Advice 1: How to identify mercury vapor

Mercury is the only metal which under normal conditions represents a liquid. It is used in the measuring devices, vacuum pumps. Compounds of mercury are used as substances, detonators, as well as in health and agriculture. All known fluorescent lamps is also lit by pairs of mercury. This substance is still used in hydrodynamic bearings are subjected to particularly heavy loads. How do you find them in the air?
How to identify mercury vapor
There is a simple and visual way, based on the qualitative reaction of mercury with iodide of copper. The formed substance with the formula Cu2(HgI4) has a pink-red color. The higher the concentration of mercuryis, consequently, more intense coloring it.
To produce the indicator, you will need a porous filter paper, any soluble salt of copper, for example, chloride, sulfate, a salt solution of potassium iodide or sodium iodide, and a solution of sulphite or hyposulphite of sodium.
Paper cut into strips (size is unimportant, but smaller is better), dipped in solution of salt of copper, after which it is removed, slightly dried, and dipped in solution of salt of iodine. The copper iodide formed will be mainly in the pores of the filter paper and iodine on the surface for his paper "boburiy". Then the strips are placed in a solution of sulfite (hyposulphite) of sodium. Iodine is removed (this is evident by the discoloration of the paper). The strips should be washed in clean water, dry. They're ready. It is advisable to store them in a dark place, in closed containers.
If there is a suspicion that in the air there are pairs of mercury, it is necessary to put one strip in each check area. After a few hours, check for any changes. If it was pinkish-red is alarm. So, there is in the air mercury! It is necessary to take measures for detection and removal of the source of this poison.
Useful advice
Mercury vapor is extremely poisonous, causing severe illness of a number of organs of the human body. Many residents and guests of St. Petersburg, St. Isaac's Cathedral admiring without even suspect that a few dozen people involved in the gilding of the dome, has died or become disabled, because in this work the method was used amalgam (with mercury). Even a single mercury thermometer broken in the apartment, can cause trouble. The more that mercury vapors are odorless and until then you can't see remind.

Advice 2: How to clean floors from mercury

If you broke a thermometer with mercury or a mercury lamp, you should not panic, the situation is not very dangerous. You just need to collect all the balls of mercury from the surface. More complicated when mercury slipped into place in inaccessible places, for example, in the cracks of the floor or under the plinth. Gradually it will begin to evaporate and the pair may already lead to poisoning. That's why you need to try to find all the balls of mercury and collect them as soon as possible.
How to clean floors from mercury
You will need
  • - potassium permanganate
  • - chlorine tool
  • - sulfur
  • thin metal plate
  • brush
  • - rubber bulb
  • - tape or wet swab
First make sure you open a window leaf or a window to lower the room temperature because the lower the temperature, the less mercury evaporates.
Then ask people to leave the room in which you must collect mercury from the floor. Close the door, so as not to spread the mercury balls all over the apartment. At the entrance to the room, lay the rug, treated with a solution of potassium permanganate.
Now you can safely proceed to demercurization. Decontamination is the prevention of evaporation of mercury. You can adopt several methods:Now more and more there are sets that neutralize domestic mercury pollution. Attached instructions will help you to do everything correctly step by step. This kit should be kept in the home medicine Cabinet.
If you don't have demercurization kit, large beads tassel collect in paper envelope. Rubber bulb uberite smaller balls, and duct tape or wet swab, collect the small droplets. Collected mercury in a tightly close jar. Then rinse thoroughly and treat it with a solution of potassium permanganate.
If the mercury fell in places where it is difficult to remove, use the old-fashioned way - cover them with sulfur. If you have no sulfur, then use a thin plate of metal and put it in the slot. Balls of mercury "will be drawn".
If mercury were on soft things, shake them, and then within 4 months ventilate air.
After extraction of mercury, it is necessary to wash the floor. The most affordable and effective way - a solution of soap and soda (500 g of soap, 600 g of baking soda into 8 liters of water). Effectively treat the floor and walls 1% iodine solution, which can be obtained by purchasing a 10% solution of iodine from a pharmacy and dilute it at a ratio of 100 ml per 1 liter of water. Also it would be good to clean the surface of any chlorine-containing agent.
Important! Do not collect beads of mercury into one big ball.

Do not vacuum! The cleaner, when heated, increases the area of evaporation of mercury, and got him the drops will then be distributed in the form of vapor.
Useful advice
And remember! In no case do not throw mercury in the trash cans and toilet.

In a well-closed glass jar, take the mercury to the SES.
