body, so when the thermometer is accidentally broken, it must be disposed of as soon as possible before it has evaporated, and dispose of it in time, so as not to let it evaporate indoors, so that it will not be poisoned.

What should I do if the mercury thermometer is broken? The first thing to do is to evacuate the family immediately, get the family and pets out of the mercury-contaminated area, and at the same time evacuate the family, ask one of the family members to quickly open all the windows in the house. Since mercury evaporates more easily at high temperatures, turn off the heating in your home as soon as possible.

Then wear rubber gloves and collect all the mercury particles scattered on the ground into an empty water bottle. Some mercury particles may be relatively small, can not be seen well with the naked eye, at this time you can take a flashlight or turn on the mobile phone lighting, and then go to the room, if there are mercury particles on the ground, it will be reflective, if you see the reflection, it means that there are small particles here, and the small mercury particles on the ground should be received into the sealed bag as soon as possible. After collecting the mercury particles, the glass shards of the thermometer are also collected.

Mercury is very polluting to the environment, and the collected mercury garbage can not be thrown away casually, but should be thrown into a special trash can clearly marked with the word waste mercury, if there is no such garbage can around the home, it must be handed over to the environmental protection department to be handed over to professionals for disposal. After throwing away the mercury garbage, wash your hands with sulfur soap as soon as possible. <>

After breaking the mercury thermometer, you should keep the room ventilated for at least one day, and the windows should not be closed, so as to minimize the chance of mercury poisoning.

Mercury thermometers are very convenient to measure body temperature, many people have them, and everyone is used to using this kind of thermometer. However, after breaking the mercury thermometer, it is more troublesome to deal with, and it may be poisoned after improper treatment, so when using the mercury thermometer, you must be careful to avoid breaking it as much as possible, or you can replace it with other safer thermometers to avoid danger.

After the mercury thermometer is damaged, it should be cleaned as much as possible to see the mercury, if it is mercury in the crack of the ground, it can not be cleaned, it should be treated with iodine. It should be necessary to pay attention to frequent opening of doors and windows, ventilation, and more than three months to completely discharge mercury from the air.

It is best to sweep up the mercury with a broom and throw it away, never touch it with your hands, pay attention to open the window for ventilation in time, in fact, there is no need to be too nervous, because the mercury content in the thermometer is very small, not enough to be fatal,

If the thermometer falls to the ground, the room should be ventilated immediately, because the mercury in the thermometer is toxic.

Buy a new one. Be careful not to hurt your hands when cleaning the broken thermometer, and wrap up the debris before throwing it away.

Mercury is toxic and volatile. When the thermometer is broken, open the doors and windows immediately to prevent mercury vapor from being inhaled. Then put on gloves to protect yourself and clean up the mercury on the ground.

After falling on the ground, the glass should be swept away in time, and the mercury that fell on the ground should be collected with hard cardboard, wrapped in a paper towel and thrown away.

After the thermometer is broken, be sure to open the window immediately to ventilate, because the mercury in the thermometer can cause poisoning. If the mercury has already flowed out, it should be cleaned up immediately.

Many people use the thermometer incorrectly and accidentally break it, which is the right way to deal with it.

When the thermometer is broken, mercury will immediately form a lot of small mercury beads when it falls on the ground or on indoor tables and chairs. Because the boiling point of mercury is low, it is easy to volatile, and after the mercury is sprinkled, it will evaporate, which will soon pollute the indoor air, and will also be absorbed into the blood through the respiratory tract, causing fever poisoning.

A mercury thermometer contains 1 gram of mercury, which falls on a 15-square-meter floor after being broken, and if the mercury is completely volatilized, the concentration of mercury in the indoor air can reach 22 milligrams of cubic meters, which greatly exceeds the allowable standard and will seriously endanger people's health.

Tips: Doctor Xiang tells you to collect the spilled mercury as soon as possible.

If the mercury thermometer is broken, wear gloves and collect the mercury as soon as possible. Use a small moist cotton swab or tape to collect the mercury scattered on the ground and place it in a small bottle that can be sealed, such as a plastic bottle such as a beverage bottle, and add a small amount of water to the bottle. It is recommended that the bottle be written with "waste mercury" and other identifying words, and handed over to the waste liquid manager of the community neighborhood committee to be disposed of or sent to the environmental protection department for special treatment.

Never pour the collected mercury down the drain to avoid contamination elsewhere.

For mercury that falls on the ground and cannot be collected completely, you can use sulfur powder (which is sold in most pharmacies) to sprinkle it on the place where the mercury is spilled. When mercury encounters sulfur, it produces a non-volatile mercury sulfide compound, which prevents mercury from volatilizing into the air, so that mercury pollution is non-existent.

After breaking the mercury thermometer at home, if it is treated in a timely and clean manner, and the ventilation conditions in the home are better, it will generally not cause mercury poisoning.

If the thermometer is broken, you can use tape to collect mercury, open the window for ventilation, and treat the part to get out of the environment.

If you accidentally break the mercury thermometer when taking your body temperature, you can use a plastic strip to glue the mercury together in time, which can reduce the volatilization of mercury in the air and reduce respiratory inhalation.

If the thermometer is accidentally broken, it is recommended that the family should leave the room in time, and also open the windows and doors to maintain indoor air circulation and avoid inhaling too much mercury. Treat the area promptly, such as using iodine to pour on mercury-exposed ground. After iodophor volatilizes, the iodine and mercury in the air can be combined to form non-toxic mercury iodide, and finally the floor is repeatedly mopped with soapy water.

If the thermometer is broken when the body temperature is measured through the mouth, if it is accidentally ingested or inhaled, it should be sent to the hospital for treatment in time. Mercury is more harmful to the human body, after the mercury thermometer is broken, avoid inhalation or accidental ingestion, and carry out appropriate treatment in time to avoid serious harm.

The mercury thermometer has a thin glass that holds mercury and is easy to break. Once the thermometer is broken, the leaked mercury may be harmful to human health. Mercury is a liquid metal with strong volatility and toxicity, and improper handling may lead to mercury poisoning in humans.
