I accidentally broke the thermometer in the classroom, what to do, it s been an hour

1.Collect mercury.

Use a damp cotton swab or tape paper to collect the mercury from the ground and put it in a plastic bottle with a small opening. During the collection process, move quickly, open the window, and try not to touch the mercury with your hands.

2.Add water.

Because mercury is particularly susceptible to evaporation, the addition of water prevents mercury from evaporating. Therefore, we can add water to the container that collects the mercury residue and screw the plug to minimize mercury evaporation.

3.Treatment of mercury.

Waste mercury should never be poured down the drain as it may seep into groundwater and drinking water containing heavy metals can be a health hazard. The best course of action is to hand it over to the environmental authorities.

4.Treatment of mercury residues on the ground.

There may be some mercury residue on the ground, and the treatment method is to sprinkle some sulfur powder to neutralize the toxicity of mercury. At the same time, you can open the windows for ventilation, and you can also use other exhaust devices such as electric fans to speed up the evaporation of mercury in the air.

5.Room air treatment.

When a room is contaminated with mercury, evaporated mercury vapor will be present in the air, even if the residue is disposed of immediately. Iodine wine can be fumigated indoors, and the iodine vapor will chemically react with mercury in the air to produce non-volatile iodide mercury.

6.Accelerate indoor air circulation.

In order to make the gas evaporated by mercury flow quickly and reduce the density of heavy metals in indoor air, we can take out the electric fan used in summer to blow the air, and open the window at the same time, so that the indoor and outdoor air flow accelerates. In order to make the indoor air purify quickly.

If the thermometer is accidentally broken, you must learn how to deal with it urgently, and remind your family members as soon as possible.

After the thermometer is broken, we should quickly deal with it from the following 3 aspects:

1. Take the elderly and children away from the scene

When the thermometer at home is accidentally broken, the elderly and children should be quickly taken away from the area where the thermometer is broken, so as to prevent children from eating by mistake and avoid contact with the elderly.

2. Do a good job of self-protection

Wear a mask and gloves to prevent mercury from volatilizing and seeping into the respiratory tract or breathing, and at the same time take off hand jewelry to avoid mercury contamination with the jewelry worn during the process of handling mercury, causing secondary pollution.

3. Clean up the mercury thoroughly

Because mercury is highly volatile, so to avoid excessive temperature in the house, we need to turn off the air conditioner, electric heater, etc. in the house before cleaning, and at the same time, we should immediately open the doors and windows for ventilation to reduce the concentration of mercury in the house.

Handling precautions:

When looking for broken thermometer fragments and scattered mercury particles, we can use a bright light such as a flashlight to find and collect mercury with a scrambler, cardboard to collect thermometer debris, and then put it into a closed bottle. To avoid mercury residue, we can then sprinkle some sulfur powder on the ground.

Finally, the bottle containing mercury is handed over to the pollutant management department for disposal, and the mercury must not be poured directly into the sewer or thrown into the trash, otherwise it is easy to cause serious adverse effects on the people of the town and the society.

What to do if the thermometer is broken:

1. Let the children in the house leave first, turn off the heating device in the house, open the doors and windows in the house, ventilate, maintain air circulation, and avoid mercury poisoning.

2. Wear rubber gloves to prevent exposure to mercury; Wear a mask to prevent mercury inhalation.

3. If there are sharp objects or glass shards, please pick them up carefully, put all the broken objects on a paper towel, fold the paper towel and put it in a plastic bag.

4. Determine the position of visible mercury beads, use cardboard to collect mercury beads, move slowly to prevent them from rolling away, larger mercury beads can be sucked up with a syringe, slowly injected into a plastic container with a cap, and put into a plastic bag; Or carefully collect the mercury with pieces of paper or cotton swabs and place it in a mineral water bottle with water to stop it from playing.

5. If the mercury beads seep into the carpet, stick it into the bottle with tape, and then use a flashlight to check whether there are small droplets of mercury left near the scattered place, and if possible, the sulfur powder can be sprinkled on the place where the mercury flows, and the sulfur powder will turn from yellow to brown when it touches the mercury, and the mercury sulfide will not volatilize into the air and affect health.

6. Finally, wrap the water bottle containing mercury in a plastic bag, label it, according to the garbage classification standard, all mercury waste should be put into the red hazardous garbage ** can, remember not to pour mercury into the sewer, otherwise mercury seeps into the groundwater will continue to cause pollution.

2.What should I do if I get a mercury thermometer?

First: evacuate all people and animals and prevent people from passing through the place where the mercury was spilled;

Secondly: open windows and doors;

Again: A: If the mercury is on a smooth surface such as wood, oilcloth or polished furniture, it is relatively easy to clean the mercury.

B: If mercury is sprinkled on carpets, curtains, sheets, clothing, or other rough or easily contained mercury balls, then these contaminated areas should be cut off and thrown away.

Warn!!! Don't use a vacuum cleaner: A vacuum cleaner will blow mercury into the air, increasing respiratory exposure.

Don't use a broom: a broom will sprinkle mercury.

Do not dump mercury down the drain: this can contaminate the local water source.

Do not wash clothes that come into contact with mercury: this will contaminate the washing machine and contaminated clothes will need to be thrown away.

Don't walk around in contaminated shoes: Contaminated shoes should be thrown away, walking around will enlarge the contaminated area.

3.How do you clean the mercury that has been spilled?

a.Wear rubber, nitrile or latex gloves to prevent contact.

b.The first thing to do is to pick up pieces of broken glass or spikes, collect them in sealed bags and hand them over to the health or environmental authorities.

c.Find larger pieces of mercury and use cardboard to collect the mercury: Mercury scattering will turn into mercury beads, roll quickly, and if the ground is smooth and flat, the whole house may be sprinkled with mercury, so look at every corner of the house.

d.Using a dropper or paper, carefully collect the mercury balls and place them in a sealed plastic bag.

e.For smaller particles, apply shaving cream to a small brush with a little stickiness; or tape;

Collected mercury, used brushes and tape should be sealed in plastic bags and marked for delivery to environmental protection authorities to prevent environmental pollution.

f.Optionally, but not necessarily, sulfur can be used to absorb mercury beads that are invisible to the eye. Principle: Sulfur meets mercury from yellow to brown, sulfur combined with mercury tissue mercury volatilization, but also conducive to cleaning.

Where to buy sulfur? Sulfur may be sold as a mercury absorbent and can be purchased in laboratories, industrial, or hazardous reaction processors.

g.If you don't use sulfur, you can have a dedicated environmental department measure the mercury content of the gas in your house and treat it.

Come from.

The following is how to deal with the broken thermometer:

1. Use sand to cover the place where the thermometer is broken, and pay attention to cover it carefully;

After a few minutes, carefully clean the sand, do not omit, 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 Changshutan 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.

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.

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.

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).
