Housing and communal services against the snow are a favorite subject for residents of the capital in winter. There are a lot of horror stories about the process than the Moscow roads and sidewalks. Version one darker than the other. RIA news decided to find out what is included in the deicing materials (PGM), where they are made and stored. And most importantly — they are dangerous or not.

Double-layer protection

The Department of housing and communal services of Moscow invited journalists on a tour in South Butovo. On the outskirts of this area is located the largest base of storage of solid and liquid deicing materials.

At the entrance to the warehouse strike the eye as huge bags, stacked in neat rows in tiers. Each of them is stored nearly a ton of solid PGM. They are covered with snow, it seems that through unreliable burlap all precipitation fall inside. Citizens and on this occasion sounded the alarm: they say, the quality of the material suffers and even worse, all the soil away, causing environmental damage to the surrounding area.

We stand between the neat rows of bags. For clarity, one of the bags decided to reveal. For the first fabric layer immediately very dense layer of plastic film. When loading by crane cling to the burlap, lift up above the car, rip open the bottom, and the contents poured into the body. On average, one car holds eight bags.

What is arsenic?!

The composition of the PGM — annual headache of residents of the capital, which scare suspicious environmentalists. The latter often «wanted» in the ingredients mixture hazardous chemical. «Even arsenic are trying to find,» laughs the representative of the press service of the Department of housing.

The base area is 1200 square meters. Bags with PGM filled every corner. Around town 40 similar repositories. Dorozhniki assure that reserves will last for the entire season.

Until the severe frost, the roads and flyovers, water the liquid «protivogololodnych». Solid PGM sprinkled on the capital’s roads, when the frost grows stronger and the temperature drops below minus 10 degrees.

«Sleet is formed mainly on bridges and overpasses, so we have to process all these places. We do not heat the snow, do not allow him to adhere to. If there is GMP, it forms a water film and to get into a restaurant on the road which then just swept away. Then we are again treated to keep the water from freezing,» shares the intricacies of the process Sokolov.

In the day of our visit to base has been used in liquid PGM. Car one after another drove up to the huge tank at the point of dispensing.

«Pickle» and «the soup»

Liquid anti-icing material is produced in a small factory near Lyubertsy. It consists of the same components, and solid.

Salt from bags is dumped into huge open tanks, and then it poured the hot water, the resulting «brine» is piped into the tank where you add the next ingredient is a liquid calcium chloride. At the factory this upcoming mix called «soup».

«At a certain temperature, pressure, mix all the components, observing the proportions. And the finished product sent around the bases» — says the Deputy Director of the plant for the production of GMP Basil Spenco.

At each stage of the preparation of «soup» special laboratory controls the quality of both ingredients and finished product.

«Here on this device we check the freezing point of our GMP. According to his testimony, the solution begins to crystallize at minus 40 degrees. Although according to normative documents enough minus 32. This means our product is better quality,» — explains the head of chemical analytical laboratory Maria Salakhova, demonstrating the equipment.

Production at the plant is fully automated and is not harmful to the environment. Per day it produces 500 tons of «borscht.» Just for the winter season and the city needs 157 thousand tons. Therefore, the stocks are replenished throughout the year.

From year to year with the first snow start to argue about the use of salt for treatment of roads, saying, and cars, and shoes it spoils. The utility in response to the shrug — alternatives to these types of PGM, which would be as harmless and inexpensive, not yet invented.
