How to deal with the broken mercury thermometer

Sihainet: thermometer is a tool commonly used by people to measure temperature. There is mercury in many thermometers. What should I do if I accidentally break the thermometer? Can smash mercury thermometer poison? Let's take a look at it with sihai.com.

What to do if the thermometer breaks

Thermometers are very useful in daily life. Usually, thermometers can measure people's temperature. Some thermometers are used to measure weather temperature. The thermometer for daily use contains mercury. Mercury is mercury, toxic, volatile, easy to cause poisoning. If you don't use a thermometer containing mercury, you don't need to worry about mercury poisoning if you break it. If you happen to use a thermometer containing mercury, you should deal with it in time if you break it.

1. If you take mercury carelessly, you should see a doctor in time

If the mercury containing items such as blood pressure meter and thermometer are broken and there is mercury leakage, they should be treated immediately. They can be sealed with water to prevent the volatilization of mercury and open the window to keep good ventilation. Others accidentally broke the thermometer and swallowed mercury when taking the oral thermometer. Although the dosage is not much, it will also cause stomatitis and acute gastroenteritis after taking it, which is manifested as oral erosion, ulcer, abdominal pain, nausea, vomiting, diarrhea, etc. they should be sent to a doctor in time, and they can drink egg white or milk after mouthwash before rescue.

2. Sulfur powder can be sprinkled when Mercury is sprinkled on the ground

When the thermometer is broken and the mercury is spilled out, don't panic at this time. The best way to break the thermometer is to sprinkle some sulfur powder on the mercury, so that the Mercury will have a chemical reaction and combine with the sulfur in the sulfur powder to form a black lump of mercury sulfide,. This does little harm to human body. Sulfur powder can be bought in some chemical reagent stores and also in drugstores. However, it should be noted that the sulfur powder should not be stored near the fire source or together with inflammables to avoid fire.

3. use a dropper to absorb mercury

If there is no sulfur powder, you can also use a rubber head dropper to suck the mercury into the pipe, and then bury it in the soil with the dropper, so that the Mercury will not volatilize, and can not be directly poured into the sewer or poured into the garbage can with other garbage.

4. Open windows and ventilate in time

Mercury is the only liquid metal at room temperature. Once the articles containing it are broken, the Mercury will evaporate and form a ball to roll down. At this time, you should first turn off all the heating devices in the room, open the windows for ventilation, then put on gloves and collect the mercury with a small shovel for deep burial. Mercury can evaporate into a gaseous state at room temperature, which is easy to be inhaled into the respiratory tract and cause poisoning. Therefore, it is better to wear a mask when dealing with mercury scattered on the ground.

Will the thermometer be poisoned if it is broken

When the thermometer is broken and the mercury falls on the ground or indoor tables and chairs, many small mercury beads will be formed immediately. Because of the low boiling point of mercury, it is easy to volatilize. If mercury is scattered behind, it will evaporate, and soon pollute the indoor air. It may also be absorbed into the blood through the respiratory tract, causing poisoning.

The maximum allowable concentration of metal mercury in the air is 0.01 mg / m3. Generally, people will be poisoned in the environment with mercury concentration of 1.2-8.5 mg / m3. A mercury thermometer contains 1g of mercury, which falls on the ground of a 15 square meter room after being broken. If the mercury is completely volatilized, the concentration of mercury in the indoor air can reach 22 mg / m3, which greatly exceeds the allowable standard, and will seriously harm people's health.

However, as long as the mercury thermometer is broken at home and handled in a timely and clean manner, and the ventilation conditions are better at home, mercury poisoning will not be caused generally.

The mercury thermometer is broken

Ground treatment method

First, open doors and windows to strengthen ventilation, reduce the possibility of mercury poisoning. Mercury is volatile. Then sprinkle some sulfur powder on the broken mercury thermometer.

Because the mercury content is less, the potted soil or flour can be used to remove the broken residue.

Skin contact treatment

Wipe with paper quickly. Wash with plenty of water. If the wound is exposed to mercury, it is recommended to see a doctor nearby.

Treatment method of eating by mistake

Heavy metal mercury can be used by drinking large amounts of milk or soy milk, egg white (containing large amounts of protein) liquid.

After treatment, it is close to medical treatment.
