2. Open all windows and use electric fans to enhance indoor and outdoor air circulation.
3. Turn off indoor heating equipment and other air conditioning systems.
4. Close the door communicating with the polluted room, isolate the polluted room from other rooms in the house, and avoid the mercury vapor from spreading to other rooms.
5. Use eye drops, syringes, bookmarks, business cards or plastic sheets to collect. Never use a vacuum cleaner, or even heat mercury in any way (because it will make mercury evaporate more easily); Do not use a broom or any towel to handle or wipe the scattered parts, so as to avoid the spread of mercury.
Extended data:
Mercury is a metal substance, which rarely exists under natural conditions, because its chemical properties are very active and volatile, which also leads to some toxic effects of mercury, which is harmful to human health. Therefore, people should try to avoid contact with mercury when handling it, so as to prevent mercury from bringing side effects to the body.
Mercury is mercury. Although it has the function of disinfection and sterilization, it is a kind of heavy metal harmful to human health. After entering the human body, it cannot be discharged naturally. Long-term use of cosmetics containing mercury will cause chronic poisoning, which will do serious harm to human nerves, digestive tract and urinary system.
If you accidentally touch the skin, it can also enter the human body and endanger human health.
The clinical manifestations of mercury poisoning include headache, dizziness, fatigue and fever. The symptoms of oral cavity and digestive tract are swelling and pain of gums, erosion and bleeding, loose teeth, pus overflowing from gingival sulcus, bad breath, nausea, vomiting, loss of appetite, abdominal pain and diarrhea.
Red maculopapules can appear in skin contact, mainly distributed on limbs, head and face. A few patients may have renal damage, and some severe patients may have symptoms of acute interstitial pneumonia such as cough, chest pain, dyspnea and cyanosis.
Generally, mercury invades the human body from the respiratory tract in the form of steam. There is little absorption by the skin, but there are more times when the skin is damaged and ulcerated. The digestive tract is basically not absorbed, so healthy people will not be poisoned by oral mercury.
Both intravenous injection and subcutaneous injection of metallic mercury can cause poisoning, and there have been reports of poisoning caused by a broken thermometer piercing the skin. Mercury vapor can easily enter the body through alveolar membrane and dissolve in blood. Generally, about 50% of inhaled mercury vapor can be absorbed by alveoli, and the rest can be discharged through exhalation.
When the concentration of mercury in the air increases, the absorption rate also increases. Mercury in blood is initially distributed in red blood cells and plasma, and then reaches all organs of the body, and the content in kidney is more, reaching 70% ~ 80% of the total mercury in the body. Mercury can enter the brain tissue through the blood-brain barrier and accumulate in the brain for a long time, especially in the cerebellum and brain stem.
It is also easy to enter the fetus through the placenta and accumulate diseases. Mercury is discharged from urine, feces, bile, milk, sweat, saliva, etc. The discharge of urine mercury accounts for about 70% of the total discharge, but the discharge of urine mercury is irregular, with a difference of about 4 times every day. After more than ten years of exposure to mercury, urine mercury can still exceed the standard.
