When the device containing mercury crashes panic begins. It is very dangerous chemical element, with it you should not joke. Therefore it is necessary to know how to carry out demercurization (mercury neutralization) not to endanger itself and people around. Process of neutralization is rather simple, but demands time expenses. After mercury is neutralized, it is better to invite experts to make sure of lack of air pollution in its couples.
It is required to you
- - rubber gloves;
- - bank;
- - syringe;
- - copper plate or wire;
- - potassium permanganate solution (potassium permanganate);
- - iodine;
- - water;
- - rags.
Instruction
1. Latin name mercury Mercury (Merkurium) therefore process of its neutralization carries the name ""demercurization"". Demercurization should be begun with mechanical collecting the spread substance. On an open surface mercury rolls down in the balls reminding metal which are very mobile. First of all it is necessary to collect them. For this purpose it is necessary to put on rubber gloves to avoid hit of substance on skin, and by means of the syringe to collect them. It is very convenient to collect mercury by means of a copper plate or a wire. For this purpose it is necessary to smooth out a copper product and to bring the smoothed-out end to balls. They will instantly be attracted to copper. If there were suspicions that mercury got for a plinth, it needs to be removed surely. Then it is necessary to place mercury balls on a plate and the syringe in the tank filled with dense solution of potassium permanganate that there was no evaporation, hermetically to close and deliver to the dark cold place (for example, the fridge). The isolated from the environment, chemical element will not cause infection of products.
2. Now it is necessary to process a surface on which mercury flowed out. For this purpose it is necessary to dissolve iodine (10 ml) in 10 l (bucket) of water and to carefully wash up this surface (floor, a table, etc.). Then to part 30 mg of permanganate of potassium (potassium permanganate) in 10 l of water and right after washing with iodine, to wash a surface with potassium permanganate. It is better to carry out this manipulation in gloves and different rags. Rags should be thrown out after that, and carefully to wash a bucket also with iodine and potassium permanganate.
3. The room in which there was a mercury spreading needs to be aired within 12 hours that there is no its vapors left. In 12 hours, it is possible to consider that demercurization is carried out, and indoors it is possible to conduct usual activity.
4. If mercury spread in a large number, it is necessary to call crew of the Ministry of Emergency Situations. After neutralization, experts will carry out measurements by the special device on availability of its vapors. By the way, the crew can be called also after independent demercurization to make sure of lack of pollution. The isolated mercury and the syringe, together with the broken thermometer or other device, needs to be handed over in laboratory on utilization of radioactive waste or in department of emergency situations in this area.
