What if I break the mercury thermometer? Will it be harmful?

In daily life, when the thermometer is damaged or leaks water and silver, the convenient and correct methods are as follows: the spilled mercury drops can be recovered with tin foil (or cigarette wrapping paper), put into a bottle and sealed with water; Or immediately sprinkle sulfur on the mercury beads to make them react to form irregular mercury sulfide solid, and then put the solid into a glass bottle and seal it for storage. Broken mercury thermometers and collected solids must never be thrown into the dustbin.

In a room polluted by mercury, I 1g/m3 and alcohol are used to ignite fumigation, or I1g/m3 is used to disperse on the ground for 8- 12 hours, so that volatile or sublimated iodine and mercury in the air can generate less volatile mercury iodide, which can reduce the concentration of mercury vapor in the air. 5%- 10% ferric trichloride or 10% bleaching powder supernatant can also be used to wash the ground polluted by mercury, which has certain mercury removal effect. Once the mercury thermometer breaks and someone shows symptoms of poisoning at the scene, the poisoned person should be evacuated from the scene immediately to a place with fresh air and good ventilation, and call for help to "120"; If you have difficulty swallowing, you should fast and eat together.
