The mercury fell to the ground, but the leader was fine at all, so frustrating.

Today at noon, I saw a Maxi vacuum gauge that was broken, and most of the mercury leaked out. It fell from the third floor to the first floor (chemical workshops are all open-air buildings, and the floors are all covered with nets). I told the boss, but he was fine at all. Just scan it and it will be fine! Alas, this mercury is poisonous. It will form mercury vapor and turn into very fine mercury dust. It has a specific gravity and will not evaporate like organic solvents. This will always be circulating in the air of the workshop. well!
Since it's out in the open, there's no need to make a fuss, just sweep away what you can see and dispose of it. Just pay attention to ventilation.
[Precautions and measures to be taken after mercury spillage] ◇ If a device containing mercury is broken, never come into contact with mercury. All people and pets should evacuate the scene immediately and maintain good ventilation at the scene. Never heat or burn mercury. ◇ Do not use a vacuum cleaner or broom to clean up mercury spills. Cleaning with a vacuum cleaner or broom will expand the scope of mercury contamination. ◇ Don't pour mercury down drains or trash cans. ◇ Do not wash mercury-contaminated clothing in a washing machine. ◇ If your shoes may have mercury on them, don't run around. Clothes and shoes stained with mercury may shake the mercury to other places and cause secondary pollution. Place contaminated shoes and clothing in a plastic bag, seal the bag, and turn it over to a hazmat facility. ◇ Correct way to deal with mercury spills: * Personnel handling mercury leakage should wear hats, masks, and gloves ； If the mercury droplets are large, you can roll them into a tube with slightly harder paper, or collect them with tin foil, tape paper, or moistened cotton swabs, and put the mercury droplets in a sealed bottle. ； It is worth noting that mercury is insoluble in water, so water sealing cannot effectively prevent its evaporation. The liquid surface can be covered with glycerin or 5% sodium sulfide solution to prevent the evaporation of mercury vapor. * When the mercury droplets are scattered in the gaps or are very small, an appropriate amount of sulfur powder can be used to cover them to cause a chemical reaction to form mercury sulfide. Leave them for 3-4 hours and then clean them up. The mercury sulfide is solid and cannot evaporate, thus reducing the harm to the human body. ； Or spray with 20% ferric chloride (10% bleach solution). The mercury flowing out will form an alloy of non-toxic mercury and iron. Leave it for 1 hour and then clean it. * Clean up contaminated garbage, including broken glass, put it in airtight containers and keep it properly. * Use 5%-10% ferric chloride or 10% bleach solution to flush mercury-contaminated floors. * If mercury droplets are scattered on bedding and clothes, you should find the mercury droplets as soon as possible and deal with them according to the above methods. You should also fully expose the contaminated bedding and clothes to the sun. ； If your skin comes into contact with mercury accidentally, rinse immediately with water. * The ceiling, walls, and air of the contaminated room should be fumigated with heated iodine (0.5 grams per square meter or 1 gram per cubic meter), or 0.1 grams per cubic meter of iodine should be dispersed on the ground and left for 8-12 hours. At the same time, the doors and windows should be sealed, and indoor personnel should exit. * After treatment, ventilation should be performed first before entering to reduce the human body's inhalation of residual mercury vapor. The recovered mercury shall be provided to units with disposal capabilities.
4# wbp I have also encountered a similar situation, and the solution is to boot. At the same time, we are doing a good job in publicity to make everyone aware of the dangers of mercury.
If there is sulfur in the workshop, cover the contaminated area with sulfur, and then collect it for disposal. If there is no sulfur, use a tinfoil collection container as mentioned on the 4th floor, and seal it. Do not handle it blindly to avoid secondary pollution.
Leaders usually deal with accidents by “minimizing major issues.” Maybe the leader you are talking about doesn’t understand this well.~
It's better to find some sulfur to deal with it. This thing has been kept in the workshop. In the end, you will be injured.
I remember that when I was a kid, the thermometer at home was broken and the mercury was dripping on the ground. We were still playing with it. It’s a bit scary to think about it.

Haha, the leader has not been in the workshop for a long time. The mercury has to volatilize, so you can handle it yourself. It is already good that the leader did not pursue the problem of damaged instruments. Don’t take some things too seriously. If you have safety responsibilities and financial violations, which one is more cost-effective?
Is mercury so harmful? I learned a lesson today
